Reclamation of Longbenton neighbourhood to form
Platform for housing
Client: Yuill Homes | Value: £1.25million | Contract Date: 2003
The scheme comprised the redevelopment of a former inner city housing development to provide building platforms.
The original contract brief was to eliminate the potential for expansion that was apparent under existing building footprints. The original remediation strategy was to excavate this material and deposit it in a proposed recreation area.
Once on site it was apparent that the site had been worked on poor load bearing strata with extensive bands of running sand. Remediation strategy & working practices were therefore modified accordingly:
40,000 tonnes of material was excavated and treated using lime stabilisation techniques representing a significant value engineered solution
offered to the client.
Material was then deposited in an on site repository and material characteristics improved to achieve the end bearing specification of 160kNm-²
Area of sand extraction was infilled using site generated 6F2 crushed concrete.
Site volumetrics:
55,000m³ crushed concrete processed
removal & replacement of 12,000m³ of red shales
removal & treatment of 22,000³ running sand
