OAG were contracted by Sir Robert McAlpine Ltd to carry out the installation of external glazing, doors, cladding and canopy as part of the refurbishment of 425 Oxford Street London. The lower levels of the building were to be retail space and the new flagship store for Adidas.
The works comprised of design, manufacture and installation of double storey height, 6-metre-high facade external glazing to the retail space, supported on a bespoke laser cut steel box section framing system designed and engineered by OAG specifically for the project. Elsewhere OAG installed bespoke powered automatic frameless glass double doors to the main entrance office space with powered bifold security gates for night-time/out of hours security, together with a bespoke entrance canopy with bronze anodised aluminium soffit, flank and fascia panels. We were also responsible for the design and install of both fire-rated and non-fire rated PPC finished steel window systems to the upper levels and external security doors to various locations around the building.
The upper levels of the building remained fully occupied throughout the refurbishment requiring restrictions on noisy working which needed to be accommodated within the OAG programme. As a requirement of the Westminster local authority, the retail glazing installation to three elevations of the building including the main Oxford Street pedestrian thoroughfare, was required to be carried out over a continuous series of night working, commencing at 10pm each evening. The huge high-performance double-glazed units measuring up to 6 metres x 2.6 metres and each weighing 1000kg, were delivered to site at the start of each night-time shift manoeuvred into and installed using a mini crane. Following completion of each glazing shift all plant materials needed to be removed prior to 6am each morning.
Following the design phase, OAG commenced work on site during early August 2018 and the works were completed April 2019 with final client handover in June 2019.
