Abbey St Bathans, Scottish Borders
The Abbey St Bathans community hall site was situated in an area at risk to flooding associated with the watercourse, which sits along the bank of the Whiteadder Water.
Further evidence showed that the site's ground did not represent a suitable stratum for conventional foundations. The site's southwestern corner was of 'made ground', with an abundance of void spaces to consider at various levels underground.
Due to the project starting in the winter months, the early stages of the construction programme was time-sensitive to ensure the build was off the ground before poor weather closed in.
Site Survey & Load Testing
Liaising closely with the project engineers to understand all requirements, we completed a site survey and ground screw load testing to determine the depth of ground screw foundations required to achieve the target load-bearing capacity of 75kN SLS per ground screw pile.
Base System Design
To provide the secure anchorage required for the building, we designed and manufactured bespoke structural brackets in conjunction with the specified ground screws in quick time, allowing for continued installation without any delays.
Ground Screw Installation
To overcome the challenging ground conditions, our extendable ground screw foundations were driven to depths ranging between 3.7m and 4.1m to transfer structural loads through the upper soils and to a more competent load-bearing stratum.
