Birmingham New Street
Birmingham New Street Station Phase 1
Birmingham Gateway Project
Coleman & Company have completed the demolition works to Phase 1 of the new £600 million pound regeneration of Birmingham New Street Station for Network Rail.
The works involved the removal of 8000 tonnes of concrete from immediately above one of the busiest network rail infrastructures in the UK and below a thriving city centre shopping centre.
The complex works entailed the removal of a reinforced concrete mezzanine floor slab from within the former NCP Pallasades Car Park. Without using any percussive methods or without imposing any additional noise, dust or vibration into the existing structure or immediate surroundings. All this performed from a floor incapable of taking the weight of the arisings from the slab we were demolishing.
Innovative DemolitionDemolition projects are rarely subject to such restrictions and so innovative approaches were essential. A series of specialist temporary works trusses were designed to support every conceivable length and weight of concrete beam. These trusses were positioned to support the beams as diamond wire saws cut them free from the structure and into 10 tonne sections. Purpose made low headroom gantry cranes were used to lift the cut sections from the trusses and out of the building.
Coleman & Company completed the project within a tight timeline, under a high level of environmental constraints & conquered the engineering challenges. Our excellent performance on Phase 1 of the project was instrumental in use being awarded Phase 2 which is already underway.
Scope:Demolition of existing mezzanine slab & associated internal structural alterations. Service strip out. Project welfare village and whole site security.
