Summary Case Study:
ASOS Plc, Greater London House

Key Data:

• Project value £1.5m

• Retro-fit of FM Global HC-2 Sprinkler System to historic building

• 4,000+ sprinkler heads over six occupied floors and basement car park

• New pump house and 210m3 water tank 

• 1 dry and 15 wet isolating zone valves

• Complete installation service including hydraulic calculations and pump house architecture

• Interface with buildings’ fire alarm and security systems

• Principle designer, principle contractor and on-site management services provided

Our Role:

Following an FM Global Fire Risk report, the company were appointed as Fire Engineers to design, procure and install a sprinkler system and associated trade works for the protection of all ASOS assets. 

ASOS occupy the entire first, second and sixth floors, together with part of the lower ground, ground and fourth floors.  There are a number of other tenants currently occupying the building.

The company provided a fully hydraulically calculated design for statutory approval purposes, also for the client’s insurers approved FM Global. Full time site-management was provided to administer the CDM Regulations and ensure safe and incident free work throughout the installation period.

Challenges and Collaboration:

Greater London House is a ‘live’ building with multiple tenancies over 6 floors. ASOS’ occupancy comprises offices, open workspaces, film and photographic studios, café and canteen areas and a gymnasium.

Retro-fitting a comprehensive sprinkler system into such an environment requiring out-of-hours attendance to minimise disruption of business-as-usual; workspaces being cleaned and cleared of materials before each working day.

GLH is an iconic historical building requiring care and attention to the building fabric and internal architecture throughout the project.

Commitment to sustainability and the environment:

The company deliver design solutions based on the cornerstone of sustainability, environmental integrity, economic viability and social well-being.
