Uetliberg Tunnnel (CH): ILF helps Swissgrid turn up the voltage

more

Swissgrid has commis­sioned ILF, as part of the engineering consortium KiWa220 (@Suisseplan Bau, @Boess Gruppe), to plan and design the extension of the high-voltage line in the Zurich South area. In order to increase the security of electricity supply to the city of Zurich (CH) and the left side of Lake Zurich, the current line will be upgraded to 220 kilovolts (kV) and connected to the grid in the South.

In the first project section, the cable will be laid under­ground along the motorway. Subse­quently, the cable will be pulled through the conduit blocks already in place in both tubes of the Uetliberg Tunnel. In the third project section, a new 2‑km-long energy tunnel, with a diameter of approx. 4 m, will be driven using a tunnel boring machine.

The energy transition in Germany is gaining momentum

more

To transmit wind power from the windy North to the South, SuedLink, a high-voltage direct current (HVDC) trans­mission line consisting of multiple under­ground cables, is to be built in Germany.
The SuedLink is approx. 700 km long and will be imple­mented by the two project developers Trans­netBW GmbH and TenneT TSO GmbH, with two 2 GW connec­tions each starting in Schleswig-Holstein and running via Baden-Württemberg to Bavaria.

The project developer Trans­netBW GmbH has submitted the first permit appli­cation documents for the southernmost permit appli­cation section, E3, to the Federal Network Agency. ILF, as the regional engineering office, has assisted with the prepa­ration of these documents. The Federal Network Agency has already confirmed the comple­teness of the documents and the process of making the documents available for public review has been initiated.

What’s special about permit appli­cation section E3 is that this section of the trans­mission line runs through the Südwest­deutsche Salzwerke AG’s mines. The special structure in the mines will be connected via two new shafts, which will be almost 200 m deep. With the initiation of the final phase of the approval procedure, the founda­tions for an early start to construction of the SuedLink in the Heilbronn region have now been laid.

In the North, ILF, as the respon­sible regional engineering office, has also contri­buted to the permit appli­cation documents for permit appli­cation section A2 – the first northern section of the trans­mission line – being submitted to the Federal Network Agency in due time by the project developer TenneT TSO GmbH. The parti­cular challenge in this section was to integrate the requested alignment for the two under­ground cables into the design documents for the special structure ElbX, an approx. 5‑km-long tunnel structure between Schleswig-Holstein and Lower Saxony that runs under the River Elbe.

Microtunneling: Transit and retention collector in Warsaw (POL)

more

The Municipal Water and Sewerage Company commis­sioned ILF to prepare compre­hensive design documen­tation for the final stage of the construction of the Vistula collector In Warsaw.

This largest transit and retention collector in Poland’s capital is expected to mitigate the negative effects of climate change on the city. Besides trans­porting waste­water, the new infra­st­ructure facility will also temporarily store excess rainwater and therefore decrease the risk of flooding and reduce storm overflows into the Vistula river. The existing storm sewers as well as the sewer collectors to the Farysa facility and the pressure pipe from the Powiśle pumping station will be connected to the new collector. The collector, with a capacity of 50,000 m³ and base diameters from 1.2 m to 3.2 m, will be about 9.5 km long and will be constructed at a depth of 6 to 15 m below ground. For the construction of the collector, state-of-the-art trenchless micro­tun­neling technology will be applied.

“ILF’s task is to prepare compre­hensive design documen­tation for the third stage of construction of the Vistula collector – speci­fi­cally, from the connection chamber with the Bielański collector to the Farysa facility, along with the pumping station and the necessary̨ associated infra­st­ructure,” explains Marcin Przepiórka, Managing Director from ILF Poland.

The investment is part of a broader project co-financed by EU funds and imple­mented by the Municipal Water and Sewerage Company in Warsaw. Completion of the project documen­tation (construction design and detailed designs) is scheduled for late 2022.

EDCS: ILF develops concept for industrial energy supply system

more

As part of an energy research project, ILF has carried out a specific technical, economic and ecolo­gical evaluation of an innovative EDCSproof energy concept for Wiesbauer, an Austrian sausage producer. EDCSproof stands for “Energy Demand Control System – Process Optimiz­ation For indus­trial low-tempe­rature systems” and is a colla­bo­rative research project led by the Austrian Institute of Technology (AIT), funded by the Austrian Research Promotion Agency (FFG) and involving eight scien­tific and indus­trial partners.

The primary goal is to develop an online control concept for indus­trial energy supply systems. This concept shall support the integration of renewables through the use of energy storage, create “flexible consumers” for electric grids, increase efficiency through optimal control of the overall system, and utilize waste heat by using high-tempe­rature heat pumps (<150°C). Hence, it is a concept for decar­bo­niz­ation which recognizes the possi­bi­lities of digitalization.

The evaluation carried out by ILF included an investment calcu­lation based on possible instal­lation locations and the integration of the respective components in the power supply system taking into account the route of the existing piping, spatial condi­tions and other project parameters. ILF compared the EDCSproof energy concept with Wiesbauer’s existing energy concept (CO2 savings, reduction of primary energy factor, cost reduction, etc.) and detected an energy and production cost saving potential.

Update for one of the most spectacular airports

more

The Airports Authority of India (AAI) has appointed ILF to carry out a feasi­bility study for the develo­pment and upgradation of Agatti Airport.

This airport is the gateway to the Lakshadweep islands and is the only airport off the West Coast of India. The runway is to undergo a change in design and is to be extended to enable Airbus A320 operation. The terminal building, the apron, the runway end safety area (RESA) system and the taxiway are also to be upgraded for passenger flights. The upgradation of this airport is a challenge due to its special location, the required recla­mation of land and the non-availa­bility of local construction materials and labor.

Along with the feasi­bility study, ILF is also performing the surveying works and environ­mental studies for this project in which environment protection – e.g. marine and wildlife activities such as coral reef rehabi­li­tation – will play a key role.
