1 AASHTO LOAD AND RESISTANCE FACTOR LRFD BRIDGE DESIGN SPECIFICATIONS
2 LRFD IMPLEMENTATION BY OHIO DEPARTMENT OF TRANSPORTATION
3 1. All new bridges on which States initiate preliminary engineering after October 1, 2007, shall be designed by the LRFD Specifications.
4 2. All new culverts, retaining walls, and other standard structures on which States initiate preliminary engineering after October 1, 2010, shall be designed by LRFD Specifications, with the assumption that the specifications and software for these structures are "mature" at this time.
5 3. States unable to meet these dates will provide justification and a schedule for completing the transition to LRFD.
6 4. For modifications to existing structures, States would have the option of using LRFD Specifications or the specifications which were used for the original design.

9 1. Major Projects as defined by the PDP Projects starting Step 6 after July 20, 2007 shall have the structures designed using the LRFD Bridge Specifications.
10 2. Minor Projects as defined by the PDP Projects starting Step 3 after July 20, 2007 shall have the structures designed using the LRFD Bridge Specifications.
11 3. Minimal Projects as defined by the PDP Projects starting Step 1 after July 20, 2007 shall have the structures designed using the LRFD Bridge Specifications.
12
13 Local projects using the Federal Aid and the ODOT PDP process shall have the structures designed using the LRFD Bridge Specifications after October 1, 2007.
14 This commitment does not apply to the rehabilitation of existing structures. Until further notice, the design for rehabilitation of existing structures should be in accordance with the AASHTO Standard Specifications for Highway Bridges, 17th Edition, and the ODOT Bridge Design Manual.
15 This commitment does not apply to the rehabilitation of existing structures. Until further notice, the design for rehabilitation of existing structures should be in accordance with the AASHTO Standard Specifications for Highway Bridges, 17th Edition, and the ODOT Bridge Design Manual.
16 The Department s Consultants Committee has decided that completion of specific training courses will not be a prequalification requirement. However, beginning immediately all website This commitment does not apply to the rehabilitation of existing structures. Until further notice, the design for rehabilitation of existing structures should be in accordance with the AASHTO Standard Specifications for Highway Bridges, 17th Edition, and the ODOT Bridge Design Manual. postings for new consultant contracts that include bridge design will include a requirement to address the training and experience (in LRFD) of the proposed staff. Additionally, firms with current contracts that will require LRFD as a result of the project development schedule will be required to demonstrate an adequate combination of training and experience in the new design methods.
