Client: British Land
Main Contractor: Lendlease
Initially working as Principal Contractor for new client British Land, A J Morrisroe & Sons Ltd was appointed for the reinforced concrete substructure package to the North East Quadrant Development, which formed part of the Regents Place masterplan in Autumn 2010.
The substructure works comprised the construction of the shared basement box to ground floor level, as well as the three reinforced concrete structural cores for the commercial buildings. Our works included: foundation and perimeter wall piling; a substantial muck shift of 35,000m², all below ground drainage; lightning protection; foundations; ground bearing slabs, steel sheet piling and propping to form the lower basement, retaining walls, single sided basement lining walls; suspended slabs and structural cores up to and including ground level.
We were subsequently appointed by Lendlease to continue with the superstructure element of these works bringing the combined package value to circa £25m and completed by spring 2012.
The superstructure reinforced concrete works to the residential and commercial buildings comprised four slipform cores, structural topping to the three steel frame structures, plus 25 and nine storey residential blocks. It also included a seven storey commercial building known as Brock Street. The main residential tower was constructed using slipform for both the core and Vierendeel walls at the slab edge. A five-storey perimeter safe screen was installed to provide a safe working environment for the reinforced concrete slab construction as well as Metsec stud walls, balconies and glazing.
Achieving the BREEAM ‘Excellent’ rating for both residential and commercial elements of the development was an essential requirement for British Land. AJ Morrisroe & Sons was able to support the attainment of key credits based on material selection, waste management, community engagement and energy usage.
