The large-scale regeneration of the former Larner Road estate in the London Borough of Bexley into Erith Park has transformed an ex-local authority high-rise estate suffering from low demand and a poor local reputation. The award-winning two-phase development replaced eight high-rise blocks with 588 homes for rent, shared ownership and market sale.
For the O’Keefe Group, the earthworks and soil stabilisation works post demolition of the existing tower blocks involved major (40,000m3) cut-to-fill operations with challenging settlement criteria and access restrictions. This mitigated the requirement of some of the piling within the scheme. Following the cut-to-fill operations, the infrastructure of the road scheme was carried out concurrently with the foundations building of the housing units.
The project was phased over three years which necessitated the O’Keefe Group to carry out foundations and infrastructure while external works and residents moved into properties in the first phase of build. However, the O’Keefe Group was awarded subsequent packages of works which involved services diversion and major drainage alterations, again while residents moved out of their properties on the old development and into their new ones. The thoroughfare for residents was key in the programme delivery. Part of the major drainage works included the largest precast manhole chamber constructed in the UK which received recognition at the Pre-Cast Awards in 2016.Read full case study here
