Fireproofing estimation plays a pivotal role in construction cost planning, especially in compliance-heavy regions like New York City. With stringent safety codes, varying material systems, and a mix of union and non-union labor rates, fireproofing must be approached as a data-driven process—not a guessing game.
At True Bid Data, we emphasize structured fireproofing estimation workflows that integrate with digital takeoffs, CSI formatting, and NYC-specific construction compliance layers. Whether you’re bidding for a public school under SCA or a private residential tower in Brooklyn, fireproofing can be a major variable in your bottom line.
Understanding Fireproofing Scope
Fireproofing typically falls under Division 07 – Thermal and Moisture Protection, often classified as:
- Spray-applied fire-resistive material (SFRM)
- Intumescent coatings (thin-film paint systems)
- Rigid board fireproofing
- Concrete encasement (rare in modern NYC projects)
Each system has different installation rates, coverage values, inspection protocols, and material waste factors. Fireproofing estimation should be tied directly to structural steel takeoffs, as it’s usually applied over beams, girders, and deck slabs.
How We Estimate Fireproofing
A professional fireproofing estimate requires more than surface area measurements. Here’s how our digital-first approach works:
Steel Shape Matching
We start by correlating fireproofing with beam and column schedules (e.g., W12x26, HSS, C-channels). Each shape requires a different coverage rate and thickness.
UL Design References
Most commercial projects in New York City require UL-rated assemblies. We tie your fireproofing scope to UL designs (like X701 or N752) for accurate thicknesses and inspection compliance.
Thickness-Based Quantities
Depending on fire ratings (1-hour, 2-hour, 3-hour), SFRM thickness may vary from 0.75″ to over 2″. Our takeoffs include zones by fire rating and account for loading and ventilation factors.
Access Conditions
Horizontal vs. vertical application rates affect labor productivity. We apply different crew productivity factors for:
- Overhead spraying (steel decks)
- Confined spaces (elevator shafts)
- Multi-phase buildings (with elevation constraints)
Key Data Points in NYC Fireproofing Estimation
New York City’s code enforcement and agency review protocols introduce unique variables to fireproofing estimates. At True Bid Data, we track the following:
- DOB-mandated UL systems in high-rise construction
- Inspection frequency and access (scaffolding, aerial lifts)
- Special coatings for exposed intumescent finishes
- Prevailing wage impact for union subcontractors
- Material testing and certificate submittals
Fireproofing in Government Projects: SCA, NYCHA, and OGS
If you’re bidding for public work in New York State, your fireproofing scope needs to reflect bid form clarity and regulatory alignment. Here’s how we handle major agency nuances:
- SCA: Requires division-level cost breakdowns with UL design citations and additive alternates (e.g., 3-hour rating upgrade).
- NYCHA: Typically involves rehab work, where fireproofing may need to be patched or inspected for code compliance.
- OGS/DASNY/SUNY: Often include exposed intumescent fireproofing in educational or healthcare facilities, which carry different finishes and cost implications.
How Fireproofing Affects Bid Competitiveness
Estimating fireproofing too conservatively leads to:
- Overpricing due to excessive material and labor buffers
- Missed alternates or scope clarifications
- Non-compliance with NYC agency submittal expectations
On the flip side, underestimating fireproofing results in:
- Change orders due to unanticipated thickness or system shifts
- Failed inspections or remedial work
- Eroded margins, especially on tight bid caps
With True Bid Data, we integrate quantity takeoffs with historical NYC project benchmarks, agency mandates, and supplier data for a well-rounded pricing model.
Digital Estimating Enhancements
Our estimators apply technology to maximize accuracy and reduce time loss. Key tools include:
- 3D steel model overlays for fireproofing zone allocation
- Automated coverage calculators by UL system and beam type
- Fireproofing-specific crew rates adjusted for vertical reach
- Heat mapping for high-risk inspection areas (e.g., stair shafts)
These insights are especially useful for GC estimators coordinating multiple trades or subcontractors preparing fireproofing-only bids.
Summary
Fireproofing estimation isn’t just about surface areas—it’s about regulatory compliance, thermal protection thresholds, and inspection readiness. Especially in New York City, where bid compliance is non-negotiable, your fireproofing estimate should reflect actual data and local practices.
At True Bid Data, we offer the tools, insights, and NYC-specific intelligence needed to get your fireproofing scope right—on time, every time.
