Central Washington University CHCI Assessment Report 12-10-13
urine was present on the surface of the concrete it was not identified at a depth of 1/16 to 1/8-inch or more into the concrete. DISCUSSION OF RESULTS . Mold Growth A limited amount of mold growth, ~ 6 square feet, was identified on lower GWB in the south wall Closet 104. The moisture that caused fungal growth in this area is most likely associated with the efflorescence that occurred in this location. The fact that the GWB was in direct contact with the concrete floor was likely a factor in wetting the lower GWB. EHSI recommends the removal and replacement of the lower GWB from this closet. Workers handling the mold-affected GWB should wear gloves and at least an N95 face mask. Removed materials should be double bagged prior to removal from the closet and building. Urine in Concrete Ultra-violet light evidence suggests that the chimpanzee enclosures were well-maintained in regards to flushing and daily removal of urine and other bodily fluids. Although the condition of concrete varies between night enclosures and day enclosures, the areas with the most likely urine staining are the bottoms of the floor trenches. Concrete below the surface does not fluoresce under ultra-violet light and consequently it is believed that urine did not penetrate deeply into concrete flooring. There was no fluoresce identified 1/16 to 1/8- inch below the surface of the concrete . SITE ACCESSABILITY The evaluation team observed the subject site accessibility as it relates to guidelines of the Americans with Disabilities Act (ADA) Standards for Accessible Design as revised as of September 15, 2010 (2010 ADA) and the WA State Building Code (2012 IBC with ICC/ANSI A117.1 2009) (referred to herein collectively as the “Listed Codes”). Areas observed included the parking area, the exterior pathway between the parking and building. General deficiencies in site accessibility and route of travel include: SITE ILLUMINATION AND SECURITY LIGHTING Site illumination at the main entrance walk is provided by pole luminaires. Site lighting along the east and north elevations is provided by building-mounted fixtures. majority of site lighting is operational and appears to meet the requirements of LFS 16520 although its operation to meet emergency egress is not known . SITE ELEMENTS
PARKING, SIDEWALKS, CURBS, CURB CUTS, AND WHEELSTOPS
Vehicular access to, from, and on site is on asphalt or concrete paving. The condition of paving is good to fair with cracks, and some settlement noted in the asphalt at the northeast corner of the access road. Paving
