Decarbonization and Reuse of foundations in the construction stage More than recycling, reduction, substitution and the energy transition

Decarbonization and reuse of foundations in the construction stage has a huge impact for contractors with regards to the tender stage, project management and planning. The tender stage becomes more complex because there are more selection criteria to comply with, where in the past it used to be about planning and budget only. The reuse of foundation introduces uncertainty with regards to budget and planning. In order to implement reuse of deep foundations on a larger scale there is a need for more open dialogue between clients, contractors and engineers and other contract formats with appropriate risk allocation. The most significant potential for decarbonization of foundations is (in the implementation of reuse) in the design and design optimization because in this stage it is possible to influence (raw) material usage (Scope 3). The way current projects are documented can have a huge impact of the decarbonization and re-use potential of future projects.
