The plumbing estimating problem

Multi-system scopes (domestic water, sanitary, storm, gas, specialty) plus fixtures, valves, hangers, and insulation make plumbing bids slow and error-prone. Vendor quotes arrive in different formats and common allowances get missed. TIBR standardizes estimates so your team moves faster with fewer change orders.

Inconsistent vendor formats → hard to normalize and compare
Missed allowances (sleeves, firestopping, insulation, testing) → margin risk
Manual proposal formatting → slow responses in competitive cycles

How works for plumbing contractors

Capture scope fast. Speak or paste notes for domestic water, sanitary, storm, gas, vent, and specialty piping; fixtures and equipment.
AI builds the estimate. Standard sections for systems, risers/branches, fixtures, valves, equipment, hangers, insulation, and testing.
Gap-checking prompts. Sleeves/penetrations, firestopping, trap primers, cleanouts, carriers, seismic, condensate, backflow, permits.
Clarifications, exclusions, alternates. Auto-attach language to de-risk award and support VE decisions.
Export & share. PDF/Word/CSV or a branded proposal link with version history.

How a plumbing bid actually works in

You get a call to bid a 150-unit multifamily rough-in. You open TIBR and start talking — "four-story wood-frame, domestic water risers with PEX distribution, cast iron sanitary and storm, gas to each unit, roof drains and overflow, 150 fixture units per floor." Within seconds the estimate is broken into sections: domestic water, sanitary, storm, vent, gas, and site utilities.

Then the prompts start. Did you include trap primers on the floor drains? Cleanouts at every change of direction per code? Seismic bracing on the risers? Firestopping at every floor penetration? Test allowances for each system? You answer yes or no, and the line items appear — or don't. No guessing, no midnight "did I forget something" panic.

Because you bid a similar 120-unit project two months ago, TIBR pulls that job's structure and pre-fills quantities you can adjust floor by floor. You review, tweak the fixture count for the penthouses, add an alternate for PVC storm instead of cast iron, and export a branded PDF with every system itemized, clarifications attached, and your company logo on the cover. Total time: under two hours for a bid that used to take three days.

TIBR vs. quoting plumbing jobs by hand

Most plumbing contractors still quote from a combination of Excel, old proposals, scribbled field notes, and memory. You re-type the same fixture schedule you typed last month. You forget the firestopping allowance until the GC asks for it. You spend a full day formatting the proposal to look professional, then realize at 11pm that you left out the backflow assemblies on the domestic water riser. The bid goes out late, the number is wrong, or both — and you don't find out until the change order hits.

In TIBR, that same job starts with a reusable template for the building type. Your cost libraries already have labor rates, material pricing, and assembly costs by system — domestic water, DWV, gas, storm — so you're pricing, not building a spreadsheet from scratch. Prompted checklists catch the items you'd normally miss. The proposal exports with system-by-system line items, clarifications, and exclusions already formatted. Same job, same-day turnaround, and you actually sleep that night.

Project types plumbers quote with

New construction rough-in (multifamily & commercial). The biggest scope complexity — multiple risers, hundreds of fixtures, and every system from domestic water to gas. TIBR organizes the estimate by system and floor so nothing gets buried in a single lump-sum line.

Tenant improvement plumbing. TI jobs mean working around existing mains and figuring out what stays, what gets capped, and what's new. TIBR separates demo/cap-off scope from new work and prompts for the tie-in details that usually surface as RFIs after award.

Retrofit and renovation. Older buildings mean unknown conditions — galvanized to copper transitions, undersized vents, lead joints. TIBR flags allowances for exploratory demo, abatement, and code-upgrade items that protect your margin when the walls open up.

Service and repair quoting. Smaller scope, faster turnaround. TIBR handles T&M and flat-rate quotes with saved rate cards so you can price a water heater swap or re-pipe from your truck without opening a laptop.

Medical gas and specialty systems. Oxygen, vacuum, nitrogen, and waste anesthetic gas each have unique material specs, testing requirements, and certification needs. TIBR keeps these scopes separate with their own checklists so they don't get lumped into general plumbing and underpriced.

Integrations & outputs

Exported proposals are itemized by system — domestic water, sanitary, storm, gas — with your company branding, clarifications, exclusions, and alternates attached. GCs and owners get a document they can actually compare against other bids, not a single lump-sum number with no backup.

