Bartels & Vedder is an interdisciplinary engineering and consultancy agency that is specialised in innovative solutions for the construction, industry and offshore. In mid-2011 Chiel Bartels and Jelle Vedder have decided to join their respective forces to find appropriate answers to existing technical problems. This collaboration has led to a strong team of specialists who use an integrated and interdisciplinary approach and in addition to traditional construction, infrastructure and non-residential construction also serve the areas of offshore and floating. They do this, not only in engineering projects, but also by developing new products and supporting your product- and process developments.
