PROJECT DESCRIPTION

A former quarry was being developed for the construction of approximately 100 residential units. The site was steeply sloping in parts and had suffered from some historical slope stability issues. In order to accommodate the proposed building layout the site was subjected to significant earthworks requiring the incorporation of retaining structures such as Crib walls, and re-enforced earth slopes.

BWB undertook earthworks design, slope stability assessment and design of the use of reinforced earth to stabilize the major slopes. In addition BWB designed a Japanese Knotweed containment cell to EA requirements.

Key Challenges

The main challenge was to come up with an economical and safe design that precluded the use of piles, whilst still being able to stabilize the main slope failure on the site.

BWB were able to design away the use of sheet piles on the site in favour of cheaper alternatives such as criblock walling and reinforced earth slopes.
