4 - 6 Stanhope Gate Erith was employed by Clivedale Ventures to undertake the demolition of 4-6 Stanhope Gate, paving the way for the new Mayfair Park Residences. The site encompassed a collection of office buildings, a bank located within the Mayfair conservation area, as well as two 17th century Georgian façades that were to be retained and closely monitored throughout the duration of the works. Furthermore, the site sat adjacent to the luxury 5 star hotel; 45 Park Lane, notably part of the exclusive Dorchester Collection. Due to the sensitive and elegant nature of the location, noise, dust and vibration controls were implemented to mitigate the potential for any nuisances caused by work activities. The works undertaken included the following activities; Furthermore, the asbestos removal phase of works involved the removal of amosite and crocidolite to beams. An initial bulk strip was then followed by a fine clean/quill to deliver the steelwork to an acceptably clean standard, this process took circa 6 months. The structure was completely stripped of all off non-structural elements, with arisings segregated into individual waste streams for recycling. Piling works incorporated systematic coring, propping of ground floor slabs, cutting out basement slabs and then piling from the ground floor level within headroom confines of 3.5m. Piles were 600mm in diameter to a depth of 28 meters. Steelwork was installed to needle the footings with the associated frame erected using a self-erecting tower crane. This was designed to avoid pile clashes in phase 2 basement formation works and to permit an excavation sequence that allowed for the ground to be removed and leave the façade on piles. The structural demolition was undertaken using a controlled top-down demolition method where mini machines were lifted to the highest point by crane. The building was then systematically systematically taken down using top-down demolition techniques. Upon successful completion of the work the client placed a basement order with Erith, in light of the demolition works undertaken at 4-6 Stanhope Gate. • Site set up • Hazardous material removal • Soft strip • Temporary works design for retaining the two façades (inclusive of AIP and party wall awards) • Engineering assessments of pile settlements • Building uplifts for the purpose of pile design • Diamond cutting • Concrete repairs • Asbestos removal • Party wall demolition • Temporary works • Stonework salvage • Scaffolding • Waterproofing • Insulation of party walls • Structural demolition and removal of materials Demolition
