In contract 7009 PNSD groundwork and VA, water pipes and high-pressure sprinkler pipes will be built from manholes in Helsegata and into the hospital. The contract includes construction and water pipelines and surface water and sewer water pipelines around the entire hospital and a municipal pump station for sewer water. Surface water pipelines will be connect to both municipal pipelines and manholes and connected to the existing pipelines out in the ocean.
Guideways for electrical, high voltage, low voltage and ecom through this are and into the hospital. The interfaces with other contracts will be in the conduit manholes.
Contract 7009 will dig ditches and contribute with help for Drammen Fjernvarme AS. The works with district heating and district cooling pipes will be excavation, crushing and preparation of ditches before the start-up of Drammen FV's pipe contractor. Large parts of the terrain on the north side of the hospital will be raised with light matter. In these areas, digging will take place 1-2 metres down in the existing terrain in order to fill up with light matter. Different degrees of pollutions are anticipated in the matter that will be excavated. Mass replacement, delivery and laying or light matter and stabilising layer over the light materials will be carried out in this contract. A good portion of the pipelines are in the layer with light filling and it would be good planning to carry out the work in a rational manner. The works in this contract require extensive coordination with other contracts in the project. We refer to interface document C20 Interface for 7009 contract and general phase plans and progress plans. It is important that the contractor is well versed in this.
Execution of the works in this contract will be managed based on access to the different sub-areas the works are carried out in. Within defined phases there will also be a need for coordination and detailed progress planning. BIM and BIM coordinator and work planner.
In contract 7009 ground work and Water and Sewage there is a 3D model that is the basis for the work. Therefore it is important that the contractor has sufficient competence to take on, facilitate own works with the use of the model and be able to deliver correct measurement data in order to ensue correct as built information.
