Productivity Rate Calculator

How It Works

1. Pick the Mode (Hauling or Fencing)

   The two mode buttons at the top switch between the truck hauling cycle-time calculator and the fencing crew-day rate calculator. Each mode has its own input panels and outputs, but both run on the same shared engine that converts inputs to quantities, then to production rate, then to resource hours, then to duration and cost. Switching modes preserves the inputs for the other mode, so you can flip back and forth on a multi-trade estimate.

2. Hauling: Pick the Material

   The material dropdown selects from eleven Cat PHB material classes (topsoil, common earth dry and wet, clay dry and wet, sand dry and wet, gravel, crushed stone, rock blasted well-fragmented and poorly-fragmented). The material drives the swell factor (bank to loose volume increase), the loose density (lb per loose cubic yard, which determines whether the truck binds on weight or on volume), and the default bucket fill factor for the loader. Selecting common earth dry sets a 25 percent swell, 2240 lb per LCY, and 0.95 bucket fill factor.

3. Hauling: Enter the Project Quantity

   Enter the total quantity to move, and pick whether the number is bank (in-place) or loose (after excavation). Bank is what a survey or plan typically reports. Loose is what the truck hauls. The tool converts between the two using the material swell factor so the duration solve is consistent regardless of which basis the user enters.

4. Hauling: Pick the Loader and Truck

   Select the loader type (small wheel loader 1-3 yd, medium 3-5 yd, large 5-8 yd, track loader, hydraulic excavator). The default bucket capacity, cycle time, and hourly cost are pulled from the Cat PHB ranges, but every value is editable. Enter the truck heaped volume capacity (LCY rating) and legal payload (lb DOT cap). The tool picks the binding limit automatically. For light material the truck binds on volume; for heavy material like wet clay or blasted rock the truck binds on weight and hauls light by volume. Enter the truck count and the per-truck hourly cost (ATRI 2024 ranges $75-115/hr typical, owner-operator or fleet).

5. Hauling: Enter the Haul Cycle

   Enter the one-way haul distance, the loaded speed (typically 25-35 mph on a good haul road), the empty speed (typically 30-40 mph), the dump time (Cat PHB 30-60 sec for highway dump trucks, up to 90 sec for off-highway), and the spot and wait time at the loader (queue plus maneuver, 20-45 sec typical). Pick the efficiency preset (50, 45, 40, 35 minutes per hour) and the work hours per day.

6. Hauling: Read the Verdict

   The verdict panel shows the system production in bank cubic yards per hour and loose cubic yards per hour, the loads per day for the fleet, the cost per BCY and per ton, and the days to complete the project quantity. The match factor gauge shows where the system sits on the 0-2 scale (1.0 is balanced, below is undertrucked, above is overtrucked). The bottleneck text explains the call in plain language. The truck-sizing table shows the current plan, the floor-balance count (one truck below the theoretical balance), the ceil-balance count (one truck above), and the exact fractional balance number. Floor and ceil are not plus or minus one from the current truck count; they bracket the theoretical balance.

7. Hauling: Read the Truck Cycle Breakdown

   The horizontal stacked bar shows each cycle component (load, haul, dump, return, spot and wait) as a colored segment proportional to its share of the total truck cycle time. If the haul segment dominates, the system is haul-limited and the production gain from adding loader capacity is small. If the load segment dominates, the loader is the constraint and adding trucks will not help. The bar is the diagnostic that tells you where to spend the next dollar.

8. Fencing: Pick the Fence Type and Geometry

   Select the fence type (chain link residential 4-6 ft, chain link commercial 6-8 ft, wood privacy 6 ft, wood split rail, welded or field wire 4-5 ft, barbed wire 4-strand, vinyl privacy 6 ft, ornamental steel 4-6 ft, temporary panel rental). The base production rate (LF/crew-day at baseline conditions) loads with the type along with the default post method, post spacing on center, and height. Enter the total length, the actual height, and the post spacing. Specify corner / end / pull posts explicitly or leave 0 for an auto-estimate. Enter walk gates and drive gates. Drive gates take 6 crew-hours each (per RSMeans) and dominate the schedule when present.

9. Fencing: Pick the Site and Method

   Soil class is the single biggest production driver after fence type. Loam is baseline (1.0). Sandy is 1.05, hard clay 0.85, rocky 0.55, frost 0.45, permafrost 0.30. The permafrost factor is calibrated from Alaska DOT&PF construction productivity data, where steam thawing and drilling roughly triple the time per post. Terrain (flat 1.0, rolling 0.85, steep 0.65). Post method (driven 1.25 vs the concrete baseline, rock-drilled 0.50). The custom-rate panel below lets you override the base rate when your tracked production differs from the national-data default.

10. Fencing: Read the Verdict and Line Items

    The verdict panel shows the effective rate in LF/crew-day after all modifiers, the labor days (crew-days), the calendar days (labor plus any concrete cure lag), the cost per linear foot, and the total project cost. The line-item table breaks the headline crew hours into layout and string, post holes, post setting, rail and fabric, gates, and tension and trim, so the estimate is defensible against a takeoff. Concrete cure is shown as calendar time only, not labor time, and only adds calendar lag on short jobs (less than three labor-days) where the cure forces a forced gap rather than overlapping later work.

