The Lake County Administration Center is a complex consisting of two buildings and a single-story, 1,600 sq. ft. atrium connecting the two buildings with a total of approximately 102,000 sq. ft. and budget of $25 million. The existing 5-story Nolan Building received moderate renovations focusing primarily on finishes, building systems, and updates to meet building codes. The new Administration Building is five-stories with each floor totaling approximately 11,000 sq. ft. New central mechanical and electrical rooms are located in the basement level. Tec’s services included the mechanical, electrical and plumbing engineering and lighting design for both the renovation of the Nolan Building and construction of the new Administration Building.
