Procurement approach Tendering followed the open procedure in combination with the most econo
advantageous tender (MEAT approach.
MEAT procurement as a tool to select a) the contractor with an
efficient working process, and b) the one that also offers the product with the
lowest environmental impact. The MEAT approach includes a pricing of both the quality of
the working process and the quality of the environmental impact.
In the tender Rijkswaterstaat favours companies that organi
working processes efficiently by deducting a fictional amount of money from the
bidding price. The higher the efforts to reduce CO2 emissions, the higher the

adder, see www.skao.nl.

Lessons learned• The new procurement method was applied successfully and Rijkswaterstaat will continue

provided with functional requirements and technical framework conditions. The market
appreciates this approach.
• The client must have a well

emission should outweigh the tendering costs. It is therefore necessary to perfor
