CITY OF SANTA ANA SPECIFICATIONS PROJECT NO.: XX-XXXX PROJECT TITLE 186 7.13 RESILIENT WEDGE GATE VALVES This work shall consist of furnishing and installing gate valves, including risers with valve boxes, and PCC collars where indicated on the plans. All work shall conform to City of Santa Ana Standard Plan No. 1410. Gate valves shall be of the size and configuration as indicated on the plans and shall be AWWA and UL/FM tested, resilient wedge with operating nuts and non-rising stems, and shall be designed for a minimum working pressure of 150 psi and be tested at 200 psi. Valves shall be bubble-tight at the working pressure. Gate valves shall be Clow, Mueller, Renselear, or approved equivalent. Valves shall have Type 316 stainless steel nuts and bolts and shall be manufactured in accordance with AWWA C509 Standards. Valve linings and coatings shall be made in accordance with AWWA C-550. All valves to fitting connections shall be flanged. Valves for lateral lines shall be bolted directly to main line tee, unless otherwise noted on the plans. Where it is necessary to install a reducer or other type of fitting between the lateral valve and main line, said fitting shall be flanged at both ends. All valve box frame and covers shall require PCC collars and shall be adjusted to finished grade following paving operations. Portland cement concrete pavement for gate collars shall conform to Sections, 400, 200, 201, and 302 of the Standard Specifications and these Special Provisions. PCC used for gate collars construction shall be minimum class 560-A-3250. In addition to these minimum requirements, the concrete shall possess the following characteristics:  Flexural strength at 28 days: 550 p.s.i. min.  Flexural strength at 7 days: 430 p.s.i. min.  Compressive strength at 7 days: 2500 p.s.i. min. All cement to be used or furnished on this Project shall be Type II low alkaline Portland cement conforming to ASTM C150. Prior to the start of construction, the Contractor shall furnish to the Engineer laboratory test data for the particular mix design he will use. The data will include the following: A. A detailed concrete mix design including the type and amount of cement used; complete gradation and source of the aggregate used; the amount of water used; and any proposed admixtures. B. Flexural strength test data for the same batch of concrete used in A above showing the compressive strength of the concrete at 3, 7, and 28 days. 505 E Central Ave #B11/6/2024
