What the buyer is looking for
Dredging works are part of the regular management and maintenance of the watercourses within the municipality of Lansingerland and are therefore a periodically recurring activity. In order to be able to prepare the necessary dredging activities in a planned and efficient manner, it is necessary to periodically determine which waterways are eligible for implementation in subsequent years. The municipality intends to conclude a framework agreement for carrying out the necessary preliminary investigations and monitoring of dredging. These preliminary investigations include determining the area to be dredged, carrying out soil and ecological surveys and other studies necessary for the preparation of dredging works. The results of these studies form the basis for compiling work packages for the already contracted dredger. The expected turnover for four years is € 380,000. The ceiling of the framework agreement for four years is € 494,000.
