| Scenario | Area | Productivity | Factors | Crew & shift | Estimated labor-hours | Estimated duration |
|---|---|---|---|---|---|---|
| Open slab sweep | 18,000 ft² | 1,000 ft² per labor-hour | Surface 1.00, Access 1.00, Debris 1.00, Scope 0.80 | 3 workers, 8 h/day, 10% breaks | ~15.9 h | ~0.74 days |
| Congested detailed clean | 12,000 ft² | 850 ft² per labor-hour | Surface 1.15, Access 1.10, Debris 1.20, Scope 1.00 | 4 workers, 8 h/day, 10% breaks | ~24.1 h | ~0.84 days |
| Final turnover clean | 9,500 ft² | 700 ft² per labor-hour | Surface 1.30, Access 1.25, Debris 1.20, Scope 1.25 | 5 workers, 9 h/day, 12% breaks | ~44.2 h | ~1.11 days |
Before estimating hours, define what “clean” means for turnover. Separate sweeping, debris hauling, wipe-down, glass, fixtures, and restroom detailing. Quantify areas by zone and finish type, not only floor area. Include stairs, landings, handrails, and vertical surfaces when standards require them. Document exclusions like hazardous waste or paint removal. A clear scope prevents rework and stabilizes the estimate. Capture access restrictions and working hours in notes.
Productivity is best taken from recent, comparable projects. Track square footage cleaned per labor-hour by scope level and crew mix. Adjust for cleaning method, equipment, and disposal distance. If data is missing, start with conservative rates, then refine after the first shift using measured output. Avoid using “calendar hours” as productivity; the calculator expects labor-hours. Record assumptions for later audit. Weather can delay final cleaning significantly.
Condition factors translate base productivity into realistic field performance. Rough finishes, grout haze, and textured surfaces slow down passes. Congested rooms require repositioning tools and moving protection. Heavy debris adds handling time and increases bag counts. Scope factor differentiates a sweep from a final turnover clean with detailing. Apply factors consistently across zones, then validate by spot-checking one representative area with a timed trial on site.
Crew planning converts labor-hours into days and staffing. Use effective shift hours by subtracting breaks, meetings, and material runs. If the schedule is fixed, back-calculate the required crew and round up to protect milestones. Coordinate cleaning with punch lists so crews are not blocked by trades. Stagger zones to keep work continuous and reduce idle time. Update the plan daily using actuals. Improves forecasts for management.
Use the export buttons to create consistent records for bids, change orders, and closeout packages. Attach photos, zone maps, and standards references to the PDF for clarity. For cost checks, pair labor-hours with an approved blended rate and compare against budgets. When scope expands, revise area and factors rather than adding lump sums. A transparent model supports fair pricing and reduces disputes with clients and leadership.
Use a rate from recent, similar work with the same scope. If unsure, start conservative, measure one shift’s output, then update the rate for the remaining zones.
Each factor represents a proportional change in efficiency. Multiplying keeps the estimate scalable and consistent across zones, especially when several conditions affect the same base productivity.
Setup covers staging, bagging stations, and briefing. Rework covers touch-ups after trade work. Use historical ranges, then reduce them when the site is stable and protected.
Yes. Select m² for area and, if needed, for productivity basis. The calculator converts internally so the base labor-hours remain consistent across unit systems.
It reduces productive shift time per worker. That increases the calculated duration and crew needed for target days, which helps prevent optimistic schedules.
It is a labor-only check: total labor-hours multiplied by your hourly rate. For full pricing, add supervision, consumables, disposal, equipment, and contingency based on contract requirements.
