Gas: ILF signs IIFC contract


The Infra­st­ruc­tu­re Invest­ment Faci­li­ta­ti­on Com­pa­ny (IIFC) of Ban­gla­desh has con­trac­ted ILF to car­ry out a lar­ge-sca­le fea­si­bi­li­ty stu­dy and to deve­lop the con­cep­tu­al and ten­der design for the repla­ce­ment, moder­niz­a­ti­on and auto­ma­ti­on of the gas trans­mis­si­on and dis­tri­bu­ti­on net­work of Bangladesh’s capi­tal Dha­ka and the city of Narayanganj.

The exis­ting gas net­work has orga­ni­cal­ly grown over several deca­des, without any over­all con­cept, and is no lon­ger able to satisfy the deman­ds of the mil­li­ons of indus­tri­al and domestic users in the area. The objec­ti­ve of this inte­res­ting pro­ject is to have a modern and reli­able gas net­work that enab­les remo­te moni­to­ring and con­trol at junc­tions and end points, with the pos­si­bi­li­ty of trans­forming the exis­ting net­work into a “smart” grid. The moder­niz­a­ti­on of the net­work makes a key con­tri­bu­ti­on to the achie­ve­ment of the Sus­tainab­le Deve­lo­p­ment Goals (SDGs) in Bangladesh.

ILF is loo­king for­ward to deve­lo­ping this deman­ding pro­ject and is plea­sed about being able to impro­ve the qua­li­ty of life for the popu­la­ti­on in Bangladesh.

ILF partner in Hydro4U


Hydro4U is an EU pro­ject fun­ded under the Hori­zon 2020 rese­arch and inno­va­ti­on pro­gram. In this pro­ject, ILF and 12 other part­ners from eight coun­tries are working tog­e­ther under the coor­di­na­ti­on of the Tech­ni­cal Uni­ver­si­ty of Munich to deve­lop solu­ti­ons which boost sus­tainab­le small-sca­le hydro­power in Cen­tral Asia. Two pionee­ring hydro­power types shall be imple­men­ted in demons­tra­ti­on plants in Kazakh­stan and Uzbekistan.

To this day, small-sca­le hydro­power remains lar­ge­ly unharnes­sed in Cen­tral Asia. Yet the­re is gre­at poten­ti­al to trans­fer Euro­pean small-sca­le hydro­power sche­mes to Cen­tral Asi­an regi­ons. So far the­re are only few Euro­pean refe­rence pro­jects in this regi­on as they tend to be con­si­der­ab­ly more expen­si­ve than tho­se of Asi­an competitors.

The Hydro4U pro­ject will now adjust two inno­va­ti­ve tech­no­lo­gies deve­lo­ped in Euro­pe to the requi­re­ments in Cen­tral Asia. The aim of this pro­ject is kee­ping the cos­ts as low as pos­si­ble through con­cept sim­pli­fi­ca­ti­on, modu­la­riz­a­ti­on and stan­dar­di­z­a­ti­on without com­pro­mi­sing effi­ci­en­cy. At the same time, the pro­ject also focu­ses on key aspects such as sus­taina­bi­li­ty, envi­ron­men­tal com­pa­ti­bi­li­ty and social acceptance.
In the cour­se of the Hydro4U pro­ject two eco-friend­ly demo hydro­power plants will be instal­led and asses­sed: one low-head plant with a capa­ci­ty of up to 500 kW in Kazakh­stan and one medi­um-head plant with a capa­ci­ty of approx. 2 MW in Uzbekistan.

Pro­ject dura­ti­on: 06/2021–05/2026

Coun­tries invol­ved: Aus­tria, Bel­gi­um, Ger­ma­ny, Kyr­gyzstan, Spain, Sri Lan­ka, Switz­er­land, Uzbekistan

ILF designs tunnel and open-track section for railway line


As part of the new rail­way line bet­ween Kös­ten­dorf and Salz­burg, an effi­ci­ent con­nec­tion will be built as an addi­ti­on to the 150-year-old exis­ting line. The 21.3 km long rail­way line is being plan­ned by ILF wit­hin the frame­work of two joint ven­tures (open-track sec­tion and tun­nel), with the 16.5 km long Flach­gau tun­nel com­pri­sing the key element.

The open-track sec­tion befo­re and after the tun­nel has a total length of 4.3 km and cros­ses the Fisch­ach tubu­lar bridge which has a span of approx. 42 m.
The plan­ned Flach­gau tun­nel will have two sin­gle-track tun­nel tubes. The design ser­vices will be car­ri­ed out using the BIM method and shall, in addi­ti­on to the ear­ly ser­vice pha­ses, also inclu­de the opti­on for the ten­der and con­struc­tion design tog­e­ther with the geo­tech­ni­cal engi­nee­ring on site as well as the main­ten­an­ce plan­ning. This tun­nel, which will be con­struc­ted and advan­ced under­ne­ath the exis­ting line using the New Aus­tri­an tun­ne­ling method (NATM), a tun­nel boring machi­ne (TBM), the cut-and-cover method and box jacking, is a very chal­len­ging assign­ment with com­plex plan­ning and design works.

ILF loo­ks for­ward to deve­lo­ping this deman­ding project.

ILF becomes involved in North Caspian Offshore Project


As part of a joint ven­ture with two part­ners, ILF was awar­ded a 5‑year frame­work con­tract by the North Caspian Ope­ra­ting Com­pa­ny B.V. (NCOC) for the North Caspian Off­shore Pro­ject – the first major off­shore oil and gas deve­lo­p­ment in Kazakhstan.

The pro­ject com­pri­ses five fiel­ds: Kas­ha­gan, Kalam­kas Sea, Kai­ran, Akto­ty and Kas­ha­gan South West. The giant Kas­ha­gan field is one of the lar­gest oil dis­co­ve­ries of the past four deca­des, con­tai­ning appro­xi­mate­ly 9–13 bil­li­on bar­rels of reco­ver­a­ble oil. The com­bi­ned safe­ty, engi­nee­ring and logisti­cal chal­len­ges in this har­sh off­shore envi­ron­ment make Kas­ha­gan one of the world’s lar­gest and most com­plex indus­tri­al pro­jects cur­r­ent­ly being developed.

The scope of ILF work inclu­des con­cep­tu­al stu­dies, pre-FEED and FEED deve­lo­p­ment and other services.

Expansion of wastewater treatment plant Frankfurt/Main (GER)


The Stadt­ent­wäs­se­rung Frank­furt am Main (SEF, ent­rus­ted ILF Con­sul­ting Engi­neers tog­e­ther with a Ger­man part­ner to plan, exe­cu­te and imple­ment the expan­si­on of the Nie­der­rad Was­te­wa­ter Tre­at­ment Plant (WWTP).

The Nie­der­rad WWTP is cur­r­ent­ly reaching its maxi­mum design capa­ci­ty of 1.35 mil­li­on PE. The expan­si­on is the­re­fo­re urgent­ly requi­red in order to be pre­pa­red for future deve­lo­p­ments in the con­stant­ly gro­wing Frank­furt area. For this rea­son, the num­ber of secon­da­ry aera­ti­on tanks (with a volu­metric capa­ci­ty of 7,200 m³ each) will be incre­a­sed from 8 to 10, and the num­ber of secon­da­ry sedi­men­ta­ti­on tanks (with a volu­metric capa­ci­ty of 1,875 m³ each) will be incre­a­sed from 32 to 40. The pro­ject com­pri­ses the smooth inte­gra­ti­on of the­se new tanks, as well as the asso­cia­ted mecha­ni­cal, electri­cal and SCADA equip­ment, into the exis­ting plant while main­tai­ning con­ti­nuous plant ope­ra­ti­on and com­pli­an­ce with efflu­ent requirements.

Addi­tio­nal­ly part of the assign­ment are the re-rou­ting of exis­ting pipe­work and the con­struc­tion of an access road.

ILF will be invol­ved in all eight ser­vice pha­ses of this pro­ject, which are in accordance with the Ger­man Offi­cial Sca­le of Fees for Ser­vices by Archi­tects and Engi­neers (HOAI), inclu­ding the buil­ding per­mis­si­on app­li­ca­ti­on as well as con­struc­tion super­vi­si­on and com­mis­sio­ning. The com­ple­ti­on is sche­du­led for Febru­a­ry 2027.

ILF and GEV sign MOU for hydrogen project


ILF Con­sul­ting Engi­neers and Glo­bal Ener­gy Ven­tures (GEV) have signed a Memo­ran­dum of Under­stan­ding (MOU) to iden­ti­fy and deve­lop green hydro­gen pro­jects in Euro­pe and Aus­tra­lia that inclu­de a com­pres­sed hydro­gen (C‑H2) genera­ti­on and trans­por­ta­ti­on solu­ti­on, offe­ring a valu­able addi­ti­on of mari­ne trans­por­ta­ti­on to the H2 value chain.

ILF will design the upstream infra­st­ruc­tu­re from the pro­du­cer to the export or loading faci­li­ty and the down­stream infra­st­ruc­tu­re from the import or unloading faci­li­ty to the con­su­mer, while GEV will cover the port-to-port trans­por­ta­ti­on of hydro­gen using com­pres­sed gas­eous hydro­gen ships. For pro­jects that invol­ve impor­ting hydro­gen from regio­nal mar­kets in clo­se pro­xi­mi­ty to Euro­pe, such as the Midd­le East and North Afri­ca regi­on, GEV has iden­ti­fied an oppor­tu­ni­ty to leverage off­shore loading capa­ci­ty and deve­lop a com­pres­sed gas­eous hydro­gen solu­ti­on for the off­shore wind indus­try. Thus, a fleet of ves­sels could pro­vi­de an off­shore loading and trans­port solu­ti­on for are­as whe­re an sub­sea cable or pipe­line on seabed is not suitable.

Jens Kott­sie­per, ILF Busi­ness Deve­lo­p­ment Mana­ger, com­men­ted, „The trans­por­ta­ti­on of lar­ge volu­mes of gas is an issue that ILF has been invol­ved with for over 50 years. We are plea­sed to be able to com­ple­ment our pipe­line exper­ti­se with GEV’s exper­ti­se in the cost-effec­ti­ve trans­port of hydro­gen by ship. Working with GEV will allow us to pro­vi­de our cus­to­mers with even more com­pre­hen­si­ve advice on their trans­por­ta­ti­on issu­es in order to deve­lop a solu­ti­on that meets their spe­ci­fic needs.”

ILF wins tunnel design contract for Schaftenau-Radfeld section


Wit­hin the frame­work of the upgrade to four-track ope­ra­ti­on of the Nort­hern fee­der line to the Bren­ner Base Tun­nel, ILF Con­sul­ting Engi­neers and a part­ner were com­mis­sio­ned by ÖBB INFRA to car­ry out the ten­der and con­struc­tion design as well as the geo­tech­ni­cal engi­nee­ring on site for the pri­ma­ry lining of the approx. 2.5 km long Angath tun­nel. Once com­ple­ted, the Angath tun­nel shall ser­ve as the res­cue tun­nel for the 11.5 km long Anger­berg tunnel.

