Andover, MA Contractor Landmark Structures Corp. SUMMARY: A visit was made to the above referenced project for the purpose of performing a visual inspection of the field welded and bolted connections at the erected structural steel members for the second floor. Today's inspection consisted of the following activities and observations: Structural Steel, lines 1 from 1 to 12: 1. The visual inspection of the ASTM A325 3/4" TC type field bolted connections revealed the following locations to contain loose connections, requiring tensioning: the F/1 columns from the first to the third floors. 2. The visual inspection of the metal deck installation revealed complete installation with the specified fastening pattern observed throughout the inspected area. Side laps were found to be secured as specified, and complete. 3. Visual inspection of welds and moment welds from floor level appeared acceptable. 4. From floors 2 to 3 bolts, nuts, and washers were installed and found acceptable. 5. Brace framing is welded as per drawing. Existing Building: 1.
