These works comprised the full reconstruction of a carriageway on a slipped embankment, part of the Old Dalkeith Road which passes through the Sheriffhall Roundabout and becomes the A6106 which serves Eskbank and Dalkeith. A section of road near Lugton Brae suffered a serious landslip and was completely closed to traffic.
Work initially started on site in January 2013 with drainage checks and excavation of investigatory trial pits. Works included excavating approx. 16,000m3 of material from site, putting 140 piles in place to create a solid wall to interrupt the slip cycle; as the piles were being set, soil anchors were fitted at an angle and depth of 6m into solid rock, every 3m to connect with the piles. A capping beam was fitted to hold the piles and soil anchors together to create a structure strong enough to prevent any future slippages. Thereafter the embankment was rebuilt, further drainage installed and finally the carriageway was reconstructed. Crummock worked closely with Midlothian Council on the design for the pile work to complete the work as economically as possible for the Council without compromising the strength of the structure.
