📋 Tender Overview
Contract awarded for Plant engineering lot-0001, title: plant engineering, description: for the water association dollern, a new drinking water treatment facility is to be constructed next to the existing facilities at the dollern waterworks. the treatment consists, among other things, of 12 open concrete filter basins. a new drinking water tank will be integrated into the building in the basement area to increase the storage volume (approx. 2,200 m³). due to the use for drinking water treatment, increased requirements for hygiene and material properties must be considered for the clean water tanks and filter basins. additionally, a new pumping system for network supply will be installed in the basement area. furthermore, several operational rooms, including offices, control room, workshop, storage, changing rooms, and sanitary facilities are planned. the construction will be a new solid construction (essentially reinforced concrete and masonry) of a drinking water treatment plant with water-impermeable reinforced concrete structures for a drinking water tank (approx. 2,200 m³ storage volume) as well as 12 open concrete filter basins (6 pre-filters, 6 post-filters) for drinking water treatment (each approx. 24 m² filter area) with pipe cellars and ancillary rooms. the scope of services for plant engineering essentially consists of: 900 m³/h treatment capacity (max. peak load) 6 raw water aerations (flat bed aerators) including ventilation systems 12 pieces of equipment for open concrete filter basins pre-/post-filters (pipelines, filter material, filter bottoms) 6 flat bed aerators (intermediate aeration) including ventilation systems equipment for drinking water tank flushing water pumping station and flushing air blower clean water pumping system (approx. 1,400 m³/h – 70 mws) 2 hydrophore tanks approx. 500 m pipelines nominal widths including dn 100 to dn 700 (stainless steel) approx. 160 shut-off valves nominal widths including dn 100 to dn 700 (mostly with electric drive) as well as various different fittings, measuring technology, ancillary work, and commissioning. estimated value excluding vat: 8594476.74 eur.Plant engineering
