FEATURED CASE STUDY

Duval County Courthouse

Civil & Roadway Design | Jacksonville, FL

CSI served as a key design-build team member for the 800,000 SF Duval County Courthouse in downtown Jacksonville, Florida — one of the most complex civic infrastructure projects in the region.

CSI's scope included civil site design, roadway design, and stormwater drainage, highlighted by the full realignment of Monroe Street to accommodate the courthouse entrance. Utility design encompassed potable water distribution and sanitary sewer collection systems, with permitting coordinated across multiple agencies including the City of Jacksonville, Jacksonville Electric Authority (JEA), and the Environmental Protection Agency (EPA).

A core engineering challenge was maximizing the use of existing in-place structures to minimize costs — requiring extensive coordination across all design disciplines throughout the project lifecycle.
