Infrastructure and Regeneration
We have been working to build and maintain the country’s road network since the 1960s and 70s when we became involved with site clearance on some of the south’s major trunk road schemes including the M2, M3, M4, M5 and M27.
Today our expertise comprises new road construction, road improvement schemes, carriageway widening, bridge construction and repairs. We are committed to delivering these projects for our customers to time and budget whilst maintaining journey time reliability and achieving defect-free completion.
We are involved in town centre regeneration through public realm schemes with completed projects including works in Bournemouth, Chatham and London.
Greenwich Swing Bridge
Customer: Galliard Construction
The project comprised the construction and installation of a new pedestrian cable-stayed steel swing bridge with approach ramps to carry the Thames Path over Deptford Creek. This is an adoptable structure which in time will be owned and operated by Greenwich Borough Council.
The main bridge was pre-fabricated off-site with the RBC project team co-ordinating and overseeing the fabrication process at the fabricator’s premises. The structure consists of sculptural, externally painted weathering steel plate with folded steel plates that conceals a short 9m backspan containing 120 tonnes of steel counterweight which balances the 44m main span as it opens. Following installation of the tuned mass dampers, together with the stressing of the mast and stays, the bridge was rotated into the service position using the permanent drive system to complete the crossing of the river. A high degree of engineering complexity was successfully managed by the project team including the provision of a sheet piled cofferdam installed on an inter-tidal terrace, which also acted as a piling mat for CFA piles, and significant amounts of back-propping to the existing basement, to provide adequate support for the 300T crane and construction traffic required to complete the works.
Customer: Dorset County Council
Raymond Brown Construction was approached to carry out the slope stabilisation and other works on the tunnel partial collapse of Beaminster Tunnel as part of the five year Dorset County Council framework.
The works involved site clearance and over 850 soil nails, which were driven into the slope and connected and tensioned to a TECCO mesh that covers and retains the surface layers. An erosion mat sits under the mesh to prevent soil washing away. Extensive drainage works were also undertaken to remove water from the soil nailed slopes and prevent surface water from adjacent ground running onto the stabilised area. At both the north and south portals, the end few metres of the arch were strengthened and waterproofed with reinforced concrete retaining walls. The wing walls on the approach to the tunnel were anchored into the slopes with soil nails drilled through the wall into the ground behind.
Haywards Heath Relief Road Phase 5
Customer: Crest Nicholson
Phase five included the section from the southern Bolnore village roundabout, a railway bridge over the London to Brighton main line and Rocky Lane including a new roundabout.
The first phase of the works included the reconstruction of Rocky Lane on the east side of the railway and a major earthmoving operation on the west side which involved a temporary road crossing over the existing road bisecting the site. The second phase included the realignment of Rocky Lane, Section 278 works, construction of the new roundabout and the tie in to a new railway bridge.
Over 50,000m³ of spoil was removed from the site, whilst the topsoil and sandstone will be reused as secondary aggregate to form backfill for the structures and for landscaping the completed works. Site clearance generated a large quantity of logs which have been made available to local community with the resultant chippings used as ground cover in replacement wildlife habitats.
Sandbanks Road Retaining Wall
Customer: Mossy Investments Ltd
The works comprised the construction of a contiguous pile retaining wall behind the existing brick retaining wall to allow for the development of two, three-storey detached residential properties, accessed via a single entrance off the prestigious Sandbanks Road.
The site lies at the top of Evening Hill which has a steep gradient sloping towards Poole Harbour. The existing retaining wall approximately 3.2m high and 25m long, together with a garage, shed and cascading flowerbeds were demolished once the new wall was completed.
The main aspect of the work was the construction of a contiguous pile retaining wall using reinforced concrete bored cast-in-place piles and a reinforced concrete capping beam with the installation of temporary support to the existing retaining wall during piling operations.