The Schaftenau–Radfeld sec­tion is part of the nort­hern fee­der line of the Bren­ner Base Tun­nel and the­re­fo­re con­sti­tu­tes an essen­ti­al part of the most important North-South rail­way link in Euro­pe. The Anger­berg tun­nel situa­ted near Wörgl is the key ele­ment of this upgrade.

The ent­i­re design ser­vices shall be car­ri­ed out using the BIM method and shall also inclu­de the opti­on for the ten­der and con­struc­tion design tog­e­ther with the geo­tech­ni­cal engi­nee­ring on site for the 2.9 km long sec­tion of the twin-track Anger­berg tun­nel. A sequen­ti­al exca­va­ti­on method (NATM) is plan­ned for the tun­nel structures.

ILF has alrea­dy been invol­ved in the pre­vious design pha­ses and now con­ti­nues to work on this chal­len­ging pro­ject in the next design phases.

„Scaling up Green Hydrogen in Europe”


Date and time:

11:00 AM — 12:00 PM (CET) / 10:00 AM — 11:00 AM (GMT)

Green hydro­gen is incre­a­singly seen as an indis­pensable part of the Ener­gy Tran­si­ti­on. Ambi­tious tar­gets for pro­du­cing it have been set for the mid-2020s and 2030.

Many pro­jects and use cases are pro­po­sed, but how is an indus­try that cur­r­ent­ly only ope­ra­tes at the level of tens of MW going to reach GW-sca­le quick­ly – and effi­ci­ent­ly – enough? Will access to cheap ener­gy at the bounda­ries of and/or out­side Euro­pe help to make green hydro­gen com­pe­ti­ti­ve in the mid to long term, even taking the need to trans­port hydro­gen into account?

ILF, Den­tons  and Ope­ris have pro­du­ced a white paper on Sca­ling up Green Hydro­gen in Euro­pe. In it, we look across the hydro­gen value chain and con­si­der both the phy­si­cal and contractual/regulatory infra­st­ruc­tu­re that will be nee­ded to make the visi­on of a hydro­gen eco­no­my a rea­li­ty. We con­si­der how to match sup­ply and demand for hydro­gen; sug­gest pos­si­ble models for finan­cing hydro­gen pro­jects and tra­ding their out­put; and review the role of public finan­cial sup­port and other poli­cy inter­ven­ti­ons. We are opti­mistic about the pro­spects, but also rea­listic about some of the chal­len­ges facing this new industry.

We will be laun­ching the white paper at the online seminar.

After a brief pre­sen­ta­ti­on of our con­clu­si­ons, a panel of indus­try experts who are enga­ged in com­mer­cial hydro­gen pro­jects will deba­te the issu­es and share insights from their own experience.

Spea­kers from ILF, Den­tons and Ope­ris will be joi­ned by:

  • Julia Pres­cot, Chief Stra­te­gy Offi­cer and Co-Foun­der at Meri­diam Infra­st­ruc­tu­re, Mem­ber of the UK Natio­nal Infra­st­ruc­tu­re Commission
  • Roland Schul­ze, Mana­ge­ri­al Advi­ser on Low Car­bon Tech­no­lo­gies, Euro­pean Invest­ment Bank
  • Mari­nus Tabak, Plant Mana­ger, RWE

Plea­se click the „Regis­ter now” but­ton below if you would like to attend the cost-free online semi­nar, or to recei­ve a copy of the white paper when it is released.

We look for­ward to mee­ting you vir­tual­ly and to an inte­res­ting dis­cus­sion. Plea­se do not hesi­ta­te to con­ta­ct ILF if you have any questions.

Solving Iraq’s increasing water scarcity


The Minis­try of Con­struc­tion, Housing Muni­ci­pa­li­ties and Public Works of Iraq has awar­ded ILF Con­sul­ting Engi­neers a con­tract to pro­vi­de con­sul­ting ser­vices for a pro­ject that should make desa­li­na­ted sea­wa­ter avail­ab­le for 13 muni­ci­pa­li­ties in the Al Bas­rah governora­te (Iraq). During the next 30 to 40 years, it is expec­ted that the pro­ject will sup­ply more than seven mil­li­on peop­le with pota­ble water.

The pro­ject com­pri­ses a 1,000,000 m³/d capa­ci­ty desa­li­na­ti­on plant, which will desa­li­na­te sea­wa­ter taken from the Ara­bi­an Gulf in the area of the Al Fao Grand Port Deve­lo­p­ment, and a 240 km long water trans­mis­si­on sys­tem, which will trans­port the pota­ble water to nine off­ta­ke sta­ti­ons, thus con­nec­ting this new sys­tem with the exis­ting water sup­ply sys­tems of 13 muni­ci­pa­li­ties. A cap­ti­ve power plant with a capa­ci­ty of 300 MW will pro­du­ce the requi­red ener­gy to desa­li­na­te and trans­port the water.

ILF’s ser­vices are divi­ded into two pha­ses: Pha­se 1 inclu­des the fea­si­bi­li­ty stu­dy, envi­ron­men­tal scoping, con­cep­tu­al design, pre­pa­ra­ti­on of ten­der docu­ments and sup­port of con­tract nego­tia­ti­ons until award of the imple­men­ta­ti­on con­tract. Pha­se 2 ser­vices com­pri­se site super­vi­si­on and PMC ser­vices, from the start of con­struc­tion to the start of operation.


ILF signs contract for Tha-Htay Hydropower Project in Myanmar


On Decem­ber 9th, 2020, ILF Con­sul­ting Engi­neers signed an engi­nee­ring ser­vices con­tract with the Myan­mar Minis­try of Electri­ci­ty and Ener­gy (MOEE), Depart­ment of Hydro­power Imple­men­ta­ti­on (DHPI) for the 110 MW Tha-Htay Hydro­power Project.

The pro­ject uses the water flows of the Tha-Htay River, about 19 km nor­the­ast of Thand­we, Rak­hi­ne Sta­te. The pro­ject inclu­des the con­struc­tion of a 90 m high, zoned rock­fill dam, with a crest length of 618 m. Two diver­si­on tun­nels with a dia­me­ter of 10 m each will divert the water during construction.

After an inter­na­tio­nal com­pe­ti­ti­ve bidding pro­cess, ILF was awar­ded the engi­nee­ring ser­vices, which cover the review of exis­ting stu­dies, pre­pa­ra­ti­on of ten­der docu­ments and detail­ed design, as well as super­vi­si­on sup­port to the DHPI during the con­struc­tion. The con­tract will cover a peri­od of 57 months.


ILF still active at Vestfoldbanen railway tunnel project


As part of the ongo­ing Ves­t­fold­ba­nen rail­way upgrade sche­me, sta­te-owned Nor­we­gi­an rail­way infra­st­ruc­tu­re com­pa­ny Bane NOR is buil­ding 10 km of new dou­ble-track rail­way bet­ween Dram­men and Kobbervikdalen.
In 2018, ILF Con­sul­ting Engi­neers was hired by the Nor­we­gi­an con­trac­tor Vei­dek­ke Entre­prenør AS as the desi­gner of the most tech­ni­cal­ly chal­len­ging sec­tion of the pro­ject, a 290 m‑long tun­nel mined in dif­fi­cult geo­lo­gy below the ground­wa­ter table. The exca­va­ti­on com­men­ces in low cohe­si­on gla­cio­flu­vi­al depo­sits and pro­gres­si­ve­ly tran­si­ti­ons into full face rock exca­va­ti­on. Exten­si­ve ground impro­ve­ment works in the form of jet-grou­ting will be exe­cu­t­ed from the sur­face in advan­ce of the tun­nel­ling works.

Nor­way has a long tra­di­ti­on of rock tun­nel­ling, howe­ver lar­ge span soil tun­nels are not com­mon in the coun­try. ILF is able to bring exper­ti­se and suc­cess on simi­lar tun­nel designs to this project.

Initi­al­ly, ILF pre­pa­red the Ten­der Design and sup­por­ted Vei­dek­ke during the Com­pe­ti­ti­ve Dia­lo­gue com­pe­ti­ti­on. After the EPC Con­tract was awar­ded to Vei­dek­ke in Octo­ber 2019, ILF deve­lo­ped the Con­cept Design to later car­ry on with the Detail­ed Design, which is cur­r­ent­ly under­way and inclu­des a BIM model which is then inte­gra­ted into a com­bi­ned model of all the works wit­hin the contract.


Operation & safety eqpt.for Germany’s longest bi-direction tunnel


The 3.6 km long Kra­mer Tun­nel will be the lon­gest two-way tun­nel in Ger­ma­ny. It is pri­ma­ri­ly meant to relie­ve through traf­fic in down­town Gar­misch-Par­ten­kir­chen and towards Grainau/Eibsee and the federal bor­der at Grie­sen. In 2020, the Staat­li­che Bau­amt Weil­heim con­trac­ted ILF Con­sul­ting Engi­neers to car­ry out the fol­lowing design pha­ses: 5 to 9 (among others, pre­pa­ra­ti­on of ten­der docu­ments, con­tract awar­ding and site super­vi­si­on) for the instal­la­ti­on of the ope­ra­ti­on and safe­ty equipment.

The Kra­mer tun­nel will pre­do­mi­nant­ly be con­struc­ted as a mined tun­nel. Fur­ther­mo­re, the tun­nel will have two ope­ra­ti­ons buil­dings out­side and a cavern insi­de the tun­nel with a 26 m high exhaust air chim­ney. The tun­nel is plan­ned with cross pas­sa­ges acces­si­ble to pede­stri­ans and vehi­cles as escape rou­tes. More than 1,300 LED lights will ensu­re that necessa­ry ligh­t­ing is pro­vi­ded in the Kra­mer Tun­nel. 16 jet fans (55 kW each), and 2 exhaust air fans (420 kW each) ensu­re that the requi­red ven­ti­la­ti­on con­cept is implemented.

Sin­ce 2017 ILF has been suc­cess­ful­ly invol­ved in the Kra­mer tun­nel pro­ject, car­ry­ing out tun­nel­ling and road design ser­vices, pre­pa­ra­ti­on of ten­der docu­ments and risk ana­ly­sis as well as the first three design pha­ses for the ope­ra­ti­on and safe­ty equipment.


Seasonal greetings and best wishes for 2021!


Bes­i­des diver­se chal­len­ges that we faced, the year 2020 that is drawing to a clo­se also brought us many encou­ra­ging deve­lo­p­ments. All in all, a sen­se of gre­at satis­fac­tion and gra­ti­tu­de pre­vails regar­ding what we have achie­ved together.

Our sin­ce­re thanks go to our estee­med cli­ents and busi­ness part­ners for their con­struc­ti­ve cooperation.

Wis­hing you a peace­ful holi­day sea­son, and abo­ve all else, health and hap­pi­ness in the New Year 2021!


A revolution in reporting


On account of the gro­wing com­ple­xi­ty of day-to-day pro­ject work, the deman­ds on repor­ting are incre­a­sing signi­fi­cant­ly. Due to the lack of auto­ma­ted pro­ces­ses, clas­sic repor­ting is pro­ne to errors, only par­ti­al­ly up to date and time con­suming as well.

