A significant construction project at 2 Finsbury Avenue in London is making strides with the aid of advanced propping systems. The development, situated within the Broadgate campus, involves the erection of two towers, soaring 37 and 23 storeys respectively, linked by an 18-storey podium. Mabey Hire’s Mass 25 and Mass 50 propping systems play a crucial role in supporting the deep basement excavation required for the project, serving as pivotal components of the construction methodology.
The intricate design of the development necessitated the inclusion of a substantial secant piled retaining wall, designed and implemented by Cementation Skanska. The retaining wall extends to a considerable depth of 38 metres and is supplemented by bearing piles and plunge columns to facilitate a top-down construction approach. To achieve excavation of the basement levels, two stages of finger props were strategically connected to king posts within the secant wall piles. As asserted by Chris Roberts from Cementation Skanska, Mabey Hire’s extensive range of temporary propping equipment was ideally suited to meet the complex demands of the project.
In particular, the Mass 25 and Mass 50 props have been employed in various lengths, tailored to the unique specifications of the project’s structural support needs. The Mass 25 prop is capable of supporting up to 340kN on a single leg, while the Mass 50 can endure loads as high as 600kN. Given the substantial size and scope of the development’s substructure, expected loads on the temporary works equipment were estimated to reach up to 550kN, necessitating robust and reliable support systems.
Mabey Hire’s acquisition by Peri, a German formwork and scaffold manufacturer, has enhanced its capacity to supply such critical infrastructure solutions. The enduring partnership between Mabey Hire and Cementation Skanska underscores the strategic integration of expertise and cutting-edge technology in civil engineering projects. The 2 Finsbury Avenue project is anticipated to reach completion by 2027, promising to offer a new focal point for both commercial and communal activities, thereby contributing to the ongoing transformation of the Broadgate area.
The integration of Mabey Hire’s propping systems marks a significant contribution to the ambitious 2 Finsbury Avenue development, setting new standards in construction support technology.
