How to Use This Calculator

Enter the total number of frames, lifts (tiers), cross braces, and planks/decks.
Set crew size (number of workers).
Review erection labor hours and days based on standard production rates.
Check dismantling hours (typically 60-70% of erection time) and total project labor hours.
Add safety inspection time and material handling time to your crew scheduling plan.

How the result changes with Total frames

Total frames	Erection labor-hours	Total labor-hours (erect + dismantle)
201	136.9	226
701	458.2	756
1,300	843.1	1,391
1,800	1,164.3	1,921.1

Total frames: Total number of scaffold end frames to erect.
Number of lifts (tiers): Vertical tiers of scaffold. Upper lifts take longer due to hoisting.
Cross braces: Number of X-braces to install.
Planks / decks: Number of scaffold planks to place.
Crew size (workers): Number of scaffold erectors. Minimum 2 per OSHA.
Total scaffold height (ft): Height determines if a hoisting premium applies (>40 ft: +20%, >80 ft: +40%).

Erection labor-hours: Total labor-hours to erect the scaffold.
Dismantle labor-hours: Estimated labor-hours to dismantle (65% of erection).
Total labor-hours (erect + dismantle): Combined erection and dismantling labor.
Erection calendar days: Working days to erect based on crew size and 8-hour days.
Dismantle calendar days: Working days to dismantle based on crew size.
Hours per frame (erection): Average labor-hours per frame including all components.

Identify Input Parameters
4 parameters
Total frames = 40, Number of lifts (tiers) = 4, Cross braces = 60, Planks / decks = 20 = 6 input(s) provided
Calculate Erection labor-hours
Erection labor-hours = (frameLaborHours + braceLaborHours + plankLaborHours + guardrailHours) * heig...
33.5 = 33.5
Calculate Total labor-hours
Total labor-hours = totalErectionHours + dismantleHours
55.3 = 55.3
Calculate Dismantle labor-hours
Dismantle labor-hours = totalErectionHours * 0.65
21.8 = 21.8
Calculate Erection calendar days
Erection calendar days = totalErectionHours / (crewSize * 8)
1 = 1
