816.01 DESCRIPTION. Furnish and construct specified bridge deck drainage
system.
816.02 MATERIALS. Materials shall comply with the plans and specifications
and the following: Culverts and Storm Drains Manholes, Junction Boxes, Catch Basins, and End Treatments Bedding Material Structural Concrete Deformed Reinforcing Steel Structural Metals 701.02 702.02 726.02 805.02 806.02 807.02 Painting and Protective Coatings Section 811 Metals Section 1013 Stainless Steel Bolts 1013.08 Pipe hangers, scuppers and drain grates shall be steel conforming to ASTM A709, Grade 36, galvanized after fabrication in accordance with section 811. Bolts, nuts, and washers connecting drain grates and scuppers shall be stainless steel AISI Type 416. All other bolts, nuts, washers and screws shall conform to ASTM A 307, galvanized in accordance with ASTM A 153/A 153 M or by an approved mechanical galvanizing process conforming to ASTM B 695 that provides the same coating thickness. Piping and fittings shall be one of the following systems, at the contractor’s option:
1.Aboveground piping shall be standard weight, schedule 40, galvanized steel pipe conforming to ASTM A 53/A 53 M, and underground piping shall be cast iron pipe conforming to ASTM A 74; or,
2.All piping (both underground and above ground) shall be standard weight, schedule 40, galvanized, nickel-copper alloy steel pipe conforming to ASTM A 53/A 53 M, except the chemical composition shall include copper content from 0.75 to 1.25 percent by weight and nickel content from 1.60 to 2.20 percent by weight. When materials other than steel are specified, provide materials according to the plans.
816.03 Construction Requirements.
816.03.1 Submittals: Submit fabrication details to the Bridge Engineer for
review in accordance with Section 801. Do not order materials or begin work until submittal acceptance. Acceptance by the engineer will be subject to field performance and will not relieve the contractor of the responsibility to satisfactorily complete the work. As a minimum include the fabrication details, material and coating requirements, proposed piping layout, fittings and slopes, grating details, and anchor and hanger details.
816.03.2 Bridge Deck Drainage System: Fabricate in accordance with
the plans and specifications. Deviations will not be permitted without approval of the Bridge Engineer. Provide the DOTD Fabrication Engineer at least 30 calendar day advance written notice of t he beginning of work at the mill or shop so that inspection may be provided. No material shall be manufactured or work done in the shop before the DOTD Fabrication Engineer has been notified. Furnish facilities for inspection of materials and workmanship in the mill and shop as described in Section 807. Ends of pipe shall be smooth at welded joints; otherwise, pipe ends shall be grooved to facilitate mechanical type couplings. Pipe couplings shall be mechanical type, to mechanically engage and lock the groove pipe or fitting ends in a positive couple to allow for angular deflection and contraction and expansion. Each coupling shall consist of malleable iron housing clamps in two or more parts, a sealing gasket, and two or more steel bolts as required to assemble the housing clamps. Couplings shall be Victaulic Standard Couplings, Type 77, or Gustin Bacon No. 100 or other approved equal couplings. Exposed metalwork not galvanized shall be painted in accordance with Section 811. Damaged galvanizing shall be repaired in accordance with Section 811.
816.03.3 Bridge End Drain System: Construct bridge end drain system in
accordance with the plans. Comply with 0 for the placement of pipe. Comply with Section 702 for construction of the catch basin. Comply with Section 726 and
1003.10 for bedding material requirements.
816.04 Measurement.
816.04.1 Bridge Deck Drainage System: Bridge deck drainage systems
will be measured per lump sum. Any estimated quantities shown in the plans are approximate and no guarantee is made that those are the correct quantities to be furnished. No adjustments in contract price will be made due to errors in the estimated quantities shown on the plans. Shop bills will not be required.
816.04.2 Bridge End Drain System: Bridge end drain system will be
measured per each. Measurement for bridge end drain system will include all materials specified in the plans for the installation of the bridge end drain system.
816.05 PAYMENT. Payment for bridge deck drainage system and bridge end
drain system will include all materials, labor, equipment, tools, testing and incidentals necessary to complete the work. Payment will be made at the contract unit price under: Item No. Pay Item Pay Unit 816-01 Bridge Deck Drainage System (Type) Lump Sum 816-02 Bridge End Drain System (Type) Each
