Due to our extensive experience on the part of our clients and contractors, do we see which opportunities are being missed when there is no connection between the parties. This works in a counterproductive way for a project. We know the pitfalls and believe that with the right attitude and concrete measures a collaboration can be established. The continuous improvement of the collaboration between the parties is one of our main drivers and that gives us the justification to make concrete improvements, especially on the part of the client. The most influence by far can be achieved at the front side of a project. In the UAV-GC contract form, this influence is of crucial importance for a stable relationship between the client and the contractor.
