OUR PORTFOLIO

Civil Engineering Portfolio | CSI Project Experience

Since 1989, CSI has delivered successful civil engineering projects across Florida and Georgia. Our portfolio reflects a consistent record of quality, precision, and client partnership — spanning roadway, bridge, structural, and site development work for public and private sector clients.

From complex bridge design and rehabilitation to large-scale transportation infrastructure and civil site development, CSI's project experience speaks for itself.

Lake Butler Trail

Lake Butler Trail – Putnum County, FL

Florida Department of Transportation, District 2

CSI provided design services for the SR 100 Rails to Trails project in Putnam County.  The project included the design of a 291-foot-long pedestrian bridge to be constructed in place of an existing railroad trestle bridge.  The bridge consisted of 3 97-foot spans.  The bridge was a pre-engineered truss.  CSI provided design criteria and substructure design. 

CSI also provided the design of a concrete box culvert replacement to replace the existing structurally deficient pipe culvert. Services included bridge design, trail design, bridge hydraulics, cost estimates, and environmental permitting.

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.
