A form was built by Rupp Family Construction to accommodate a concrete slab of approximately 14 feet wide, by 30 feet long, and 2 feet tall. Due to the nature of the project, it was imperative that the dimensions of the concrete slab fall within somewhat exacting tolerances.

About halfway through the pour the form began to fail -- the north, south, and east sides began to bulge outwards. There was a frantic rush to scavenge material to shore up the sides that were failing, but ultimately the north and south sides bulged up to 1 and 1/2 inches out of specifications. Also, the surface of the concrete pad -- rather than being reasonably even overall -- had pronounced gouges and troughs in several places, some as deep as 3/8 inches relative to areas immediately adjacent (within 2 to 3 inches away).

Rupp Family Construction agreed to pour an additional 3 and 1/2 inches of fiberglass reinforced concrete on top of the surface of the original concrete slab.

A few weeks later a concrete contractor came out to inspect the concrete slab (the original slab with its concrete cap) poured by Rupp Family Construction. That contractor commented that, considering the amount of concrete needed for a slab of this size, he would have used adjustable, turnbuckle-style braces as support for the form walls rather than using only wooden stakes. If adjustable braces had been used during the original pour of concrete then the form walls could probably have been readjusted on-the-fly and immediately brought back into the proper shape.
