VolkerFitzpatrick has begun work on an £11M design and build contract for a complex refurbishment job in London’s West End.
The work at Bentinck Street, for client Howard de Walden Estates, involves the demolition of the existing structure while retaining the façade at the front of the office and apartment buildings
Existing features such as the roof slates, chimney pots and brickwork are to be removed and reinstated into the new construction. The façade will be temporarily supported during the demolition of the existing structure and linked to the construction of the new structure behind. The façade support system has been designed around the use of the existing coal holes, thereby minimising disruption to the existing utility services currently located beneath the pavement and carriageway.
The sub-structure works include major underpinning to the existing structure using 200, 1m by 2m deep pins.The steel superstructure work follows on from this. The envelope will comprise a mixture of brickwork, structural glazing and permanent sunshading techniques to the rear elevation.
The project has been designed to achieve a BREEAM rating of Excellent and incorporates sustainable features such as ground source heat pumps, photovoltaic roof slates, green roof and solar heating to the apartments. The works are expected to last 80 weeks until May 2013.
