Project Overview

Dawnus have successfully completed three design and build projects to construct new Household Waste Recycling Centres (HWRC) at locations across Cornwall for our client SITA UK. 

The St Austell HWRC site required an extensive cut/fill operation, with approximately 5000m³ of soil being excavated and re-profiled and a further 3000m³ of fill material imported to make up the finished levels.  The project also involved installation of all storm and foul drainage. 

We designed and constructed approximately 200 linear metres of precast retaining wall units to create the level separation, as well as placement to designed levels of over 2500m² of reinforced concrete slab surface for HGVs, and 1400m² of asphalt car park; placement of kerbs, fencing hand-rails and light-columns throughout; supply and commissioning of new site office and provision of a suitable finish at site entrances to allow the local highways authority to tie-in. 

The scheme at Falmouth was a similar facility to St Austell, involving design and construction of a HWRC. The site works included a new access road, excavation of circa 3000m3 and construction of 235m of in-situ reinforced concrete retaining walls to provide the grade-separation for the public to unload waste to the individual containers. Site works included 2,600m2 of tarmac surfacing to access roads and circulation areas, with 1900m2 of concrete hardstanding to storage, waste handling and lorry turning areas. 

The final site at Launceston involved design and construction of a split level HWRC in the Penygillam Industrial Estate. The RTS building has in-situ concrete 4m high push walls for transfer to other facilities. Works included a reinforced earth road embankment, extensive retaining wall construction, storm-water attenuation and control, with consideration for waterborne contamination and two weighbridges with signal control systems.
