Using modern construction methods, our three sister companies, TDS, Design4Structures and Cadcoe, constantly work together to innovate our industry. We believe that innovation through collaboration is the key to the future of construction, which is why we have officially joined together to form the Technical Design Services Group (TDS Group). In doing so, we are confident we can produce designs of the highest quality which continue to surpass the expectations of both our clients and the industry as a whole. With TDS working as a sub-contracting design office, D4S as the structural engineers and the Construction and Design Centre of Excellence, also known as Cadcoe, running a state of the art training programme, the TDS Group will pave the way for the future of the construction industry.
