Building foundations with Screw Piles, Community Hall, Abbey St Bathans

Overview

Bringing a community together

The Abbey St. Bathans community hall site was situated in an area at risk of 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 were time-sensitive to ensure the build was off the ground before poor weather closed in.

Solution

A steadfast foundation solution overcoming challenging ground

Site Survey & Load Testing

Liaising closely with the project engineers to understand all requirements, we completed a site survey and 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. We used our advanced ground screw machines, expertly managed by our screw piling team.
