Passive fire protection for offices and commercial buildings
Office buildings change constantly. Tenants fit out and move on, IT and comms contractors run new cabling, mechanical upgrades cut through fire-rated walls and ceilings, and every one of those changes can break the compartmentation the building was designed with. TECS works for landlords, managing agents, facilities management companies and occupiers to find and fix those breaches and keep fire doors performing, without disrupting the people working in the building.
Most of our commercial work is in occupied buildings in central London and the business parks around the M25, M3, M4 and A1. We work floor by floor, out of hours where needed, and hand back each area clean and signed off so the building manager has nothing to explain the next morning.
Who is responsible
Under the Regulatory Reform (Fire Safety) Order 2005 the landlord or managing agent is usually the Responsible Person for the common parts and structure, while each tenant is responsible for its own demise. Fire doors on the landlord’s escape routes, riser doors and the fire stopping in shared risers and ceiling voids all sit with the landlord; doors and penetrations inside a tenant’s fit-out sit with the tenant. We record every item by location so each party can see what is theirs and what has been done. Our guide to fire safety responsibilities covers the detail.
Typical scope in a commercial building
Fire door inspection of every escape route, stair, lobby, riser and plant room door, with a pass, fail or advisory rating
Remedial repairs from the same visit where possible: closers, hinges, seals, latches, glazing, signage and hold-open devices
Compartmentation survey of risers, ceiling voids, service corridors and plant areas, including penetrations left by previous fit-outs
Fire stopping of cable trays, pipework, ductwork and linear joints with tested systems matched to the wall or floor type
New FD30 and FD60 doorsets for reception areas, stair cores and plant rooms, including glazed and acoustic specifications
Planned maintenance contracts across multi-site portfolios with one OneTrace account for the whole estate
Serviced and flexible workspace
Serviced office operators turn space over quickly and need compliance evidence that keeps pace. We inspect and repair across whole centres in a single programme, label each door and seal, and provide the operator with a record it can share with its own landlord and its clients.
Services commercial clients use most
Fire door inspections, fire door repairs, fire stopping, compartmentation surveys, fire door installation and planned maintenance.
Case studies
At 35 King Street, Covent Garden we combined fire door maintenance, a new FD30s doorset and compartmentation works in one central London building. At Regus Arlington Square in Bracknell we delivered Q-Mark fire stopping across an occupied serviced office building, and at Spaces Euston we carried out remedial fire stopping along escape routes, corridors and soffits.
Every door and seal recorded
Every door and penetration is recorded in OneTrace with photographs, location and product data, giving the Responsible Person and the fire risk assessor live evidence of compliance. Read how building works can break fire compartmentation for the most common causes we find in offices.
