Mr. Hearst is an engineer specializing in airport construction and development with over 40 years of experience in various airport and airfield related projects. After 20 years of service in the U.S. Air Force, Mr. Hearst joined Booker Associates as the Construction Manager for the upgrade and expansion of the St. Louis-Lambert International Airport. This $125 million program, which included the complete rebuilding and extension of parallel runways, a new taxiway, an aircraft parking apron extension, and a replacement and upgrade of the interior airfield lighting system, was completed a year ahead of schedule and significantly under budget. In 1982, Mr. Hearst was selected as the President of Booker Construction Managers, a subsidiary of Booker Associates established to manage all Booker Construction Managers, Inc. design/build projects.

In 1984, Mr. Hearst joined Campbell Construction Services as the Principal responsible for all construction activities of the corporation. These included the management of personnel, negotiation of fees and contracts, preparation of all bid documents and supervision of construction projects. The majority of projects completed were in the $5-$10 million range.

In 1989, Mr. Hearst joined Sverdrup Corporation and was responsible for managing airport and airfield related programs at various locations around the United States. Among the projects Mr. Hearst oversaw during his tenure was the construction of the Mid-America Airport in St. Clair County, Illinois. This $480 million project included construction of a 10,000-foot runway, four gate terminal facilities, airport access roads and parking, and associated landside operation and safety facilities.

Due to his unique experience in St. Louis, Parsons, Brinckerhoff, Quade, and Douglas recruited Mr. Hearst in 1998 to assist in the company's efforts to be selected for a major project in the St. Louis-Lambert Expansion Program. Mr. Hearst assembled a joint venture design team that was selected by the City of St. Louis to design the first major project of the airport expansion program. This project included the design of grading and storm water drainage for a two-square mile area with an estimated construction cost of $85 million.

Mr. Hearst's most recent assignment was as President of the Board of Public Service for the City of St. Louis. In this role he was responsible for directing four key divisions: the Design and Construction Division, the Facilities Management Division, the Equipment Service Division, and Soldier's Memorial. His responsibilities in this position included strategic planning, staff management of over 230 employees, development and implementation of a $25 million annual budget, and serving on more than eight public boards and commissions. Projects Mr. Hearst oversaw during his tenure included the $86 million Downtown Justice Center, the $100 million Forest Park Master Plan, and the $2 billion Lambert Expansion Program.
