City of Orono <br /> Project 814-059a2 <br /> February 12, 2015 <br /> Page 2 <br /> Visual Examination of the Field-Made Welds <br /> Visual examination of the field welds was conducted in accordance with American Welding Society <br /> (AWS) D1.1-2010, Figure 5.4 and Table 6.1 requirements and the requirements of the project plans and <br /> specifications. <br /> Tension-Control Bolted Connection Observations <br /> Tension-control bolted connection observations were conducted to deterrnine if the bolt holes were <br /> filled, if the correct bolts were used, if the nuts were fully engaged and if the splined end of the tension- <br /> control bolts had separated from the body of the bolt. Removal of the splined end is a direct indicator <br /> the bolt has been torqued to the minimum snap-off load. At connections where the splined ends were <br /> not, or could not be removed,the torque applied to the bolt by the contiractor was determined using a <br /> hand-held torque wrench. In addition, each connection was ok�served for fit-up and to determine if the <br /> various plies were in contact with one another. <br /> Hex-Head Bolted Connection Observations <br /> Hex-head bolting observations were performed to determine if the bolt hales were filled, if the correct <br /> bolts were used, if the nuts were fully engaged and if they appeared to be snug tight. Each hex-head <br /> bolted connection was observed for fit-up and to determine if the various plies were in contact with one <br /> another. Random bolts were also selected at various connections to detarmine if the nuts were snug <br /> tight. This was done using a wrench and cheater bar. <br /> Metal Deck Weld and Fastener Observations <br /> Metal deck weld observations were conducted in general accordance with AWS D1.3-2008, Section 6.0 <br /> requirements and the requirements of the project plans and specificatioris. Items reviewed included the <br /> quality, size and spacing of the welds. In addition,the location �and the cc�mpleteness of the side-lap <br /> fastener installation were observed and evaluated. <br /> Cold Form Metal-Framing Mechanical Fasteners <br /> Visual observations were conducted to determine if the mechanical fasteners used in the cold form <br /> metal-framing construction were placed in conformance with the require�ments of the structural details, <br /> plans and specifications. <br /> � ���� �.� � <br /> {���a;'- ��� <br />
