The elevated slabs at JC Penney Corporate Headquarters in Plano, Texas, are evidence of superior quality achieved by effective preconstruction planning and diligent monitoring during construction. The architect and engineer established reasonable tolerance expectations and provided sufficient information for the contractor to develop accurate pricing. Before construction the design-construction team and the floor consultant met several times. Contractor and floor consultant communicated daily during construction. The approach of planning, constructing and evaluating helped foster a feeling of teamwork and pride in the results.
