Gareth Rees



Gareth Rees’s experience includes movable bridges, heavy industrial, electrical and electric utility generation, transmission, and distribution. Mr. Rees has conducted switchgear development and application, power generation, distribution analysis and design, control system design (including PLCs and distributed analog and digital control systems), motor, motor control and motor drive technologies and their heavy machinery applications, communications engineering, contract management, construction supervision, commissioning, and start-up. Mr. Rees’s movable bridge experience spans more than thirty years and includes hundreds of movable bridge inspections ranging from cursory to in-depth inspections, failure analysis, and troubleshooting. His movable bridge engineering and design expertise includes rehabilitation of existing bridges and design of new bridge electrical power and control systems. Mr. Rees is familiar with the application of the Canadian Highway Bridge Design Code, AASHTO LRFD Movable Highway Bridge Design Specifications, and AASHTO Movable Bridge Inspection, Evaluation, and Maintenance Manual. His experience enables him to bring the electrical systems of a movable bridge project from the conceptual stage through the completion of construction.
