The work is for Willmott Partnership Homes’ £39m scheme for Royal Holloway, University of London, delivered as part of the Scape Major Works Framework.
The scheme, which has been designed by Stride Treglown in Bristol, will form the cornerstone of the university’s North Campus in Egham, Surrey. There will be 621 student bedrooms across 56 townhouses, along with an amenity block with a lecture theatre and teaching spaces. It will enable the university to offer a residential place to all first-year undergraduates.
The BREEAM Excellent scheme will see LJJ install a new district heating system in the new amenity block linked to the university wide building management system. A combined heat and power unit will be the primary energy source, delivering 90kW of thermal energy and 49kW of electrical energy. The system will also include three gas-fired boiler with a total output of 1,250kW for boost and back up. LJJ will install a pre-insulated district heating main that will run under the development to deliver heat and domestic hot water to the townhouses via a 300 litre heating interface unit in each building.
For the cold water supply, LJJ will install a cold water storage tank of 30,000 litre capacity together with a booster system.
LJJ will also install a mechanical ventilation system with heat recovery in the roof space of each town house to feed the supply and extract for all bathrooms, corridors, kitchens and communal areas.
The electrical installation will involve provision of a new HV network, including a new transformer and three HV ring main units. An LV switch room in the amenity block will then supply four feeder pillars around the development which will supply the townhouses and external services, including CCTV and street lighting.
LJJ will install a mix of LED and fluorescent lighting throughout the scheme, with PIR presence detection in corridors and amenity block toilets. The electrical installation also includes access control for all main entrances, student bedrooms and the amenity block, 20 CCTV cameras and a fire alarm that will release all doors in the event of a fire.
The company will also be responsible for a Cat 6 data installation, including fibre networks connected to individual cabinets in each town house and the amenity block, providing site-wide wifi.
Willmott Partnership Homes design manager Andrew Vittery said: “This is an ambitious project to construct 56 town houses with a business-critical completion by the start of the academic year in September 2017. Our response has been to include a significant modular element to the build and we are confident that LJJ’s experience of major university schemes will help to ensure that the building services elements of this project are similarly focused on fast and high-quality delivery.”
