Masonry jobs are won or lost on labor productivity — block per hour, brick per hour, lineal feet of stone per day. Without real-time tracking by wall type and crew, variance from estimate is discovered at closeout.
Masonry is priced by the unit — block per square foot, brick per unit, lineal foot of stone. Without tracking actual units placed per crew hour against estimated units per crew hour, production variance is invisible. A job that budgeted 12 CMU block per mason-hour and is running at 9 is 25% behind on productivity. At closeout, the loss is already embedded. In week two, it can still be addressed.
Scaffold erection, adjustment, and dismantling is time-consuming and often not separately estimated in masonry bids — it is absorbed into the general labor rate. On a 3-story building, scaffold cost can represent 8–12% of total masonry labor. Without a scaffold cost code, that time is invisible in job costing and the masonry productivity rate appears lower than it actually is.
A masonry contractor doing CMU structural walls, face brick veneer, and stone accent work on the same job has three different productivity rates and three different labor costs per unit. Blending them into one labor code makes all three invisible. The structural CMU might be on budget while the stone accent is 40% over estimated labor — but the blended average looks acceptable until closeout.
SPM builds ControlQore cost codes by masonry type — CMU block (by block size), face brick, stone or architectural CMU — and by phase: scaffold setup, masonry placement, mortar/joint work, and cleanup. Each crew posts time to the correct type and phase combination daily. Weekly actual cost per unit by type compared to estimated cost per unit from the bid.
Foremen log daily: units placed by type (CMU count, brick count, SF of stone), crew hours by type, and scaffold adjustment hours separately. The daily log takes 10 minutes. It produces the data for weekly productivity calculation — actual units per mason-hour by type against the estimated rate. Variance is visible in week two, not at closeout.
Scaffold erection, adjustment, and dismantling time posts to a dedicated scaffold cost code — not to masonry placement. This separates the two activities so masonry productivity rates reflect actual placement time, not placement plus scaffold time blended together. When scaffold cost is visible separately, it can also be compared to what was allowed in the estimate — and the gap becomes a potential change order if conditions required more scaffold than planned.
Some GCs consistently generate more favorable masonry conditions — better phasing, cleaner access, cooperative project management — than others. ControlQore job costing by GC shows which relationships produce better productivity outcomes over time. The data drives capacity allocation decisions and future bidding strategy.
The masonry-specific client outcome is from practice — the broader principle applies directly. When SPM implemented per-unit job costing for a client, previously invisible productivity variance became the data that drove every production decision.
Net profit on $5.2M revenue after job costing revealed which work was losing money and which was profitable — the same dynamic applies directly to masonry productivity variance by wall type.
