Client: Balfour Beatty
Value: circa £19,000,000
Form of Contract: NEC Option D
Duration: 104 Weeks
Dates: January 2015 – January 2017
- Upgrading of 24km of motorway and two major junctions to a SMART Motorway scheme
- 200,000m cu excavated and 60,000m cu recycled and re-used on site
- 1,500 tonnes of material processed per day via a mobile crushing and screening facility
- Worked across 30 separate sites both adjacent to live traffic and a major junction connecting to the M25
Project scope The M3 near Lightwater in Surrey, between junctions 2 and 4a, is part of a major strategic road network connecting traffic travelling from the South West and Central Coastline into London, carrying over 130,000 vehicles each day. The route suffered with high levels of congestion and unpredictable journey times which has since been alleviated with the new scheme.
Working for main contractor Balfour Beatty on behalf of Highways England, MJ Church provided bulk earthworks and civil engineering expertise to carry out the upgrade across 24km of highway, divided into 5 sections, with various sections running simultaneously on both day and night programmes.
Earthworks on the scheme included the site clearance, bulk excavation and fill, processing of 1,500t of material per day on site using in-house mobile crushing equipment as well as landscaping, soil seeding and erosion matting.
Civil engineering works included drainage repair and upgrade, increasing the running lanes from three to four, deconstruction of two bridges, creating emergency refuge areas, installing new concrete barriers along the central reserve, installation of electronic signage boards and resurfacing.
