As a former spice warehouse 9 Devonshire Square is based in between the City and Shoreditch. Now home to a variety of contemporary co-working spaces the building attracts business, retail units and restaurants due to its striking architecture, impressive glass ceiling and bright and airy space.
AD Mechanical were responsible for the Mechanical design and construction of new mechanical systems to floors 1,2,3 and 5. The scope of works included the design, co-ordination, installation, test and commissioning of:
- Foul drainage above ground pipework to serve the new sanitary appliances and other drainage outlets. All existing cast iron drainage pipework was removed and replaced with new pipework.
- Replacement of hot and cold-water system in order to receive and convey without waste, misuse, undue consumption or contamination.
- Low temperature hot water heating.
- Primary and secondary cooling distribution to generate and distribute chilled water to serve cooling emitters to maintain the cooling design temperatures in each space and satisfy other cooling loads in the building.
- Mechanical ventilation that supplies filtered air to and extract vitiated air from the Cat A open planned offices.
- Toilet extract ventilation to ventilate toilet areas, showers and changing rooms.
The biggest challenge was to overcome was constructing an AHU in a very small area. The AHU was flat packed and bought into the plantroom through a single door and rebuilt in stages. We employed a specialist lift and shift company to aid with the logistics. The project required a careful coordinated traffic management plan to allow for deliveries, this included permission for a Temporary Traffic Regulation order (TTRO). There was also a detailed confined space task specific risk and method statement to allow for connections above the AHU in a restrictive area.
AD Mechanical were responsible for installing under floor air conditioning. The UFAC system makes use of the plenum beneath a raised access floor to create the air ventilation zone eliminating the need for ceiling-based services and associated duct and pipework.
The project was a yearlong programme which commenced in December 2021 and was handed over in December 2022.
During the project, our Mechanical supervisor Ryan Gill received acknowledgement for being employee of the month. He was chosen due to his dedication, hard work and attention to consistently delivering high health and safety standards.
