The tender specified that the award of the contract was not solely dependent on price. Price accounted for 50% of the points. The approach of the bidders to keep the CO2 emissions as low as possible counted for 30%, and the plan of approach together with the execution time of the works determined the remaining 20%.
These last two aspects actively contributed to winning the contract.
BESIX has adapted the construction methods and techniques for these works based on its experience in marine works. This allowed BESIX to propose a timeframe of 318 working days to complete the works. Methods to minimise CO2 emissions include an optimised logistics plan, extensive use of inland waterways and the monitoring of the logistics through a CO2 measurement plan.
