Trasse West I – Construction of District Heating Pipelines Lot 3.1.2: Pipe Material & Insulation Supply & Construction Services Description: The contracting authority operates a heating plant at Frankfurter Straße 100 in Darmstadt. The heat is primarily generated by the nearby waste-to-energy plant (hereinafter "MHKW"), delivered to the heating plant and distributed from there.

To utilise this potential, new district heating pipelines will be constructed between the heating plant, the MHWK and further supply areas. The overall project will be divided into a construction section North (lot 3.1) and a construction section South (lot 3.2) for commercial, organisational and operational reasons. The deep and pipe construction works in the construction section North and in the construction section South will be tendered separately. The deliveries and associated services for the plastic casing pipe laying system (KMR) will be tendered together for both construction sections. The contractor (AN) will be commissioned with the pipe system delivery and the sleeve insulation for underground district heating pipelines.
