BMS and HVAC Plant Upgrade at Marks & Spencer Head Office

The Opportunity

The building environmental conditions were poor, and was affecting staff wellness. This was attributed to an aged and faulty BMS and issues with the major plant.

The Solution

The team at adi Intelligent Buildings completed a major BMS and HVAC upgrade for Marks & Spencer at its London HQ, Waterside House, located in Paddington. The project was eight months in duration with adi Intelligent Buildings appointed as Principal Contractor under CDM regulations.

Much of the work was to the live office floor areas of the building which had to be carefully planned to take place over weekends, and during this phase, seven day working had to be introduced for a period of 21 weeks. Each floor worked on had to be cleaned and ready for M&S operations to resume every Monday morning by 6am - a challenge met by our onsite team which averaged around 25 operatives each weekend. These included electricians, pipefitters, commissioning engineers, ceiling fixers, floor fixers, porters and cleaners.

The base contract included the upgrade of 19 existing control panels and the installation of 42 outstation panels, associated controls cabling, and the exchange of circa 900 cooling and heating valves, a new comms network, new CHW supply pipework and numerous plant integration works. During the project, we highlighted several legacy plant issues throughout the building, and these were added to the adi scope by M&S as variations and rectified within the works programme period.

Additional works included upgrades to the chillers, air handling units and smoke damper systems to name just a few. The project was led by adi Intelligent Building but was an adi Group collaboration project which included adi Climate Systems and adi Environmental.

The Benefits

Because of the BMS and HVAC plant upgrade, this resulted in better environmental conditions for staff.
