Union labor estimating · Clark County, Nevada · private preview
Every number traces to a source
you can see.
Reef prices loaded union labor for Las Vegas commercial work the way each CBA actually works — OT ladders, night premiums, zone adders, prevailing-wage floors — and keeps the document behind every line one tap away.
The rate sheet you bid from is a liability.
Shadow spreadsheets go stale. Wage sheets turn over mid-determination-year; amendments land in July; the sheet on your shared drive doesn’t know that.
Night work is priced by folklore. Each local prices off-shift differently — straight OT, window rules, percent-of-base — and guessing the wrong structure swings a bid by five figures.
Fringe-on-OT burns you quietly. Whether fringes ride the multiplier is a per-agreement question, and most sheets don’t even ask it.
Proof, not vibes
Tap any line. Get the document.
Every rate line in Reef opens to its source: the agreement title, the effective period, the actual document text, and a link to the archived PDF.
UA Local 525 journeyman base — $60.00 wage + $27.43 fringes = $87.43 package — verified on the MLA wage sheet and corroborated to the penny by the prevailing-wage determination.
Same job, four trades
Flip the shift. Watch the board reorder.
On day shift, Laborers 872 is the cheapest crew on the board at $76.30/hr effective. On third shift their agreement prices night crews at overtime rates — and the same crew becomes the most expensive at $116.03/hr. Reef prices each local’s premium the way its agreement actually reads: straight OT for Laborers 872, a 1.5× window rule for SMART 88, +30% of base for IBEW 357, +8% for UA 525.
Bid day
Walk in with a topsheet, not a browser tab.
One printed page: crew, schedule, loaded straight-time and OT buckets per classification, blended and effective crew rates, weekly burn, and the total — with every assumption named and numbered.
The footer carries the dataset id, its effective window, and a permalink that reopens the exact scenario — text it to your PM and they see your numbers, not a screenshot of them.
Green means verified. Amber means we tell you.
Reef refuses to emit a silently wrong number. Every line is either verified against a source document or flagged as a named assumption — never hidden, never averaged away.
- Amber lines say exactly what’s missing and what resolves it — down to which allocation sheet to ask the union office for.
- Assumptions ride along to the printed topsheet, named and numbered — they never disappear between the screen and the bid.
- Shared links pin the dataset version; if the data has moved since, you get a banner, not a silent re-price.
- Inputs the dataset can’t price honestly return an error — not a plausible-looking guess.

The 2025–26 dataset (effective 2025-10-01 → 2026-09-30) cites 15 sources: the NV prevailing-wage determination and its amendments, MLA wage sheets, union-published rates, and an NJAB arbitration decision — each archived, excerpted, and linked from the lines it backs.
Priced per scenario: OT ladders and weekend rules, shift differentials, travel-zone adders, NRS 338 prevailing-wage floors with certified-payroll treatment, apprentice steps, MCAA-style condition factors, and named exclusions (shop burden, small tools, per-diem).
Questions estimators ask
Where do the rates come from?
From the documents that govern the work: collective bargaining agreements and their wage sheets, the Nevada prevailing-wage determination and its amendments, and union-published rates. Every line links to its source, with the effective period and retrieval date shown.
What happens when a number can’t be verified?
It turns amber. The line stays priced with a named assumption, and the popover states what’s unverified and exactly what resolves it. Amber never hides — it follows the number onto the printed topsheet.
Which trades and jurisdictions?
Today: UA 525, IBEW 357, SMART 88, and LiUNA 872 for Clark County commercial work, on the 2025–26 determination year. More trades and jurisdictions follow the same source-first pipeline.
