(1) Patented steel scaffold. Erect patented steel scaffolds by placing the first and second
uprights on footing plates and insert diagonal braces, thus completing the first set of tiers. The diagonal
braces have rapid locking end fittings (Figure 4-16) that permit rapid locking into position. The first-tier
set is set at ground level on steel bases. Erect the second-tier set by placing the third and fourth uprights
on footing plates and insert diagonal braces. Lock the second set to the first set with diagonal braces.
Elevate scaffolds by placing a second tier on the first tier, and lock the bottom of each upright to the top
of the lower tier. Build the scaffold as high as desired, but tie a high scaffold into the main structure
with building tie-ins (Figure 4-17, page 4-12).