By imple­men­ting ana­ly­ti­cal soft­ware solu­ti­ons such as MS Power BI, the gre­at poten­ti­al of infor­ma­ti­on manage­ment can also be used for repor­ting. The aim is to visua­li­ze pro­ject-spe­ci­fic data both quan­ti­ta­tively and qua­li­ta­tively, and in a struc­tu­red and descrip­ti­ve man­ner. The­se pro­ject cock­pits are used for qua­li­ty assuran­ce and also for pro­ject coor­di­na­ti­on and control.
For the pro­ject, 2. S‑Bahn-Stamm­stre­cke Mün­chen (2nd Munich S‑Bahn Main Line), the Cli­ent, Deut­sche Bahn, reques­ted qua­li­ty assuran­ce for BIM in the design pha­se for various disci­pli­nes. In the cour­se of the gene­ral BIM coor­di­na­ti­on, ILF Con­sul­ting Engi­neers deve­lo­ped the qua­li­ty assuran­ce pro­cess by means of MS Power BI. In a mul­ti-sta­ge pro­ce­du­re, the qua­li­ty of the indi­vi­du­al tech­ni­cal models was eva­lua­ted and pre­sen­ted in a report. After the client’s appro­val, a uni­form work­flow, an inter­di­sci­pli­na­ry tem­pla­te and a pro­ject-spe­ci­fic user gui­de were developed.

For the pro­ject, this con­sti­tu­tes a new stan­dard of qua­li­ty assuran­ce, which has been imple­men­ted for the first time with such pro­fes­sio­na­lism and which will be a yard­stick for future projects.

The Nort­hern Fee­der Line forms part of the Trans-Euro­pean Scan­di­na­vi­an-Medi­ter­ra­ne­an Cor­ri­dor, which stret­ches from the South of Fin­land to the island of Mal­ta. The cur­rent pro­ject is loca­ted along the Munich–Verona axis and is a com­po­nent of the Nort­hern Fee­der Line to the Bren­ner Base Tunnel.

DB Netz AG has recent­ly com­mis­sio­ned ILF Con­sul­ting Engi­neers, as part of a joint ven­ture, to pro­vi­de design ser­vices for the rou­te selec­tion pro­cess invol­ving public par­ti­ci­pa­ti­on for the plan­ned Grafing–Großkarolinenfeld pro­ject area. The Grafing–Großkarolinenfeld sec­tion will con­sist of a new twin-track high-speed line run­ning from Gra­fing sta­ti­on to an area south of Tun­ten­hau­sen. As part of this joint ven­ture, ILF has also been invol­ved in the Großkarolinenfeld–Schaftenau sec­tion in Aus­tria sin­ce 2016. This sec­tion is loca­ted next to the Grafing–Großkarolinenfeld section.

The elec­tri­fied twin-track high-speed line shall pro­vi­de grea­ter capa­ci­ties for rail traf­fic and con­tri­bu­te to reli­e­ving traf­fic on the exis­ting Munich–Innsbruck rail­way line. Faci­li­ta­ting train speeds of up to 230 km/h, the new line is fur­ther­mo­re advan­ta­ge­ous for pas­sen­gers tra­ve­ling long distan­ces. The Grafing–Großkarolinenfeld sec­tion has a length of approx. 23 km and a maxi­mum lon­gi­tu­di­nal gra­di­ent of 12.5 ‰. The ent­i­re pro­ces­sing of the pro­ject has been done using BIM, star­ting from the ear­ly design stages.

Core ele­ments of the design con­tract inclu­de deve­lo­p­ment of fea­si­ble rou­te alter­na­ti­ves, envi­ron­men­tal inves­ti­ga­ti­ons and inter­di­sci­pli­na­ry rou­te selec­tion, as well as per­for­mance of a com­pre­hen­si­ve base­li­ne sur­vey and a pro­ject area ana­ly­sis. The design works will be accom­pa­nied by exten­si­ve citi­zen participation.


BIM method is also used at the Wank Tunnel


ILF Con­sul­ting Engi­neers, tog­e­ther with part­ners, was awar­ded the con­tract for the design ser­vices for the new eas­tern bypass of Gar­misch-Par­ten­kir­chen (Ger­ma­ny) by Staat­li­ches Bau­amt Weil­heim. This pro­ject will pro­vi­de traf­fic reli­ef on the exis­ting B2 federal road Munich–Mittenwald with a pre­dic­ted traf­fic volu­me of more than 30,000 vehicles/day.

An essen­ti­al com­po­nent of the approx. 5 km long city bypass is the con­struc­tion of the approx. 3.5 km long Wank tun­nel with a par­al­lel escape tun­nel at the south-wes­tern slo­pe of the Wank moun­tain range.

The design ser­vices inclu­de all HOAI ser­vice pha­ses, from the preli­mi­na­ry design to the con­struc­tion design, and are to be car­ri­ed out using the BIM method.


TuRisMo reduces the risk in road tunnels


With the imple­men­ta­ti­on of EU Direc­ti­ve 2004/54/EC, tun­nel safe­ty beca­me a cen­tral aspect in the design and ope­ra­ti­on of road tun­nels. By doing so, Aus­tria intro­du­ced a per­for­mance-based approach to tun­nel safe­ty. The Aus­tri­an tun­nel risk ana­ly­sis model (TuRis­Mo) is defi­ned in the Aus­tri­an gui­de­li­ne RVS 09.03.11, which descri­bes one of the first methods for ana­ly­zing and asses­sing road tun­nel safe­ty in a quan­ti­ta­ti­ve manner.

TuRis­Mo com­bi­nes dif­fe­rent metho­di­cal ele­ments for ana­ly­zing a tun­nel sys­tem in its ent­i­re­ty and fol­lows a holistic approach. The use of TuRis­Mo offers the pos­si­bi­li­ty of quan­ti­ta­tively record­ing and asses­sing almost all decisi­ve fac­tors influ­en­cing tun­nel safe­ty. This con­tri­bu­tes to ensu­ring that invest­ments for tun­nel safe­ty are used as cost effi­ci­ent­ly as possible.

Combining infrastructures: H2 pipelines in cable routes


For the lar­ge-sca­le dis­tri­bu­ti­on of hydro­gen in Ger­ma­ny, the Fach­ver­band der Netz­be­trei­ber (FNB) – the Ger­man Asso­cia­ti­on of Net­work Ope­ra­tors – pro­po­ses to make modi­fi­ca­ti­ons to the exis­ting natu­ral gas net­work as well as to a num­ber of new con­struc­tion projects.

A com­pa­ri­son of FNB’s pro­po­sed hydro­gen net­work with under­ground cable pro­jects in Ger­ma­ny shows that the rou­tes for the direct cur­rent trans­mis­si­on lines, which are alrea­dy in the plan­ning sta­ge, could be mea­ning­ful­ly used to com­ple­te the plan­ned H2 pipe­line net­work. In addi­ti­on, this could incre­a­se the H2 trans­port capa­ci­ties in a North–South direc­tion to appro­xi­mate­ly 10 GWh/h.

In an initi­al stu­dy con­duc­ted by ILF Con­sul­ting Engi­neers, it beca­me appa­rent that pipe lay­ing is tech­ni­cal­ly fea­si­ble wit­hin a lar­ge part of the rou­te for the power trans­mis­si­on lines, with only a few sec­tions lea­ding to incre­a­sed plan­ning and con­struc­tion cos­ts. For the smal­lest part of the rou­tes, a small-sca­le re-rou­ting of the H2 pipe­line is likely to be advi­s­able for eco­no­mic rea­sons. The next steps shall be the exami­na­ti­on of the gene­ral con­di­ti­ons, espe­cial­ly with regard to the project’s chan­ces of recei­ving aut­ho­ri­ty appro­val and a detail­ed con­si­de­ra­ti­on of the tech­ni­cal feasibility.


Railway route for commuters to Cologne is being expanded


Like many urban agglo­me­ra­ti­ons, Colo­gne is also expe­ri­en­cing incre­a­sing num­bers of com­mu­ters. In addi­ti­on, the high­ly fre­quen­ted Colo­gne rail­way loop is a cen­tral con­nec­tion point for regio­nal, natio­nal and inter­na­tio­nal rail traffic.

In order to incre­a­se the capa­ci­ty of the line and the fre­quen­cy of the trains on the line, invest­ments are to be made into the expan­si­on of Colo­gne’s local public trans­port sys­tem. ILF Con­sul­ting Engi­neers has been com­mis­sio­ned with the over­all design for the expan­si­on of the S11/S‑Bahn Main Line, packa­ge 1 “VP1” (Köln-Dell­brück to Ber­gisch Glad­bach) (

The scope of ser­vices inclu­des, among other things, the plan­ning and design of the trans­por­ta­ti­on faci­li­ties and engi­nee­ring struc­tures, envi­ron­men­tal plan­ning, sub­soil inves­ti­ga­ti­ons, the necessa­ry noi­se and vibra­ti­on inves­ti­ga­ti­ons, the plan­ning and design of the con­trol and signa­ling tech­no­lo­gy as well as over­head trans­mis­si­on sys­tems, and site super­vi­si­on during the plan­ning and design.


Can you teach an old dog new tricks?


Hydro power is com­mon­ly con­si­de­red as a matu­re tech­no­lo­gy. Does this mean that you can­not teach an old dog new tricks?

The incre­a­se in cal­cu­la­ti­on power allows us employ­ing Com­pu­ta­tio­nal Flu­id Dyna­mics simu­la­ti­ons to tailor stan­dard struc­tures to your needs and to design and test tru­ly inno­va­ti­ve hydrau­lics structures.

See in the below video how we used cut­ting-edge CFD models to re-design the Nam Emoun pro­ject in Lao PDR. The key for the trans­for­ma­ti­on of the pro­ject was the imple­men­ta­ti­on of ful­ly pres­su­ri­zed water­ways. To gua­ran­tee ope­ra­tio­nal fle­xi­bi­li­ty and hydrau­lic sta­bi­li­ty, an inno­va­ti­ve baff­led drops­haft struc­tu­re was deve­lo­ped and tes­ted. Thus, the cost of the pro­ject could be redu­ced by USD20 mil­li­on com­pa­red to the pri­or con­trac­tor offer, the ener­gy out­put was incre­a­sed by almost 10% and the con­struc­tion time was redu­ced by 8 mon­ths. CFD was key to turn a bare­ly fea­si­ble pro­ject into a high-per­for­mance invest­ment. So, Yes, you can teach an old dog new tricks.

A Sustainable Upgrade for the Schmittenhöhe Snow-Making System


After years of sear­ching in vain for an eco­lo­gi­cal­ly and eco­no­mi­c­al­ly jus­ti­fia­ble loca­ti­on for a new sto­rage reser­voir, which is nee­ded to incre­a­se the capa­ci­ty of the snow-making sys­tem in the nort­hern part of the Schmit­ten­hö­he ski area, an alter­na­ti­ve solu­ti­on, which invol­ves taking water direct­ly from Lake Zell, has been deve­lo­ped tog­e­ther with Schmit­ten­hö­he­bahn AG, one of ILF’s long-stan­ding cli­ents. ILF was com­mis­sio­ned to deve­lop a tech­ni­cal­ly fea­si­ble solu­ti­on that could be appro­ved by the aut­ho­ri­ties and to sup­port the imple­men­ta­ti­on of this solu­ti­on during the per­mit app­li­ca­ti­on design, detail­ed design and site super­vi­si­on, all the way through to commissioning.

