Pomeroy M+E contractor makes a big splash on City of London project…
Working closely with main contractor Graham, Michael Nugent Ltd provided a complex MEP installation for the Laser House redevelopment project in London’s fashionable Clerkenwell district.
Formally a printing press and gin distillery, the 1960’s property has been transformed into a new creative hub, following a £15m redevelopment programme. Headquartered in Pomeroy, Michael Nugent Ltd has a wealth of commercial experience working with Graham, and were delighted to have worked on the 88,000 sq ft, project together.
Mechanical
Michael Nugent Ltd were asked to develop, design and install the mechanical services suitable and with respect to an open plan, CAT A, office design set within an existing heritage building. The main design objectives were to accommodate a spilt tenancy arrangement on each floor level, while routing exposed services through the building and achieving the selected fit-out strategy.
The mechanical installation comprised of the following services: LTHW heating system, mains water services, boosted cold water services, domestic hot water services, water treatment system, gas installation, fresh and exhaust air ventilation systems, smoke control ventilation, VRF air conditioning, under-floor air conditioning and automatic controls and building management system.
One of the main challenges Michael Nugent Ltd had to overcome was to install and route their services through the existing building due to the limited-service zones and the client’s requirement for an open plan fit-out strategy. This was facilitated by working in collaboration with its BIM team to ensure that all services were fully co-ordinated to meet the client’s vision and expectations.
On this project Michael Nugent Ltd installed under-floor air conditioning systems on the main tenant floors, which allowed for the plenum beneath the raised access floors to be used as ventilation zones instead of traditional ceiling-based air conditioning units. This enabled its design team to eliminate all ceiling-based ductwork and services to maximise ceiling heights within the open plan office spaces. Under-floor air conditioning systems will improve thermal comfort within the building by allowing individual occupants to control their local thermal environment while also improving efficiency, indoor air quality and reducing building life-cycle costs.
Electrical
Michael Nugent installed a completely new LV distribution system throughout the building from the basement up to fifth roof plant level. The general and emergency lighting package is Dali controlled in most areas with automatic detection utilised to ensure lighting only operated on presence detection.
Power and data requirements included fibre backbone to tenant spaces. The fire alarm installation uses an addressable system with under-floor detection and air aspiration system installed where appropriate.
Security and access control systems were installed allowing monitoring and limitation to access throughout the building. Also included was a lightning protection system.
As a large part of the building was existing, the electrical team had to work closely with the main contractor to co-ordinate systems keeping inline with architect expectations. Services were mostly exposed so all contractors adapted attention to detail
Lighting was designed with LED and daylight dimming where natural light wasn’t available. Auto detection of lights will ensure limited operating time.
Commenting on the completed project, Mechanical Project Manager, Sean Mallon said, “Being part of the Laser House project from start to finish has been very satisfying. It is great to see the project through from commencement, the commissioning stage and finally, completion. I have gained great new skills and knowledge by overcoming the complex installation of under-floor air conditioning systems.”
