Hughes and Salvidge recently completed an intricate and time-critical project to demolish the North Fareham Farm Footbridge over the M27 motorway in Hampshire.
Situated between Junctions 10 and 11 of the M27, we were contracted to demolish the bridge in its entirety within a 24-hour window to allow the client to minimise disruption to users of the major trunk road.
The motorway was shut at 10.00pm on the Friday night and was required to be re-opened again by 9.00pm Saturday night.
Our scope of works included protecting the duct work and grass areas under the bridge, along with the motorway road surface itself, both underneath the bridge and in the immediate vicinity of the works.
We started our works at 11.00pm and within the first 4 hours had laid all the protective measures – which included a layer of gauge terram, topped with 18mm ply sheeting, and further covered with 300mm of crushed material to 6F2 specification.
Immediately under the bridge itself, the layer of 6F2 crushed material was increased to 500mm and on the grass verges a 100mm layer of Ekki Mat was also added to the protection system.
Once the protective measures were in place, at 3.00am 4 x 50-tonne excavators then rolled in and began the structural demolition of the bridge itself.
By 10.00am Saturday morning the bridge was down and the processing of the arisings and clean-up operation began.
We had 10 operatives on the night shift and 10 more on the day shift, and by 6.00pm on Saturday the project was completed and the road surface handed over completely clear and ready for re-opening – ahead of schedule.
The project was an impressive operation and a credit to all involved within the company, as pinpoint organisation and planning, combined with consistent and accurate communication and collaboration allowed this project to be completed safely, within the required timescale, and to the client’s satisfaction.
