More Info

The Main Contract was for the design and construction of two grade-separated junctions on the A77 Trunk Road at Symington in South Ayrshire.

Hillhouse Quarry Group Ltd initially secured the supply of all aggregates and concrete to the project with the road surfacing sub-contract being secured in December 2013.

Between contract award and completion in May 2014, various road make-ups and footpaths were installed on or adjacent to the existing A77 Trunk Road, the surrounding surface roads which are maintained by South Ayrshire Council and a number of private roads such as at Hansel Village.

In total, more than 30,000m2 of surface course was laid on the roads and approximately 13,500m2 of footpath was constructed.

The initial order placed with Hillhouse for the surfacing works was for £1,325,000 with all works being completed on programme and within budget.

This project was undertaken to eliminate the flooding and risk to vehicular and pedestrian traffic making use of the Dean Ford, Kilmarnock.

Previously, the Dean Ford flooded on numerous occasions every year during periods of heavy rainfall, resulting in stranded vehicles, road closures and traffic diversions round the town centre.

The ford itself had been in poor structural condition and required regular maintenance to prevent debris causing blockages. The solution was to construct a new road bridge incorporating pedestrian footways thereby permitting the removal of the nearby Lauder Footbridge which had been in place since 1905.

The surfacing works included:

  • Planing of tie-ins
  • Regulating
  • 2,000m2 of carriageway surfacing
  • 1,500m2 of footway and footpath surfacing
  • Construction of 6nr speed tables

Moorfield Industrial Estate is situated to the west of Kilmarnock and only a short distance from the A71. The project was the extension of the existing industrial estate infrastructure (roads, drainage, lighting and utilities) along with the provision of a speculative 25,600sq ft industrial unit which was suitable for future sub-division.

The site was situated adjacent to an existing busy industrial estate. This required a site specific traffic a management plan to be implemented to minimise the impact on neighbouring businesses.

The short haulage distance from our coating plants at Troon enabled us to maintain a constant supply of material to the paver whilst utilising the minimum number of tippers.

The surfacing works included:

  • 8,000m2 of carriageway surfacing
  • 2,000m2 of footway and footpath surfacing
