DESIGN LOAD RATING SUMMARY TABLES
http://www.dot.state.fl.us/structures/CADD/standards/CurrentStandards/MicrostationDrawings.shtm
Manual revisions are available on the Structures Design Office website at:
CADD Software for the Microstation CADD Cell Summary Tables. Updates to the Summary Tables from Structures
with the Structures Manual (Topic No. 625-020-018). See the "FDOT Structures Bar Menu" included with the FDOT
Load Rating Summary Tables must be completed by the designer and included in the contract plans in accordance
