Crummock were awarded the contract to act as subcontractors to BAM Nuttall to construct two new sections of carriageway, roundabout and associated carriageway works, as part of the Borders Rail Project at Shawfair, Edinburgh.
As part of the Borders Rail Development, due to the layout of the existing road network, realignment of either the proposed new railway line or the existing carriageway was required in the area passing through Millerhill/ Shawfair. The most economic option was realignment of the existing carriageway and a new road layout was therefore formed which involved construction of a new roundabout on the A6106 and two new sections of carriageway extending to 2,000 metres (RP13) and 700 metres (RP15) to the east and west of the new roundabout, with associated footpaths and street lighting. These roads connect the A6106 Millerhill Road to the Shawfair Park and Ride.
The carriageway and footway had to be constructed to adoptable standards by Midlothian Council. Crummock's management system is certified to NHSS16 (National Highway Sector Scheme). NHSS16 demonstrates Crummock’s quality standards that enable the company to lay asphalt on roads to adoptable standards, as required by Transport Scotland and local authorities. As part of the client's requirements, the kerb construction involved installing a kerb log and placing the new kerb on top. Crummock came up with a timber system which allowed us to speed up the process of installing the kerb log which resulted in the whole kerb construction being completed ahead of schedule.
All materials generated on site were reused on site in areas of embankment. Once the full earthworks were completed, this material was shaped and profiled in the embankment along either side of the carriageway to act as a sound buffer for the surrounding area.
