• Description:
• The Municipality is looking for one (1) contractor to carry out the redevelopment of the Welgelegen district within the municipality of Haarlemmermeer. Neighborhood Renewal Project Welgelegen NieuwVennep is an integrated approach to the Welgelegen district in NieuwVennep. In this project the paving, sewerage and green renewed. The plan boundaries are roughly Venneperweg, Westerdreef, Noorderdreef, Wageningenstraat and Van Bemmelenstraat. In this district, the existing mixed system, consisting of a concrete sewer, will be largely replaced by a new mixed system of plastic, this is approximately 2,900 m sewer with a diameter ranging from 250 to 500mm.
