Complex Stair Tower Installation Completed at Whitlingham STC
Location: Whitlingham STC
Project Value: £321,000
Project Overview
Steelway carried out the design, fabrication and installation of a central stair tower positioned between two storage tanks at Whitlingham STC.
This project was a challenging but rewarding build that required close teamwork and careful planning. The task was to design and install a central stair tower between two existing storage tanks, with the added complexity of supporting a stainless-steel limpet chamber and providing safe access for ongoing maintenance. To achieve this, the works had to be phased and coordinated with other trades on site, making collaboration key to the project’s success.
From the outset, Steelway was heavily involved in shaping the design. We looked after everything from the early layout and detailing through to ensuring consistency across different design packages and coordination meetings. The aim throughout was simple: create a safe, practical, and durable solution that worked within the tight site conditions.
How the Project Came Together
The build took shape in three phases. First, the lower stair tower was constructed, designed with enough room to house all the M&E services within a very tight footprint. Getting the details right at this stage meant avoiding clashes later on and keeping the project moving.
Once that was in place, work moved to the upper stair tower and the installation of the limpet chamber. This part called for real precision, as the chamber had to align perfectly with the existing structure. Finally, the top platform and roof access were added, complete with guardrails designed for both safety and a consistent finish across the whole system.
Alongside the main works, a smaller but vital feature was added: the De-Gas Pots Platform at the first level of the stair tower. This platform was carefully detailed to ensure it was strong, adaptable, and safe, with well-considered stairs, handrails and connection points that would make long-term use straightforward for site teams.
"The Whitlingham Stair Tower was a technically demanding project that required careful sequencing of structural and M&E works, along with close coordination between multiple disciplines. Our team maintained consistency across all design stages, from spatial planning to final detailing, ensuring the stair tower and associated platforms were delivered as a safe, fully integrated and functional system tailored to the site’s unique challenges."
