Peter Kolf, P.E., S.E.

Principal Structural Engineer


  • Structural Engineering + Evaluation


Mr. Kolf has extensive industry experience and is active in a wide range of projects involving structural evaluation, strengthening, rehabilitation, troubleshooting of construction-related problems, and durability enhancement. Typical projects have involved evaluation of the extent and causation of structural distress or deterioration, as well as development and implementation of repairs. These projects have incorporated industrial, commercial, and residential structures; parking garages; water treatment structures; cokers; bridges; piers; tunnels; stadiums; plaza decks; and building facades.

Mr. Kolf’s structural analysis and design projects include the repair of a distressed 100-meter high industrial tower through a unique application of post-tensioning, analysis of a failed transfer slab that forced the evacuation of a 15-story condominium building, and repair of post-tensioned concrete parking structures. He has investigated structural failures including bridge collapses and the collapse of a 425-ft high communications antenna.

Peter’s extensive and diverse experience provides value to clients by facilitating creative solutions to each unique project.
