Anyone who thinks that an all-round GWW contractor mainly executes what has been thought up is underestimating the impact of a smart approach in the preliminary phase. It is precisely by sitting at the table early on, daring to take risks and optimizing technical choices together with partners that scope is created for efficiency, cost savings and quality. It is precisely this way of working that distinguishes Kleywegen, leading to savings of no less than 30,000 m3 of sand supply and removal at the circular city block Robin Wood on Centrumeiland in Amsterdam.
As an all-round contractor in the GWW sector, Kleywegen operates across the full spectrum of outdoor space. From road construction and hydraulic engineering to complete site design and roof gardens, the company takes care of construction companies and developers from start to finish. “It is precisely this broad scope, combined with a strong preference for working together in construction teams, that makes us a valued partner within the construction column,” says director Jelle van der Kleij. “As a team we prefer to be at the table as early as possible, to think along, to advise and to participate in the risk where necessary. This transparent and thoughtful approach appeals to the target group and often forms the basis for long-term collaborations.”

So too with Slokker Bouwgroep, a collaboration that originated with an earlier project on Cruquiuseiland in Amsterdam. That led to this follow-up assignment for Robin Wood. “In this project, we are taking care of all work in the outdoor area, from site layout and groundwork to drainage, sewer construction, water retention and infiltration crates and finally the paving,” says Krijn van Zandwijk, foreman at Kleywegen. “Ground improvement for tree and planting areas also falls within our work package.” In the preliminary phase, Kleywegen already participated in the construction team. “Together we thought about the approach to the construction pit, the pile driving and the handling of existing cables and pipes. In total, we moved about 5,000 m3 of soil and several pile heights were optimized. This allowed some 30,000 m3 to be saved on sand supply and removal.”
Van der Kleij emphasizes that it is precisely this thinking along that makes the difference. “Together we look at how things can be done more efficiently, save costs and help each other. Moreover, we are not afraid to take responsibility and take on risk. Together we put our shoulders to the wheel. That is the basis for a successful project,” says Van der Kleij, who reveals that the next project for Slokker Bouwgroep is already in the pipeline.
