|Main Contractor:||Balfour Beatty Civil Engineering Limited|
The new motorway replaced an existing stretch of the A77 – a notorious accident blackspot – and diverted traffic away from Busby, Eaglesham and other surrounding communities. It also significantly improved journey times between Ayrshire, Glasgow and beyond.
We were contracted to carry out the planing and re-surfacing of 77,000m2 of M77 motorway between Junction 5 Maidenhill and Junction 7 Fenwick. The works included areas on both the northbound and southbound carriageways.
The site was made available during Sunday to Friday night-time closures between the hours of 8pm and 6am. Typically, 2,200m2 of carriageway was planed to a depth of 40mm and reinstated with hot rolled asphalt each night. The pre-coated chippings were required to have a minimum 65psv and all planings were returned to Hillhouse Quarry for recycling.
The nature of the works and the requirement to re-open the newly surfaced areas in time for the morning commute meant significant amounts of resource (both labour and plant), were required.

This high profile contract was located in the centre of the town of New Cumnock. The works involved the upgrading the existing road to improve its design life.
The scope of works included:
- the removal of 4,500m2 of existing road surface by cold milling

- installation of new footpaths on both sides of the road
- re-alignment and re-profiling

Due to the restricted working widths available the works were carried out under a convoy system. This was required to ensure the safety of the public and workforce and to maintain the safety zones.
