Address: Paddington, London
Client: European Land and Property Ltd / Laing Oâ€™Rourke
The Merchant Square development contrasts modern architecture with the canal boats in the Paddington Basin. At the center of this development is the Carmine building, where it is essential that its clean triangular lines are not spoilt by the building maintenance units.
Due to the design and shape of the building, three BMUs were required to access all the faÃ§ades. Rather than parking the BMUs on the skyline, they are withdrawn from the edge and then dropped behind the faÃ§ade by a lifting system capable of lifting the 9 ton building maintenance unit and its 2 ton carriage. Lenze was chosen to be our supply partner to supply the drive system complete with screw jacks.
Each BMU has a parking position where rails at 90 degrees to the faÃ§ade take its carriage some 7m back into the parking position. Each carriage is driven by inverter controlled geared motors, fitted with spring applied brakes, blowers to permit continuous operation at low speed and anti-condensation heaters, as the installation is often exposed to cold temperatures.
This vastly complicated projected was completed on target to achieve the client’s programme and cost expectations.
