NIGP 92594: Tunnels and Subways/Engineering

NIGP 92594 Tunnels and Subways/Engineering, an Item code, encompasses consulting services for design, engineering oversight, cost estimation, and construction administration on surface and transit infrastructure projects—though the recent solicitations show this code captures broader transportation and public works engineering work beyond traditional tunnels and subways. State and local governments procure design-build support, independent cost estimating for alternative delivery projects, construction engineering and inspection for intelligent transportation systems, general engineering consulting for express lane and roadway improvements, and professional engineering services for wastewater treatment facilities and pedestrian infrastructure under this code. The issuing bodies include state departments of transportation (Georgia DOT leading recent activity), county governments (Madison County, DeKalb County, Chatham County), and municipalities (City of Griffin, City of Social Circle, City of Madison, City of Union City, City of Nicholls), with Georgia DOT appearing repeatedly for multi-phase transportation projects using alternative delivery methods.
