This project included the full ‘Design and Build’ of brand new LTHW heating and domestic water plant services to the toilet cores of a fully refurbished 10 storey office building in the heart of the City of London.

The initial 26-week design period was utilised for feasibility studies/design proposals, plant and distribution calculations, including technical submissions and schematic/distribution drawings for approval/sign off by the MEP Consulting Engineers. Working closely with all parties, the design changed and progressed from the initial client liaison and continuously throughout the project.

This was a sub-contract project working alongside other M&E contractors and under the instruction of a Principal Contractor. Close management, coordination and programming with all parties was continuously vital for the successful completion of this project.
