The project ‘De Passie’ has been accepted in the form of a DBMO contract, whereby Iv-Bouw, the contractor, is responsible for the design (from sketch to implementation design), building (construction), maintenance and operations. A DBMO contract is not something you immediately expect to encounter with an engineering and consultancy firm that specialises in installation technology. Han explains: “Previously, we only provided the design in projects; the design of the installations. It was then put out to tender and a contractor began work without us having any influence anymore on our design or what would happen with it. The tendering process takes a lot of time and contractors also often outsource activities to subcontractors. A few years ago, we thought ‘we can do that’, then we have a direct influence on what is being built as well as customer satisfaction. In the meantime, we have begun to do more and more ourselves in projects, and now, we not only design the installations, but we also take care of the procurement and we work with fixed self-employed professionals who execute the work for us.”
