Firestopping Takeoff Services: The Scope Everyone Forgets Until the Inspector Arrives

Firestopping Is a Measurable Scope, So We Measure It

Plenty of drywall bids carry firestopping as an allowance and hope. Then the inspection walk happens, the joint system the drawings referenced turns out to need spray on both sides, and the allowance evaporates. Our firestopping estimating services turn the scope into quantities: every rated wall's head-of-wall condition measured by linear foot, every penetration type counted where the documents show them, every perimeter condition at the slab edge quantified per detail.

• Head-of-wall fire joints by linear foot, per rating and deflection
• Bottom-of-wall and wall-to-wall joints where assemblies require
• Through-penetration firestop by type: pipe, conduit, cable, duct
• Fire-rated putty pads at electrical boxes in rated walls
• Perimeter fire containment at curtain wall and slab edges
• Fire caulk, spray, sealant and mineral wool safing quantities
• Listed system references carried on every line item
• Smoke and acoustical sealant scopes kept on separate lines

Quantified to the Listed Systems

Firestopping only passes inspection when the installed condition matches a tested and listed system, so our takeoff references the systems your drawings call out and quantifies the materials those listings require. Where the documents are silent on the system, we quantify the conditions and flag the selection as an open item, so you can carry a qualified number instead of a blind one.

Who Orders This Takeoff

Drywall subcontractors who carry firestopping inside their package. Specialty firestop contractors bidding the scope standalone. GCs who need to know whether the sub numbers actually cover the rated construction on the job.
