IFC Cost Estimation & Budgeting 3

Question 1

A firestop estimator is comparing two sealant products: Product A costs $12/tube and covers 4 linear feet per tube; Product B costs $9/tube and covers 3 linear feet per tube. Which product has the lower cost per linear foot?

Accepted Answer

Both products cost the same per linear foot

Answer

Product A costs $3.00/LF ($12÷4) and Product B also costs $3.00/LF ($9÷3), making them equivalent on a per-linear-foot basis.

Question 2

In IFC firestop project budgeting, what is the purpose of including a 'deficiency correction' line item?

Accepted Answer

To budget for rework when penetrations fail inspection or are installed incorrectly

Answer

A deficiency correction line item covers the cost of rework when penetrations are found non-compliant during inspection, which is a normal risk on firestop projects.

Question 3

Which estimating database is most commonly referenced by US firestop contractors when establishing benchmark unit costs?

Accepted Answer

RSMeans Construction Cost Data

Answer

RSMeans Construction Cost Data is the industry-standard reference for benchmark labor and material unit costs used by US contractors across all trades including firestop.

Question 4

A firestop subcontractor is bidding a project where 30% of penetrations are in occupied, operational areas requiring night-shift work. How should this impact the labor estimate?

Accepted Answer

Apply a shift premium multiplier to the affected labor hours

Answer

Night-shift or premium-time work in occupied buildings requires applying a shift differential or premium multiplier to the labor hours worked in those conditions.

Question 5

What is the primary reason firestop estimates on renovation projects often exceed original budgets?

Accepted Answer

Unforeseen penetrations and non-compliant existing conditions discovered during demolition

Answer

Renovation projects frequently reveal undocumented penetrations and non-compliant existing firestop conditions that were not visible during the estimating phase.
