Kolsteren Projekten is a VCA**-certified main contractor. We are very proud of this, since VCA** is the highest degree of certification a main contractor can obtain within the Netherlands. VCA-certification is the Dutch equivalent of the Safety Certificate for Contractors (SCC).

VCA**-certification entails that a company fulfills the structural, policy and planning guidelines regarding safety, health and the environment. It is an addition to the VCA*, designed especially for main contractors. By holding this certification, Kolsteren Projekten creates an as safe as possible working environment for all parties involved.
