Renewal/Extension of the District Heating, Water and Electricity Systems in Weyermannshaus Ost (Berne, Switzerland)

The construction of the new Bern-Forsthaus West waste incineration plant at a new location made it necessary to align the main connector routes to the existing district heating distribution network. The project included the renewal of the old district heating system as well as the connection of new residential and commercial buildings to the district heating network. Furthermore, the water and electricity systems were replaced and parts of the road Murtenstrasse were rehabilitated including road drainage by the municipal civil engineering authority.
