PROJECT DESCRIPTION
This is a new build Motorway Service Station constructed on an environmentally sensitive Greenfield site, for Swayfields (Folkestone) Ltd, part of the Swayfields/Extra Group of Companies.
The project was to build a new 24/7 operational filling station with a sales building, carwash and plant room, generator compound, canopy structure and an above ground reinforced concrete vaulted fuel storage facility that is landscaped over.
The sales building is a steel framed structure with a metal insulated composite roof and built up insulated wall cladding panels, the total floor area is 420m2, and it is built on a pre-cast concrete piled heavily reinforced concrete raft. The carwash, plant room and generator compound are of similar construction.
The canopy covers the PLG and HGV forecourt and is in total 1364m2, it has a fully floating glazed link between the main canopy structure and the sales building, the structure was built on driven steel cased piles and 14 heavily reinforced pile caps.
The fuel installation comprises of four super vault tanks in an above ground fully accessible vault totalling 390,000 litre capacity, an above ground LPG tank, new double contained fuel pipework, seven PLG fuel dispensers, one combined PLG and LPG fuel dispenser, three HGV fuel dispensers, the tanker off loading and fuel delivery system is based on a pressure system. The Super Vault tanks are built within an above ground reinforced concrete vault approximately 400m2 in area and 4.5m high, it has a PCC roof over, two access tunnels and is fully tanked to eliminate fuel escape into the ground in the event of a spill and to prevent water ingress, the entire vault is completely buried in the hill side and landscaped over, it has a natural stone gabion wall to retain the earth to the forecourt elevation of the structure.
The forecourt is surfaced with 2200m2 of brushed finished concrete and 2300nm2 of stone mastic asphalt. The remaining areas are laid to landscape, drainage to the forecourt is via Aco drain channels and 3 forecourt superceptors with shut off valves, the system discharges into a pumping station then onto an on site attenuation system.
In total there are 294 load bearing and tension piles installed to support the structures and above ground tank vault. As the site was in a low area the exiting ground levels had to be raised and are built up with approximately 14,600 tonnes of imported stone which was laid in layers and incorporated reinforcement geogrids.
The shop building was completely fitted out to the client's requirements.
