placed and cured sufficiently, the forms are removed piece by piece,
or in relatively small sections, and moved to another location in the
building where they are reassembled for additional uses. Following
this procedure results in considerable cost for labor. In addition, it
delays the completion of the project.
If flying deck forms are used, the forms are preassembled into
sections or modules at ground level, using labor-saving equipment
and methods. They are then moved (flown) into position for concreting.
Each deck module is located in its proper position, and its height
is adjusted to the correct elevation. Filler strips are then placed
between the deck modules. Reinforcing steel is placed, electrical and
plumbing components are installed, and any other services that are
required are performed. Then the concrete is placed.
When the concrete has attained sufficient strength, the flying deck
forms are lowered from beneath the newly placed concrete slab,
moved to the edge of the supporting concrete slab, and hoisted to a
higher level for reuse. The most recently placed concrete slab should
be reshored immediately before any loads are placed on it.
