Dont be careless with bolts, nuts, and miscellane-
ous fasteners just because they are furnished in quan-
tities greater than actual requirements.Be careful
when using these fasteners to prevent scattering them
on the ground. Each evening, empty your pockets of
fasteners and other small parts before leaving the
An extra amount of mastic or sealant is also fur-
nished with each PEB. Here too, reasonable care in
applying mastic to roof panels and roof accessories
ensures an adequate supply.
Crating lumber can be used to construct an en-
trance platform and stairs at each end of a PEB. Figure
9-18 shows one way this might be done.
Disassembly of a preengineered building should
not be difficult once you are familiar with the erection
procedures. Basically, it involves accurately marking
the parts and following some basic steps.

Its obvious but worth repeating: In disassembling
a building, be sure to clearly mark or number all parts.
You will then know where the parts go when reassem-
bling the building.
There are five main steps in disassembling a PEB:
1. Remove hardboard liner panels.
2. Remove windows, door leaves, and end wall.
3. Remove diagonal brace angles and sag rods.
4. Remove braces, girts, and purlins.
5. Let down frames.
Handling of the building components during dis-
assembly is very important. You may have to reuse
these same components again at another location. As
you complete disassembly, protect those components
from damage. Any damaged components will have to
be replaced, and time might not be on your side.
LEARNING OBJECTIVE: Upon completing
this section, you should be able to identify the
characteristics of wood-frame tents, SEA huts,
and field-type latrines.
There are three basic types of wood-frame con-
struction of concern to Builders: tents with wood
frames for support; SEA huts (developed in Southeast
Asia during the Vietnam war); and field latrines.
Figure 9-19 shows working drawings for framing
and flooring of a 16- by 32-foot wood-frame tent,
Tents of this type are used for temporary housing,
storage, showers, washrooms, latrines, and utility
spaces at an advanced base.
Tent floors consist of floor joists (16-foot lengths
of 2 by 4s) and sheathing (4- by 8-foot sheets of
1/2-inch plywood). The supports for the floor framing
are doubled 2 by 4 posts anchored on 2 by 12 by 12
mudsills. The wall-framing members are 2 by 4 studs,
spaced 4-feet OC. The roof-framing members are 2 by
4 rafters, spaced 4-feet OC. The plates (2 by 4s) and
the bracing members (1 by 6s) are fabricated in the
field. A representative floor-framing plan for a
