Germany – Construction work – Wastewater treatment plant: New biological treatment stage - Construction of utility routes

Opportunity description

E-B-5 - Construction of utility routes outside the scope boundaries of the main project As part of the construction of the new biological treatment stage at the Sindelfingen/Böblingen wastewater treatment plant, the existing trickling filter process of the second treatment stage will be replaced by a modern activated sludge process. As part of this project, the construction of a machine building is planned, designed for the integration of central plant technology. The subject of the invitation to tender is the construction of cable & utility routes outside the scope boundaries of the main project for the technical integration of the new treatment stage into the existing facilities. The work comprises the laying and construction of pipeline and cable routes for sludge, water and electrical utilities, including the civil engineering, surfacing, pipeline and cable construction work required for this purpose. The services offered comprise in particular: - Site setup, traffic safety measures and construction documentation -Removal and restoration of existing paved surfaces - Earthworks for pipe and cable trenches, including excavation, shoring, dewatering, temporary storage and reinstatement, construction-related explosive ordnance investigations - Laying of pressure pipelines for surplus sludge, floating sludge, service water and drinking water - Construction of pipe bedding, pipe encasements and trench backfilling - Core drilling and sealing work for pipeline and cable entries into existing structures - Supply and laying of empty cable conduits in various nominal diameters, including spacers, end plugs and blind closures - Supply and installation of cable pulling chambers, including chamber linings and structural calculations - Cable work, including laying medium-voltage cables provided by the client, mechanical cable protection, warning tapes, and grounding and equipotential bonding conductors - Surveying services, as-built documentation and quantity balancing The services offered comprise in particular: - Site setup, traffic safety measures and construction documentation -Removal and restoration of existing paved surfaces - Earthworks for pipe and cable trenches, including excavation, shoring, dewatering, temporary storage and reinstatement, construction-related explosive ordnance investigations - Laying of pressure pipelines for surplus sludge, floating sludge, service water and drinking water - Construction of pipe bedding, pipe encasements and trench backfilling - Core drilling and sealing work for pipeline and cable entries into existing structures - Supply and laying of empty cable conduits in various nominal diameters, including spacers, end plugs and blind closures - Supply and installation of cable pulling chambers, including chamber linings and structural calculations - Cable work, including laying medium-voltage cables provided by the client, mechanical cable protection, warning tapes, and grounding and equipotential bonding conductors - Surveying services, as-built documentation and quantity balancing Procedure: open.
