The 80m approach spans for the new Medway Bridge, Kent, UK, were designed as continuous cast in-situ post tensioned concrete spans requiring an extensive formwork system to support the weight of wet concrete during construction. The solution adopted by the main contractor, Costain Skanska Mowlem JV, was to use giant temporary steel trusses to span between the piers onto which they could place the formwork for the deck. These temporary trusses were assembled from RMD components and weighed up to 800 tonnes each. DLT were sub-contractor to the JV for lifting these trusses from their assembly position at ground level, holding them whilst the decks were being concreted and then lowering them back down to ground level for re-use on the next span. We were also responsible for numerous other site jacking operations on this project, including the erection & dismantling of the traveling formwork systems used to construct the cast in-situ balanced cantilever main spans .
