Intro
Located in the heart of Westminster, 105 Victoria Street is a landmark construction project pushing the boundaries of vertical building efficiency and innovation. Central to this advancement is the bespoke Jumpform Rig Design, designed and coordinated by Finan Formworks Ltd working with the reputable Careys Group. Known for delivering tailored engineering solutions across the UK’s most ambitious developments, we were proud to bring both innovation and sustainability to this high-profile project.
Project Overview
The 105 Victoria Street development involves the design and deployment of a complex jumpform rig system for the building’s East and West Cores. Drawing from the firm’s previous experience on major high-rise sites such as One Leadenhall and Embankment Manchester, Finan Formworks was commissioned to provide a full rig solution built entirely from existing stock, ensuring both cost-efficiency and sustainable reuse of materials.
The project encompasses rigorous modelling, fabrication detailing, certification, and on-site operational support, all executed within a dynamic and demanding programme.
Innovations
What makes this project distinctive is the strategic reuse of previously deployed jumpform rig components. Finan Formworks’ engineering team carried out:
A comprehensive analysis of the One Leadenhall and Embankment rigs to match and maximise existing stock.
Identification of rig elements that could be reused with or without modification, significantly reducing fabrication time and material waste.
Integration of critical project-specific features, including:
- Precast stair installation compatibility with tailored hatch designs.
- A concrete pump and central mounting frame designed into the rig plan.
- A reconfigured trailing platform and dual stair access for improved on-site movement.
- Enlarged and repositioned access hatches for safer and more efficient access.
- Modifications ensuring crane rope clearances within 500mm tolerances.
Collaboration on the quality assessment and refurbishment of Alkus ply, to ensure shutter surfaces met aesthetic and performance standards.
