Fire Protection & Plumbing Estimating Services

Plumbing mistakes rarely show up on bid day. They show up after rough-in, buried behind walls you’ve already closed up a missed fixture count, an undersized main, a sprinkler head layout that doesn’t quite match the fire protection design. By the time anyone catches it, you’re looking at demo, re-installation, and a schedule delay that makes you the reason the GC’s project is behind.

That risk gets worse when domestic water, fire mains, and mechanical room coordination are estimated as two disconnected trades instead of one coordinated scope. Our CSI Division 21 and 22 estimating services price fire protection and plumbing together, specifically to close the scope gaps that show up at the mechanical room wall  where fire mains, domestic water services, and equipment connections all have to line up correctly the first time. The result is a bid-ready estimate you can submit directly to the GC, built for contractors bidding commercial, residential, industrial, and public projects across the United States.

What We Take Off — Division 21 & 22, Coordinated Together

• Fire sprinkler systems (wet, dry, pre-action, deluge)
• Standpipes, hose valves, and fire department connections (FDCs)
• Fire pumps, tanks, controllers, and accessories
• Underground fire mains and domestic water services
• Cold and hot domestic water distribution systems
• Sanitary, waste, vent (DWV), and storm drainage piping
• Gas piping and plumbing equipment connections (where applicable)
• Fixtures, trims, valves, fittings, hangers, sleeves, and insulation
• Testing, flushing, commissioning, and close-out scope

Nothing here is estimated as a rough per-fixture average. Piping is quantified by size and material, sprinkler heads are counted against the actual fire protection layout, and equipment is priced to spec  because a fire suppression system in particular is life-safety work, and a missed device or an incomplete zone count can hold up an entire building’s certificate of occupancy.

Why Plumbing Contractors Value Our Estimates

• Confirmed quantities, measured strictly per plans and specifications not a rule-of-thumb sizing
• Itemized material lists ready for supplier pricing and ordering, so procurement starts on solid numbers
• Fewer RFIs, fewer change orders, better execution because the scope was right the first time, not discovered wrong at rough-in
• A bid proposal ready to submit to GCs, with no reformatting needed on your end

When your bid holds up from rough-in through final inspection, that’s what turns a single awarded job into a GC calling you directly for the next on instead of shopping your price against three other subs every time.
