Concrete construction joint phasing calculator

Calculate workday plan [day,phase areas,spare area m²] and workdays used with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use workday plan [day,phase areas,spare area m²] and workdays used to compare changes to your inputs. The method and limits below explain the scope.

Workday plan [day,phase areas,spare area m²]
[[1,[["A",80]],40],[2,[["B",50],["C",60]],10]]

Calculation method

Calculation method

Workday plan [day,phase areas,spare area m²]

Preserve phase order; put each indivisible phase on current day if capacity permits, otherwise next day.

Workdays used

Number of nonempty days.

Oversize phases

Phases larger than supplied daily capacity; these require external redesign and are not split.

Symbols and units
a
JSON Approved pour phases in required order [ID,area m²]
b
Supplied available pour area per workday (m²)

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Assumptions & limits

Assumptions & limits

  • Pour phases already divided at approved joints, fixed order and identical user daily capacity. Sequential next-fit heuristic; no joint location, crew productivity or structural design inferred. Supported limits: 1–100 approved phases, positive areas/capacity.
