About the instructor
Michael Craig, PE is Senior Vice President and Southeast Director at Strinteg Corporation, leading bridge inspection and structural engineering across eight states and Puerto Rico. In 27+ years he has inspected over 4,000 structures and completed 3,000+ load ratings and 160+ load tests. He has managed repair and preservation design for complex bridges, including cable-stayed bridges. He holds PE licenses in twelve states, DC and Puerto Rico, SPRAT Level 1, and FAA Part 107 credentials.
Virginia's bridge program is governed by VDOT's Structure and Bridge Division instructional memoranda, which are among the most current in the Southeast. VDOT reduces inspection intervals at a condition rating of 4, requires a new load rating whenever a General Condition Rating falls to 4 or below, uses condition factors in LRFR, and requires central office notification when a rating cannot be finished in 3 months. This one-hour course covers those rules plus VDOT's jointless design policy and repair practice.
