Big Foot Systems has supplied rooftop plant support on a new commercial office building near King's Cross station in central London.
The split-level project used a range of non-penetrative frames including Custom Safe Access systems, Bespoke Frames, Custom HD Frames, HD Cubes and Custom HD Supports to provide safe access and support air handling units, chillers and high level pipes.
Nathan Wood, Site Engineer at Big Foot Systems, said: “The size and complexity of this project proved to be a real challenge. To design a system with over 500 different parts to fit in an unusual space meant we had to be innovative and think outside our normal design practices to provide a solution that worked well. Also, due to the time constraints, it was critical to provide these quickly and efficiently.”
On the project the roof was split into two levels, level 9 and level 11. The supports for level 9 included: a custom HD frame supporting an air handling unit (AHU) weighing over 7800kg, custom access to service the AHU, and integrated access and pipe support for seven large volume water pipes at 4m above the roof level. Meanwhile, supports for level 11 included: HD Cubes supporting four chillers weighing 5,700kg each, two bespoke frames supporting air handling units weighing 6,500kg each, a custom HD support with integrated access for a 15,750kg generator and over 100m² of custom safe access. The deliveries of the frames were staggered over six months to allow the different services to be co-ordinated with Big Foot Systems, with full assistance offered to aid the install by the site team.
