ALLTASK AND PSD DELIVER INNOVATIVE SOLUTIONS ON A40 FLYOVER PROJECT
Critical safety maintenance works to the A40 Westway Flyover at Shepherd’s Bush posed unique challenges for Alltask who worked with Prime Scaffold and Structural Designs Ltd to deliver innovative solutions which provide a compelling case study in engineering and design.
Working for their clients FM Conway, the first phase of the project involved Alltask building a Haki birdcage within the grounds of Imperial College London to provide stability and support for the foundational aspects of the project, ensuring safety and efficiency during construction.
Haki system scaffold was then used to build suspended access over the car park at Imperial College to allow it to continue to be used by the College throughout the duration of the works.
The completion of the scaffolding for the project will involve building suspended access over two Network Rail Lines – where the proximity of the scaffold to the active railway will present a unique set of challenges, with only approximately 500mm of clearance at the closest point to the trains - and a further bridged birdcage spanning a service road to an industrial site.
In addition to the technical challenges, Alltask were required to liaise closely with Imperial College, which remained operational throughout, to ensure minimal impact on their day-to-day operations. To help achieve this, Alltask adhered to a strict vehicle logging system and set delivery slots.
The suspended scaffold was constructed using Haki system scaffold and adopting their erect - ahead method, a pioneering creeping hanging style which allows for the erection of the scaffold while incorporating shear ties strategically installed to the underside of the underpass – an essential consideration for maintaining structural integrity and safety in such a dynamic environment.
It seems entirely appropriate that the innovative solutions delivered by Alltask and Prime Scaffold and Structural Designs Ltd took place in the grounds of Imperial College London - a world-leading university for science, technology and engineering.
While Alltask has a well-established and valued relationship with Haki, this project was the first time that this particular division of Alltask had used Haki for suspended scaffold – but they are adamant that it won’t be the last: “The entire project is testament to the power of collaboration, highlighting how effective teamwork among Alltask, PSD, and UKSSH is crucial to overcoming obstacles and achieving successful outcomes.
“From the outset UKSSH were on board and totally supportive of our efforts – from their unsurpassed knowledge and experience of Haki to their speed of response and willingness to help us achieve our exacting delivery schedules”.
