Project Brief
The 81 unit housing development consists of one and two bedroom bungalows and one, two and three bedroom houses.
Each home has been designed to adhere to Sustainable Homes Level 3, Lifetimes Homes Standard and has allocated parking for all residents.
Solution
The scheme was built over a former colliery leading to a difficult and challenging pile and foundations design. To mitigate the risk, it was decided to drill and grout the entire site which meant that all mine shafts had to be filled with concrete to stabilize the ground.
Colliery spoil deposits unsuitable to bear traditional foundation were found up to 5.2m depth. Therefore a total number of 658 piles were used as a foundation solution.
We worked closely with geo-technical specialists due to the acidic nature of tested ground deposits, designated concrete with chemical resistance was specified to be used for the foundations.
We liaised with the council highways planning department to obtain S278 and S38 works for adopted highways and with local water authority for S104 sewer adoption.
