About The Project:

99-101 Queen Victoria Street was the former Salvation Army Building. It was demolished to make way for two independent buildings.

One building was made into the Salvation Army International Headquarters while the other was an 80,000 square foot speculation office.

The site occupied a prominent location in the heart of the City of London within close proximity to St. Paul’s Cathedral, The Millennium Bridge and the Bank of England.

The building which houses the Salvation Army has full height glazing with a layered and engineered look to the front elevation commanding a dominant street presence.

The lower three floors comprises a café, board room, meetings rooms, and executive offices, while the upper three floors are open plan office space.

Key features:

  • Feature lighting to accentuate and compliment the architectural element of the building, including cold cathode and colour changing LED lighting technologies
  • Office Floor Plate Lighting - high quality lighting with latest technology louvers and sympathetically designed the lighting schemes to comply with Lighting Guide 3
  • Office Lighting Scheme - connected via an addressable LON Works Lighting Control System

Due to the location of the project all plant and materials had to arrive and be craned into position at set times, often out of hours, for safety reasons. These limitations, together with time constraints, labour resources and high quality specifications, meant that the decision was made to prefabricate the chilled water and heating systems.

Over a 16 week period approximately 400 6m long, 4 pipe prefabricated skids were delivered to site. Each of these skids contained two chilled water and two low pressure hot water pipe systems, complete with all the necessary valves, strainers, commissioning stations, expansion devices, terminal devices and insulation.

The use of prefabrication enabled us to control materials, labour and health and safety issues in a logical, economic and pre planned manner. It gave us the confidence and ability to meet site demands and the rigorous quality assurances that the client demanded.

The site was further complicated by low noise specifications for external plant and the St. Paul’s Cathedral line of sight stipulations enforced by Building Control and The City of London. Our design team had to consider both these pre-requisites when selecting air handling plant and outdoor air cooled packaged chillers.

Mechanical Scope:

  • 2400KW gas fired boiler plant
  • 1800KW roof mounted air cooled packaged chilled water plant
  • 500 airside 4 pipe fan coil units
  • Building Management System
  • Tanked and hot water services
  • Public health and drainage
  • Supply and extract air handling plant and ducted systems
