How Planned vs Actual Concrete Tracker Works?

To track variance, the Planned vs Actual Concrete Tracker records the concrete used on each pour and compares it with the estimate. The process takes 4 steps.

  1. Load the plan

    Import planned volumes or bags per pour or pier group.

  2. Record actuals

    Type the bags mixed or the yards on each delivery ticket after each pour.

  3. Compare

    The tracker computes the difference and the percent variance.

  4. Review trends

    The tool flags groups over 10% and shows the running project variance.

Planned vs Actual Concrete Tracker Formula

The Planned vs Actual Concrete Tracker uses variance math.

Variance

Δ = Actual − Planned

Positive means more concrete used.

Percent

Δ% = Δ ÷ Planned × 100%

Size of the miss.

Running total

Δ_project = Σ Actual − Σ Planned

Across all pours.

Worked example: hot tub piers, 4 at 16 in × 48 in

  1. Planned = ⌈22.34 ÷ 0.60⌉ = 38 bags
  2. Actual = 44 bags from the pour log
  3. Δ = +6 bags (+16%), so the holes were over-dug

What is Planned vs Actual Concrete Tracker?

A Planned vs Actual Concrete Tracker is a job-tracking tool that compares estimated concrete with recorded use to measure material variance.

Estimates improve when they are checked. A crew that logs bags per group learns where holes run wide, which soil causes over-dig and which waste margin fits. A 16% overrun on wide hot tub piers says the auger wandered or the soil caved.

The tracker turns a pour log into a waste margin for the next job.

What are the uses of Planned vs Actual Concrete Tracker?

There are 4 main uses of the Planned vs Actual Concrete Tracker.

  • Waste calibration

    Estimators set margins from real data.

  • Ticket checks

    Contractors match delivery tickets to the plan.

  • Crew feedback

    Supervisors spot over-digging by crew or site.

  • Job closeout

    Offices record final concrete use.
