Glanville provided a complete engineering design service to St James Homes to redevelop a former sewage treatment plant into a development that consists of 800 new homes in a parkland setting, with very high quality open space, landscaping and infrastructure. Our involvement included extensive input to both outline and detailed planning applications, including flood risk assessments and off-site highway improvements. We developed a detailed surface water strategy incorporating SUDS to restrict discharges from the site and lakes for wildlife conservation and amenity use, as well as other water features such as formal quays and reed beds.
Large-scale site remediation was required and extensive ground modelling was carried out to ensure all spoil was retained on site and satisfied stringent planning conditions. The earthworks operation involved the movement of 300,000m3 of soil.
Various foundation solutions were implemented across the site to maximise the developable area whilst minimising the impact on the public sewer networks. The development included numerous structures and various construction methods, including masonry, timber, steel and concrete frames extending up to 5 storeys. Basement level car parking was incorporated that utilised reinforced concrete transfer slabs to support traditional construction on the floors above.
