A specialty concrete contractor under a design-build contract for a parking garage hired an engineering firm to  provide the structural specifications. Following construction, the garage owner noticed cracks in the support  columns. The cause was determined to be that the rebar specified in the engineering plan was insufficient to support  the structure. The cost to replace the rebar with appropriate materials was in excess of $140,000. As the contractor  hired the engineering firm under a design-build contract, the owner filed a lawsuit against the contractor for the  repairs and resulting business interruption losses.
