BELLE AVE PARKING GARAGE <br />SAI ~89059 <br />Page 2 <br /> <br />CONDITION APPRAiSAr, <br /> <br />Roof Level <br /> <br />The roofing is weathered an~.deteriorated. Roofing at expansion <br />joints has buckled and cracked (see photo ~1). Standing water <br />was observed at the expansion joints and at some curb locations <br />(see photo ~2). The top surfac~ of t_he concrete could not be ob- <br />served therefore, its condition could not be ascertained. The <br />underside of the 'roof level showed numerous leaching stains <br />through cracks primarily in the 6 1/2" slab areas.and in the <br />post-tensioned flange tees in the east and west driving aisles. <br />Expansion joints show major leakage to levels below. Tee beam <br />stems exhibited some narrow cracks with leaching but concrete ap- <br />peared solid. Embedded steel at end bearing of stem~ showed some <br />surface rusting. ~. <br /> <br />SUPPORTED LEVELS 2-5 <br /> <br />Typical supported levels 2 through 5 all exhibited similar condi- <br />tions. Top of slab surface typically exhibits some weathering <br />(see photo ~4). The ~upper'5th level has some asphalt topping, <br />old concrete patching and random tarred areas. The majority of <br />sawed control joints in slab had loose or missing caulking. Some <br />troughs had been cut into the topping slab to divert water to <br />ramps. Expansion joints are generally torn and leaking with <br />backer material hanging loose from slab. Underside of 6 1/2, <br />slab and tee flange showed some evidence of leaching through <br />tight cracks in driving aisle. .Leaching at under surface of <br />slabs and tees decreased from upper to lower'most levels. Leach- <br />ing appears to be caused by frequent water migrations through <br />cracks in slab. As water migrated through it carried along part <br />of the cementing constituents depositing them as a white film, <br />stain or stalactites on the underside. At least (5) post- <br />tensioned concrete tee beams were found to have significant <br />cracks in the bottom of the stems over various lengths of the <br />span (see photo ~5). A few' s~alls were observed in the underside <br />of flange and sides of tee beam, their depths .did not seem to be <br />significant. Some spalls and steel plate corrosion at beam bear- <br />ings (see photo ~6), were als° observed but were not widespread <br />and appeared not to effect'proper load transfer to column bear- <br />ing. Many tee beam stems appeared to be offset by varying dis- <br />tances from the coi~{mn centerline. .No apparent distress was <br />noticed, therefore, it appears to be the original position. <br /> <br />A-7 <br /> <br /> <br />
