WATERPROOFING · ENVELOPE AND STRUCTURE · FIXED BY STEP 01

Four Clocks Decide When You Can Start, Cover, Or Bill

Crew is on site, membrane is on the ground, and the envelope consultant flies in Thursday. Four approvals come between your people and a billable square foot, and you hold none.

WHY IT'S A WATERPROOFING PROBLEM

Plenty of trades wait on inspection. Waterproofing waits on inspection before it can start, again before it can cover its own work, and again before the deck above it can proceed, with a third-party consultant who bills by the trip and flies in from somewhere else. If you miss the observation window, completed and buried work gets dug back up, and almost no other scope has that penalty.

WHAT IT COSTS

The size of it

Crews wait at full burdened cost with no line item to bill against, and two standby days a month on a four-man crew is roughly $6,000 to $9,000 of unrecovered labor. Your books read it as a productivity problem when the cause was an owner-caused delay.

Substrate acceptance comes first: the concrete has to be cured and dry, and a curing compound or form release picked by the concrete sub can disqualify the surface outright. Next comes a field mock-up, which has to be built and accepted by the architect or a registered envelope consultant before production work releases. Nothing gets backfilled or overburdened until an IIBEC-credentialed observer or ABAA field auditor signs off on cover. After that, a 24 to 48 hour flood test per ASTM D5957 runs on the decks, scheduled by the GC and witnessed by the consultant. That's four calendars, not one of them yours, and your crew is on the job for all of it.

WHAT TO DO

Three moves, in order

STEP 01
Build standby and mock-up as their own cost codes at job setup so idle days get captured with a date and a cause instead of smearing into install labor.
STEP 02
Break the four gates out as separate lines on the schedule of values: mock-up approval, substrate acceptance, pre-cover observation, and flood test. Bill the mock-up the week it's accepted.
STEP 03
Get three things in writing at the pre-install meeting: who the consultant is, the required observation notice period, and the flood test window. When a date moves, send notice that day with your crew count attached.
QUESTIONS

What waterproofing owners ask

Waterproofing crew standby waiting on envelope consultant?

Crew is on site, membrane is on the ground, and the envelope consultant flies in Thursday. Four approvals come between your people and a billable square foot, and you hold none.

What does it cost?

Crews wait at full burdened cost with no line item to bill against, and two standby days a month on a four-man crew is roughly $6,000 to $9,000 of unrecovered labor. Your books read it as a productivity problem when the cause was an owner-caused delay.

What do I do first?

Build standby and mock-up as their own cost codes at job setup so idle days get captured with a date and a cause instead of smearing into install labor.

What are waterproofing contractors supposed to be making?

Waterproofing runs 26% gross margin, 17% overhead and 9% net profit before taxes at $1M–$5M. The all-trade average is 7%, so this trade is 2 points above it. The CFOS target is 12.5%.

Which part of the system fixes it?

The step is number 01, job cost structure. Seven cost categories and three levels of granularity, built so the estimate and the ledger use the same words. It comes from chapter 1 of CONTROL: The Construction Financial Operating System.

OR HAVE IT HANDLED

Everything on this page is something you can install yourself, andCONTROL is the order to do it in. If you would rather buy the finished result, SPM The Construction CFO does this work for waterproofing contractors as a service. It is a separate firm, Sulphur Prairie Management, LLC, run by the same author.
