Midlands based demolition contractor and C&D Consultancy customer AR Demolition has successfully completed a high profile bridge dismantling contract, removing a disused rail bridge spanning the A444 Weddington Road in Nuneaton, Warwickshire.
The contract for British Railways Board (BRB) was undertaken over a three week period to include preparation works, but the final dismantling and removal of the bridge decks and main supports was completed in under 24 hours, a full day ahead of the allocated schedule for the road closure.
The former double track railway bridge spanning the road was constructed in 1972, but after only a few years in service, it was closed along with the entire line, following the Beeching Report. Still under the ownership of the BRB, the bridge demolition was commissioned as part of the company’s non-operational asset rationalisation programme.
The deck was originally constructed using steel trusses and beams and mass-filled with concrete to carry the tracks overhead. The bridge was supported at each end by traditional concrete abutments and from beneath by two pairs of 11 tonne steel legs.
The structure was stripped back to its primary frame and the deck was gas cut into 6 sections weighing between 13 tonnes and 24 tonnes each. AR Demolition used a 230 tonne crane to lower each of the sections and both steel legs down onto crash decks where the pieces were further cut down for transporting off site.
A Temporary Traffic Regulation Order for closing the road over the weekend 24th/25th September 2011 was granted to AR Demolition and work commenced on demolishing the structure at 3.00 am on the Saturday morning. The main work was completed by 11.30pm on the 24th, 24 hours ahead of schedule.
British Rail representatives were on site monitoring the contract and reported back favourably on the professionalism and high standards adopted by AR Demolition throughout the job.
