Special Inspection and Testing Procedures The special inspection services were periodically provided by International Code Council (ICC) certified special inspectors in accordance with the requirements of the Minnesota State Building Code, Chapter 1700 of the International Building Code (IBC) and the project plans and specifications. The purpose of special inspections is to provide a review of the contractor's work designated by the project structural engineer as needing special inspection under the guidelines of the IBC to determine compliance with the approved construction documents. The special inspector doesn't have the responsibility or authority to, nor is it the intent of special inspections to have them, judge or modify the construction documents. Only the structural engineer of record can do this. As the special inspections were completed, a Special Inspection Daily Report was prepared to summarize the results of our inspections and testing. A copy of this report was provided to the contractor's site representative for their review and records. As part of this report, items needing correction or discrepancies observed from the approved construction documents were noted. We also summarized the discrepancies documented in a Discrepancy Log. As needed, we also contacted the project structural engineer for additional clarification on specific issues related to the drawings or discrepancies observed. Plans and Specifications The plans and project documents available at the site were used for our inspections. From time to time, we received plan modifications from the structural engineer. When received, these were used to evaluate the work completed in the field. - Providing engineering and environmental solutions since 1957 Visual Examination of Field Welds Visual examination of the field welds was conducted in accordance with American Welding Society (AWS) D1.1 -2008, Figure 5.4 and Table 6.1 requirements and the requirements of the project plans and specifications. Hex -Head Bolted Connection Observations Hex -head bolting observations were performed to determine if the bolt holes were filled, if the correct bolts were used, if the nuts were fully engaged and if they appeared to be snug tight. Each hex -head bolted connection was observed for fit -up and to determine if the various plies were in contact with one another. Random bolts were also selected at various connections to determine if the nuts were snug tight. Metal Deck Weld Observations Metal deck weld observations were conducted in general accordance with AWS D1.3 -1998, Section 6.0 requirements and the requirements of the project plans and specifications. Items reviewed included the quality, size and spacing of the welds. In addition, the location and the completeness of the side lap fastener installation were observed and evaluated. Metal Deck Mechanical Fasteners Observations of the metal deck mechanical fasteners were completed to document the screw fasteners were installed as required in the construction documents and in accordance with the requirements of the manufacturer. Items noted were the placement and the depth of penetration. Drilled in Expansion Anchors Observations were preformed after the installation of the drilled in expansion anchors to determine if they were installed according to the project documents. Items observed included the placement, if the nuts were fully engaged, if the adjoining plies were in contact with one another and if the nuts were snug tight. Ultrasonic Examinations Diversified Construction Project BL- 10- 00403A November 29, 2010 Page 2 Ultrasonic examinations of the partial and full penetration welded connections 5/16's inches or greater were conducted in general accordance with the AWS D1.1- 2008, Section 6, Table 6.2 static loaded criteria and the requirements of the project plans and specifications.
