CITY OF SANTA ANA SPECIFICATIONS PROJECT NO.: XX-XXXX PROJECT TITLE 188 All butterfly valves shall be tested for leakage at the same time that the connecting pipelines are hydrostatically tested. In addition, all butterfly valves 12-inches in diameter and larger shall be field tested for leakage. Valves may be tested in a horizontal position. All valves shall be tested bi - directionally after the actuator/operator is installed and the adjustment stops are set. Each side of the valve is to be tested for a duration of at least five (5) minutes at the pressure rating of the valve with zero loss or leakage. The field pressure test shall be witnessed by the City’s representative. Final field tests shall be performed within 75 miles o f the project site. A minimum of 72 hours (or three working days) advance notice to the City for testing is required. 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. Section 302-6.4.4 entitled "Final Finishing" of the Standard Specifications shall be modified as follows: Delete all reference to wetted burlap. Final finish of the surface shall be textured by stiff broom process that will produce scoring perpendicular to the centerline of the street, performed at a time and in a manner to produce a hardened surface have a coefficient of friction of not less than 0.38 as determined by California Test 342. Curing to be applied immediately following broom process. 505 E Central Ave #B11/6/2024
