432.03 Construction

432.03.01 Storage and Handling. Store all types of bearings at the site under cover and on

suitable blocking or platform at least 4 in. above all types of surfaces and vegetation. Protect from damage at all times and, when placed, keep them dry, clean, free of dirt, oil, grease, and other foreign substances.

432.03.02 Installation. Place preformed fabric pad on surfaces meeting 420.03.07(c) prior to

installing the masonry bearing plate. Ensure that all bearings and pedestals of truss, stringer spans, and the center and end bearing of swing spans are rigidly and permanently located to correct alignments and elevations. Refer to the applicable portions of Section 430 for the attachment of bearings or plates to steel superstructures. For bearing retrofit and replacement projects, inspect anchor bolts for deterioration and structural integrity at each existing beam end to be jacked. Only remove and replace those anchor bolts as indicated in the Contract Documents or designated by the Engineer. Use anchor bolts of the same diameter and length as the existing or as detailed in the Contract Documents. 2025 STANDARD SPECIFICATIONS FOR CONSTRUCTION AND MATERIALS
