The subject canopies are located at the Everett Marina <br /> Building project in Everett, WA. One canopy is installed above the south entrance to the <br /> building and the other above the east entrance. The inspection was performed according to <br /> AWS D1.1 (2020), specifically focused on the contents in Table 8.1 (Visual Inspection <br /> Acceptance Criteria). <br /> KIE was provided drawings by Kingworks Structural Engineers for the design of the <br /> canopies structures. The inspection was performed on the welded connections between the <br /> L4x3xl/4 angle iron and the Hollow Structural Sections (HSS 8x6x3/16)used to form the <br /> main structure of the canopies. Each canopy has an upper and lower HSS member. Each <br /> member connects on both sides, top and bottom by the welded angle iron connection. <br /> According to the design drawings, the angle iron was secured to the columns using A307 <br /> through bolts. According to the drawings all welded connections were to be 3/16" fillet <br /> welds between the HSS members and the angle iron. <br /> In addition to the welding inspection, KIE reviewed material documentation and <br /> documentation provided by the erector/welder. The MTR's provided shows the angle iron <br /> was multigrade ASTM A36,A529 Gr 50,A572 Gr50 ASTM A709 RG 36/50. The tubing <br /> used states that it is ASTM A500 GR B/C. The welder stated that the manufacturers <br /> recommendations were used for the welding and provided specifications and the welder is <br /> WABO AWS D1.1 certified. The process was Flux Core Arc Welding (FCAW) with E71T <br /> filler material used(AWS A5.20).All joints were stated to be fit up per AWS standards.No <br /> 11520 42"a Ave South•Tukwila,WA 98168•206-455-5121 •kentengineering.com <br />
