Roads, Bridges and Development
Infrastructure
Our Civil Engineering services include highway and development infrastructure schemes for both public and private sector clients. Projects range from major trunk roads and award winning bridges to residential estate roads and car parks. The company’s commitment to teamworking and quality workmanship in this area has been recognised through a number of industry awards and repeat business from key clients.
Key highway activities carried out include:
|
- Cycle ways, footpaths and pedestrian crossings
- Pedestrian subways, underpasses and culverted watercourses
- Bituminous surfacing including asphalt, anti-skid and reinforced overlays
- Concrete roads, pavements, storage areas, service yards and loading areas Block paving including patterned machine laid areas up to 24,000m2 for major distribution centre service yards
- Speed control measures
- Street lighting and signing, barriers and fencing
- Foul and surface water sewers to development areas including off site sewers
- Highway drainage, interceptors, SUD’s balancing ponds, flow control structures and outfalls
- Utilities installation & management including installation of ducting and service trenches
- Co-ordinating diversion works by multiple statutory undertakers.
- Phased traffic and pedestrian management including working in busy town centre environments
|
In bridge construction our experience includes:
|
- Road, river and footbridges in pre-cast concrete, in-situ reinforced concrete and steel
- Bridge abutments including sheet piled cofferdams and cfa piling
- Bridge deck replacement and waterproofing
- Bridge re-construction including listed structures, brickwork and masonry
|
In 2004 we completed the construction of an innovative and award winning 15.0m single span skewed arch bridge across the River Weaver as part of the A534 Kingsley Fields Distributor Road, Nantwich, Cheshire. The ‘Sir Thomas Fairfax Bridge’ main span was constructed from pre-cast concrete arch beams, spandrels, parapets and cap stones supplied by Macrete (Ireland). The pre-cast spandrel elements were faced with cast-in brickwork which was matched in-situ for abutment completion. Bridge abutments required construction of sheet piled cofferdams and CFA piling with in situ reinforced concrete pile cap and abutments. A pedestrian walkway was incorporated through each abutment with lighting and drainage.
The innovative design was chosen to blend in with existing bridges in Nantwich and also to minimise the significant environmental and temporary works constraints associated with the river crossing.

| The ‘Sir Thomas Fairfax Bridge’ over the River Weaver was awarded The 2004 Concrete Society Award for Small Civil Engineering Projects, The Institute of Civil Engineers ( NW region) 2004 Merit Award and the Institute of Structural Engineers (NW region) Small Project Award 2004. |
- Redundant subway and underpass infilling.
|
The Company has carried out subway infilling using a number of different techniques such as foam concrete, sand or grout infill. We have recently developed a cost effective surface based underground void infilling system which has been used to infill 9 redundant sub-ways in Telford.. Based on its dual head drilling rigs and using an auger fed rotary spinning material distribution unit to spread infilling materials, material can be spread up to a 15m radius from the point of infilling.
Subways are infilled from single mid point infilling positions using the modified drilling unit. Infill materials such as lean mix concrete or cement bound stone are delivered by truck mixer and discharged into a feed hopper.
The small footprint of the unit allows the set up points to be chosen to minimise traffic disruption and traffic management requirements. Headwalls are constructed at each end of the subway and each subway in filled in a day.
