Located in a commercial / retail area off Market Street, Bracknell, the former bus depot extends to 0.6 ha and sits adjacent to the local council office and Network Rail land (housing an electrical sub-station).
The site had a long history of various land uses and comprised areas of hardstanding, commercial unit and a vehicle garage with two above ground diesel tanks, fuel dispenser station and bus cleaning facility.
Further to demolition of above ground structures the all risk remediation contract required the removal of all slab and relics with remediation of hydrocarbon impacted soils, with full validation to meet site re-use criteria. Works were to be engineered to provide a working platform for The Grand Exchange residential development to comprise 242 apartments and exclusive resident facilities with collaborative co-working space as part of £770 million redevelopment of Bracknell centre.
The enabling phase remediation works were completed by DBR between January and March 2020 and comprised:
- Removal of all hardstanding and relics in conjunction with a watching brief for visual and olfactory contamination;
- Crushing of all slab and footings in line with DBR WRAP protocol;
- Decommissioning of site drainage system and interceptors with off-site tankering of silts and free oils;
- Off-site disposal of all hydrocarbon impacted and surplus soils;
- Agreement of RAMS for works in the BAPA co-ordinated with a watching brief from Network Rail;
- Site re-engineering to development platform level with temporary grip installations to protect site given delayed build contractor commencement;
- Validation testing and reporting to regulatory approval.
