Weekend Flyover Demolition
The S Evans & Sons team were selected to safely dismantle and dispose of Perry Bar Flyover on behalf of Tarmac and Birmingham City Council, as part of the Perry Barr Regeneration scheme. Our works included the mechanical demolition and disposal of two 50-year-old structures, a single span concrete footbridge and a multi span concrete deck flyover supported by steel, including each abutment, and supporting piers.
During a weekend possession (February 5-8th) four excavators worked simultaneously each fitted with hydraulic breaker and pulveriser attachments to remove the concrete deck, once the steel supports were exposed two excavators equipped with 9te shear attachments worked in tandem to cut and lower the main steel supports. The abutments and piers were the reduced down to ground level and all arisings were removed and transported to a local compound for crushing. Over 300 loads of crushed material were removed from site and recycled for other projects within Birmingham City, all the steel was processed and recycled.
To minimise disruption to the local highways and public we programmed the work so the spans 1 and 2 were reduced during Friday night, the traffic management was then reconfigured early Saturday morning allowing a bus route that ran adjacent to the worksite to open during the day. The ground protection was then transported and repositioned under spans 3, 4 and 5 preparing the site for the demolition of the final 3 spans during Saturday night and into the early hours of Sunday Morning.
The works were completed early hours of Monday morning and the road reopened ahead of schedule.
The project was carried out successfully with no incidents and to the client’s satisfaction, and due to the success of the demolition we were awarded further civil works within the scheme.
A great team effort to all involved.
