Circular tendering?

It is not price that is the decisive factor when tendering projects, but the circularity of the solution. The focus shifts from minimum investment cost to minimum life-cycle cost.

In circular tendering, the licensing authority shapes the procedure in a way that encourages circular construction. Price as a criterion is no longer an issue, there is an investment budget and an operational cost and the market is challenged to come up with the most circular solution for that money. Circular criteria are issued such as a certain degree of reversibility, a certain percentage of reuse and the use of a certain number of circular materials, on which construction parties are scored.

In practice

At Bureau Bouwtechniek, we convince the project team of the benefits of circular construction and circular renovation. To avoid the often obvious demolition and complete new construction, we consider for each building what can be retained or reused on this or another site or needs to be renewed.

  • In the execution file, the circularity of the building project is included with a prelude to reuse, management and maintenance.
  • Contractors are persuaded to work in a circular way.
  • Manufacturers are sought who implement the circular principle in their business and offer innovative systems and materials.

Antwerp University carries out extensive LCA studies to provide numerical support for the circular idea. Our sustainability consultants are leading this research project.