Cost libraries store your material prices, labor rates, and assembly costs by system and fixture type. Update copper pricing once and it flows into every future bid — no more hunting through old spreadsheets for last quarter's rates. Export to PDF, Word, or CSV depending on what the GC needs.

Accounting integrations with QuickBooks Online and Xero are on the roadmap. See pricing for current plan details.

Results plumbing teams see

Plumbing bids that took two to three days by hand now go out same-day. The difference isn't just speed — it's what you stop losing. Prompted checklists mean fewer missed items, which means fewer change orders eating your margin after award. Clarifications and exclusions are built into every proposal, so the RFI count drops because the GC already has the answers.

The proposals themselves look different too. Instead of a spreadsheet attachment or a one-page lump sum, GCs get a system-by-system breakdown with clear assumptions — the kind of document that makes your bid easier to approve. Contractors using TIBR report higher win rates not because the price is lower, but because the proposal is the one the project manager actually wants to read.

FAQs

How do I estimate a plumbing job?

Start by breaking the scope into systems — domestic water, sanitary, storm, gas, and vent — then count fixtures, fittings, valves, and hangers for each run. Include allowances for sleeves, firestopping, insulation, and testing or you'll eat those costs later. TIBR structures this breakdown automatically so nothing falls through the cracks.

What software do plumbers use for quoting?

Most plumbing contractors still quote from spreadsheets or memory, which is why bids are inconsistent and slow. Dedicated estimating tools like TIBR let you build itemized proposals by system — DWV, domestic water, gas, specialty piping — with prompted checklists for the items that typically get missed.

How accurate is plumbing estimating software?

Accuracy depends on the scope detail you capture, not the tool alone. The advantage of software over a blank spreadsheet is forced structure — it won't let you skip fixtures, rough-in counts, or testing allowances. TIBR adds AI prompts that flag commonly omitted items like trap primers, cleanouts, and backflow assemblies before you send the bid.

How long does it take to quote a plumbing job?

A multi-system commercial plumbing bid typically takes one to three days by hand, depending on how many fixtures and systems are involved. With templates and reusable cost libraries, contractors using TIBR cut that to hours — the structure is already built, so you're pricing, not formatting.

Does TIBR handle both commercial and residential plumbing estimates?

Yes. Commercial bids can be organized by system — domestic water, sanitary, storm, gas — and broken down by floor, area, or phase. Residential estimates group by room or zone, which works well for new-build rough-ins, renovation re-pipes, and fixture-swap quotes. The same cost libraries and prompted checklists apply to both, so you get the same consistency whether you're bidding a 200-unit multifamily or a single-family bathroom remodel.

Can I itemize fixtures and specialty equipment?

Every fixture — water closets, lavatories, floor drains, interceptors, water heaters, backflow assemblies — can be listed as its own line item with material cost, labor hours, and installation notes. You can save fixture assemblies (for example, a standard carrier-plus-flush-valve package) to your library and drop them into future bids without re-entering specs. Specialty equipment like booster pumps, mixing valves, and recirculation systems get the same treatment.

Will TIBR prompt for commonly missed plumbing items?

The prompts cover the items that most often show up as change orders after award: sleeves and penetrations, firestopping at rated assemblies, trap primers on floor drains, cleanouts at changes of direction, insulation on domestic water risers, seismic bracing, test and flush allowances, and permit fees. You can dismiss any prompt that doesn't apply, but you won't accidentally skip one because you were rushing to get the bid out.

Can I save templates for repeat plumbing jobs?

Yes. If you regularly bid the same building types — say, four-story wood-frame multifamily or ground-up medical office — you can save the full estimate structure as a template. That includes systems, fixture counts, allowances, clarifications, and exclusions. On the next similar job, you start from the template and adjust quantities instead of rebuilding the scope from scratch. Your cost libraries carry over too, so material and labor rates stay current across bids.

What export options are available?

Proposals export to PDF, Word, or CSV. The PDF output is branded with your company logo and organized by system — each section shows line items, quantities, unit costs, and subtotals. Clarifications, exclusions, and alternates are included as appendices. You can also share a web-based proposal link with version history, so the GC always sees the latest revision. Accounting integrations with QuickBooks Online and Xero are on the roadmap.
