Palmer provided professional services that included a fracture critical inspection, in-depth inspection of the floor system, and production of repair plans for the historic structure. Subsequent to the field inspections and reporting, Palmer prepared rehabilitation plans to address deficiencies found including repairs to the steel grid deck, deteriorated and/or fatigue-damaged steel members, and deteriorated and/or damaged connection details.
