Bridge Load Ratings & Inspections
Portage County Engineer | Portage County , Ohio
Osborn performed hands-on bridge inspections for the purpose of performing Bridge Load Ratings, including SHV and EV, for a total of 12 structures within Portage County, Ohio. The bridges were inspected in accordance with the most current ODOT Bridge Inspection Manual, and required inspecting all members within arm's-length reach. A combination of ladders and climbing techniques were utilized to access the various bridge members for inspection. A hands-on field inspection was required to obtain sizes of bridge elements due to the absence of existing plan drawings, and also to quantify areas of deterioration. In addition to performing the field inspection work, Osborn performed load ratings for all structures utilizing AASHTOWare BrR and the finite-element software, CANDE as required.
