19 -- DEBRIS BOOM AND BOAT RESTRAINING BARRIERS SOL 1425-97-SQ-10-00390 DUE 082297 POC Sue Fraser, 208-378-5103/Terry K. Ford, Jr., Contracting Officer E-MAIL: Click here to contact the contracting officer via e-mail., sfraser@pn.usbr.gov. This is a combined synopsis/solicitation. Draft specifications were previously sent out for review and found to be non-restrictive. The Grand Coulee Power Office, Grand Coulee, Washington, has a requirement for a debris boom and boat restraining barrier. SECTION C SPECIFICATIONS: 1.1 SUBMITTAL: To insure that all design-load conditions and other criteria are met, four copies of the following shall be submitted with the proposal. A. Plans and sectional drawings of sufficient scale and clarity to show the following items; floating unit, deal load and design load freeboard, connections; B. All drawings shall be accurately drawn and completely dimensioned. Drawings shall indicate the relevant sizes of all structural members, type of material, finish, thickness, gauge, and other pertinent information for complete evaluation of the system. C. Preliminary engineering calculations showing compliance with design load conditions. Calculation need not be certified by an engineer registered in Washington. D. Descriptions/system information for compatible land and water-based anchoring systems. Note: Contractor shall not be responsible for fabrication or installation of the anchoring system. 1.2 QUALITY ASSURANCE: A. Workmanship -- the barrier system shall be completely prefabricated by the manufacturer and delivered ready for field assembly and installation. B. Warranty -- 1. Floating barrier guarantee: The Contractor shall warrant to the Government this aquatic installation to be free from defects in material and workmanship under normal use and service. At any time, within one year from the date of final acceptance, Contractor will furnish and install, without cost to the Government, any part, assembly, or portion thereof which examination shall disclose to be defective. 2. The Contractor shall also guarantee, in writing prior to acceptance, buoyance for a period of one year from final acceptance, and to replace without cost to the Government any flotation which fails to maintain required buoyancy and uniform freeboard. 1.3 APPLICABLE STANDARDS: A. Uniform Building Code; B. American Institute of Steel Construction "Specifications for the Design, Fabrication, and Erection of Steel for Buildings." "Code for Standards Practices for Steel Buildings and Bridges." C. American Welding Society "Standard Code for Arc and Gas Welding in Building Construction." D. American Society for Testing Materials. 1.4 DESIGN LOADS AND CONDITIONS: A. Loads: 1. Vertical deal load shall consist of the weight of all of the components of each unit. 2. Vertical live load shall be a uniform load of 20 pounds per square foot, applied to the full surface area of each unit. 3. Horizontal loading shall be 150 pounds per lineal foot of barrier. 4. Concentrated live loading load of 400 pounds applied over a 6"x6" area anywhere one each unit. B. Loading conditions: 1. Flotation -- Design for: dead load (see 1.5.A.1); dead load (see 1.5.A.1) plus vertical dock live load (see 1.5.A.2); and dead load (1.5.A.1) plus concentrated load (see 1.5.A.4). Also refer to freeboard requirements in Section 1.6. S. Connections shall be designed for the most critical loading combinations of the components connected. 1.5 PERFORMANCE REQUIREMENTS: Freeboard (A) Dead load only (see 1.4); (1) 70% minimum to top of unit; (B) Dead (see 1.4) load plus vertical dock live load (see 1.4); (1) 25% minimum to top of unit; (C) Dead (see 1.4) load plus concentrated live loads (see 1.4); (1) 10% minimum to top of unit. 1.6 Materials: Flotation units shall be of fire-resistant construction. They shall consist of closed-shell polystyrene, encased completely in linear medium density polystyrene. The polystyrene shall meet ASTM C-578, and shall have a minimum density, in place, of 0.9 pound per cubic foot and a maximum density of 1.2 pounds per cubic foot. Water absorption shall not exceed three percent by volume as tested by ASTM C-272. The polystyrene shall be unable to support combustion without an external heat source. A. The polyethylene encasement shall be rotation molded, have aminimum thickness of 0.187 inch, minimum density of 0.95 grams/cc as determined by ASTM D1505-68, and be manufactured in such a way as to incorporate antioxidants and be resistant to UV radiation and petroleum products for at least 10 years. Flotation units shall be designed to maintain their buoyancy and freeboard even if structurally damaged. One unit shall not deflect without adjacent deflecting. Vertical slip between units shall not exceed 1 inch when deflecting. Each unit shall be cylinder shaped with longitudinal ribbing and conform to the following dimensions: Diameter 14' 11-7/8" O.D. minimum, 15'- 1/8" O.D.; Length 10'0" minimum, 11'2" maximum; Weight 120 lbs minimum, 130 lbs maximum. Ballast: Minimum of C 4 x 5.4 x (length of unit). Channel secured to bottom interior of each unit. Connection: A. Connections shall be so designed that units may be disconnected and moved. B. Connections shall utilize galvanized steel connection plates, with galvanized steel clevis-type connectors and high strength galvanized bolts, or all stainless steel components of the same size and dimension. C. Steel shall conform to either ASTM A-36 or ASTM 466 and shall be hot dipped galvanized with a minimum of two ounces of zinc per square foot of surface after fabrication as per ASTM A-525, A-123, or A-153 as applicable. D. Steel bolts and fasteners shall be ASTM A-325 American standard regular with hexagonal heads and nuts and shall be hot-dipped galvanized in accordance with ASTM A-153, or stainless steel type 304. E. All damage to the galvanized coating of materials, such as that caused from drilling or cutting shall be repaired. Clean damaged surface of galvanized metals and touch-up with two coats of zinc rich paint conforming to ASTM A-780. 1.7 COLOR: traffic orange or international orange. 1.8 TESTING: Performance -- A typical unit will be tested on-site for compliance with the performance requirements of the specifications by the Government, and will be allowed to float in the water for at least 24 hours prior to final acceptance by the government. 2.1 INFORMATION TO ACCOMPANY PROPOSAL: The bidder shall furnish with the proposal four sets of drawings showing the dimensions and materials used in the fabrication of the item, except where this information is presented in the manufacturer's catalog, in which case four copies of the catalog will accompany the proposal. Award will be made all or none to the proposal that meets the minimum specifications and is the lowest price.
