Construction of a high specification commercial office building in central London, adjacent to Aldgate Tower.
Located on the edge of the City of London, this 18-storey commercial office building, adjacent to Aldgate Tower, represents phase two of a prestigious Aldgate redevelopment scheme and provides c.325,000 square feet of open-plan office space. The building was developed as an open plan architectural space for commercial letting with two of the lower levels being designed as public areas. Overall, the building adopts a contemporary office feel with exposed soffits throughout. Much of the completed steel frame will also be left exposed and so significant care has been taken with the connection details.
The Group's scope included the supply and erection of beam and column steelwork together with metal decking, fire protection, stairs and open type flooring. The Group provided decorative fire protected columns and beams with an open architectural soffit, with the underside of the metal decking on display along with two steel staircases spanning the entire height of the building. The ground floor is a double-height space, accommodating the entrance lobby, while the first floor, which is set back to create this large space, accommodates a cantilevering walkway overlooking the entrance. Large portions of the floor are suspended from the underside of the second floor via a series of Macalloy hangers and steel plate hangars to form recessed low level façades.
The nature and location of the project presented additional challenges. Working so close to an active airport meant that site operations were conducted at unusual hours in order to prevent the landing air traffic from being disrupted by the cranes needed to position the trusses. These trusses also needed to have tight tolerances over large distances in order to properly install the crane gantry beams, with the use of temporary support towers necessitating a very specific order for their installation. The project also called for the use of four different paint systems, requiring close coordination and tracking from the drawing office through to production. Despite the challenges, the site programme was completed to the original schedule.
