J S Wright has won a £17 million contract for the latest phase of the London Dock development.
The company was contracted by St George to install the mechanical and electrical systems for all 359 new-build apartments within Saffron Wharf.
The block of mixed-tenure apartments is part of a master plan for 1,800 new homes and 180,000ft2 of commercial space on the 15-acre site of the former News International printworks.
J S Wright will play a major role in connecting the existing phases of London Dock by extending its district heating system and mains cold water service to serve Saffron Wharf and future phases.
Works will consist of installing a low temperature hot water (LTHW) distribution system, including a heating substation, and a boosted cold water (BCW) plant room with distribution network, along with a CAT5 cold water service, soil and waste, above ground drainage, and rainwater services.
J S Wright will also equip the site with the fire sprinklers to serve the apartments and commercial areas, as well as extend the hydrant main and wet risers to serve all the cores.
The mechanical shell and core package also involves installing natural and automatic smoke ventilation systems for the car park, refuse bin stores and commercial units via a ventilation substation, and fitting a variable refrigerant flow (VRF) system for heating and cooling common areas.
The electrical infrastructure work will include installing mains and submains distribution and containment systems, and external and internal lighting. Fire alarms, access control and CCTV, TV, data and phone systems, and electric vehicle chargers are also part of the package.
The homes will in turn be fitted out by J S Wright with hot and cold-water services, heat recovery ventilation, radiators and underfloor heating and cooling services via VRF fan coil units.
J S Wright will also provide the homes with all their electrical systems including lighting, small power, fire alarms and door entry systems.
Work on site is scheduled to start in late 2022, with completion of the contract due in early 2025.
