SPEEDECK designed & built piled raft foundations for 22 residential units, consisting of 2 storey housing on this first section of the meadows development with Bellway Homes. These were all the plots denoted for piling within this first phase of works, with the remaining 30% of units being constructed as shallow strip foundations, by others. This marks the first involvement for SPEEDECK within this development, with several hundred remaining units left to be constructed.
The Geotechnical challenges present on this site which led Bellway to reach out to SPEEDECK were:
High water table, meaning the excavation of deepened strip foundations was difficult.
SPEEDECK identified and mitigated the risks above utilising the following techniques and experience:
A CFA pile was chosen using a lightweight rig, which optimised for pile speed installation while maintaining minimal pile matt requirements. SPEEDECK utilised their CWS along with localised soil stabilisation to minimise dig depth, muck away and imported aggregate costs.
SPEEDECK’s scope of works consisted of:
The pile attendance, muck away and underslab drainage works were completed by the groundworker.
SPEEDECK successfully completed their scope of works within programme, delivering the 22 units & garages within the 7 weeks.
The first 11 units were handed back to the client in less than 5 weeks.
SPEEDECK’s success on this project, for savings both time & money, was realised through being awarded the following parcel of works for the next 212 units.
As a leader in the design & build foundations market, and the iterative learning through completing hundreds to thousands of units every year means SPEEDECK are able to deliver the most efficient designs using simplified construction to maximise project savings while minimising time on site.
The project is fully complete and signed off by the client and warranty provider with the next package of works on this large development successfully secured.
