Brian Kurtz, Kurtz & Assoc., Inc. 2. Rebar Crew 3. Saul Torres, Mayan Construction THE FOLLOWING WAS OBSERVED: Kurtz and Associates, Inc. is the structural engineer of record for the noted single family residence. As such, of office provided structural construction documents dated April 14, 2020 and a partial plan revision dated April 29, 2020. The purpose of this inspection was to observe formwork and reinforcement for the foundation walls. At this time all of the foundation wall reinforcement was in place. At this time the formwork for the `frost' walls at the garage wing was complete. The formwork for the crawl space walls was close to completion. At this time the formwork was in place on one face of the basement walls: the rebar crew was beginning to place the second face of the formwork while I was on site. Wall reinforcement was essentially complete at the time of the inspection. I took care to review the footing - to -wall dowels at the `frost' walls at the garage wing and the crawl space beneath the master bedroom. These dowels had been `stabbed' after the concrete footings had been poured. The dowels were of the correct length and spacing, and were, almost universally, clean of concrete scale. The dowels were specified as No. 4 dowels at 16" on center. No. 5 rebar had been substituted on a one to one basis for the dowels and the wall reinforcement at the `frost' walls. This substitution is structurally acceptable. Wall reinforcement for the `frost' walls was accurately placed as specified and corner bars were placed and properly tied to the wall reinforcement as specified. The construction documents specified that the reinforcement for the continuous basement walls be a single mat of No. 5 rebar spaced at 12" on center horizontal and vertical. For the `deep' crawl space walls beneath the kitchen and living room the reinforcement was specified to be a single mat of No. 5 rebar spaced at 16" wide on center horizontal and vertical. In each of these cases the rebar mat was placed at the center of the 8" wall as specified. The wall reinforcement in these two conditions was accurately placed as 2 specified and corner bars were placed and properly tied as specified. I noted a single dowel (at the north side of the basement) which was misplaced. This single misplaced dowel is not structurally detrimental. The wall reinforcement was clean, and the bottom of the wall forms were free of deleterious material. At this time the wall reinforcement placement is complete and is in accordance with the structural construction documents.