A first con­struc­tion pha­se in 2019 inclu­ded the con­struc­tion of a pum­ping sta­ti­on at Lake Zell, which invol­ved the instal­la­ti­on of pipes via pipe jacking under the federal road, the ÖBB rail­way line and the lakesi­de pro­me­na­de, with the pipes lea­ding direct­ly into Lake Zell. Water is taken from Lake Zell and pum­ped through several pump units, at a total of 150 l/s, via an appro­xi­mate­ly 3‑km-long sup­ply line to the exis­ting Son­nalm I pum­ping station.

In 2020, the Son­nalm II pum­ping sta­ti­on was con­struc­ted during the second con­struc­tion pha­se. By means of an addi­tio­nal pum­ping sta­ti­on, the ent­i­re addi­tio­nal flow capa­ci­ty can now be used to trans­port water to the snow makers via the new power­ful coo­ling sys­tem with a total of 6 lar­ge coo­ling towers. After com­ple­ti­on and com­mis­sio­ning of the sys­tem in autumn 2020, the Schmit­ten­hö­he AG will now be able to pro­vi­de gua­ran­te­ed snow in the nort­hern part of the ski area, thanks to the power­ful snow-making system.


When rain becomes a flood


Coo­ling off in a sud­den rain sho­wer on a hot sum­mer day often feels good. But a thun­der­storm with tor­ren­ti­al rain can quick­ly lead to floo­ding and cau­se serious dama­ges in cities and settlements.
Extre­me rain­fall events are dif­fi­cult to pre­dict as they occur sud­den­ly and on a small spa­ti­al sca­le. Due to cli­ma­te chan­ge, the occur­rence of such events will very likely incre­a­se and it is advi­s­able to be well pre­pa­red befo­re they happen.

With a com­pe­tent and inter­di­sci­pli­na­ry team and with spe­cia­li­zed mode­ling tools, ILF Con­sul­ting Engi­neers sup­ports its cli­ents in pre­pa­ring and deve­lo­ping pro­tec­ti­ve mea­su­res. A key ele­ment is the hazard ana­ly­sis car­ri­ed out using a hydro­dy­na­mic model that simu­la­tes the run­off of storm­water in the drai­na­ge sys­tem and on the sur­face, i.e. on streets, squa­res, or along dit­ches and rivers, thus making it pos­si­ble to assess the asso­cia­ted risks. Based on the ana­ly­sis results, various pro­tec­ti­ve mea­su­res can be developed.

Computational Design for Infrastructure projects


Through the app­li­ca­ti­on of Com­pu­ta­tio­nal Design (CD) on infra­st­ruc­tu­re pro­jects, ILF Con­sul­ting Engi­neers breaks new ground. The approach was based on com­bi­ning the CD skills with engi­nee­ring and soft­ware exper­ti­se. Tog­e­ther, this com­bi­na­ti­on was able to reco­gni­ze the pos­si­bi­li­ties and stream­li­ne design pro­ces­ses with incre­a­sed qua­li­ty and time savings.

ILF tun­ne­ling experts used CD to crea­te opti­mi­zed tun­nel pro­fi­le designs for the crea­ti­on of buil­ding infor­ma­ti­on mode­ling (BIM) models of tun­nels based on real-world tun­nel pro­jects. Using gene­ra­ti­ve design solu­ti­ons which allow the user to set varia­bles and desi­red goals such as mini­mum exca­va­ti­on area and/or requi­red ven­ti­la­ti­on area, an opti­mi­zed tun­nel cross sec­tion is pro­du­ced and used in turn for the crea­ti­on of the BIM models.

A fur­ther examp­le invol­ved the design of tun­nel bran­ches based on inputs such as typi­cal cross sec­tion data, align­ments, gra­di­ents, chai­na­ges and cross slo­pe infor­ma­ti­on. A para­metric 3D model of the tun­nel branch geo­me­try and 2D sec­tions of the tun­nel pro­files are pro­du­ced. By redu­cing the time for pro­duc­tion of design alter­na­ti­ves to 20 %, various alter­na­ti­ves can be con­si­de­red and the qua­li­ty of the final design can be optimized.

Stuttgart 21 – a 10-year success story


ILF Con­sul­ting Engi­neers has been working on the lar­ge-sca­le pro­ject Stutt­gart 21 (S21) sin­ce being awar­ded a con­tract by the Deut­sche Bahn, at the end of 2009, to car­ry out the con­struc­tion super­vi­si­on for various sec­tions of the pro­ject. With the plan­ned con­struc­tion works, the ent­i­re floor plan of the Stutt­gart Cen­tral Sta­ti­on will be rota­ted by approx. 90 degrees and laid under­ground. This requi­res the con­struc­tion of nume­rous new inter­con­nec­tions and many modi­fi­ca­ti­ons on exis­ting lines in the inner-city area, as well as the con­struc­tion of new tun­nel sec­tions as fee­der lines to the future Stutt­gart station.

ILF’s scope of ser­vices com­pri­ses the design sec­tions 1.2 and 1.6a of the S21 pro­ject (see over­view below), which are inter­con­nec­ted to the new cen­tral sta­ti­on by tun­nels ending in the future high-speed track of the new Stuttgart–Ulm line, which is cur­r­ent­ly being con­struc­ted in the South of Stutt­gart. In addi­ti­on the­re are under­ground con­nec­tions to the exis­ting rail­way lines towards Unter­tür­keim and Ober­türk­heim in the East.

ILF’s experts have now been suc­cess­ful­ly invol­ved in this lar­ge-sca­le pro­ject for more than 10 years and will con­ti­nue to work on this pro­ject for some years to come. The com­mis­sio­ned ser­vices main­ly com­pri­se tech­ni­cal and con­struc­tion con­tract-rela­ted ser­vices as the con­struc­tion super­vi­sor, rail­way ope­ra­tio­nal ser­vices in the vicini­ty of the faci­li­ties in ope­ra­ti­on, as well as ser­vices for pro­ject com­ple­ti­on inclu­ding han­do­ver of the ent­i­re con­cre­te and struc­tu­ral works pri­or to the com­men­ce­ment of works on the track bed struc­tures being car­ri­ed out by other contractors.

So far, a total of appro­xi­mate­ly 28 km of sin­gle-track tun­nel tubes have been dri­ven using mining methods (NATM) and tun­nel boring machi­nes (TBMs). The tun­nel cross sec­tions are appro­xi­mate­ly 8 to 9 m in dia­me­ter, with under­ground bifur­ca­ti­ons as well as appro­xi­mate­ly 30 emer­gen­cy con­nec­tion struc­tures. In addi­ti­on, 3 lar­ge por­tal struc­tures are being con­struc­ted using the cut-and-cover method, each appro­xi­mate­ly 300–500 m long with trough and rect­an­gu­lar cross-sec­tions in part­ly con­fi­ned con­di­ti­ons next to rail­way lines that are alrea­dy in operation.

Cur­r­ent­ly, the last tun­nel sec­tions are being dri­ven towards Ober­türk­heim. Par­al­lel to this, the inner linings in all sec­tions of the tun­nels and the cut-and-cover works in the por­tal are­as are nea­ring com­ple­ti­on. The next major mile­stone is expec­ted to be reached by mid-2021, which will com­pri­se the initia­ti­on of the sub­se­quent track works on several tun­nel sec­tions around Stuttgart.


New Ammonia Tanks in Aqaba


KEMAPCO Arab Fer­ti­li­zers & Che­mi­cals Indus­tries Com­pa­ny in Jor­dan has com­mis­sio­ned ILF Con­sul­ting Engi­neers to pro­vi­de Pro­ject Manage­ment Con­sul­tancy (PMC) ser­vices for new ammo­nia tanks.

KEMAP­CO’s pro­duc­tion faci­li­ties cur­r­ent­ly have a pro­duc­tion capa­ci­ty of 175 Kt of pot­as­si­um nitra­te (NOP) fer­ti­li­zer and nitric acid per year, which covers appro­xi­mate­ly 8% of total glo­bal NOP demand. At pre­sent, KEMAPCO recei­ves its sup­ply of ammo­nia from a third par­ty com­pa­ny via pumps and pipe­lines. In order to incre­a­se inde­pen­dence from sup­pliers, the con­struc­tion of a new ammo­nia sto­rage tank with a capa­ci­ty of 20,000 Mt is plan­ned in the eco­no­mic zone of Aqa­ba. The pro­ject con­sists of a dou­ble-wal­led, coo­led ammo­nia sto­rage tank with loading and unloading faci­li­ties and all other rela­ted equipment.

ILF has been com­mis­sio­ned with the pro­ject manage­ment, conceptual/tender design for the EPC con­tract as well as con­struc­tion and com­mis­sio­ning supervision.


Go-ahead for the StadtRegioTram Line Extension to Kremsdorf


The Stadt­Re­gio­Tram (SRT) is an essen­ti­al com­po­nent of the over­all traf­fic and trans­port manage­ment con­cept and of the public trans­port net­work for the grea­ter Linz area, and cur­r­ent­ly runs from the city cen­ter of Linz to the city of Traun. In the future, a third exten­si­on to the line is plan­ned, with the new sec­tion lea­ding to Krems­dorf, in the muni­ci­pa­li­ty of Ans­fel­den. The first two exten­si­ons of the line have alrea­dy achie­ved a signi­fi­cant incre­a­se in pas­sen­ger num­bers com­pa­red to the fore­casts. In 2018, the annu­al num­ber of pas­sen­gers on lines 3 and 4 was 6.8 mil­li­on. On the plan­ned third exten­si­on to the SRT, appro­xi­mate­ly 12,000 pas­sen­gers are expec­ted on working days.

In August 2020, ILF, as part of a part­ners­hip and as best bid­der, was awar­ded the con­tract, by Schie­ne OÖ GmbH, for the con­cep­tu­al design of the approx. 4.4 km long exten­si­on of the line. The objec­ti­ve of the con­cep­tu­al design is to make important decisi­ons and sti­pu­la­ti­ons rela­ting to the tech­ni­cal con­tent and/or spa­ti­al extent of the pro­ject, and to assess their impact on both the envi­ron­ment and cos­ts. This should pro­vi­de a sta­ble basis for the poli­ti­cal decisi­on regar­ding the rea­liz­a­ti­on of the project.


Ski World Championships 2025 in Saalbach-Hinterglemm


For the second time, the Alpi­ne Ski World Cham­pions­hips 2025 will be held in Saal­bach-Hin­ter­glemm (Aus­tria). The Saal­bach ski resort, a long-stan­ding cli­ent of ILF Con­sul­ting Engi­neers, beat its com­pe­ti­tors, the renow­ned ski resorts Crans Mon­ta­na (Switz­er­land) and Gar­misch-Par­ten­kir­chen (Ger­ma­ny) in the run­off for the 2025 Ski World Championships.

