A83 landslide barrier work completed

Bam Ritchies has successfully completed construction of landslide and debris barriers on the Rest and be Thankful section of the A83 for Transport Scotland.

The work was part of a second phase to protect areas of the route that were identified as presenting road users with a higher risk of disruption from landslides.

Ritchies started work on installing an 88m Geobrugg SL-150 shallow landslide barrier, a 38m wide Geobrugg UX-120-H6 debris barrier and a smaller ‘in-channel’ VX barrier during the summer. Construction of the barriers has been completed on time despite disruption caused further landslips close to the work site.

The new barriers have been anchored using 35mm and 43mm galvanised GEWI + bars installed to depths of between 8m and 16m, which were installed using a combination of A65 crawler mounted drill rig and Tirfor supported Ripamonti drilling rig using a down the hole hammer.
