PERI’s entry, the ‘External Climbing Stair Tower’, is a collaborative effort between its technical specialists and sub-contractor, AJ Morrisroe. It was first used during the construction of Upper Riverside 1 & 2 (Greenwich Peninsula), as flexible access scaffolding was required to enable work to commence on the floors below, as well as providing operatives with secure temporary access points.
The solution comprises two strong off-the-shelf PERI products, a PERI UP access system and Rail-Guided Climbing System (RCS), which enables the whole system to climb via hydraulics, whilst being securely connected to the structure at all times.
Unlike typical access systems on the market that are installed from the ground up, the climbing cantilevered staircase can be installed at any height on a building, offering seamless integration and more flexibility than standard stair towers. It also reduces the number of scaffolding components used over the course of a project; fewer modules are required to meet the constructed height of the building. Sub-contractors also benefit from a decline in crane operation throughout this process.
