The project was for the widening and realigning of 600m of the B851, a road which links the A9 to communities south of Loch Ness. The existing section of road consisted of a single track road with passing places benched into a steep hillside with properties and a river below the road. The contract benefited from early contractor involvement to find a cost-effective retaining wall solution, utilising 1,750 no. mass concrete interlocking blocks (each 1m3) stacked up to 4 high, precast within 5 miles of the site.
Key Issues:
• Full use made of local suppliers – concrete, aggregates and surfacing sourced from quarries within 5 miles of the site
• Early contractor involvement to find cost-effective retaining wall solution
Principal Elements included:
Earthworks 14,000m3
Surfacing 4,600m2
Drainage 1,200m
Mass concrete interlocking blocks 1,750 no
