Brian Kurtz, Kurtz & Assoc., Inc. 2. Rebar Crew 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. Our office issued a revision for the crawl space below the kitchen wing of the house dated April 29, 2020. The proposed residence consists of a structure made up of three primary wings, and the wings are connected with two relatively narrow connecting links. The living room plus master bedroom wing is constructed over a crawl space. The garage wing has a concrete slab on grade floor. The kitchen/dining and bedroom wing is constructed over a walk -out basement. The foundation system uses continuous cast in place concrete walls and footings for the perimeter of each wing and connecting link. The purpose of this inspection was to observe footing formwork, footing sizes and reinforcement for a majority of the structure. I had visited the site earlier in the day, at approximately 8:30 am. Saul Torres and Jim Wilson of Garfield County were present at that time. It was apparent at that time that the placement of reinforcement was not complete. At the time of the 4 pm inspection the formwork for the perimeter of the building was complete. All of the footing reinforcement was in place and a majority of the footing -to -wall dowels were in place. At the garage wing and the at the `frost' walls of the walk -out basement the footing -to -wall dowels were to be `stabbed' into the footings after the footing concrete had been placed. This is structurally acceptable in that those dowels are specified to be placed at the center of the 8" walls. 1 inspected the perimeter footings throughout the structure. The footing sizes and reinforcement were in place as specified on the construction documents: footing reinforcement and dowels were of the size and spacing as specified. Interior footings and exterior isolated deck support footings were not to be placed at this time. The dowels and reinforcement were clean, and the bottom of the footing form was free of deleterious material. At this time the footing formwork and dowel and reinforcement placement is complete and is in accordance with the structural construction documents. The construction documents specified various footing widths and reinforcement based upon the various conditions. The soils engineer of record (H-P/Kumar) had, upon inspecting the excavation, revised their 2 original recommendation with respect to over -excavation and placement of structural fill so that the depth of the over -excavation was increase to expose the underlying granular bearing soils. As a consequence of this revision the footing bearing elevations were lowered 3 feet to 5 feet in the crawl spaces below the kitchen and living room. Our office issued a partial foundation plan and detail (04/29/20) for the kitchen wing to address this situation. The footing sizes and reinforcement were increased to accommodate the increase foundation wall height. The reinforcement at the northeast and southwest sides of the crawl space beneath the living room was also increase in the same manner. The perimeter footings of these two crawl spaces were constructed in accordance with those revisions. • 4 c' 2p V r �• O '4014.
