SECTION 830 — METAL BRIDGE RAILING — METAL BRIDGE RAILING
830.01 Description.
This work includes the provision for metal bridge rail at the required locations. Ensure that all bridge rails are constructed according to the RIDOT Standard Details.
830.02 Materials.
Use materials for bridge railing that conform to SECTION M05 and the RIDOT Standard Details. Galvanizing, Metalizing, and Painting. For the following, use either metalizing or galvanizing and painting:
a.Steel Railing Assemblies. When specified on the Plans or in the Special Provisions, use steel railing assemblies that have been metalized according to SECTION 827 or galvanized according to SECTION 843. Ensure that hollow section railings are hot dip galvanized.
b.Fas teners . Use f asteners including bolts, nuts, cap screws, washers , and lock washers that have been galvanized according to AASHTO M232.
c.G alvanized Railings. Galvanized railings may either remain unpainted or painted as set forth on the Plans or Special Provisions.
830.03 Construction Methods.
Submit Shop Drawings to the Engineer, which shall include the sequence of assembly. Install posts vertical in the longitudinal plane of the bridge, except that, if no part of the rail has a gradient greater than 1½ percent, the posts may be mounted normal to the slope. Mount the bases in general level by using lead shims. Install rails in the maximum practical lengths over several panels. Ensure that the Shop Drawings present the sequence of assembly to accomplish the necessary continuity. Draft or pitch the rail supports on posts to permit continuity of rails past the posts without cramping or crimping the rails. If rails will be shop cut, check the positioning of anchor bolts in the field before cutting to establish rail lengths. As necessary, trim adjacent anchor bolts to present a visual uniformity of grips. Extend or trim the anchor bolts to a proper grip for the nut.
830.04 Method of Measurement.
Metal Bridge Railing will be measured by the number of linear feet of each such type installed.
830.05 Basis of Payment.
The Department will pay for the completed and accepted quantities as follows.
