WHY PAVING CONTRACTORS LOSE MARGIN ON JOBS THAT LOOK PROFITABLE.

QUICK ANSWER

Paving cost per ton is your production standard — total labor and equipment cost divided by tons placed, tracked by phase type. Parking lot paving runs at one cost per ton. Road paving runs at a different rate. Patching and overlay work has a completely different cost structure — more setup time per ton, smaller batch sizes, more equipment moves. A paving contractor who tracks all labor and equipment in one job code cannot see which phase types are profitable and which are absorbing margin from the ones that work.

CFOS builds tonnage-based cost tracking into every paving engagement — labor and equipment cost per ton by phase type, tracked weekly against the estimated rate so variance is visible before it consumes the remaining scope.

$/Ton
The Right Paving Metric
Total labor and equipment cost per ton of asphalt placed, by phase type — parking lot, roadway, patching, overlay. Not total dollars against a lump budget.
3–5 Phase Types
Minimum Phase Breakdown
Parking lot, road, patching, overlay, and base course each have fundamentally different production rates and cost structures. One code for all paving obscures which work types actually make money.
Patching
Highest Cost Per Ton — Usually Underestimated
Patching and small repair work has the highest cost per ton of any paving phase — more mobilization per ton, smaller loads, more equipment repositioning. Most estimates underprice it because the per-ton rate from large pour jobs is used as the benchmark.
THE BLENDED COST PROBLEM
Using Parking Lot Rates to Estimate Patching Work

A paving contractor who places 2,000 tons of parking lot base and surface in a single pour builds a cost-per-ton history based on that efficient operation. The same contractor then wins a patching contract — 200 discrete patches across a 40-acre industrial site, ranging from 10 to 80 tons each. The estimate uses the parking lot cost-per-ton as the benchmark. The patching job runs 40% over because the setup time, equipment repositioning, small load premiums, and crew idle time between patches were never captured in the parking lot history.

Phase-type cost tracking creates separate cost-per-ton benchmarks for each work type. Patching history informs patching estimates. Parking lot history informs parking lot estimates. Each phase type builds its own accurate cost baseline over time.

THE EQUIPMENT COST PROBLEM
Paver and Roller Idle Time Changes the Per-Ton Rate

Paving equipment cost is typically charged as an all-in daily or shift rate — paver, roller, and support equipment. On large continuous pours, that equipment is running efficiently and the cost per ton is low. On patching work, the paver may run for 20 minutes, sit for 45, run for 15, sit for 60. The daily equipment cost is the same. The tons placed are a fraction of a full-day pour. Cost per ton on patching work with an inefficient equipment utilization day can be three to four times the cost per ton on a continuous parking lot pour.

CFOS tracks tons placed by phase type against equipment hours running — not just equipment hours on site. When cost per ton exceeds the estimated rate by more than 15%, the cause is investigated: equipment utilization, batch size, load delivery timing, crew composition, or changed conditions on site layout.

THE MATERIAL COST PROBLEM
Asphalt Price Volatility Changes the Margin on Fixed-Price Work

Asphalt mix price is tied to liquid asphalt cement, which moves with oil prices. On a fixed-price paving contract signed 6 months before mobilization, a $12 per ton increase in mix price from the time of bid to time of placement is a direct margin hit. Most paving contracts have no escalation clause for material price changes. On a 3,000-ton job, that $12 swing is $36,000 in unrecovered material cost.

CFOS tracks material cost per ton — not just total material cost — against the bid price every delivery. When actual mix price exceeds bid price by more than 5%, CFOS reviews the contract for any escalation provisions and, if none exist, factors the variance into the cost-to-complete and future bid pricing.

01
TRACK TONS PLACED BY PHASE TYPE EVERY POUR
Every pour is coded to a phase type — parking lot, roadway, patching, overlay, base course. Tons placed are recorded from delivery tickets. At week end, cost per ton by phase type is calculated and compared to the estimated rate. Variance above 10% triggers a review.
02
SEPARATE EQUIPMENT HOURS RUNNING FROM HOURS ON SITE
Track the hours each piece of paving equipment is actually running versus total hours on site. When utilization drops below 70%, identify the cause — delivery delays, inter-patch moves, crew wait time — and adjust sequencing or address with the GC if caused by access issues.
03
TRACK MATERIAL COST PER TON FROM DELIVERY TICKETS
Every delivery ticket records tons and total price. Calculate actual mix cost per ton and compare to bid price. When actual mix price exceeds bid by more than 5%, review contract for escalation provisions and adjust cost-to-complete accordingly.
04
BUILD PHASE-TYPE COST BENCHMARKS FROM ACTUAL JOB HISTORY
After each completed job, CFOS produces a cost-per-ton summary by phase type — direct labor, equipment, and material per ton for each work type. These benchmarks replace generic industry tables in future estimates and produce bids that accurately price each phase type based on what it actually costs your operation.

COMMON QUESTIONS

FREQUENTLY ASKED.

Separately, using phase-type specific cost benchmarks. Patching cost per ton is typically two to four times the cost per ton of large continuous parking lot pours — due to more setup time per ton, smaller batch sizes, more equipment repositioning, and higher crew idle time between patches. Using parking lot cost-per-ton rates to estimate patching work underprices the job before a single ton is placed.
Four common causes: equipment utilization below plan due to delivery delays or patching inter-patch moves; higher mix price than bid due to asphalt price volatility; smaller batch sizes than estimated requiring more loads and higher per-ton delivery premium; and more setup and breakdown per ton than estimated on patching work. Each cause has a different response and different implications for the next bid.
