Leading consulting group with a 360° approach
COWI prepared the detailed design of all permanent structures for Copenhagen's new district heating tunnel. We also prepared the tender documents for the tunnel and shaft installations and provided assistance to the client, KE Varme A/S, regarding their in-house design of the pipes.
COWI was in charge of supervising the works as well as of the technical follow-up and assistance to the client regarding environmental issues, authority contacts, etc.The new, more fuel-flexible facility is estimated to give an annual saving of around DKK 50 million.
From the very start it was the plan to carry out the project under a partnering agreement, where the contractor's alternatives, good ideas, etc. would be discussed in the negotiation phase and, if agreed, taken on board.The KFT JV - a joint venture formed by the Danish contractor MTH A/S and the German contractor Hochtief AG - was appointed to construct the tunnel and shafts. The KFT JV joined KE Varme and COWI in a partnership group. In early 2007, the pipe contractor, KLR Entreprise, was appointed. KLR is a joint venture formed by Kemp & Lauritzen and L&H Rørbyg.
The first stretch of the tunnel from Amagerværket to Adelgade started to operate in early 2009. The second stretch followed in the autumn of 2009. The total cost of the project is expected to be DKK 750 million (2004 prices), of which the tunnel shaft contract and the design and estimated unforeseen costs cover two thirds.
