ITEM 508 FALSEWORK AND FORMS
508.01 Description. This work consist of designing and building of falsework
and forms for the purpose of holding concrete in place until it has set up.
508.02 Falsework. Provide substantial and rigid falsework that does not
unduly obstruct any waterway, highway, or railway. Arrange intermediate
supports in the completed structure to produce the camber necessary to conform to
the plan profile of the roadway.
Do not allow the maximum deflection in the longitudinal falsework members at
the edges of the concrete deck to exceed 1/2 inch (13 mm) or the amount obtained
by the following formula, whichever is greater.
where:
+ 100
=
1000
S
d
304
S + 2540
d =
1000
d = the maximum deflection in inches (millimeters)
S = the distance between supports in inches (millimeters)
For transverse falsework members, and for longitudinal falsework members
other than those near the edges of the deck, increase the permissible deflection
obtained from the above formula by 75 percent.
