Frankham’s M&E consultants were appointed to design, procure and contract manage the installation of permanent chillers on the roof of this occupied building in order to provide a highly efficient reliable cooling system for WCC’s staff and commercial tenants.

The project resulted in elimination of potential risks associated with Evaporative Cooling towers and provide a significant reduction in the building carbon footprint and a significant reduction in ongoing energy costs.

Frankham’s M&E consultants and the contractor carefully managed the project in collaboration with Westminster City Council and Land Securities to minimise any inconvenience to City Hall staff, visitors and local residential occupants and so this major phase of the project was successfully undertaken overnight at a Bank Holiday weekend.

Technical background:

Frankham M&E managed the removal of the existing chillers that have previously mechanically failed and temporary chillers were installed. Frankham then designed, budgeted and procured a scheme to:

  • Remove the existing decommissioned cooling towers.
  • Install structural steelwork to support the fan units off the building’s main structure at roof level.
  • Install and commission chilled water system of 2.25MW capacity on the existing roof space of City Hall.
  • Install a new electrical supply and panel to supply the new chiller equipment.
  • Commission, load test and run the new plant.

This project was carefully designed and delivered around the constraints of working in an occupied building, where the existing services and access could not be compromised with construction access and materials logistics management, in and out of the building and immediate surroundings planned with stakeholders.