All races of the Word Cham­pions­hips will take place at Zwöl­fer­ko­gel and the­re­fo­re on snow pro­vi­ded by snow-making sys­tems desi­gned by ILF. Congra­tu­la­ti­ons to our cli­ent! We look for­ward to exci­ting com­pe­ti­ti­ons in Saalbach.


Freestyle bike event in a class of its own – Crankworx Innsbruck


For the fourth time in a row, the world’s lar­gest gra­vi­ty moun­tain bike fes­ti­val took place in Tirol last wee­kend. The host, Bike­park Inns­bruck at the Mut­te­rer­alm, crea­ted per­fect con­di­ti­ons for the bike pros des­pi­te the incle­ment wea­ther conditions.

The vic­to­ry of two Aus­tri­an moun­tain bike riders in the down­hill race on the trails and cour­ses desi­gned by ILF made for an exci­ting finish to Crank­worx on Sunday. We look for­ward to see­ing the ath­le­tes again on the Mut­te­rer­alm at Crank­worx 2021.


More Snow for the Reiterkogel Snow-Making System in Hinterglemm


In sum­mer 2020, Berg­bah­nen Saal­bach-Hin­ter­glemm GmbH (BBSH) made the decisi­on to fur­ther expand the Rei­ter­ko­gel snow-making sys­tem. The aim of the expan­si­on is to con­si­der­ab­ly incre­a­se the system’s snow-making capa­ci­ty in order to sub­stan­ti­al­ly impro­ve snow cover and be pre­pa­red for future challenges.

The key com­po­nent of the two-year con­struc­tion pro­ject is the Ross­wald sto­rage reser­voir, with a total capa­ci­ty of approx. 230,000 m³, and the asso­cia­ted new pum­ping sta­ti­on. The dam of the sto­rage reser­voir, with a maxi­mum height of 42 m, will be con­struc­ted in its ent­i­re­ty using pro­ces­sed mate­ri­al from the reser­voir excavation.

The exis­ting sys­tem tog­e­ther with the new sto­rage reser­voir and the adja­cent pum­ping sta­ti­ons will con­tri­bu­te to high­ly effi­ci­ent water manage­ment and sys­tem per­for­mance at the Reiterkogel.

Upon com­ple­ti­on of the rena­tu­ra­liz­a­ti­on works, the Ross­wald sto­rage reser­voir will beco­me a popu­lar desti­na­ti­on for sum­mer excur­si­ons blen­ding per­fect­ly into the pic­tures­que sur­roun­dings. The reservoir’s easy acces­si­bi­li­ty makes it an ide­al spot for sum­mer tourism.

Green electricity storage facility in Gaildorf


The water bat­te­ry is an inno­va­ti­ve com­bi­na­ti­on of a wind power plant and a small and fle­xi­ble pum­ped sto­rage plant for the sto­rage and con­trol­led feed of vola­ti­le rene­wa­ble ener­gy into the grid. The first pilot pro­ject is cur­r­ent­ly under­way in Gail­dorf (Ger­ma­ny). For this pur­po­se, ILF Con­sul­ting Engi­neers was com­mis­sio­ned by Max Bögl Wind AG to pro­vi­de dif­fe­rent con­sul­ting and design ser­vices for the pum­ped sto­rage plant.

Inno­va­ti­ve solu­ti­ons and various other uni­que fea­tures cha­rac­te­ri­ze the initi­al imple­men­ta­ti­on in Gail­dorf and make this pro­ject a light­house pro­ject. The sto­rage plant has a head of 200 m. With regard to machine­ry, the inno­va­te cha­rac­ter is empha­si­zed by the 3x6 MW varia­ble speed rever­si­ble pump tur­bi­nes with asyn­chro­nous gene­ra­tor and full con­ver­ter, all of which is meant to achie­ve maxi­mum fle­xi­bi­li­ty for demand based sto­rage and feed-in of the gene­ra­ted energy.

The for­ward-loo­king pro­ject is sup­por­ted with EUR 7.15 mil­li­on fun­ded through the envi­ron­men­tal inno­va­ti­on pro­gram of the Ger­man Federal Minis­try for the Envi­ron­ment, Natu­re Con­ser­va­ti­on, Con­struc­tion and Nuclear Safety.*




Take the train, collect Green Points, protect the environment


Once again, ILF Con­sul­ting Engi­neers’ employees in Aus­tria are among the most fre­quent train pas­sen­gers in Aus­tria. By taking the train for busi­ness trips, last year ILF employees collec­ted lots of “Green Points”, a pro­gram initia­ted by the Aus­tri­an Federal Rail­ways (ÖBB), and redu­ced CO2 emis­si­ons by 86.8 tons. ILF is proud that this figu­re again repres­ents a signi­fi­cant incre­a­se from the pre­vious year (63.1 tons).

ILF great­ly appre­cia­tes this ÖBB initia­ti­ve, as the sus­tainab­le pro­tec­tion of the envi­ron­ment is extre­me­ly important both with regard to the struc­tures and faci­li­ties plan­ned by ILF and the dai­ly pro­ject work. We con­ti­nue to stri­ve to con­tri­bu­te to sus­taina­bi­li­ty in Aus­tria by taking ÖBB trains for busi­ness trips and ther­eby sup­por­ting this gre­at initiative.


Resilient infrastructure – how does that work?


Extre­me heat or snow­fall, storms, floo­ds and forest fires can have mul­ti­ple impacts on our dai­ly lives. The­se phe­no­me­na are not new but they are incre­a­sing in inten­si­ty and fre­quen­cy, and are the­re­fo­re a gre­at chal­len­ge for the resi­li­en­ce of trans­port infra­st­ruc­tu­re. The con­se­quen­ces that we all noti­ce are exten­si­ve traf­fic jams, leng­thy clo­sures, mate­ri­al dama­ge, major detours and long delays.

ILF Con­sul­ting Engi­neers is cur­r­ent­ly working inten­si­ve­ly on two rese­arch pro­jects in Ger­ma­ny, to be able to coun­ter­act the effects of ongo­ing cli­ma­te chan­ge. The resi­li­en­ce of trans­port infra­st­ruc­tu­re has to do with the avai­la­bi­li­ty of the trans­port net­work in the event of effects resul­ting from extre­me events of any kind.

The gre­at com­ple­xi­ty of the topic and the inter­con­nec­tion of dif­fe­rent aspects requi­re a high level of tech­ni­cal com­pe­tence. Just as important is the abi­li­ty to reco­gni­ze func­tio­n­al rela­ti­ons­hips and to struc­tu­re them appropriately.

The com­pe­tence and expe­ri­ence of ILF’s experts makes it pos­si­ble to imple­ment chal­len­ging pro­jects at home and abroad in the best pos­si­ble way.



Electro-mechanical challenge at the Engelberg Base Tunnel


ILF Con­sul­ting Engi­neers has recent­ly won several very inte­res­ting pro­jects in the field of elec­tro-mecha­ni­cal equip­ment for road tun­nels. One pro­ject, which deser­ves spe­cial men­ti­on, is a con­struc­tion super­vi­si­on con­tract at the Engel­berg Base Tun­nel near Leon­berg, which was awar­ded to ILF and a part­ner by the regio­nal government aut­ho­ri­ty ser­ving the Ger­man city of Stutt­gart (Regie­rungs­prä­si­di­um Stuttgart).

Due to its cen­tral loca­ti­on, lin­king the A8 and the A81 motor­way, the twin-tube tun­nel with a length of appro­xi­mate­ly 2,530 m plays a key role as a north-south and east-west traf­fic hub in sou­thern Germany.

In addi­ti­on to high­ly com­plex struc­tu­ral reha­bi­li­ta­ti­on works being requi­red due to defor­ma­ti­ons and dama­ge of the per­ma­nent lining in parts of the tun­nel, the elec­tro-mecha­ni­cal equip­ment will have to be upgraded to meet the latest safe­ty requirements.


Modeling of water resources



Water is life and a resi­li­ent infra­st­ruc­tu­re is a key ele­ment for sus­tainab­le deve­lo­p­ment and poli­ti­cal sta­bi­li­ty. For the plan­ning, design and imple­men­ta­ti­on of many infra­st­ruc­tu­re pro­jects and for a com­pre­hen­si­ve river basin manage­ment, know­ledge about the avai­la­bi­li­ty of water over space and time is an important pre-requi­si­te for decisi­on-making and design processes.

Water balan­ce ana­ly­ses depend stron­gly on sui­ta­ble soft­ware and, abo­ve all, on reli­able data on tem­pe­ra­tu­re, pre­ci­pi­ta­ti­on and dischar­ge, etc. In many regi­ons of the world, the qua­li­ty and quan­ti­ty of this data from the past is not suf­fi­ci­ent – a dilem­ma when it comes to making infor­med invest­ment and plan­ning decisions.

This is why, a mode­ling tool cal­led SUPRA tool (Simu­la­ti­on of Water Resour­ces Under Pre­sent and Future Cli­ma­te) is cur­r­ent­ly being deve­lo­ped and tes­ted in clo­se coope­ra­ti­on with the long-term rese­arch and deve­lo­p­ment part­ners alpS GmbH and alpS Rese­arch of the Uni­ver­si­ty of Inns­bruck. In the future, this tool will make it pos­si­ble to cal­cu­la­te the cur­rent water balan­ce situa­ti­on and future sce­n­a­ri­os more accu­rate­ly, espe­cial­ly in moun­tain­ous regi­ons with limi­ted data avai­la­bi­li­ty but also in all other are­as around the world.


ILF is member of the Bavarian Hydrogen Alliance


Hydro­gen is regar­ded as one of the key ele­ments for glo­bal ener­gy sys­tem trans­for­ma­ti­on and cli­ma­te pro­tec­tion, as it can be pro­du­ced and used fle­xi­b­ly and without emis­si­ons, and at the same time is easy to trans­port and store.

To streng­t­hen and fur­ther deve­lop Bavaria’s tech­no­lo­gi­cal com­pe­tence in the field of inno­va­ti­ve hydro­gen tech­no­lo­gies, the Sta­te of Bava­ria foun­ded the Cen­ter Hydrogen.Bavaria (H2.B) in 2019 and initia­ted the Hydro­gen Alli­an­ce Bava­ria. The aim is to bring tog­e­ther key play­ers in indus­try, sci­ence, and poli­tics in order, among other things, to advan­ce the topic of “hydro­gen eco­no­my” in Bava­ria as quick­ly as pos­si­ble and to achie­ve the use of hydro­gen in broad prac­ti­cal app­li­ca­ti­on. The focus here is, abo­ve all, on demons­tra­ti­on and light­house projects.

ILF has many years of prac­ti­cal expe­ri­ence in con­sul­ting, plan­ning, and pro­ject manage­ment in the ener­gy and trans­port sec­tor. We are cur­r­ent­ly sup­por­ting several pilot pro­jects on hydro­gen pro­duc­tion, trans­port, and accep­t­ance. Also, ILF advi­ses com­pa­nies on the use of hydro­gen along the ent­i­re value chain, thus con­tri­bu­ting to the estab­lish­ment of a hydro­gen infrastructure.

We are the­re­fo­re deligh­ted to be able to con­tri­bu­te to the pro­gress of hydro­gen tech­no­lo­gies as an offi­cial mem­ber of the Bava­ri­an Hydro­gen Alli­an­ce sin­ce June 2020.

