Log Cabins in the Cairngorms National Park

Log Cabins, Cairngorms

As part of a multi-phase project, we carried out site surveys and load testing to prove the viability of ground screw piles in the mature woodland. To date, we have completed the installation for this project's first and second phases, the third already on the horizon.

Log Cabins in the Cairngorms National Park Overview

Low-impact foundations in a treasured national park

Situated within mature woodland in the Cairngorms National Park, all work needed to be completed while protecting the natural landscape, with the use of heavy plant machinery strictly prohibited.

The access to each installation site was significantly restricted, with varying ground levels and conditions requiring an imaginative and versatile approach to ensure robust foundations for each log cabin.

Installation for the first phase of log cabins was to be completed in November/December 2019, while weather conditions in the Cairngorms can be the biggest challenge.

Site Survey & Load-Testing

Working on-site with project engineers, we completed a site survey and ground screw load testing to determine the specification of ground screw foundations required. Liaising with architects, we confirmed layouts and designs for the project's first phase for six log cabins.

Base System Design

After successfully installing all 132 ground screws, surveys on each site determined the remaining levels needing to be brought up over the sloping and uneven ground. Individual extensions were fabricated, returning to the sites for final installation to provide each log cabin's secure and level base.

Ground Screw Installation

Working carefully around the mature woodland and deploying our electric-powered turning machines, the installation of 132 RDX PRO RF140 76mm for phase one's six log cabins was completed to schedule.

The second phase of this project was completed two years on in December 2021 for a further six log cabins, and the third phase is already in planning.
