515.2 Materials
1.Furnish materials conforming to the following: Concrete ...................................................... ................................................................................................... 501 Paint ......................................................... ...................................................................................................... 517
2.All steel in steel grid floors shall conform to ASTM A36 , with a minimum copper content of 0.2 percent.
3.Zinc coat open type grid floors according to ASTM A123 .
4.For concrete filled type floors , use grade C, C-FA, C-S, C-IS, C-IP, or C-IT concrete. Provide QMP for class I structure concrete as specified in 715.
515.3 Construction
515.3.1 Fabrication
1.Manufacture the steel grid floors to conform to the thickness, section, loading, and other requirements the plans show; and so if assembled in place they conform to the camber the plans show. The engineer will reject steel grid floors not within 1/2 inch of s pecified camber. Serrate the top edges of open type grid floors.
2.If fabricating the floor with t he main elements normal to the centerline of the roadway, extend the units the full width of the roadway for roadways up to 40 feet wide. If multiple units are allowed, extend the units over at least 3 panels. If t he main elements are parallel to the centerline of the roadway, extend the section over no t less than 3 panels. If j oints are required , weld the ends of all main floor members at the joints over their full cr oss-sectional area to provide full continuity and, preferably, place joints, if assembling the floor in place, over a supporting member.
3.Before fabricating, submit complete detailed shop drawings to the engineer for approval. These drawings shall show the spacin g and size of component parts, th e size and length of welds, splices and trims, and complete assembly details, including size and lo cation of recommended erection welding.
4.Fabricate and construct steel grid floors being filled with co ncrete to provide adequate support for the concrete filler.
515.3.2 Erection
1.Assemble the units or sections of the grid floor on the struct ure and weld the abutting main elements and connecting members between the sections to provide full con tinuity for the entire floor or between any points the plans show. Weight the floor assembly down or cl amp it in place to make a tight joint with full bearing on its supports before welding. If there is a roadway crown, weld beveled bars to the stringer flange to provide a bearing surface parallel to the cr own, unless placing the stringers with their vertical axes normal to the crow n. Use the location, size, and length of the welds that the manufacturer recommends or as the engineer approves.
515.3.3 Welding
1.Weld steel grid floors as the plans show and conforming to AWS D 1.1, Structural Welding Code - Steel.
515.3.4 Painting
1.Spot paint damaged places in the zinc coating and field welds with a department-approved zinc-rich paint. Clean field welds of sca le or slag and neutralize the welds as specified in 517.3.1.3.1 before spot painting. 515.3.5 Concrete Filler
1.Mix, place, and cure the c oncrete as specified in 501 and 502. Unless directed otherwise, compact the concrete thoroughly by vibrating. The vibrating device and mann er of operation are subject to the engineer’s approval.
515.4 Measurement
1.The department will measure the St eel Grid Floor bid items by the square foot acceptably completed.