It’s all new – the Obervellach II hydropower plant


Tog­e­ther with part­ners, ILF Con­sul­ting Engi­neers was in char­ge of the site super­vi­si­on and con­tract manage­ment for the new con­struc­tion of the Ober­vel­lach II hydro­power plant as com­mis­sio­ned by ÖBB Infra­struk­tur AG. This hydro­power plant repla­ces the two exis­ting power plants – Las­sach (built in 1905) and Ober­vel­lach I (built in 1929) in Carinthia/Austria – they will be deco­m­mis­sio­ned and part­ly dismantled.

The plan­ned new hydro­power plant will pro­vi­de trac­tion power (16.7 Hz) and will have a capa­ci­ty of 38 MW and con­sist of three water inta­ke struc­tures, an approx. 3.9 km long headrace tun­nel and an approx. 0.6 km long sto­rage tun­nel with a sto­rage volu­me of some 60,000 m³. Fur­ther­mo­re, the over­all pro­ject inclu­des an approx. 1.5 km long pres­su­re pipe­line (d = 1.8m) and a power house with two machi­ne units and an approx. 2 km long pres­su­re pipe­line (d=0.7 m) inclu­ding a small hydro­power plant (50 Hz) as well as fur­ther facilities.


Kick-off for further design services for the Belchen Road Tunnel


The Bel­chen road tun­nel was ope­ned in 1970 and con­sists of two sepa­ra­te twin-lane tubes with uni­di­rec­tio­n­al traf­fic, each having a length of 3.2 km. In ear­ly 2021, with the so-cal­led reha­bi­li­ta­ti­on tun­nel going into ope­ra­ti­on, the Bel­chen tun­nel sys­tem will com­pri­se three twin-lane tun­nels. ILF Con­sul­ting Engi­neers is also invol­ved in the design and con­struc­tion of the reha­bi­li­ta­ti­on tunnel.

Exten­si­ve reha­bi­li­ta­ti­on works were alrea­dy car­ri­ed out on the exis­ting road tun­nel from 2001 to 2003. Howe­ver, the swel­ling rock (anhy­dri­te) is incre­a­singly lea­ving visi­ble traces. In order to ensu­re the safe­ty and capa­ci­ty of one of Switzerland’s busiest roads, the two exis­ting tun­nels at Bel­chen will be refur­bis­hed one after the other as part of the second rehabilitation.

The inten­ded mea­su­res inclu­de the repla­ce­ment of parts of the in-situ lining, back­fil­ling of cavi­ties that were detec­ted in the crown, design of uti­li­ty lines and fire-figh­t­ing sys­tem, and expansion/new con­struc­tion of cross pas­sa­ges. Water ingress in con­nec­tion with swel­ling anhy­dri­te are the gre­at chal­len­ges in the­se com­plex ground conditions.

Being part of the design con­sor­ti­um, ILF was tas­ked with deve­lo­ping and imple­men­ting the pro­ject up to com­mis­sio­ning by the Swiss Federal Roads Office (FEDRO). The pro­ject was laun­ched in June 2020 and is expec­ted to be con­clu­ded by mid-2032.

Ferngas receives the building permit for its gas pipeline


Accord­ing to the Federal Minis­try of Eco­no­mics, natu­ral gas, having a mar­ket share of around 44%, is the most important source of heat and ener­gy for pri­va­te house­holds in Ger­ma­ny. To con­ti­nue to meet the asso­cia­ted high demand for natu­ral gas, the net­work ope­ra­tor Fern­gas, which ope­ra­tes a trans­mis­si­on and dis­tri­bu­ti­on net­work in Bava­ria, Thu­rin­gia and parts of Hes­se, Sax­o­ny and Sax­o­ny-Anhalt, is renewing one of its exis­ting natu­ral gas pipe­lines in Sax­o­ny and Thuringia.

The 125 km long pipe­line, which runs through Sax­o­ny and Eas­tern Thu­rin­gia, was built in the 1950s and 60s and is to be com­ple­te­ly rene­wed by 2023. The moder­niz­a­ti­on is plan­ned to take place in several sec­tions, without any dis­rup­ti­on being cau­sed to the sup­ply of gas along the exis­ting pipe­line rou­te. In addi­ti­on to the main lines and con­nec­ting lines, nume­rous ancil­la­ry faci­li­ties and rou­te-rela­ted infra­st­ruc­tu­re are being rene­wed. The new pipe­line will lar­ge­ly remain in the exis­ting pipe­line rou­te, which will mini­mi­ze the impact on both the envi­ron­ment and local residents.

The aim is to incre­a­se the ope­ra­tio­nal fle­xi­bi­li­ty of the net­work, as well as the capa­ci­ty and the secu­ri­ty of sup­ply for the com­ing deca­des. Fur­ther­mo­re, the rene­wal of the pipe­line will help impro­ve­ments to be made to pipe­line moni­to­ring and control.

ILF Con­sul­ting Engi­neers has been com­mis­sio­ned by Fern­gas to pro­vi­de pro­ject con­trol and pro­ject manage­ment ser­vices in accordance with the scope of ser­vices lis­ted in the AHO (Com­mit­tee of the Asso­cia­ti­ons and Cham­bers of Engi­neers and Archi­tects for the Fee Struc­tu­re) book­let no. 9.

Having near­ly com­ple­ted the rene­wal of the pipe­line in Sax­o­ny, the sta­tu­to­ry aut­ho­ri­ty appro­val and thus the buil­ding per­mit has now been recei­ved for the Thu­rin­gi­an sec­tion of the pipe­line, enab­ling Fern­gas to reach ano­t­her decisi­ve mile­stone in the rene­wal of its gas pipe­line in Thuringia.


8‑Lane Upgrade of the A 99 Munich Motorway Ring


The A 99 is one of the busiest motor­ways in Ger­ma­ny – up to 160,000 vehi­cles use the eas­tern bypass near Munich every day and traf­fic jams are a dai­ly occur­rence. To impro­ve the situa­ti­on, an 8‑lane upgrade of the motor­way is being desi­gned and has been under con­struc­tion for several years. In March 2020, ILF Con­sul­ting Engi­neers was com­mis­sio­ned by the Auto­bahn­di­rek­ti­on Süd­bay­ern to pro­vi­de design ser­vices for the upgrade of the A 99 bet­ween the Kirch­heim and Haar junctions.

The approx. 8 km long 8‑lane upgrade of the A 99 and approx. 4 km long upgrade of the A 94 also inclu­de the con­ver­si­on of the Mün­chen-Ost motor­way junc­tion into a modi­fied wind­mill with two semi-direct ramps. Addi­tio­nal­ly, the Feld­kir­chen-Ost, Pars­dorf and Haar junc­tions are to be adap­ted. The com­plex con­ver­si­on and upgrade is being car­ri­ed out without inter­rup­t­ing traffic.

ILF Con­sul­ting Engi­neers is respon­si­ble for the fol­lowing are­as: road design, struc­tu­ral design of civil engi­nee­ring struc­tures (noi­se bar­ri­ers and sup­por­ting struc­tures) and pro­ject manage­ment, as well as various sup­ple­men­ta­ry design ser­vices such as com­pre­hen­si­ve con­struc­tion pha­se and traf­fic manage­ment plan­ning and coor­di­na­te trans­for­ma­ti­ons of basic data.


ILF awarded with further planning services for SuedLink


As one of eight com­pa­nies nati­on­wi­de, ILF Con­sul­ting Engi­neers has qua­li­fied for a frame­work con­tract for various plan­ning ser­vices for the Sued­Link pro­ject in Ger­ma­ny. The focus of this frame­work con­tract with Ten­neT & Trans­net is on the regio­nal plan­ning offices. The frame­work agree­ments are divi­ded into the sec­tions North, Cen­tral, and South with cor­re­spon­ding sub-sec­tions. With a total length of appro­xi­mate­ly 680 km, Sued­Link thus con­sists of a total of 9 plan­ning sections.

Through the frame­work agree­ment, ILF Con­sul­ting Engi­neers has now been appoin­ted as „Regio­nal Plan­ning Bureau (RPB)” for the nort­hern­most sec­tion (PA1). With con­nec­tions to the grid con­nec­tion points Wils­ter and Bruns­büt­tel, it con­sists of one of the most tech­ni­cal­ly chal­len­ging sec­tions with a total length of approx. 71 km. The sub-sec­tion for pro­ject 3 extends from the Bruns­büt­tel to Sta­de grid con­nec­tion point, and the sub-sec­tion for pro­ject 4 extends from the Wils­ter to Sta­de grid con­nec­tion point.

ILF was initi­al­ly com­mis­sio­ned with the detail­ed design, inclu­ding pro­ject manage­ment and con­trol, the mobi­li­sa­ti­on pha­se, the rou­te inves­ti­ga­ti­on, the soil inves­ti­ga­ti­on, the coor­di­na­ti­on of the cros­sings as well as the plan­ning appro­val of the Elbe cros­sing. Com­mis­sio­ning is plan­ned for 2026.

Construction of new teaching & office building for Uni Innsbruck


Des­pi­te the cur­rent excep­tio­nal situa­ti­on, it was pos­si­ble to start con­struc­tion of the new tea­ching and office buil­ding I52A at the Uni­ver­si­ty of Inns­bruck (Aus­tria) in com­pli­an­ce with strict safe­ty and health requi­re­ments. The new buil­ding will be adja­cent to the his­to­ri­cal main buil­ding of the uni­ver­si­ty and will be cha­rac­te­ri­zed by its future-ori­en­ted design. By opti­mi­zing the pro­ject with regard to the limi­ted urban space avail­ab­le, a valu­able urban recrea­ti­on space will addi­tio­nal­ly be created.

The design of the nine-sto­ry buil­ding with a floor space of approx. 12,800 m² and a gross buil­ding volu­me of approx. 110,000 m³ fol­lows the princi­ples of sus­taina­bi­li­ty. This is con­sist­ent­ly reflec­ted in the design of the buil­ding ser­vices, wher­eby the Client’s low-tech con­cept is ful­ly accom­mo­da­ted for and is expres­sed in results opti­mi­zed from a cli­ma­te and eco­no­my perspective.

On behalf of the BUNDESIMMOBILIENGESELLSCHAFT M.B.H., ILF Con­sul­ting Engi­neers tog­e­ther with a part­ner has accom­pa­nied the deve­lo­p­ment of this extra­or­di­na­ry pro­ject in the capa­ci­ty of pro­ject con­trol­ler from the con­cep­tu­al design pha­se and will mana­ge the con­struc­tion tog­e­ther with the cli­ent to meet the qua­li­ty, time and cost criteria.

This mile­stone has not just been reached due to the work and efforts of all par­ties invol­ved in the pro­ject, but is also the result of the opti­mal com­bi­na­ti­on of engi­nee­ring excel­lence and pro­ject management!


