Implenia wins building construction contracts worth more than CHF 170 million in Germany and Switzerland
Total contractor contract for planning and new construction of the rehearsal and workshop centre of the Bavarian State Theatre in Munich | Partnership-based project management with integrated range of services | Two new replacement buildings for apartment blocks | Focus on sustainability | Contract volume totalling over CHF 170 million.
Implenia has been commissioned by the Bavarian State Ministry of Science and the Arts to act as total contractor for the planning and construction of a new rehearsal and workshop centre (PWZ) for the Bavarian State Theatre in Munich, ready for operation. After the Regensburg Initial Reception Centre and the Regensburg State Housing Estate, this is already the third project Implenia has realised as a total contractor for the Free State of Bavaria as client, represented by the Regensburg State Building Authority. Planning began in March and construction is due to start in June. Handover to the client is scheduled for December 2026. The order volume for Implenia is more than EUR 140 million.
The agreed services include the planning and construction of the PWZ, from the excavation pit for the 93-metre-long and 86-metre-wide L-shaped building to the interior design, including building services, materials handling technology and stage technology for three rehearsal stages, as well as workshop equipment and canteen facilities. The contract also includes the design of the outdoor facilities, including a depot with access zones, delivery and parking areas for lorries and containers, an underground car park and the landscaped outdoor area.
The technically demanding project includes the creation of large, freely spanned spaces for the rehearsal stages, which, as a steel composite construction, are reminiscent of bridge construction. An acoustically highly effective building partition will protect the rehearsal wing from noise and vibrations from the workshop wing. Other special soundproofing devices will allow the rehearsal stages to be used in parallel. Implenia was able to win the best planners for the special trades of stage technology and workshop technology.
Partnership and integrated approach impressed even at the bidding stage
Implenia impressed even at the bidding stage with its partnership approach and a team of highly qualified internal and external specialists who offered solutions to the complex technical requirements of the project. In the implementation phase, Implenia will manage the team and, together with its own specialist planners, realise the input and implementation planning as well as the new building ready for operation.
As an integrated construction and real estate service provider, Implenia will provide a large proportion of the services itself across all divisions: The foundation engineering division is responsible for the excavation pit. For the shell construction, specialist knowledge from the civil engineering division will be called upon. BCL Building Construction Logistics, a member of the Implenia Group, is responsible for the smooth, safe and sustainable organisation of the construction site. The Façade Technology division is contributing its expertise to the construction of the building envelope made of dark grey corrugated fibre panels, prefabricated concrete elements and aluminium window elements with external venetian blinds.
Digitalisation and tools to increase efficiency
A BIM model was set up for the new building, on which all planners are working. This means that the planning status is transparent at all times and can be flexibly adapted. The BIM model is also used in the execution, for example to coordinate the various trades. In addition, it is planned to use the model for construction process simulations, for quantity takeoff and for tendering the finishing trades. Lean construction methods and tools are used to optimise construction processes, to control material flows and to precisely coordinate the trades. This enables a continuous and even construction process.
High sustainability requirements
Sustainable new construction and operation are important to both the client and Implenia. Accordingly, the building is being constructed in accordance with the Building Energy Act (GEG § 10), all materials comply with the “low-pollutant construction” requirements catalogue (QN 3) of the Bavarian State Construction Directorate, and the technical systems are designed for sustainable and environmentally friendly operation.
Besenrainstrasse and Katzenbachstrasse Zurich – sustainable replacement housing
In Switzerland, Implenia was commissioned by client Swiss Life Asset Management AG as general contractor for the replacement housing “Besenrainstrasse/Morgentalstrasse” in Zurich Wollishofen. This is a project with 36 rental flats and 22 underground parking spaces, which will be built using the solid construction method. Construction work started in March with a pollutant clean-up, and handover is scheduled for the end of November 2024. SNBS Platinum certification is being sought for the new building.
Implenia was also awarded a contract by the SBB pension fund for a replacement building on Katzenbachstrasse in Zurich-Seebach. Implenia will also be the general contractor for this project. The new building will have 30 high-quality rental flats with a ventilated wooden façade on three floors and 18 underground parking spaces. Construction work has already started in February with a pollutant clean-up carried out by the master builder’s division. Completion is scheduled for February 2025. The flats will be built to the Minergie ECO standard.
Through these two contracts, Implenia is further contributing to the sustainable renewal of Switzerland’s real estate stock with its comprehensive expertise. The total value of both contracts is over CHF 30 million.
