SP00594 (2015 Specifications: 05-01-16) (This Section requires SP00290. Requires SP00084 when a coating system warranty is required in subsection .75. Requires SP00296 when lead is anticipated.) SECTION 00594 - PREPARING AND COATING METAL STRUCTURES (Follow all instructions. If there are no instructions above a subsection, paragraph, sentence, or bullet, then include them in the project. The specifications may be modified to include project specific specifications, but all additions, deletions, or modifications must be sent to the ODOT Technical Resource and Senior Specifications Engineer for review and approval.) (Use only one of the following lead-in paragraphs as instructed below.) [ Use the following lead-in paragraph when NONE of the following subsections are included in the project special provisions. ] Comply with Section 00594 of the Standard Specifications. [ Use the following lead-in paragraph when ANY of the following subsections are included in the project special provisions. ] Comply with Section of the Standard Specifications modified as follows: (Use the following subsection .05(a) when lead is anticipated on the project.) - Add the following bullet to the end of the bullet list: 00594.05(a) Abrasive Blast Cleaning Type E1 Airlock for containment entryways. (Use the following subsection .05(g) when the Contractor is allowed to conform to defined loading conditions instead of submitting structural design calculations. Obtain language from the Bridge Designer.) 00594.05(g) Structural Design Requirements - Replace this subsection with the following subsection: 00594.05(g) Structural Design Requirements: (1) Design Requirements - Include dead load, live load, and wind load when designing loads for containment structures and work platforms. Dead load is the self-weight of the containment and work platforms, live load is all personnel, equipment, and materials, including collected debris, required for normal operations, and wind load is a basic wind speed of 90 mph applied in the most critical direction. Design a factor of safety of at least 6 for wire ropes and connecting hardware and at least 4 for all other components for containment structure and work platform
