The project involved cutting out and demolishing the internal components of an existing Air Handling Unit (AHU). This process included the careful removal of coils, fans, and internal walls to ensure safe disposal. Following the demolition, new components were installed to replace the old coils, fans, and walls, restoring the AHU to a fully functional state.

A total of three crane lifts were required for the project to facilitate the removal of old materials and the installation of new equipment. These lifts were essential for safely transporting heavy and bulky items to and from the site while minimising disruption to surrounding areas. One of the crane lifts was conducted at night to reduce interference with ongoing operations and to take advantage of less crowded conditions. This nighttime operation involved careful coordination and additional safety measures to ensure efficient and safe execution in low-light conditions.

The project also included a changeover of the AHU fans, which required precise handling. The task involved disconnecting the old fans, installing new ones, and ensuring proper calibration and alignment for optimal performance.

Gantry systems were set up to lift equipment and materials through existing shafts within the building. This approach was chosen to avoid altering or damaging external walls, allowing for the efficient movement of heavy gear while preserving the building's structural integrity and exterior.
