FAQ
Fire Protection Estimating, answered.
Talk to an estimator
Not a salesperson. Same-day answers on working days.
+1 518 974 7222[email protected]Do you estimate before hydraulic calculations exist?
Yes. Head counts and pipe are estimated from the hazard classification and ceiling plans, with the design calculations carried as an item.
Are fire pumps included?
Yes. Fire pumps, controllers, standpipes and the fire department connection are measured where the drawings show them.
Can you use our cost book and labor rates?
Yes, and we prefer it. Your historical costs reflect your crews and your suppliers better than any published average. Send the template and we work inside it.
How does pricing work?
Pricing is per project and quoted before any work starts — no retainer, no minimum volume and no subscription.
Do you sign NDAs?
Yes. Drawings, specifications and pricing are treated as confidential by default, and we sign your NDA on request before any documents change hands.
