Hughes and Salvidge won a competitive tender process to be awarded the contract to demolish the former Ford Engine Plant Factory at Bridgend, South Wales.

Our Scope of Works included Professional Lead-In; Site Establishment; Soft Strip to Offices; Removal of Asbestos; Drain Down and COSHH Sweep through all Buildings; Demolition of water treatment area to allow remediation teams access; Demolition of main factory; Demolition of offices; Removal of slabs and foundations; Removal of significant area of basements across the footprint of the site; Subsequent Earthworks and Civil Engineering Associated with Basement Removals; Backfill and compact site to agreed regime.

Asbestos containing materials were identified within the asbestos surveys completed. All asbestos removal works were completed by our licenced asbestos removal division prior to any structural demolition of buildings.

There was a requirement to keep some live power on site for the first 3-4 months of site works to maintain power to other live buildings while the diversion was being arranged.

There were ecology restrictions with the local waterways to be considered.

Remediation works in hot spots were planned and carried out. These were factored into the planning and sequencing of works.
