Figure 3-6. - Formwork labor chart.

For example, if you estimated 800 square feet of contact surface, then it is only a matter of dividing 800by 100, which equals 8 units. Now you enter the column for estimating man-hours per unit and you will see four separate columns: fabricate, erect, strip, andrepair. Its just a matter of what scope of work you are performing and multiplying the work element by the scope of work.

You have just finished estimating 800 square feet of contact surface for your foundation wall and now you need to fabricate the formwork. To determine the man-hours required, just multiply the number of units (8) by man-hours per unit (9), which equals 72 man-hours. To find man-days, you would divide 72 man-hours by the number of hours you work in 1 day (determined by your unit) normally 8 hours per day, which will equal 9 duration days per person. So if you
