Estimating in Building Construction

160 CHAPTER THIRTEEN

5.Additional studs are also required on the gable ends of
the building (Figure 13.33), which will have to be
framed with studs between the double top plate and
the rafter unless trusses are used (Section 13–10). The
specifications and elevations should be checked to
determine whether the gable end is plain or has a
louver.
Estimating the studs for each gable end is accomplished
by first drawing a sketch of the gable end and by noting its
size (Figure 13.34). Find the number of studs required by
dividing the length by the stud spacing. Then, from the
sketch find the approximate average height of the stud
required and record the information on the workup sheet.
Multiply the quantity by two since there are two gable ends
on this building (Figure 13.35).

Quantity must be doubled to compensate for the gable ends at both

ends of the building. Each 10stud will produce an average of five

studs for the gable ends.

Headers. Headers are required to support the weight

of the building over the openings. A check of the specifi-

cations and drawings must be made to determine whether

the headers required are solid wood, headers and cripples,

or plywood headers (Figure 13.36). For ease of construc-

tion, many carpenters and home builders feel that a solid

header provides best results and they use 2 12s as head-

ers throughout the project, even in nonload-bearing

walls. Shortages and higher costs of materials have

increased the usage of plywood and smaller size headers.
