    Concrete slab form work removal with limited vertical clearance

    I agree that inspecting the concrete slab (1'-3" thick, no beams) from underneath would not be possible with the metal deck forms in place. However, the metal deck forms should be designed to resist the loads without any temporary supports underneath while the plywood forms would be designed...

    Concrete slab form work removal with limited vertical clearance

    The only disadvantage I see with leaving the plywood forms in place is that we would not be able to inspect/check the slab from underneath. Would you see this as a problem?

    Concrete slab form work removal with limited vertical clearance

    The slab will be accessible after construction, since it will have walls on three sides only. We considered using metal deck forms to leave the forms in place, but the options are limited for the 20'-0" spans. The cost as Teguci said is much higher, about $14/sq.ft vs. $2/sq. ft for shorter...

    I appreciate your input, SlideRuleEra. It is good to know that 4'-3" sounds adequate for construction.

    Concrete slab form work removal with limited vertical clearance

    I do not have any construction information at this point since the project is at the final design phase now and has not gone out to bid yet. From the design point of view, the platform slab will be supported by concrete spread footings and walls that will be poured first. The contractor will...

    Concrete slab form work removal with limited vertical clearance

    I am working on a concrete platform project that may have a construction issue due to the limited vertical clearance available to remove the form work for the proposed cast-in-place (CIP) slab. The slab will be between 12 ft to 25 ft in width and the span length varies between 10 ft to 20 ft in...
