Example data table

Scenario Basis Quantity Truck capacity Distance (one-way) Trips Total hours
Soil export Volume 300 cy, swell 1.15 14 cy, load 0.90 12 mi 28 ~22.3
Concrete rubble Weight 500 ton 18 ton, load 0.90 8 mi 31 ~18.6

These examples are illustrative. Update inputs to match your trucks, route, and disposal rules.

Formula used

1) Volume-based trips
Convert in-place volume to haul volume, then divide by effective capacity.
Loose Volume = In-place Volume × Swell Factor × Overage Factor
Adjusted Volume = Loose Volume ÷ Shrink Factor
Effective Capacity = Truck Capacity × Load Factor
Trips = ceil(Adjusted Volume ÷ Effective Capacity)
2) Weight-based trips
Apply allowance, then divide by effective payload.
Effective Payload = Payload Limit × Load Factor
Trips = ceil((Total Weight × Overage Factor) ÷ Effective Payload)
3) Cycle time and cost
Use distance, speed, and fixed times to estimate total hours and costs.
Drive Time (round) = 2 × (One-way Distance ÷ Average Speed)
Fixed Time = (Load + Dump + Queue + Turnaround) ÷ 60
Cycle Time = Drive Time (round) + Fixed Time
Total Hours = Trips × Cycle Time

How to use this calculator

  1. Choose volume-based for excavation, or weight-based for dense materials.
  2. Enter quantity, truck capacity or payload, and a realistic load factor.
  3. Add an overage factor for spillage, rework, or measurement uncertainty.
  4. Enter route distance and speed, then add loading and disposal delays.
  5. Review trips, total hours, and the cost breakdown above the form.
  6. Download CSV for estimating sheets, and PDF for reporting.

Scope of haul-off planning

Haul-off trips influence schedule, safety, and cost for earthwork and demolition. This calculator converts material quantity and truck capacity into trips, then combines distance and delays into total hours. Use it early to test dump sites, haul routes, and truck sizes. Update forecasts when weather, access, or disposal queues change. Better forecasting reduces idle loaders and prevents surprises.

Choosing volume versus weight inputs

Volume inputs fit excavated soils, topsoil, and mixed debris where bodies fill before legal payload. Convert in-place bank volume to loose hauled volume using swell, then apply an overage factor for losses and rehandle. Weight inputs fit concrete, rock, and scrap where payload limits control each load. If both volume and weight matter, run both and plan using the larger trip count.

Improving trip accuracy with efficiency factors

Rated capacities assume perfect loading. The load factor represents typical fill, accounting for operator technique, moisture, oversized pieces, and safety margins. A shrink or compaction factor can adjust volume when material is conditioned for transport. The overage factor adds allowance for cleanup, rejected loads, and uncertainty. Together, these factors shift the estimate from theoretical to field-credible.

Cycle time drivers and productivity

Cycle time combines round-trip driving and fixed delays such as loading, queueing, dumping, and turnaround. Driving time should use realistic average speed, not posted limits, because grades, intersections, and congestion slow trucks. Queue time can dominate busy periods. Total hours equals trips times cycle time, which supports staffing decisions and daily production targets. Estimate trucks needed by dividing required trips by cycles per truck within available shift hours, then round up.

Using cost outputs for bid control

Costs merge time-based trucking, distance-based fuel, tipping fees, and a contingency percentage. Compare scenarios such as a closer facility with higher tipping versus a farther facility with lower rates. The breakdown helps isolate drivers: long hauls increase hours and fuel, while high tipping dominates short hauls. Export CSV and PDF to document assumptions and support change management.

FAQs

1) What if my truck body capacity is higher than legal payload?

Run the weight-based method using the legal payload limit. Use the volume method as a check, then plan for whichever produces more trips.

2) How should I choose a swell factor?

Use local geotechnical data, prior jobs, or measured truck counts from similar material. When uncertain, test a low and high swell to bracket risk.

3) Does the load factor include underloading for road safety?

Yes. Set it below 1.00 to reflect consistent underfills, tarp requirements, uneven fragments, or operator constraints that prevent full loads.

4) How do I account for dump site waiting lines?

Increase queue time to match peak conditions. If queues vary by hour, run multiple scenarios and schedule hauling outside the worst periods when possible.

5) Can I estimate truck counts for a daily target?

Yes. Use cycle time and your shift hours to estimate cycles per truck, then divide required trips by that value and round up.

6) Why do my costs look high compared to a lump-sum quote?

Quotes often bundle fuel, standby, and disposal assumptions. Align your hours, tipping, and distance with the hauler’s scope, then adjust contingency to match your risk tolerance.
