completed with the selection of shore and bracing
material that will safely support the vertical and lateral
loads. Each of these steps used in beam form design
can be accomplished by using the applicable
procedures discussed in the previous section on
overhead slab form design.
In chapter 2 we covered the procedures that good
estimators use to plan, estimate, and schedule projects.
In this section we will briefly cover labor estimates for
formwork according to the Seabee Planners and
Estimators Handbook, NAVFAC P-405. Figure 3-6
shows the labor chart from the P-405 which is
self-explanatory on how to estimate labor. To
calculate manpower estimates, you must first estimate
the square footage of contact surface (SFCS). After
estimating the SFCS of the work element, you then
need to determine the units (100 SFCS/unit).
