The project won the American Consulting Engineers Council Grand Award for Special Projects in 1991.

Project manager for construction of a 24-inch diameter, 1,800-foot-long, high-density polyethylene overland siphon. Project included site investigation, ascertaining feasibility, completion of mechanical calculations, specification of pipeline material and fabrication method, development of the bill of material, and execution of the design drawings required by the contractor and government agencies. The siphon was constructed in two weeks, at a remote work site and under extreme conditions. Supplying 20 million gallons per day, the line exceeded the design flow rate, averted a mill shutdown, and prevented the layoff of 600 employees by replenishing the mill's primary watershed. The project was featured in the August 1990 issue of Civil Engineering magazine.

Supervised the operation, testing, and maintenance of a shipboard nuclear propulsion plant, including all primary (nuclear) and secondary mechanical systems and equipment. Qualified by the Naval Sea Systems Command as Engineer Officer of a nuclear-powered ship.
