Construction of waste recycling facility and hard standing area on a former landfill site. The site’s original ground make-up comprised of approx 5m of household waste, covered with a thin layer of capping.
Works involved:
- Groundworks – 105 pre-cast driven piles installed up to depth of 12m, R.C. pile caps c/w holding down bolts, constructed on the piles in preparation for the steel frame building
- Ground bearing slab – (50m x 40m) – 200mm thick with 2 layers of A393 mesh and C60 concrete – a dry shake mix finish was applied for an abrasion resistance finish.
- Construction of 11m high cladded steel framed building (50m x 40m) with seven 6m high roller shutter doors
- Construction of 2500m2 of external hard standing – 200mm thick PAV2 concrete slab with single layer of A252 steel mesh
- Drainage – 550L/m of 300mm twin wall underground drainage laid for the surface water to then flow through a 14000 litre interceptor and into an attenuation lagoon. From here the water runs through a penstock valve and hydro brake, finally into a soakaway. A rainwater harvesting tank was installed to recycle rainwater from the WTS roof
- Reinforced concrete push walls – 110L/m, 350mm thick, cast in-situ, 4.0m high
- Office and welfare facilities (80m2) – constructed and installed
- Retaining wall – 50L/m, 400mm thick cast in-situ 1-4m high retaining wall, adjacent to existing access road
- Weighbridges – installation of 2 pit weighbridges