White paper “Digitalization in Industry – An Austrian Perspective


The coope­ra­ti­ve doc­to­ral school SIC! (Smart Indus­tri­al Con­cept), which ILF is a coope­ra­ti­on part­ner of, has pro­du­ced a white paper tit­led “Digi­ta­liz­a­ti­on in Indus­try – An Aus­tri­an Per­spec­ti­ve“ on behalf of the Kli­ma- und Ener­gie­fonds (Aus­tri­an Cli­ma­te and Ener­gy Funds) as part of the natio­nal pro­ject Annex XVIII. The aim of this paper is to exami­ne the effects of digi­ta­liz­a­ti­on on the reduc­tion of green­house gas emis­si­ons in ener­gy inten­si­ve industries.

The eight par­ti­ci­pa­ting PhD stu­dents, one of whom is ILF employee Leo­pold Prendl, are inves­ti­ga­ting 15 rele­vant tech­ni­ques, tech­no­lo­gies and app­li­ca­ti­ons, as well as the cur­rent situa­ti­on in Aus­tria. They also show that digi­ta­liz­a­ti­on mea­su­res are both eco­no­mi­c­al and sustainable.

TBM breakthrough in Georgia


With the sup­port of ILF Con­sul­ting Engi­neers, assuming the role of Owner’s Engi­neer, the Mtkva­ri Hydro Power Pro­ject in Geor­gia, which is mana­ged by Mtkva­ri Hesi LLC and finan­ced by the Geor­gi­an Co-Invest­ment Fund, has reached one of the most important pro­ject milestones.

On Febru­a­ry 6th, 2020, the bre­akthrough of the lon­gest and widest tun­nel in Geor­gia to date has been com­ple­ted. Exca­va­ti­on of the 9.6‑km-long and 6‑m-wide tun­nel was achie­ved using a Hard Rock Dou­ble Shield TBM.

The total design capa­ci­ty of the Mtkva­ri HPP is 53.0 MW and its expec­ted annu­al ener­gy genera­ti­on is 251.5 GWh, which equa­tes 1.9 % of Georgia’s total electri­ci­ty con­sump­ti­on. The tun­nel exca­va­ti­on con­sti­tu­tes a major achie­ve­ment wit­hin the con­struc­tion pro­cess and its com­ple­ti­on will allow the final sta­ge of the HPP con­struc­tion to commence.


Lighthouse Solar Program in Senegal now in operation


In 2015 ILF Con­sul­ting Engi­neers was awar­ded an Owner’s Engi­neer con­tract by Senelec and KfW for the imple­men­ta­ti­on of eight pho­to­vol­taic and hybrid power plants in Sene­gal. Now, only four years after the start of the pro­ject, the­se first of its kind pro­jects in Sene­gal and West Afri­ca are in ope­ra­ti­on; the last power plants will be com­mis­sio­ned ear­ly 2020.

The­se PV and hybrid power plants are some of the lar­gest in West Afri­ca and are light­house pro­jects for the dis­tri­bu­ti­on of the­se tech­no­lo­gies in Afri­ca. The aim was to redu­ce Senegal’s depen­den­cy on light fuel/heavy fuel oil imports, redu­ce the cost of electri­ci­ty as well as to impro­ve the qua­li­ty and the relia­bi­li­ty of the electri­ci­ty sup­ply in Senegal.
Fur­ther­mo­re, the elec­tri­fi­ca­ti­on of rural are­as and the social & eco­no­mic deve­lo­p­ment of the­se regi­ons should be pro­mo­ted. With eight power plants being loca­ted all over the coun­try, seven remo­te cities with a popu­la­ti­on of up to 50,000 inha­bi­tants each can now be sup­plied with gree­ner ener­gy 24/7. The pro­ject con­sists of one grid-con­nec­ted 23MWp PV power plant (sup­ply­ing among others the inter­na­tio­nal air­port of Sene­gal), four PV/­Li-ion battery/diesel hybrid sys­tems and three PV/diesel hybrid systems.

As part of ILF’s role as OE, ILF was respon­si­ble for the con­cep­tu­al design, ten­de­ring, con­struc­tion super­vi­si­on and com­mis­sio­ning as well as for super­vi­sing the plants’ per­for­mance and the O&M Con­trac­tor during the first year.

Challenges at the “Wolframstrasse” S‑Bahn Tunnel – Stuttgart 21


In 2017, ILF Con­sul­ting Engi­neers was awar­ded a con­tract for the detail­ed design ser­vices of Sec­tion 1.5 – Per­mit App­li­ca­ti­on Pro­ce­du­re (con­tract sec­tion 4 South), bet­ter known as “Wolf­ram­stras­se”, by a joint ven­ture con­sis­ting of the com­pa­nies Kunz, Leon­hard Weiss and Kurt Motz. This chal­len­ging sec­tion is an inte­gral part of the lar­ge-sca­le pro­ject “Stutt­gart 21”. It is an approx. 450 m long rapid tran­sit rail­way tun­nel, pre­do­mi­nant­ly con­struc­ted using the cut-and-cover method, which con­sti­tu­tes the S‑Bahn link from the North to the cen­tral station.

It is worth men­tio­ning that about 100 m are to be con­struc­ted in an exis­ting tun­nel while kee­ping the rail­way ope­ra­tio­nal. Throughout the ent­i­re con­struc­tion peri­od, two of the four rail tracks will be kept in ope­ra­ti­on. Addi­tio­nal chal­len­ges ari­se from the loca­ti­on of the con­tract sec­tion in the immedia­te vicini­ty of the rail­way sta­ti­on, from avoiding inter­rup­ti­ons of traf­fic in Wolf­ram­stras­se, from con­struc­tion works car­ri­ed out in exis­ting struc­tures and from the low over­bur­den of a sewer main that cros­ses the tun­nel. To date all chal­len­ges have been tack­led and the design ser­vices are taking place in accordance with the spe­ci­fi­ca­ti­ons of the joint venture.

After the com­ple­ti­on of the con­struc­tion works at Stutt­gart 21, the ent­i­re plat­form area, the track area and the exis­ting tun­nel will be remo­ved to make room for a new city district.


ILF awarded mainline FEED & Detailed Engineering for KAPS


Key­e­ra Corp. (Cal­ga­ry, Alber­ta, Cana­da) recent­ly awar­ded ILF Con­sul­ting Engi­neers the main­li­ne FEED & Detail­ed Engi­nee­ring con­tract for the esti­ma­ted CAD 1.3 bil­li­on KAPS project.

KAPS is a natu­ral gas liquids (NGL) and con­den­sa­te pipe­line sys­tem that will trans­port gro­wing pro­duc­tion from the Mont­ney and Duver­nay fiel­ds, in nor­thwes­tern Alber­ta, to Fort Sas­kat­che­wan, north of Alberta’s capi­tal city Edmon­ton. Key­e­ra has part­ne­red with Sem­CAMS Mid­stream ULC, owned joint­ly by Sem­Group Cor­po­ra­ti­on® and KKR, to deve­lop this pipe­line system.

Based on the cur­rent scope, KAPS will con­sist of a 16-inch con­den­sa­te pipe­line and a 12-inch NGL mix pipe­line, asso­cia­ted pum­ping sta­ti­ons, inclu­ding pro­vi­si­ons for future expan­si­on. The total main­li­ne length per cur­rent scope is fore­se­en to be appro­xi­mate­ly 550 km. KAPS will initi­al­ly be con­struc­ted from nor­thwest of Gran­de Prai­rie and con­nect to Key­er­a’s Fort Sas­kat­che­wan Frac­tio­n­a­ti­on and Sto­rage Faci­li­ty (KFS).

Power Generation using Pipelines


ILF Con­sul­ting Engi­neers was com­mis­sio­ned by a well-known cli­ent to inves­ti­ga­te the instal­la­ti­on of a tur­bi­ne for ener­gy reco­very in a poten­ti­al cru­de oil pipe­line sys­tem. Not only did this inves­ti­ga­ti­on have to make sure that the ener­gy reco­very sys­tem would not have a nega­ti­ve impact on the con­vey­an­ce of oil, but also take account of the fact that pipe­lines are nor­mal­ly ope­ra­ted using dif­fe­rent flow rates under chan­ging pres­su­re conditions.

Turning on the water at Hochalm II storage reservoir


The Hin­ter­glem­mer Berg­bah­nen have been able to start fil­ling the expan­ded Hoch­alm II sto­rage reser­voir (Aus­tria) on time – a moder­niz­a­ti­on which has taken two years. The water reser­voir for the snow­ma­king sys­tem of the Hoch­alm area was expan­ded in two con­struc­tion sta­ges. Works began on 4 June 2018, and water star­ted flowing into the Hoch­alm II sto­rage reser­voir on 30 August 2019. Fil­ling of the sto­rage reser­voir, which can hold 251,300 m³ of water, began on schedule.

By deli­vering inno­va­ti­ve design and a cle­ver con­struc­tion sequence, ILF Con­sul­ting Engi­neers has been assis­ting its long-stan­ding cli­ent with the expan­si­on and streng­t­he­ning of the Hoch­alm snow-making sys­tem sin­ce 2016. “The clo­se coope­ra­ti­on with the Hin­ter­glem­mer Berg­bah­nen enab­led our team to deli­ver an inno­va­ti­ve pro­ject to secu­re snow con­di­ti­ons in Hin­ter­glemm for future ski sea­sons,” says Ger­hard Pum­per­nik, Head of the Depart­ment of Ski Resorts and Alpi­ne Engi­nee­ring at ILF.

For ten years now, ILF Con­sul­ting Engi­neers has been sup­por­ting SOS-Kin­der­dorf (SOS Children’s Vil­la­ges) to give child­ren and young peop­le a loving home.

“The coope­ra­ti­on with SOS-Kin­der­dorf is some­thing which is very clo­se to our hearts, becau­se after all, child­ren are our pre­sent and our future. We are deligh­ted if ILF can help sup­port child­ren, young peop­le and their fami­lies, who find them­sel­ves in dif­fi­cult situa­tions, and if our dona­ti­ons can help them find their way out of cri­ses”, Josef Mayr, one of the mana­ging direc­tors at ILF Con­sul­ting Engi­neers Aus­tria GmbH. It is our heart­felt wish at ILF to con­ti­nue this part­ners­hip in the com­ing years, and thus achie­ve posi­ti­ve things together.

“Thanks to the sup­port of pri­va­te donors and com­pa­nies, over the last 70 years we have been able to come a step clo­ser to achie­ving our goal. I would the­re­fo­re like to sin­ce­rely thank ILF for their con­tri­bu­ti­on”, Manue­la Mader, SOS-Kinderdorf.

Even after 70 years, SOS-Kin­der­dorf still has one over-arching goal: “To give every child a loving home” – be that in the care of alter­na­ti­ve fami­lies or by sup­por­ting fami­lies in need. In total, SOS-Kin­der­dorf in Aus­tria pro­vi­des a new home for around 1,800 child­ren and young peop­le, and sup­ports more than 4,700 child­ren and their families.


ILF ventures into Uganda’s water infrastructure market


The Natio­nal Water & Sewerage Cor­po­ra­ti­on (NWSC) com­mis­sio­ned ILF Con­sul­ting Engi­neers and its inter­na­tio­nal part­ner for the “Kage­ra Water Works” pro­ject in Ugan­da. Being the first and lar­gest of many packa­ges which will make up the umbrel­la pro­ject “Deve­lo­p­ment of Water and Sani­ta­ti­on Infra­st­ruc­tu­re for the Mbara­ra & Masa­ka Are­as”, this pro­ject will be finan­ced by the French Agen­cy for Deve­lo­p­ment (AFD).

