The Florida Department of Transportation Structures Design Office has officially released the July 2006 Structures Manual including the Structures Design Guidelines, Structures Detailing Manual, and Structures Standard Drawings. Copies of the Structures Manual can be downloaded from the Structures Office website at www.fdot.gov/structures.

The Structures Manual is a web based (html) document and includes hyperlinks, navigation tools, indexes, and advanced search capabilities. PDF's for the Design Guidelines and Detailing Manual are included for printing purposes. Standard Drawings and Drawing Examples are available in both MicroStation format (dgn files) and PDF format.

The Structures Manual will be updated twice a year (January and July) and serves as the single source for FDOT design criteria for structural designs prepared by the Department and consultant designers. All users of the Manual are encouraged to submit suggestions to improve and further develop the contents thereby providing maximum assistance to the structural engineering community. Submit any suggestions to Andre Pavlov, Florida Department of Transportation, 605 Suwannee Street, MS 33, Tallahassee, Florida32399-0450, or e-mailed to charles.boyd@dot.state.fl.us.

The design criteria shall be incorporated on all future projects and on those projects currently being developed (i.e., when design and detailing has not already reached final stages). Where incorporation is not feasible, a request for a variance shall be submitted. For specific questions about the Manual, or its application to a particular project, contact the appropriate District Structures Design Office.
