Earthworks
Royal Airforce Museum, Cosford - Works encompassed topsoil and subsoil strips, breaking at isolated bases and tarmac paving, to facilitate bulk dig for the foundations of the new building.
Weeford to Fazeley A5 Improvements - £3M earthworks contract, involving removal of 1 million cubic metres of earth. This was an ECI project for the Highways Agency.
Earthworks/Regeneration - Gibfield Park, Leigh - An urban regeneration scheme to make disused land suitable for mixed development.
Biddulph Bypass - The contract was for the excavation of 70,000m3 of material to be used in cut and fill operations.
RMC Western Region - Term Contract - Greyhound carried out all earthworks for the RMC Western Region area. The key criteria for RMC being demonstration of management of health and safety issues, project management skills, location and resource levels.
New Cut Wern Argae - Welshpool - A flood defence project for the Environment Agency. We carried out topsoil removal and storage, development of access routes, importation of 100,000m3 of impermeable clay, and construction of 1.6 km of clay flood bund.
Hereford Quarry - Involved excavation and deposition in various on site locations, together with the formation of drainage ditches consisting of filled granular material with terrain filter wrapping.
Birch Coppice Dordon - Site preparation and remediation works for the construction of a new P&O rail freight terminal covering approximately 50,000m2.
Landfill
Sidegate Landfill compost pad - The project consists of a 5,000m2 tarmacadam bed and lined lagoon of 500m3 capacity, kerbing and drainage together with a screening bund of 10,000m3
Packington - Involved excavating 100,000m3 of material, new access roads and 1800m of site drainage.
Hill and Moor Waste Site - 300,000m3 clay capping to CQA standard was required to complete the phase I landfill, together with the construction of a second cell. A new surface water management system and interceptor surface water ditch were also required.
Deerplay Site - Cell 5 - Involved excavation, handling, transportation and compaction of 200,000m3 of on site material.
Betton Abbots Site - Included importation of 11,000m3 of impermeable clays and 5,000m3 of leach drainage stone, with bulk excavation of over 20,000m3 of site won materials reused on restoration of previously filled cell cap works.
Deerplay Site - Cell 4 - The project initially required the clearance of the 13,000m2 cell footprint which involved the excavation of 45,000m3 of sandstone, 6,000m3 of shale and 25,000m3 of engineered soils.
Barnsley Lane - Involved excavation of 7,500m3 of material and the placing of 7,500m2 of geotextile and plastic membrane.
Reclamation and Remediation
Nar Ouse Regeneration and remediation - The Nar Ouse Regeneration Scheme (NORS) was the first of the Nar Ouse Regeneration Area (NORA) scheme and involved clearing the contaminated land within the site and building the Nar Ouse Regeneration Route (NORR).
Derby Sewage Treatment Works - Refurbishment of the Derby Sewage Treatment Works, this project was carried out over several phases and involved demolition of slabs, humus tanks, bacteria beds and sand filter buildings.
Weeford Quarry - Construction of a new lagoon in two sections together with associated bunds and drainage.
Bumpers Lane Scrap Yard, Chester - Job was to remediate a disused scrap yard and waste transfer station to current remediation regulations and guidance. Part of the contamination to site was 2,000m3 of difficult tyre waste.
Roadworks
A47 Thorney bypass - The project consisted of a 5km dual carriageway built on an average of 1.5m high embankment; consisting of some 200,000m3 of site won material generated from an online borrow pit and placed on Terram Geogrid.
A5 Nesscliffe Bypass - Earthworks content involved moving 400,000m3 of material, much of the excavated muck was re-used to minimise importation and disposal costs, with the added benefit of limiting vehicular movements in and around the area.
South Stockton Link Road - Included stripping of topsoil, cut and fill bulk earthworks, importation of acceptable materials and granular fill for structural back fill, placing and compaction of capping and sub-base layers.
Hodnet Bypass A53 A442 - Excavation quantities for the projects were 450,000m3, most of which is selected for reuse on the project to mitigate import and disposal costs.
JCB Factory - The works consisted of excavation, site clearance, new drainage and placing of sub-bases and bases to the new road alignments, together with kerbs and beanie blocks, new fencing and landscaping.
Blackpool Tram Track Renewal - Involved the excavation and renewal of all track ballast, relaying geogrid and geotextiles beneath the ballast and providing drainage to either side of the track.
Rail
Tame Valley Structures - Working alongside the busy West Coast Mainline this Network Rail project involved the reconstruction and extension of existing railway embankments within the Tamworth to Lichfield area
Trent Valley Tracking - This particular scheme involved the creation of nineteen new access roads covering a total of 18km between Lichfield and Tamworth, Staffordshire.
Other
Mwrog, Ruthin - Construction of 1.5km of new ditch works and the widening and deepening of 1.5km of existing ditch. Also involved was the construction of box culvert structures.
Alston Impounding Reservoir Improvements - Stabilisation and strengthening works to two reservoirs with materials won from a third downgraded reservoir.
Sinderland Brook river restoration - This scheme was the largest restoration project of its type in the country, some 1.8km long.