11. Fencing: Save Your Company Rates

    The base production rates ship with national-data defaults (RSMeans 2024 cross-checked with American Fence Association install guides). Once you have tracked your crews' actual production on a job, enter the tuned LF/crew-day in the Custom Rate Override field and click Save as Company Default. Next time you open the tool for the same fence type, the saved rate loads. This is the difference between an estimate tuned to national averages and an estimate tuned to your specific crew. Saved rates persist in local storage on the device and do not sync across devices.

12. Export the Report

    PDF export produces a branded, page-break-safe report with the verdict, the cycle breakdown or rate-build, the line-item breakdown, the inputs block, the methodology and sources block, and any active flags. Suitable for handing to a PM, a foreman, or stapling to a bid. CSV export packages every input and every output for spreadsheet import. Share-URL encoding lets a teammate open the exact same calculation without retyping.

Features & Capabilities

Match Factor with Bottleneck Verdict

Match factor MF = (n_trucks × load_time) / truck_cycle_time. MF = 1.0 is balanced. MF < 1.0 means the loader sits idle waiting for trucks (truck-bound). MF > 1.0 means trucks queue at the loader (loader-bound). The tool reports the value, the verdict, and the truck count needed for balance, in plain language. It is the calculation most free truck-load calculators skip and the one that wins or loses a haul bid.

Volume vs Weight Binding Payload

Truck payload is the lesser of the heaped volume capacity and the weight-derived volume (legal payload / loose density). For light material the volume binds. For heavy material like wet clay (2,593 lb/LCY) or blasted rock (3,000 lb/LCY) the weight binds and the truck hauls light by volume. The tool picks the binding limit automatically, shows it in the verdict, and uses the correct payload through the rest of the cycle math. Estimating a wet-clay haul on volume alone is the single most common hauling mistake.

Cat PHB Material Library with Source Citations

Eleven material classes pulled from the Caterpillar Performance Handbook 49th edition Material Weight Conversion and Earthmoving Materials tables: topsoil, common earth dry and wet, clay dry and wet, sand dry and wet, gravel pit-run, crushed stone, rock blasted (well-fragmented), rock blasted (poorly-fragmented). Each carries the swell percentage, bank density, loose density, and bucket fill factor used by the engine. Every value has an inline source comment in the code; the methodology block in the PDF cites the catalog edition and section.

Loader Library with Cycle Time Defaults

Five loader classes (small wheel loader 1-3 yd, medium 3-5 yd, large 5-8 yd, track loader, hydraulic excavator face load) with default bucket capacities, cycle times, and hourly costs from Cat PHB. Selecting a loader pre-populates the three values; each is editable per project.

Trucks-Required Solver

The system computes the exact (fractional) truck count needed for match factor = 1.0, then offers the ceil-balance count (the integer just above the fractional value, accepting some truck queue) and the floor-balance count (just below, accepting some loader idle) as the practical integer alternatives. The truck-sizing table shows all three options side by side with the resulting match factor, so the user can pick the side they prefer based on which resource is more expensive to keep idle.

Fencing Production Rates with Modifiers

Nine fence types with baseline LF/crew-day rates from RSMeans 2024 Section 02 82 26. Six soil classes (loam baseline, sandy +5 percent, hard clay -15, rocky -45, frost -55, permafrost -70). Three terrain classes (flat baseline, rolling -15, steep -35). Three post methods (driven +25 percent, concrete-set baseline, rock-drilled -50). Crew-size scaling is sublinear (power-law exponent 0.7) reflecting workflow bottlenecks; a crew of 6 is faster than a crew of 3 but less than 2x faster. Height penalty kicks in above 6 ft (5 percent rate loss per ft).

Concrete Cure as Calendar Lag, Not Labor Time

When the post method is concrete-set, the tool reports concrete cure as calendar lag rather than labor time. On a short job (less than three labor-days) the cure forces a calendar gap. On a longer job the cure overlaps later work (the post crew is ahead of the fabric crew by the time the fabric crew arrives). The calendar duration is the right input for the schedule; the labor days are the right input for the crew dispatch.

Editable Company-Default Rate Library

The fencing base rates ship with RSMeans defaults but every rate is editable. When the user enters a custom base rate and clicks Save as Company Default, the rate persists to local storage per fence type. Next session it can be loaded with one click. Once an estimator tunes the rates to their own crews' production, the tool stops pretending to be a national-average estimate and becomes their estimate.

Permafrost and Frost Awareness for Alaska Work

The permafrost factor (0.30 vs loam baseline) and seasonal frost factor (0.45) are calibrated from Alaska DOT&PF construction productivity studies where steam thawing and rock drilling roughly triple the time per post. The tool also fires a warning flag if permafrost is selected with a non-rock-drilled post method, since the production rate alone does not capture the equipment requirement.

Material Takeoff as Optional Toggle, Not the Headline

Material takeoff is available as a toggle in the cost panel but is off by default. The headline is the production rate; material is a checkbox. This is the philosophical difference from a fence material calculator: those answer "how many posts and pickets" (which is commodity content), this answers "how long, how many crew-days, what cost per linear foot" (which wins bids). Both have their place. The Fence Material Calculator is the right tool for takeoff.
