WHY MASONRY CONTRACTORS LOSE MARGIN ON LABOR.

QUICK ANSWER

Masonry labor productivity is units per hour — block laid, brick courses set, stone veneer installed. Your estimate embedded a specific production rate for each phase. When the job runs at a lower rate, every hour over budget comes directly out of gross margin. Most masonry contractors track labor in dollars but not in units, which means the variance is invisible until closeout.

CFOS tracks both — dollars and units by phase — so a crew running at 85% of estimated block-lay rate is visible in week 3, not at final billing.

Units/Hour
The Right Masonry Metric
Not dollars per day. Block laid, brick set, stone installed per labor hour — mapped against the estimated rate at bid time.
2–4 Phases
Minimum Phase Structure
Block vs brick vs stone, rough vs decorative, interior vs exterior. Lumping all masonry labor kills the visibility that drives correction.
Week 3–4
Latest to Catch It
A production rate variance caught at 25% completion has 75% of the job left to recover. Caught at 80%, there is almost nothing left to do.
THE ESTIMATE PROBLEM
Your Bid Assumed a Production Rate You Are Not Tracking

When a masonry contractor prices a block wall, the labor estimate is built on a production rate — courses per hour, block per crew-day, square feet per shift. That rate becomes the standard. Everything that happens on the job is measured against it.

If the estimate assumed 180 block per crew-day and the job is running at 140, the crew is 22% below rate. On $280,000 in remaining labor budget, that variance is $61,600 in unplanned cost — identifiable in week 3 if someone is tracking units. Not identifiable at all if labor is tracked only in dollars.

THE PHASE PROBLEM
Lumping Masonry Labor Hides Where the Bleeding Is

A masonry job typically has multiple distinct work types: CMU block, face brick, stone veneer, mortar work, grout fill, anchor installation. Each has a different production rate, crew composition, and material consumption pattern. Lumping them into one labor code means a $35,000 overrun on stone veneer is buried inside a $180,000 masonry labor line that looks close to budget overall.

Phase-level tracking is where the variance lives. CFOS builds cost codes that match the estimate structure — same phases, same categories — so actual vs estimated is an apples-to-apples comparison by phase, by week.

THE CREW COMPOSITION PROBLEM
Who Is on the Crew Changes the Rate

A masonry estimate built on a journeyman/apprentice ratio of 2:1 runs differently if the crew is 3:1 or 1:1. Fully burdened labor rates diverge significantly between journeymen and apprentices — and production rates diverge too. A crew heavy on apprentices lays fewer units per hour and costs more per unit than the estimate assumed.

CFOS tracks both hours and fully burdened dollars by phase. When a phase runs on budget in hours but over budget in dollars, the cause is crew composition — not a production rate problem. That distinction determines the correct response.

01
BUILD PHASE COST CODES THAT MATCH THE ESTIMATE
Every phase in the estimate needs a corresponding job cost code. CMU block, face brick, stone veneer, grout, anchor — each gets its own code. When the PM logs time, it goes to the right phase. Actual vs estimated is visible by phase by week.
02
TRACK UNITS ALONGSIDE HOURS
Every timesheet captures both hours worked and units completed — block laid, brick courses set, square feet of stone. The ratio is compared to the estimated production rate weekly. Divergence triggers a PM conversation that week, not a post-mortem at closeout.
03
REVIEW AT 25% AND 50% COMPLETION
The 25% review is where production rate variance is first meaningful and still fully recoverable. The 50% review is the last point where crew redeployment or change order capture can materially change the outcome. Both reviews require the owner, PM, and CFO in the same room.
04
LINK PRODUCTION VARIANCE TO CHANGE ORDER REVIEW
When production rate variance is caused by conditions different from those estimated — substrate irregularities, design changes, weather delays affecting masonry cure — that is a changed condition. CFOS links the weekly production review to an open change order log so variance that cannot be explained by crew or sequencing gets evaluated for change order eligibility immediately.

COMMON QUESTIONS

FREQUENTLY ASKED.

Production rates should come from your own job history — not industry tables. Historical actuals on similar work types, crew compositions, and site conditions are more accurate than generic benchmarks. RS Means and similar sources are useful for initial validation. A masonry contractor with 3+ years of phase-level labor tracking has a significant estimating advantage.
By phase and by units alongside dollars. Every timesheet should capture hours worked, phase code, and units completed — block laid, brick set, stone installed. The ratio produces an actual production rate that is compared to the estimated rate weekly. Dollar tracking alone tells you what was spent but not whether the crew is performing to the estimate.
