Project Overview

The project comprised of a live connection to an existing roundabout and roads and infrastructure works to a new 100-acre business park.

The scheme included 1.8km of roadwork, comprising 0.5km of double dual carriageway and 1.3km single lane carriageway, with one roundabout intersection. Cycle lanes, footpaths, grass verges with associated surface and foul water drainage, and utilities were included within the scope of the work. Extensive surface water drainage attenuation was constructed on the project, which involved the placing of 1,000m of 1.2m diameter steel attenuation pipework. The project required six culverted stream crossings, a 1.5km foul outfall drainage pipeline (350mm diameter) was extended outside the site boundary via a wayleave and included a 4m-deep pipe-jacked trenchless crossing (1.0m dimeter).

The roads, roundabout and footpaths were constructed in a combination of imported granite paving slabs, kerbs, edgings and granite setts. Road capping and sub-base material volumes equated to 140,000m³, of which 56,000m³ (40%) was site processed rock and lime stabilised subgrade to reduce off-site disposal.
