BURY-based ductwork giants Senior Hargreaves have just completed the second phase of an important contract.

The company has finished the second of two express ductwork projects at London's Canary Wharf for international investment bankers Credit Suisse First Boston.

Two buildings comprising 270,000 sq ft of high quality office space and computing suites have been fitted out in record time.

The first building has 200,000 sq ft over 10 floors. This was handed over after a 19 week fit-out period.

Senior Hargreaves is the UK's largest specialist ductwork contractor and one of only a few companies able to undertake work of this scale and complexity. They have supplied medium pressure acoustically lagged environmental ductwork and installed more than 600 Trox fan assisted variable air volume terminal units.

In addition, a small quantity of fire resistant ductwork for a fire-protected computing suite has been installed.

The building environment is under the control of a building management system. This controls the plant to deliver approximately conditioned air via the Senior Hargreaves ductwork.

To meet the strict schedules for opening, Senior Hargreaves worked in close collaboration with other fit-out trades.

Ductwork sections, fittings and accessories were delivered to site on a just-in-time basis.

Sections were pre-fabricated, wherever possible, to speed and simplify on-site handling and installation.

The success of the first building led directly to Credit Suisse First Boston awarding the smaller, technically similar 700,000 sq ft West Ferry Circus project to the same elite team.

Senior Hargreaves worked under direct contract for fit-out contractors Bovis Lend Lease.

Architects for the project were Gensler and Associates while engineering systems were designed by Hilson Moran Partnership with Arup Project Management acting as planners and contract administrators.
