How Multi-Pour Quantity Planner Works?

To plan several pours, the Multi-Pour Quantity Planner assigns piers to pour days or phases and totals concrete for each one. The process takes 4 steps.

  1. Create pours

    Name each pour by day or phase, such as “Day 1: north row.”

  2. Assign piers

    Add pier groups to each pour.

  3. Calculate each pour

    The planner totals cubic feet (ft³), cubic yards (yd³) and bags per pour, with waste.

  4. Review the schedule

    The tool lists each pour, the method that fits its size and the project total.

Multi-Pour Quantity Planner Formula

The Multi-Pour Quantity Planner groups piers by pour.

Pour volume

Vₚ = Σ nᵢ × π × (Dᵢ ÷ 24)² × (Hᵢ ÷ 12) × (1 + w)

Piers in pour p.

Project total

V = Σ Vₚ

All pours.

Pour bags

Bagsₚ = ⌈Vₚ ÷ Y⌉

Rounded per pour.

Worked example: Day 1 with 7 piers at 12 in × 48 in

  1. V₁ = 7 × 3.142 × 1.10 = 24.19 ft³
  2. 0.896 yd³ → 41 bags of 80 lb
  3. Day 1 fits a drum mixer pour with 2 workers

Multi-Pour Quantity Planner Conversion Table

The multi-pour conversion table shows a sample 3-day plan for a deck with a hot tub area, with 10% waste in each pour.

Rounding bags per pour adds a little surplus compared with one rounding for the project.

What is Multi-Pour Quantity Planner?

A Multi-Pour Quantity Planner is a scheduling tool that splits a pier job into planned pours and allocates concrete to each one.

Large decks and phased foundations rarely pour in one day. Inspections, weather and crew size break the work into parts. The planner gives each part its own order, so each delivery or store run matches the piers ready that day.

Per-pour totals help choose the method for each day: bags for a small day, a truck for a large one.

What are the uses of Multi-Pour Quantity Planner?

There are 4 main uses of the Multi-Pour Quantity Planner.

  • Phased decks

    Builders pour piers row by row.

  • Inspection staging

    Contractors pour after each inspected section.

  • Mixed methods

    Crews use bags on small days and trucks on large days.

  • Bag deliveries

    Owners split bag deliveries by pour day.
