Fire rated partitions and facade for commercial offices

An office tower has six or seven different rated conditions in it. The argument here is not about any one of them — it is about specifying all of them once.

Count the rated conditions before counting the products

A typical Indian office tower has a lift lobby screen at every level, a core wall around the stair and services, a stair enclosure, a refuge area, a tenant demise line that changes every time a floor is re-let, and a facade with a rated perimeter condition. That is six or seven different assemblies, usually procured as three or four packages from three or four manufacturers.

Each of those packages brings its own profile family, its own connectors, its own test evidence, its own fabricator and its own submittal. The junctions between them are detailed on site. The coordination cost of that is real and it lands on the main contractor’s programme, not on the product schedule anyone compared at tender.

Specifying one cold-rolled steel system across all of them collapses that: one profile family, one face width, one set of details, one fabricator who has cut it before. It is a procurement argument rather than a product one, and it is the argument that actually wins office work.

The refuge area is where the code bites hardest

The National Building Code requires refuge areas at defined intervals in tall buildings, and a refuge is a place people are asked to wait rather than pass through. That makes it the one condition in an office where the occupants are stationary against the boundary — the same situation a hospital compartment is in, and the same reason the insulation figure deserves to be read rather than assumed.

FT-CW measured 42 minutes of insulation, stated on this site beside the integrity figures — because a refuge specification is one that should be checked against the report behind it, not assumed from the classification alone.

One platform is also one conversation at the facade

The lift lobby screen and the facade are usually different trades who meet at the slab edge. Where both are the same steel system, the perimeter condition is a detail inside one manufacturer’s scope instead of an interface between two — and if a floor is re-let and a demise line moves, the new screen is the system already on site rather than a fourth supplier.

Steel systems made by Firetec. The frame is specified together with the glass it holds, rather than assembled from whatever is available — which on a rated assembly is the difference between two components that passed and one that works.

What this sector specifies

Classifications are what the test reports record. Where older marketing material runs ahead of a report, this site prints the report.

BR-Shield

Bullet Resistant Systems

BR6FB6

Cold-rolled steel systems with glass in the system, as door systems, fixed partitions and cap curtain wall. Tested to EN 1063 BR6 and EN 1522 FB6 - partial compliance.

Fire Rated Curtain Wall

E120EI30EW120

Mullion and transom curtain wall on a slim 45-60 mm face. The curtain wall was intact on both faces at the end of a two-hour test.

FT-PD

Fire Rated Doors & Partitions

E120EI30EW120

Steel framing for building entrances, lift lobbies, server rooms and corridors. A two-hour fire rating - 120 minutes integrity and 120 minutes radiation control - classified E120 / EI30 / EW120.
