C. Production Rates and Crew Sizes
Depending on the type of floor being installed and general conditions at the job site, the minimum average production rates for each man per day should be as follows:
| Description | Approximate Rate |
|---|---|
| Material handling (once material is stored in or adjacent to work area) | 5000 sq. ft. per man per day |
| A/F field area | 350 sq. ft. per man per day |
| Perimeter cutting | 80 lin. ft. per man per day |
| Ramp | 1 ea. per man per day |
| Handrail (wall-mounted) | 60 lin. ft. per man per day |
| Handrail (floor-mounted) | 24 lin. ft. per man per day |
| Cutout with trim | 15 ea. per man per day |
| Round Hole (grommet) | 50 ea. per man per day |
| Fascia | 120 lin. ft. per man per day |
| Plenum divider | 120 lin. ft. per man per day |
If a loading dock is available, a 40-foot tractor trailer can be unloaded in two hours by two men using two pallet jacks. Moving the material to the area receiving the A/F installation depends on the distance from the loading dock and on having a clear path to move the material.
Where an outside hoist or Hi-Boy forklift is used because there is no loading dock, it may take four men four hours to unload a tractor trailer of material.
The size of a crew is affected by various factors that are unique to each project. Examples of these are: size of the area to be installed; availability of the work area in combination with other trades; distance of moving material from storage to area; having continuous flow of work without stoppages in project construction schedule. If these types of extraneous factors are not a consideration, then normal crew sizes for effective productivity rates in a given room area can be evaluated on the basis of the following square footages:
| Square footage | Working foremen | Mechanic | Apprentice |
|---|---|---|---|
| Up to 1,000 | 1 | 1 | 0 |
| 1,000 to 3,000 | 1 | 1 | 1 |
| 3,000 to 5,000 | 1 | 1 | 2 |
| 5,000 to 10,000 | 1 | 2 | 2 |
| 10,000 to 20,000 | 1 | 3 | 4 |
| 20,000 to 40,000 | 1 | 4 | 6 |
| 40,000 and up | Split crews by sizes and sequences of areas to be installed, plus a general foreman if needed to coordinate several floors simultaneously. | ||
