The contracting authority needs to ensure continuous access to standardised concrete products for daily maintenance, acute and planned improvements and new installations of the municipal road network in Trondheim. Attention is relating to the fact that the procurement is only for purchases of goods. The setting down and accompanying contract work will be carried out by the contracting authority itself. The concrete products shall primarily be used for: Operation, maintenance and replacement of sand trap manholes. Replacement and new establishment of concrete pipes in various dimensions. Traffic safety measures, including securing site areas, roads and places when using physical barrier material (concrete pig/jersey stone). The framework agreement shall be based on a combination of two delivery models: Delivery from tenderers (call-offs with delivery): Tenderers must have the capacity to transport and deliver products directly to Valøya or stated construction sites within the municipality ́s borders. Collection at the tenderer (call-off with self-collection): In order to ensure efficient operation, the contracting authority must be able to collect products themselves with separate vehicles. It is therefore a requirement that the tenderer ́s delivery place/storage place must be located within a maximum driving distance of 1 hour from the contracting authority ́s main facility at Valøya.
