FDOT Standard Plans Index 521-820: 27" Concrete Parapet with Pedestrian/Bicycle Bullet Railing
Short answer
Index 521-820 is the FDOT Standard Plan for 27" Concrete Parapet with Pedestrian/Bicycle Bullet Railing, part of Series 521 (Incidental Construction). The sections below are extracted from FDOT's Standard Plans Instructions (SPI) for this index — design criteria, assumptions and limitations, and what your plans must show.
Design Criteria
Design Criteria AASHTO LRFD Bridge Design Specifications ; Structures Design Guidelines ( SDG )
Design Assumptions and Limitations
Design Assumptions and Limitations The standard height railing is the Pedestrian / Bicycle Railing (42" height). The Special Height Bicycle Railing (48" height) should only be used where warranted by AASHTO LRFD C13.9.2. Index 521 - 820 cannot be used as a traffic railing.
A crashworthy traffic railing is required between Index 521 - 820 and adjacent traffic lanes. Use this standard in conjunction with Indexes 515 - 022, 521 - 42 7 , or 521 - 42 8 and 550 - 0 10, 550 - 0 11, 550 - 0 12 or 550 - 0 13 .
General Notes
General Notes Sheet, specify the concrete class in accordance with the superstructure or retaining wall environment classification. See SDG 1.4. Show and label, by name or Index number, the Pedestrian / Bicycle Bullet Railing on the Plan and Elevation, Typical Section, Superstructure, Approach Slab and Finish Grade Elevations Cross Section sheets, Retaining Wall Control Drawings, and other sheets a s required.
Specify the type of railing required, e.g., Pedestrian / Bicycle Bullet Railing or Special Height Bicycle Bullet Railing. Include cross references to Standard Plan s Index 550 - 0 10, 550 - 0 11, 550 - 0 12 , 550 - 0 13 or 515 - 0 22 as appropriate. All concrete required to construct the parapet and Bars 4P and 4S are included in the Estimated Concrete Parapet Quantities.
Do not include parapet concrete in the estimated concrete quantities, or Bars 4P and 4S in the reinforcing bar lists and estimated reinforcing steel quantities for supporting bridge decks, approach slabs or retaining walls.
