Robert J. Tosolt



Robert Tosolt has more than twenty-seven years of experience in the movable bridge field, where he has focused on movable bridge operating and support systems. Mr. Tosolt is familiar with both rail and vehicular bridges, where his work experience has covered the spectrum of movable bridge types and vintages. His experience encompasses all types of engineering related to movable bridge operating and support systems, including design of new machinery, load rating of existing machinery, preparation of plans, specifications, estimates (PS&E), bridge machinery safety inspections, and providing emergency call-out services to troubleshoot, identify, and resolve machinery failures and operational malfunctions. Mr. Tosolt also has extensive experience in strain gage drive testing and bridge balancing, and construction support engineering including review for constructability, yellow-line review of shop drawings, review of equipment installation procedures, shop inspection, machinery alignment verification, oversight of system commissioning, and serving as movable bridge project coordinator on multiple projects.
