At the Contractor's expense, additional installation tension tests, tests required to determine job inspecting torque, and rotational capacity tests shall be performed by the Contractor on each rotational capacity lot, in the presence of the Engineer, if: 1. Any fastener is not used within 3 months arrival on the job site, 2. Fasteners are improperly handled, stored, or subjected to inclement weather prior to final tightening, 3. Significant changes are noted in original surface condition of threads, washers, or nut lubricant, or 4. The Contractor's required inspection is not performed within 48 hours after all fasteners in a joint have been tensioned. Failure of a jobsite installation tension test or a rotational capacity test will be cause for rejection of unused fasteners that are part of the rotational capacity lot. When direct tension indicators are used, installation verification tests shall be performed in conformance with Appendix Section X1.4 of ASTM Designation: F 959, except that bolts shall be initially tensioned to a value 5 percent greater than the minimum required bolt tension. SURFACE PREPARATION For all bolted connections, the contact surfaces and inside surfaces of bolt holes shall be cleaned and coated before assembly in conformance with the provisions for cleaning and painting structural steel of these special provisions. SURFACE PREPARATION For all bolted connections the following be cleaned and coated before assembly in conformance with the provisions for cleaning and painting structural steel of these special provisions: 1. Contact surfaces, 2. surfaces of existing members that are within the grip and will be hidden by surfaces of outside existing members within the grip under bolt heads, nuts, and washers, and 3. Inside surfaces of bolt holes. SURFACE PREPARATION For all bolted connections, the new contact surfaces and inside surfaces of bolt holes shall be cleaned and coated before assembly in conformance with the provisions for cleaning and painting structural steel of these special provisions.