The over­all objec­ti­ve of the pro­ject is to secu­re and impro­ve the sup­ply of drin­king water as well as the sani­ta­ti­on infra­st­ruc­tu­re in Mbara­ra, Masa­ka and their sur­roun­dings. Packa­ge 1 com­pri­ses the deve­lo­p­ment of the Kage­ra water sup­ply sys­tem, which inclu­des an inta­ke from the Kage­ra River – Upper White Nile – (capa­ci­ty: 8m³/s), the Kage­ra drin­king water tre­at­ment plant (first pha­se capa­ci­ty: 18,000 m³/d) and the main 58-km-long trans­mis­si­on pipe to Mbarara.

Connecting Austria and Switzerland


ILF Con­sul­ting Engi­neers have been appoin­ted by ASFINAG BMG, in a joint ven­ture, to car­ry out the tun­nel design for the S18 Lake Con­stance express­way as part of the preli­mi­na­ry design (rou­te selec­tion pro­cess). The S18 is a major link road bet­ween the A1 motor­way (Switz­er­land) and the A14 Rheintal/Walgau motor­way (Aus­tria).

The area under inves­ti­ga­ti­on encom­pas­ses the con­nec­tion to the Swiss road net­work (A13/A1) near St. Magrethen/Höchst, whe­re the cros­sing of the Rhi­ne, the Lus­ten­au canal and the ÖBB rail­way line is plan­ned. Two new junc­tions are also being considered.

The pro­ject area is of gre­at impor­t­ance in view of sett­le­ment area, agri­cul­tu­ral use, recrea­tio­nal use and ground­wa­ter uti­liz­a­ti­on. Some of the con­ser­va­ti­on are­as as well as the are­as pro­tec­ted under the EU’s Flo­ra-Fau­na-Habi­tat Direc­ti­ve, which are found wit­hin the pro­ject area, also have a signi­fi­cant influ­ence. The geo­lo­gy along the appro­xi­mate­ly 7 km long sec­tion is cha­rac­te­ri­zed by the flu­vi­al sedi­ments from the Rhi­ne and lacus­tri­ne depo­sits, and the­re­fo­re poses a par­ti­cu­lar chal­len­ge for the tun­nel design.


Basic Design for the Somogy Field Development


On behalf of ADNOC Refi­ning, ILF Con­sul­ting Engi­neers has recent­ly com­ple­ted the basic design for the Somo­gy Field Deve­lo­p­ment in Hungary.

The aim of this pro­ject was to pro­vi­de all the necessa­ry engi­nee­ring and pro­ject manage­ment (cost, sche­du­le and risk assess­ment) ser­vices nee­ded for the veri­fi­ca­ti­on of the exis­ting gas/condensate gathe­ring sys­tem and its upgrade, name­ly the con­nec­tion of 4 gas wells to the exis­ting trunkline.

The upgrade of the exis­ting Babóc­sa Gas Plant, invol­ving the instal­la­ti­on of the requi­red gas tre­at­ment units, was also inclu­ded in the scope of services.


ILF’s involvement in four-track upgrade of Western railway line


ILF Con­sul­ting Engi­neers was recent­ly com­mis­sio­ned by ÖBB Infra­struk­tur AG to pro­vi­de plan­ning and design input for the four-track upgrade of the wes­tern rail­way line for the Linz-March­trenk and March­trenk-Wels sections.

The upgrade of the­se sec­tions makes it pos­si­ble to incre­a­se the line capa­ci­ty and is an important step in the four-track upgrade of the rail­way line bet­ween Vien­na and Wels that forms part of the trans-Euro­pean net­work for rail and inter­mo­dal transport.

The pro­ject is imple­men­ted step by step and star­ted with the works for the sec­tion “Linz Main Sta­ti­on west site” in the autumn of 2018. The per­mit­ting pro­ces­ses for Linz–Marchtrenk (length approx. 15.7 km) and Marchtrenk–Wels (length approx. 6.4 km) are cur­r­ent­ly under­way. Maxi­mum speeds of up to 230 km/h shall be pos­si­ble in both line sec­tions. A speed of up to 160 km/h is plan­ned for regio­nal rail transport.

ILF has been ent­rus­ted with exe­cu­ting the detail­ed design in the plan­ning pha­se of the pro­ject imple­men­ta­ti­on of both sections.

B.Robots – ILF supports future changemakers


The B.Robots Team of the “Höhe­re tech­ni­sche Bun­des­lehr- und Ver­suchs­an­stalt Graz-Gös­ting” (Aus­tria) lan­ded the vice world cham­pion tit­le in the robo­tics com­pe­ti­ti­on of the First Lego League (FLL) World Fes­ti­val, held in Detroit from April 25th to 29th, 2019, by intro­du­cing its smart “dPro Bot­t­le”. So far, no other Aus­tri­an team has suc­cee­ded in win­ning this title.

In addi­ti­on, B.Robots took fifth place in the Robot Game in a field of 104 teams. This year more than 35,000 teams from around the word ent­e­red the FLL competition.

ILF congra­tu­la­tes the pro­ject team on this remar­kab­le achie­ve­ment and is proud of having been able to make a small con­tri­bu­ti­on to this success.


The environment loves rail travelers


To make the public more awa­re of the con­tri­bu­ti­on tra­ve­ling by rail makes to pro­tec­ting our envi­ron­ment and redu­cing our car­bon foot­print, the Aus­tri­an Federal Rail­ways (ÖBB) laun­ched the Green Points initia­ti­ve over two years ago.

As part of this initia­ti­ve, peop­le who use the ÖBB for busi­ness trips can collect green points, which are used to sup­port spe­ci­fic envi­ron­men­tal pro­jects. By using the train for busi­ness trips, employees from ILF in Aus­tria have cut down their CO2 emis­si­ons by 63.1 tons in the last year, being once again amongst some of the most fre­quent rail tra­velers in Aus­tria. Com­pa­red to the pre­vious year, this is a 17.5% incre­a­se in the num­ber of train journeys.

ILF high­ly appre­cia­tes this ÖBB initia­ti­ve, as the sus­tainab­le pro­tec­tion of the envi­ron­ment is of utmost impor­t­ance to our com­pa­ny both when designing struc­tures and faci­li­ties and when per­forming day-to-day pro­ject work. We stri­ve to con­ti­nue making a valu­able con­tri­bu­ti­on to ensu­ring sus­taina­bi­li­ty in Aus­tria by using ÖBB trains for busi­ness trips in years to come.

ILF contributes to VBI Guide to Renewable Energy


During the 2019 Ber­lin Ener­gy Tran­si­ti­on Dia­lo­gue, which was hos­ted and sup­por­ted by the Ger­man Federal Government, the Ger­man Asso­cia­ti­on of Con­sul­ting Engi­neers (VBI) publis­hed its Gui­de to Rene­wa­ble Ener­gy with various con­tri­bu­ti­ons from ILF Con­sul­ting Engineers.

The Gui­de to Rene­wa­ble Ener­gy shall pro­vi­de poli­cy­ma­kers, admi­nis­tra­tors and engi­neers with les­sons from the Ger­man expe­ri­ence of the ener­gy tran­si­ti­on and shows a broad ran­ge of tech­no­lo­gies that are sui­ta­ble and vital for an ener­gy tran­si­ti­on. ILF is proud to have con­tri­bu­t­ed to this important and semi­nal hand­book with its expe­ri­ence in are­as such as pro­ject set­up & imple­men­ta­ti­on, rou­ting, bank­a­ble fea­si­bi­li­ty stu­dies, hydroelectric power, gas net­works, ener­gy & gas sto­rage as well as power transmission.

ILF engaged at Basra Water Supply Project


On April 25, 2019 The Minis­try of Con­struc­tion, Housing, Muni­ci­pa­li­ties and Public Works of Iraq awar­ded ILF with the Pro­ject Deve­lo­p­ment, Engi­nee­ring and Site Super­vi­si­on Ser­vices for the water sup­ply pro­ject in the Bas­ra Governorate.

The pro­ject inclu­des a Sea­wa­ter Rever­se Osmo­sis Desa­li­na­ti­on Faci­li­ty, the Water Trans­mis­si­on Sys­tem to sup­ply 11 cities inclu­ding Bas­ra City with addi­tio­nal drin­king water and a power plant to pro­vi­de the requi­red electri­ci­ty to ope­ra­te the system.

The pro­ject is envi­sa­ged to be exe­cu­t­ed based on ILF’s pro­po­sed concept:

  • 1,000,000 m³/day Sea­wa­ter Rever­se Osmo­sis Desa­li­na­ti­on Faci­li­ty loca­ted at the Ara­bi­an Gulf in Fao;
  • Appro­xi­mate­ly 270 km of Water Trans­mis­si­on Pipe­lines for the dis­tri­bu­ti­on of the desa­li­na­ted water to the cities of the Bas­ra Governorate;
  • A Gas fired Power Plant to pro­du­ce the requi­red power for the Desa­li­na­ti­on Plant and Pum­ping Stations.

The pro­ject will be the first step of Iraq’s new water stra­te­gy and shall deli­ver addi­tio­nal drin­king water wit­hin 4 years.

ILF awarded with contract for the next phase of the SuedLink


ILF Con­sul­ting Engi­neers, which acts as the lea­der of the con­sor­ti­um ArgeSL 2019, and has alrea­dy been invol­ved in various sta­ges of the Sued­Link pro­ject, has now also been awar­ded the con­tract for the next pha­se of the Sued­Link pro­ject, by Ten­neT and Trans­netBW (Ger­ma­ny). Over the next 20 mon­ths, ArgeSL 2019, con­sis­ting of ILF and its part­ners Fro­elich & Spor­beck, as well as GfN, will be per­forming the ser­vices invol­ved in the pro­ject pha­ses §19+§20 NABEG, which invol­ve, amongst others, the app­li­ca­ti­ons for plan­ning appro­val, inclu­ding rough rou­ting, the tech­ni­cal plan­ning as well as pro­ject manage­ment and envi­ron­men­tal planning.

The Sued­Link shall trans­port ener­gy gene­ra­ted in wind parks in nort­hern Ger­ma­ny to sou­thern Ger­ma­ny, ther­eby ser­ving major con­su­mers in sou­thern Ger­ma­ny via a HVDC under­ground cable. The Sued­Link con­sists of two point-to-point con­nec­tions, which will each have a trans­mis­si­on capa­ci­ty of 2 giga­watts (GW), i.e. a total capa­ci­ty of 4 GW. This capa­ci­ty, which is rough­ly equi­va­lent to the capa­ci­ty of four nuclear power plants, will sup­ply around 10 mil­li­on house­holds with electri­ci­ty. As Ger­many’s lar­gest infra­st­ruc­tu­re pro­ject to date, the Sued­Link pro­ject sets new inter­na­tio­nal stan­dards, being the first pro­ject of its kind in the field of under­ground cables.
