Ii 2 When spacing between bars is 1 foot or more, they shall be tied at all intersections. When spacing is less than 1 foot, every other intersection shall be tied. If the Plans require 3 bundled bars, they shall be tied together with wires at least every 6 feet. All epoxy-coated 4 bars in the top mat of the bridge deck shall be tied at all intersections, however they may I 5 be tied at alternate intersections when spacing is less than 1 foot in each direction and 6 they are supported by continuous supports meeting all other requirements of supports for 7 epoxy-coated bars. Other epoxy-coated bars shall also be tied at all intersections, but I 8 shall be tied at alternate intersections when spacing is less than 1 foot in each direction. 9 Wire used for tying epoxy-coated reinforcing steel shall be plastic coated. Tack welding 10 is not permitted on reinforcing steel. Iii 12 Abrupt bends in the steel are permitted only when one steel member bends around 13 another. Vertical stirrups shall pass around main reinforcement or be firmly attached to it. 14 I 15 For slip-formed concrete, the reinforcing steel bars shall be tied at all intersections and 16 cross braced to keep the cage from moving during concrete placement. Cross bracing 17 shall be with additional reinforcing steel. Cross bracing shall be placed both longitudinally I 18 and transversely. 19 20 After reinforcing steel bars are placed in a traffic or pedestrian barrier and prior to slip- 21 form concrete placement, the Contractor shall check clearances and reinforcing steel bar I 22 placement. This check shall be accomplished by using a template or by operating the slip- 23 form machine over the entire length of the traffic or pedestrian barrier. All clearance and 24 reinforcing steel bar placement deficiencies shall be corrected by the Contractor before I 25 slip-form concrete placement. 26 27 Precast concrete supports (or other accepted devices) shall be used to maintain the 128 concrete coverage required by the Plans. The precast concrete supports shall: 29 30 1. Have a bearing surface measuring not greater than 2 inches in either dimension, and I 31 32 2. Have a compressive strength equal to or greater than that of the concrete in which 33 they are embedded. 34 I 35 In slabs, each precast concrete support shall have either: (1) a grooved top that will hold 36 the reinforcing bar in place, or (2) an embedded wire that protrudes and is tied to the 37 reinforcing steel. If this wire is used around epoxy-coated bars, it shall be coated with I 38 39 plastic. 40 Precast concrete supports may be accepted based on a Manufacturer's Certificate of I 41 Compliance. 42 43 In lieu of precast concrete supports, the Contractor may use metal or all-plastic supports 44 to hold uncoated bars. Any surface of a metal support that will not be covered by at least 1 45 1/2 inch of concrete shall be one of the following: 46 47 1. Hot-dip galvanized after fabrication in keeping with AASHTO M232 Class D; I 48 49 2. Coated with plastic firmly bonded to the metal. This plastic shall be at least 3/32 50 inch thick where it touches the form and shall not react chemically with the I51 concrete when tested in the State Materials Laboratory. The plastic shall not ICITY OF EVERETT AMENDMENTS PACIFIC AVENUE TO INTERURBAN TRAIL BICYCLE SAFETY PROJECT 8/12/2019 ISTATE FUND#HLP PB17(014); COE#PW3688 Page AM-39
