Commercial fire stopping sealed to the compartment, not a tub of mastic
Fire stopping fails where later trades have punched the wall. We record the opening, the services through it, and the seal that belongs there.
What this commercial job is
A package can be a survey only, or survey plus the seals you approve. We do not blanket a riser with the wrong product because it was on the van.
Photos and locations go back to the FRA actions. If a penetration needs a specialist seal or a builder to remake the substrate, that is written as such.

Questions facilities teams ask
Do you certify the whole building as compartmented?
No. We record the openings we were asked to survey or seal.
Can you work above a live office?
Often out of hours. Dust, access and tenant notice are part of the quote.
Is mastic always enough?
No. Cables, pipes and dampers need the detail that matches the wall.
