Inspect 180–220 bridges per year for MnDOT District 1 and six county clients, covering steel girder, truss, prestressed concrete, culvert, and timber structures. Lead fracture-critical member inspections on 14 steel truss and two-girder spans, including hands-on checks of pin-and-hanger assemblies and gusset plates. Operate under-bridge snooper trucks and coordinate traffic control with MnDOT crews, closing 95% of lane-closure windows on schedule. Record element-level ratings and photo documentation in BrM (AASHTOWare), cutting report turnaround from 12 to 6 working days. Flagged critical section loss on a 1962 deck truss bearing seat, prompting an emergency load posting and a $1.4M rehab let within 9 months. Perform ultrasonic thickness gauging, dye-penetrant testing, and concrete sounding/chain-drag surveys; supervise two junior technicians in the field. Train 7 new hires on NBIS procedures, fall protection, and confined-space entry for box-girder interiors.

Completed routine 24-month inspections on 310 county-owned bridges and large culverts, entering NBI and element data on time every cycle. Measured scour at 40+ waterway crossings after spring floods and recommended riprap and countermeasure repairs adopted in the 5-year plan. Built a photo-indexed defect library that helped engineers prioritize $3.2M in deck overlay and joint replacement work. Assisted with load-rating field verification and posted-bridge sign audits across 2,100 miles of county roads.

Supported district bridge inspectors on deck surveys, bearing measurements, and clearance checks.
