Provide a dditional material, at no additional cost to the Department, to keep both temporary and final stresses within the allowable limits used in design. Provide temporary bracing or stiffening devices to accommodate handling stresses in individual members or segments of the structure during erection. Use wind loads and distribution of wind loads to girders according to AASHTO Guide Specifications for Wind Loads on Bridges During Construction.

4.a General. This work consists of furnishing and installing bridge bearings. Bearing types include, but are not limited to, elastomeric pad, rocker, roller, pot, spherical, disk, and sliding plate bearings. Included as components of bearings are masonry, sole and shim plates, bronze or copper -alloyed bearing and expansion plates, anchor bolts, PTFE sheets or surfacing, lubricants and adhesives. The furnishing and installation of bedding materials used under masonry plates is also included in this work. Construct bearings according to the indicated details. If complete details are not provided, furnish bearings that conform to the limited, indicated details and provide the design capacities for loads and movements shown or specified and the performance characteristics specified.
4.a.1 Working Drawings. If complete details for bearings and their anchorages are not indicated, prepare and submit working drawings for the bearings. Show all details of the bearings and of the materials proposed for use on such drawings, and have the drawings approved before fabrication of
