Roger Bullivant provided the foundations for the ExtraCare Charitable Trust as part of a major Birmingham regeneration project.
The retirement village located adjacent to the A453, Hagley Road in Edgebaston, is a 236 bedroom complex of affordable homes with care and recreational facilities. The site includes a leisure centre, IT centre, greenhouse, cafe, restaurant, gym and indoor bowling green.
The initial brief was to provide a cost-effective pile and beam foundation solution that could be delivered and installed safely within 10 weeks.
The chosen scheme comprised of RB pre-cast piles, pre-cast and cast in-situ caps, pre-cast beams and cast in-situ infills, steps, columns and bases.
To meet programming constraints and comply with residential noise restrictions two RB Quiet Hammer driven piling rigs were employed to install over 1,000 driven pre-cast concrete piles.
The piles were capped using a combination of pre-cast concrete and cast-in-situ concrete caps.
Where required starter bars were cast into the shear wall caps in preparation for follow on trades.
A total of 2,700 lin m of RB pre-cast concrete ground beams were installed. Split level construction saw steps accommodated with cast-in-situ stub columns constructed up to 4m high.
The entire foundation package was delivered in time and within budget.
