All excess cement must be removed. 829.04 METHOD OF MEASUREMENT. "Polyvinyl Chloride Scupper Piping" will be measured by the number of linear feet of each type of drainpipe actually installed in accordance with the Plans and/or as directed by the Engineer.
829.05 BASIS OF PAYMENT. The accepted quantities of "Polyvi nyl Chloride Scupper Piping" will
be paid for at their respective contract unit prices as listed in the Proposal. The prices so-stated constitute full and complete compensation for all labor, materials and equipment, including straps, hardware, bolts and all incidentals required to finish the work, complete and accepted by the Engineer.
830.01 DESCRIPTION. This work consists of the provision of any one of several types of bridge
rail at the locations indicated on the Plans or as directed by the Engineer, all in accordance with these Specifications. The types of railing cover ed by this provision are: Aluminum One-Bar Ornamental Rail; Steel Four-Bar Rail; Baldwin Four-Bar Ornamental Rail; and Steel Two-Bar Rail (Crash Tested). 830.02 MATERIALS. Materials for bridge railing shall conf orm to both the applicable provisions of SECTION M.05; METALS, of these Specifications and the following additional requirements.
830.02.1 Posts.
a.Aluminum Posts shall be shaped of cast aluminum fabricated from material which conforms to ASTM alloys A444.0-T4, A356.0-T61, or A356.0-T6.
b.Steel Posts for Steel Four-Bar Rail and Baldwin Four-Bar Ornamental Rail shall be wide flange sections which conform to the requirements of AASHTO M 270, Grade 36. 8−172 c. Steel Posts for the Two-Bar Rail (Crash Tested) shall be wide flange sections which conform to the requirements of AASHTO M233, Grade 50. 830.02.2 Rails.
a.Aluminum Rails shall be aluminum pipe fabricated from material which conforms to ASTM alloys 6061-T6, 6063-T6, or 6351-75.
b.Steel Rails for Steel Four-Bar Rail and Baldwin Four-Bar Ornamental Rail shall be either standard or extra strong steel pipe which c onforms to the requirements of ASTM A53, Grade B.
c.Steel Rails for Two-Bar Rail (Crash Tested) shall be hollow structural steel tubing which conforms to the requirements of ASTM A500, Grade B. 830.02.3 Plates.
a.Steel Plates shall conform to the requirements of AASHTO M270, Grade 36.
830.02.4 Anchor Bolts.
a.Anchor Bolts shall conform to the requirements of ASTM A307.
b.Threaded rods, nuts, and washers shall confor m to the requirements of AASHTO M164.
c.Anchor Bolt Assemblies shall be galvanized after fabrication in accordance with the requirements of AASHTO M111. 830.02.5 Galvanizing and Painting.
a.When specified on the Plans or in the Special Provisions, steel railing assemblies shall be galvanized in accordance with the requirements of AASHTO M111.
b.Fasteners including bolts, nuts, cap screws, washers and lock washers shall be galvanized in accordance with AASHTO M232.
c.Galvanized Railings shall either remain unpainted or painted as set forth on the Plans or Special Provisions. 830.03 CONSTRUCTION METHODS. The railings shall be accurately positioned at locations shown on the Plans. Posts shall be installed 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. The bases shall in general be mounted level by the use of lead shims unless otherwise designated on the Plans. Rails shall be installed in pieces of maximum practical lengths over several panels. Sequence of assembly to accomplish such continuity must be submitted with the shop drawings. 8−173The rail supports on posts shall be drafted or pitched to permit continuity of rails past the posts without cramping or crimping the rails. If rails are to be shop cut, positioning of anchor bolts must be checked in the field prior to cutting to establish rail lengths. Adjacent anchor bolts shall be trimmed as necessary to present a visual uniformity of grips. The anchor bolts shall extend or be trimmed to a proper grip for the nut. All aluminum faces to be installed in contact with concrete or dissimilar metal surface shall be heavily coated with an approved al uminum impregnated caulking com pound or zinc chromate paint. Alternatively, a synthetic rubber gasket may be placed between the two surfaces. 830.04 METHOD OF MEASUREMENT. "Aluminum One-Bar Ornamental Rail," "Steel Four-Bar Rail," "Baldwin Four-Bar Ornamental Rail," and "Steel Two-Bar Rail (Crash-Tested)" will be measured by the number of linear feet of each such type actually installed in accordance with the Plans and/or as directed by the Engineer.
830.05 BASIS OF PAYMENT. The accepted quantities of "Aluminum One-Bar Ornamental Rail,"
"Steel Four-Bar Rail," "Baldwin Four-Bar Ornamental Rail," and "Steel Two-Bar Rail (Crash- Tested)" will be paid for at their respective contract unit prices per linear foot as listed in the Proposal. The prices so-stated constitute full and complete compensation for all labor, materials and equipment, including anchor assemblies and all incidentals required to finish the work, complete and accepted by the Engineer.
