Baldock Bypass A505 – We had the job to construct a twin-bore tunnel on a fairly steep incline and had two changes of direction within its length. Special Formworks handled the design and supplied the materials; we also manufactured the curved forms for the semicircular soffit. The soffit forms sat on a mobile gantry designed and supplied by RMD Kwikform using proprietary equipment. The main contractor was Norwest Holst Ltd, and Boretech Ltd was concrete and steel fixing subcontractors.
