Construction Progress July 2021


The company building is now almost finished, last remaining works are in progress. The empty pipe route is also almost completed in the relevant area, the handover of the pipe clearances is still pending. The paving work around the building is the last step that will be visible from the outside. A lot has also happened inside: The company Elpro Berlin has already placed the racks in the building, including the HESOP of the company Alstom and also the charging technology of the company M&P. Things will get exciting in mid-August: the first charging mast for this line endpoint will be erected at night (manufactured by the company Masche Metallbau).

The remaining work on the GUW+ building will be completed in the next few days. Inside, the raised floor has already been installed, transformer rails have been mounted in the transformer chambers, and the vinyl has been laid on the reinforced concrete floor in the battery rooms. The equipment with the ventilation technology is also well advanced. As shown in the photo, civil engineering work is still outstanding in the area of the parking lot. Among other things, the last meters of the empty pipe route must be laid to the GUW+. The company Elpro is also already on the construction site and will place the two transformers in the building in week 23.

On March 26th, 2021, the shell of the over 300 m² company building was completed. More than 30 trucks delivered the precast concrete elements over the course of five nights, which were set up during the day. What follows now is work on the interior of the building, the roof and the facade, which is expected to be completed on May 17, 2021.

By 2023, ÜSTRA aims to have 48 electric buses running completely on electric power on all inner-city lines within Hanover's environmental zone. An ambitious goal - CEO Dr. Volkhardt Klöppner, Denise Hain, Director of Operations and Human Resources, and Elke Maria van Zadel, Director of Technology, IT and Infrastructure, explain in the video how this can work. Part of this is our GUW+, which is presented from minute 04:39.
