WHY MASONRY
CONTRACTORS
RUN OUT OF CASH.

QUICK ANSWER

Masonry contractors run out of cash because labor productivity swings heavily by crew and by wall type, scaffold and equipment costs get buried in overhead instead of billed to the job that used them, and weather delays silently eat schedule float without ever showing up as a tracked cost. A masonry contractor can bid a job accurately and still lose the margin entirely to variance nobody was watching.

Masonry is one of the most labor-variable trades in construction. Two crews on the same wall type can produce wildly different results, and if that variance isn't tracked in real time, it shows up as a loss months after the wall is already built.

BY JOSH LUEBKER  ·  UPDATED JULY 2026
THE THREE MECHANISMS
01

Labor Productivity Swings by Crew and Wall Type

Masonry productivity depends on wall type, block size, crew experience, and access, and it can vary widely between two crews on the same estimate. Without job costing that tracks units laid per labor hour, a slower crew's cost overrun stays invisible until the job closes and the margin is already gone.

02

Scaffold and Equipment Costs Get Buried in Overhead

Scaffold rental, hoists, and mixing equipment are often billed to a general overhead account instead of the specific job that used them. That inflates overhead, understates true job cost, and makes every future bid based on that history too low.

03

Weather Delays Erase Schedule Float Without a Cost Record

Masonry work stops in freezing temperatures and heavy rain, and every stoppage eats into the float built into a schedule. Without tracking weather days against the schedule and billing for the impact where the contract allows, the cost of that lost time is never recovered and never even measured.

WHERE TRADE OWNERS GET MISLED

Assuming Every Crew Performs Like the Estimate

An estimate is built on an assumed productivity rate. Real crews vary above and below that rate constantly, and without tracking, you have no way to know which crew is costing you margin until the job is finished.

Treating Scaffold Rental as a Fixed Overhead Cost

Scaffold and equipment used on a specific job are a job cost, not overhead, even when the rental agreement is company-wide. Miscategorizing it hides the true cost of the job that used it and inflates the overhead rate that gets applied to every other bid.

Absorbing Weather Days Without Documentation

A weather day that isn't logged against the schedule is a day of lost productivity that never gets factored into future bids or claims. Document it every time, even when you don't plan to bill for it immediately.

Bidding the Next Job Off the Same Undertracked History

If job cost history is inaccurate because of buried equipment costs and untracked productivity variance, every future bid built on that history inherits the same error.

HOW CONTROL FIXES IT
  • Chapter 1: Track units laid per labor hour by crew so productivity variance is visible in real time
  • Chapter 2: Assign scaffold, hoist, and equipment costs to the specific job that used them instead of general overhead
  • Chapter 3: Calculate real overhead separately so equipment miscategorization stops distorting the rate
  • Chapter 7: Run cost to complete monthly so a slow crew or a weather delay is caught while the job is still open
  • Chapter 4: Align the estimate's assumed productivity rate to the job cost codes tracking actual performance

CONTROL gives masonry contractors the per-crew productivity tracking and equipment cost assignment that keep labor variance from silently erasing the bid. Available October 1, 2026.

FREQUENTLY ASKED QUESTIONS

Crew productivity varies by experience, access, and conditions, and that variance directly drives labor cost per unit laid. Without tracking units laid per labor hour by crew, there's no way to catch an underperforming crew until the job closes.

Scaffold and equipment used on a specific job should be assigned as a job cost to that job, not lumped into general overhead. Miscategorizing it understates the true cost of the job and distorts the overhead rate applied to every future bid.

Log every weather day against the schedule as it happens, even if you don't plan to bill for it right away. That record protects your position if a delay claim becomes necessary and gives you real data on how much float weather costs.

Untracked labor productivity variance is usually the largest one, since it's invisible until the job closes and often gets blamed on the crew rather than the lack of real-time tracking that would have caught it weeks earlier.

Yes. A construction specific fractional CFO installs the job costing structure that tracks labor cost per unit by crew in real time, along with correct equipment cost assignment. Sulphur Prairie Management builds this as part of the CONTROL system.
