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 Planner's and Estimator's 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).Continue Reading
