111 <br /> 1 19. Position of post tensioning ducts in spliced prestressed concrete girders: ± 1/4 <br /> 2 inch. <br /> 3 <br /> 4 20. Deviation from a smooth curve for post-tensioning ducts at closures based on <br /> 5 the sum total of duct placement and alignment tolerances: ± % inch. <br /> 6 <br /> 7 6-02.3(25)J Horizontal Alignment <br /> 8 This section is revised to read: <br /> 9 <br /> 10 The Contractor shall check and record the horizontal alignment of the top and bottom <br /> 11 flanges of each girder at the following times: <br /> 12 <br /> 13 1. Initial — Upon removal of the girder from the casting bed. <br /> 14 <br /> 15 2. Shipment—Within 7 days prior to shipment. <br /> 16 <br /> 17 3. Erection —After girder erection and cutting temporary top strands but prior to <br /> 18 any equalization, placement of weld ties or placement of diaphragms. <br /> 19 <br /> 20 Each check shall be made by measuring the distance between each flange and a chord <br /> 21 that extends the full length of the girder. The Contractor shall perform and record each <br /> 22 check at a time when the alignment of the girder is not influenced by temporary <br /> 23 differences in surface temperature. Records for the initial check (Item 1 above) shall be <br /> 24 included in the Contractor's prestressed concrete certificate of compliance. Records for <br /> 25 all other checks shall be submitted as a Type 1 Working Drawing. <br /> 26 <br /> 27 Immediately after the girder is removed from the casting bed, neither flange shall be <br /> 28 offset more than % inch for each 10 feet of girder length. During storage and prior to <br /> 29 shipping, the offset (with girder ends plumb and upright and with no external force) shall <br /> 30 not exceed % inch per 10 feet of girder length. Any girder within this tolerance may be <br /> 31 shipped, but shall be corrected at the job site to the %s inch maximum offset per 10 feet <br /> 32 of girder length before concrete is placed into the diaphragms. <br /> 33 <br /> 34 The Engineer may permit the use of external force to correct girder alignment at the <br /> 35 plant or job site if the Contractor provides stress calculations and a proposed procedure. <br /> 36 If external force is permitted, it shall not be released until after the bridge deck has been <br /> 37 placed and cured 10 days. <br /> 38 <br /> 39 The maximum deviation of the side of a prestressed concrete slab girder, or the edge of <br /> 40 the top flange of a wide flange deck, wide flange thin deck, deck bulb tee, double tee or <br /> 41 ribbed girder, measured from a chord that extends end to end of the member, shall be ± <br /> 111 <br /> 42 % inch per 10 feet of member length, but not greater than 1/2 inch total. <br /> 43 <br /> 44 6-02.3(25)K Girder Deflection <br /> 45 This section, including title, is revised to read: <br /> 46 <br /> 47 6-02.3(25)K Vertical Deflection <br /> 48 The Contractor shall check and record the vertical deflection (camber) of each girder at <br /> 49 the following times: <br /> 50 <br /> 51 1.
