FDOT Standard Plans Index 534-250: Perimeter Wall

Design Criteria

Design Criteria AASHTO LRFD Bridge Design Specifications ; Structures Design Guidelines ( SDG )

Design Assumptions and Limitations

Design Assumptions and Limitations Design Assumptions: Wall heights are a nominal 8 feet above finished grade. Foundations have been designed for loose sand with an uncorrected SPT blow count of N=5 or greater. Clayey soils were investigated and did not control the design.

Precast Option Design Assumptions: • Wall Panels, as designed, are adequate for all wind zones when installed between posts spaced at 20'-0". • Post reinforcing and foundation depths are based on 20'-0" post spacing with a maximum wind exposed wall height of 9'-0". • Auger cast pile foundations were designed in accordance with the Soils and Foundations Handbook , Appendix B.

Masonry Option Design Assumptions: • Walls are designed as a continuous cantilevered wall in accordance with ACI 530 using Strength Design for a maximum wind exposed wall height of 8'-8" with the top of foundation a minimum of 6" below grade. • Foundations are designed in accordance with AASHTO LRFD , Section 15. Design Limitations: See the FDM , 264 for limitations on the applicability of this Index.

Perimeter Walls are not designed for vehicle impact loads. If the walls cannot be placed at the required set back distances or behind traffic railings or guardrail they will not be allowed. Ensure system is constructible with consideration of overhead clearances (i.e.

overhead services, tree canopies, existing overhead structures, etc.) and existing underground services along the entire length of the wall. • If foundations will be installed on a slope, adjust the standard foundation depths based on the Soils and Foundations Handbook .

What your plans must show

Plan Content Requirements for this index — the SPI's checklist for designers.

• • Perimeter Wall Alignment / Location
• • Begin/End Wall Stationing and Offsets
• • Offset definition; usually from Baseline to Front Face of Wall
• • Adjacent overhead or in-ground services
• • Limits of sod or seeding/topsoil application
• • Where removal of or improvements to organic soils are necessary, show the limits of organic soils and the limits of required improvements in the plans along with removal/improvement methods and method of payment. Elevation
• • Bottom of Wall Elevations and Finished Grade Line.
• • Step Locations If the base elevations or wall height requirements change along the length of the project, step bottom and/or top of walls and post/pilaster elevations to maintain the aesthetic qualities while meeting the design criteria requirements. o Drainage Holes (Including type) Index 534-250 Perimeter Wall o Adjacent overhead or in-ground services o Limits of anti-graffiti coating (if required) o Guardrail or delineators on back face of wall Complete the "PERIMETER WALLS DATA TABLE" with notes; include them in the plans.
