City of Orono <br /> Project 614-059Q2 <br /> February 12, 2015 <br /> Page 2 i <br /> Visual Examination of the Field-Made Welds <br /> Visual examination of the field welds was conducted in accordance with Americah 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 I <br /> Tension-control bolted connection observations were conducted to determine if khe 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 er�d 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 contractor w�s determined using a <br /> hand-held torque wrench. In addition, each connection was observed for fit-up a�d 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 holes we�e 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 determine if the nuts were snug <br /> tight. This was done using a wrench and cheater bar. I <br /> Metal Deck Weld and Fastener Observations ' <br /> Metal deck weld observations were conducted in general accordance with AWS D�3-2008,Section 6.0 <br /> requirements and the requirements of the project plans and specifications. Items reviewed included the <br /> quality, size and spacing of the welds. In addition, the location and the completer�ess 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 use in the cold form <br /> metal-framing construction were placed in conformance with the requirements o�the structural details, <br /> plans and specifications. i <br />
