Item A - Concrete Deterioration at Exterior Beams ● Various degrees of concrete cracking, spalling, and deterioration were observed on some of the exposed surfaces of the exterior concrete columns and beams around the fieldhouse. Most of the spalled concrete has been caused by corrosion of the reinforcing steel in the bottom of the exposed low beams. The cracking observed in some beam bottoms is an early indicator of corrosion of the reinforcing within. The cracking and spalling extend into some column faces. There are isolated areas where the exposed slab soffit also has areas of cracking or eminent spalling. Item B - Isolated Cracking in Beam-Column Joints ● Vertical cracking was observed in several beam-column joints at the roof level and low beams. Some horizontal cracks were also observed in the joint at the low beams. The crack widths are small and well-controlled by the reinforcing in the beams. The crack widths ranged from hairline to the thickness of a credit card. Not all cracks were observed closely, some may be the result of paint or finish on the concrete elements. Item C - Isolated Cracking in Decorative CMU Veneer Infill ● Vertical and stairstep cracking was observed in some of the decorative CMU infill panels between the low beams and the high roof beams. This cracking is primarily located near the building corners on the south and east sides of the structure. ● The mortar joint between the CMU veneer and the concrete elements has deteriorated in some locations. Similarly, the joint between the interior CMU and the sides of columns and bottoms of beams has deteriorated in a handful of locations. ● The CMU mechanical exhaust stack on the west side of the building has substantial stairstep cracking and washed out mortar joints on all three visible sides. Item D - Indications of Deteriorated Exterior Finish (Paint) ● There are some locations of deteriorated finish on the concrete members that may coincide with additional cracking in the member below or construction joints. ● Some areas of finish on the exterior concrete and CMU members are also weathered and deteriorated. Item E - Joist Seats ● While reviewing the interior surfaces of the CMU above the low beams, it was observed that two roof joist seat bearing angles were not flush to the side of the high roof beams. Item F - Trip Hazards ● A portion of the slab-on-grade near the southwest entrance to the fieldhouse has settled relative to other slabs. A sidewalk panel on the northeast side of the building has a similar, though less severe, offset.
