Air handling unit manufacturer Barkell has supplied five bespoke AHUs for a major refurbishment project at Canary Wharf in London.
10 South Colonnade was one of the original towers constructed on the Canary Wharf estate in the early 1990s, to the the south west of the main tower and Canary Wharf DLR station.
M&E contractor Bancroft was selected for the execution of the project along with Aecom as consulting engineers from the design phase through to practical completion and handover.
Barkell was chosen to supply replacement air handling units and, as this was a refurbishment of an older building, there were space and access restrictions which made it challenging to comply with Building Regulations Part L and the ErP (Energy-related Products Directive 2009/125/EC).
To overcome this, Barkell designed and supplied the AHUs in flat-pack form and they were built on site by Barkell engineers.
Steve Lockwood, principal engineer, Aecom, said: "The main issues on this project were fitting the AHUs in tight areas and late change requirements. However, Barkell overcame these by putting forward multiple configuration options during the design phase, and adapting to updated requirements.
"With limited access routes to the created plant rooms, Barkell’s ability to construct on site was also very important on this project.
"Overall, we were very impressed with the build quality, and all units commissioned have had no issues in terms of meeting design performance.”
