I 1 The girders shall be braced in accordance with Sections 6-02.3(17)F4 and 6- 2 02.3(17)F5. When temporary strands in the top flange are used, they shall be cut 3 after the girders are braced and before the girder deflections are equalized and 4 intermediate diaphragms are cast. 5 6 Instead of the oak block wedges shown in the Plans, the Contractor may use Douglas fir 7 blocks if the grain is vertical. The height of oak block wedges at the girder centerline 8 shall not exceed the width. 1119 10 The Contractor shall fill all block-out holes with a mortar or grout acceptable to the 11 Engineer. 12111 13 For prestressed concrete slab girders, the Contractor shall set stop plates and dowel 14 bars at the top of pier walls with either epoxy grout conforming to Section 9-26.3 or type 15 IV epoxy bonding agent conforming to Section 9-26.1. 16 17 6-02.3(25)0 Deck Bulb Tee Girder Flange Connection 18 This section, including title, is revised to read: 19 20 Girder to Girder Connections 21 When differential camber between adjacent girders in a span exceeds the tolerance in 22 Section 6-02.3(25)1, the Contractor shall submit a method of equalizing deflections as a 23 Type 1 Working Drawing. Any temporary strands in the top flange shall be cut in 24 accordance with Section 6-02.3(25)N prior to equalizing girder deflections. 251 26 Prestressed concrete wide flange deck, deck bulb tee and slab girders with grouted 27 shear keys shall be constructed in the following sequence: 28 29 1. Deflections shall be equalized in accordance with the Contractor's equalization 30 plan. 31 32 2. Intermediate diaphragms shall be placed and weld ties shall be welded. 33 Welding ground shall be attached directly to the steel plates being welded 34 when welding the weld-ties. 35 36 3. The keyways shown in the Plans to receive grout shall be filled flush with the 37 surrounding surfaces using a grout conforming to Section 9-20.3(2). 38 39 4. Equalization equipment shall not be removed and other construction 40 equipment shall not be placed on the structure until intermediate diaphragms 41 and keyway grout have attained a minimum compressive strength of 2,500 psi. 42 43 Prestressed concrete wide flange deck, deck bulb tee and slab girders without grouted 44 shear keys and prestressed concrete wide flange thin deck girders shall be constructed 45 in the following sequence: 46 47 1. Deflections shall be equalized in accordance with the Contractor's equalization 48 plan. 49 50 2. Intermediate diaphragms shall be placed and any weld ties shall be welded. 51 Welding ground shall be attached directly to the steel plates being welded 52 when welding the weld-ties.
