Decommission, recover refrigerant, remove and safely dispose of 50 existing ceiling cassette units and eight external condensers, then replace with a new equivalent. The works will involve the removal of the existing ceiling cassette units and associated grid ceilings around each unit. While these works are being undertaken, the nine wall-mounted controllers must also be replaced. In addition, a new central control unit will be installed. While these works are undertaken, part of the floorplate will be cordoned off and furniture removed in local areas.
The contractor will likely use mobile scaffolding towers and lifting equipment during these works, which can be brought onto the floor via the designated goods lift. It is expected that all deliveries and removal of equipment will be carried out during office hours. Likewise, the main works, such as replacing the units on a point-for-point basis, can be undertaken during office hours with close liaison with the appropriate tenants. The external units can be replaced again on a point-for-point basis while the indoor units are also being replaced. It is not expected that the external works will cause any disruption to the business. The contractor will provide a detailed location-by-location program so that a plan of execution can be developed and communicated.
