FDOT Standard Plans Index 521-825: 42" Concrete Pedestrian/Bicycle Railing
Short answer
Index 521-825 is the FDOT Standard Plan for 42" Concrete Pedestrian/Bicycle 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 Index 825 cannot be used as a traffic railing. A crashworthy traffic railing is required between this railing and adjacent traffic lane. Use this standard in conjunction with Indexes 521 - 427 or 521 - 42 8 .
To preserve the structural integrity, no more than two 2" diameter conduits and associated Embedded Junction Boxes, as shown on Standard Plan s Index 630 - 0 10, may be installed within this railing. This railing is intended for locations where theft of the aluminum components on Index 521 - 820 is a warranted concern as determined by the District Maintenance Office.
General Notes
General Notes Sheet, specify the concrete class in accordance with the superstructure or retaining wall environment classification. See SDG 1.4. In the Concrete Surface Finish Coating Note on the General Notes, specify any special textured surface requirements and/or colors for the Class 5 Finish Coating (if used) .
See Standard Plan s Index 5 34 - 200 for examples of textured surface options. Use only those with depth or amplitude less than or equal to ½” to maintain 2” cover for reinforcement. Show and label the 42" Concrete Pedestrian/Bicycle 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 as required.
All concrete required to construct the railing and Bars 3R and 4S are included in the Estimated Concrete Railing Quantities. Do not include railing concrete in the estimated concrete quantities, or Bars 3R and 4S in the reinforcing bar lists and estimated reinforcing steel quantities for supporting bridge decks, approach slabs or retaining walls. Standard Plan s Instructions Topic No.
