This school was experiencing rapid growth in enrollment, leading to construction of classrooms, dorms and parking garages. This precast parking garage originally specified 6x6/2.9x2.9 wwf for the 5 inch slab-on-grade to control temperature and shrinkage cracking. The concrete contractor proposed using a macro synthetic alternative, Fibermesh® 650, to help reduce the possibility of cracking; an issue on prior garages on campus. A comprehensive product submittal was reviewed and approved by the structural engineer. Eliminating the wire mesh increased speed of construction and using fiber reinforcement ensured proper placement by providing three dimensional reinforcement throughout the thickness of the slab. The concrete was pumped and placed using standard practices and techniques. The surface received a broom finish, and saw cuts were done using a Soff-Cut 'early' entry saw with control joints cut approximately 15* on center each way.
