Case studies

Aberfeldy Village

Aberfeldy Village is a major part of Poplar HARCA’s plans to reshape the area. The development comprises multiple phases to be carried out over a 10 year period. To date, CampbellReith has provided full civil and structural design services for Phases 1, 2 and 3 of this 1100 unit regeneration project.

The JV of Poplar HARCA & Willmott Dixon Regeneration creates a new community of over 1200 homes together with a village centre providing retail, health and community facilities.

Aberfeldy Village is a major part of Poplar HARCA’s plans to reshape the area. The development comprises multiple phases to be carried out over a 10 year period. To date, CampbellReith has provided full civil and structural design services for Phases 1, 2 and 3 of this 1100 unit regeneration project.

Phase 1 comprises 3 blocks from 4-12 storeys high, with 338 units of sale, market rent and affordable accommodation. Phase 2 comprises 227 residential units in two blocks up to 8 storeys high. Phase 3 comprises 346 units in four blocks, with a two storey NHS Health Centre, Community Centre with a two storey high column free hall and the new estate Energy Centre provided in the lower floors of the blocks. Single level basement car parks are provided in one of each of the blocks in each Phase.

Floors are RC flat slabs with a power float finish and acoustic mat to receive direct floor finishes. Columns are of slender ‘blade’ configuration concealed in party walls and the inner leaf of external walls. Lift and stair core walls are of RC construction.

For Phase 2 and 3 of the project the columns and core walls are precast concrete, with insitu RC slabs. Precast columns and walls have been selected by the contractor to speed construction and maintain construction quality. The detail design of the precast elements’ connections is undertaken by the precast specialist sub-contractor. Foundations are bored in situ CFA RC piles to the main concrete frame. The car park basements have a perimeter steel sheet pile wall which is designed to support the vertical loads of the perimeter columns as well as the retained ground.

Surface water drainage was required to attenuate the rainfall on the development to greenfield runoff standards. Working closely with architects Levitt Bernstein.

CampbellReith developed a proposal using an urban swale alongside an avenue of trees forming the main features of a linear park through the estate, with storm cell attenuation trench below the surface trench to provide the necessary overall water attenuation capacity. The surface water runoff from adjacent paved and soft landscaped areas runs directly into the swale trench watering the flora and fauna in the swale. The storm cell collects the larger volumes of rainwater from the buildings and paved areas.

The swale and storm cell are linked by ‘overflow’ pipes so that in the event of short term intense storms the swale is able to overflow into the attenuation trench below.

The soil investigation identified significant requirements for remediation including isolated areas of Hazardous waste. CampbellReith designed a remediation strategy across the site by 200-300mm, raising ground levels and an outline strategy for site treatment of waste soil before disposal off site was agreed. This achieved substantial savings compared to initial estimates. Detailed investigation and studies have been undertaken on ground gas generation and hydrocarbon presence in higher level ground water to mitigate the extent of protection measures.
