March 6, 2008 - ADOT LRFD Policy Memoranda Developed by NCS Now Available for Download!
As part of our On-Call Geotechnical Services contract with the Arizona Department of Transportation, NCS was tasked with reviewing and implementing the AASHTO Load and Resistance Factor Design (LRFD) Bridge Design Specifications as it pertains to geotechnical engineering. NCS’ scope of work included the comparison of new methods prescribed in the LRFD specifications with the current state of the practice, and the preparation of policy memoranda that would form the baseline of the new standard of practice for geotechnical engineering in Arizona. Three (3) of these memoranda were issued in February of 2008 and are discussed in more on our ADOT LRFD Policy Memoranda page.
