TL;DR: Concrete flatwork contractors track cost per SF by allocating crew hours, equipment hours, and pump cost to cost codes by pour type in ControlQore. Parking lot slab, interior slab-on-grade, elevated deck, and sidewalk each get their own cost code. Actual cost per SF by pour type is calculated weekly against estimated rate. When elevated deck is running at $8.50 per SF against a $6.80 per SF estimate in week two there is still time to find the cause and act.
Concrete Flatwork
SF Cost Tracking for
Concrete Flatwork Contractors.
Concrete flatwork margin lives or dies in the cost per SF by pour type. If you cannot see that number weekly by pour type you cannot manage it. Here is how SPM builds the tracking system.

The System
Cost Codes by Pour Type in ControlQore
Four pour types, four cost codes. Every hour of crew time and equipment time posts to the pour type it belongs to. Pump hours and pump rental post to the specific pour as a direct cost. At the end of each week: actual cost per SF by pour type against estimated rate. Variance visible before it compounds into a loss.
Parking Lot and Exterior Flatwork
Target: $3.50-$5.00 per SF total. Simple geometry, standard reinforcement, ground-mounted pump or truck chute. Cost code tracks crew hours, rebar placement, concrete pour, and finishing separately. When any sub-phase runs over estimate the cost code detail shows which one.
Interior Slab-on-Grade
Target: $4.00-$5.50 per SF. More formwork complexity, tighter tolerances, vapor barrier. Tracked separately from exterior flatwork because production rates and crew time per SF differ. Blending the two hides variance in both.
Elevated Deck
Target: $6.50-$9.00 per SF. Shoring, formwork, pump mobilization, post-tensioning or rebar at structural density. Pump cost tracked as a direct cost code to this pour type not to overhead. Elevated deck cost per SF needs to be accurate to price the next bid correctly.
Sidewalk and Miscellaneous Flatwork
Typically $5.00-$7.00 per SF due to small pour size, multiple mobilizations, and hand finishing. Tracked separately because small pour production rates are different from large pour rates. Blending with parking lot flatwork understates the true cost of miscellaneous work.
FAQ
Frequently Asked Questions
How should concrete flatwork contractors track cost per SF?
Cost codes by pour type in ControlQore - parking lot slab, interior slab-on-grade, elevated deck, sidewalk. Foremen log actual crew hours and equipment hours by pour type daily. Actual cost per SF by pour type calculated weekly against the estimated rate from the bid. When interior slab is running at $2.85 per SF against a $2.20 per SF estimate in week two there is still time to identify the cause and adjust.
What is a good cost per SF for concrete flatwork?
Parking lot and exterior flatwork: $3.50-$5.00 per SF total cost (labor plus materials plus equipment). Interior slab-on-grade: $4.00-$5.50 per SF. Elevated deck: $6.50-$9.00 per SF depending on forming system. These ranges vary significantly by market, pour complexity, and reinforcement requirements. The number that matters is your actual cost per SF against your estimated cost per SF on the same pour type.
Why does concrete flatwork have cash flow problems?
Three consistent causes: pump costs absorbed as overhead rather than allocated to pours, SOV that back-loads billing to project completion rather than pour completion milestones, and AR sitting uncollected at 45+ days. Pump cost allocation and SOV front-loading are billing structure fixes. AR collection is a weekly process fix. SPM addresses all three in the first 60 days.
How does pump cost affect concrete flatwork job costing?
Pump rental and operator represent 8-15% of total pour cost on elevated slabs. When pump cost is booked to equipment overhead rather than allocated to specific pours the cost per SF on elevated pours appears artificially low and standard pours appear artificially high. The variance is invisible until closeout. Pump cost tracked as a direct cost code by pour produces accurate per-SF cost by pour type.
