I-4 Ultimate Corridor Improvements

As part of our Statewide Public-Private Partnership (P3) and Engineering Support Services contract with the Florida Department of Transportation (FDOT) Central Office, RS&H is providing owner’s representative services to District 5 for the $2.3 billion widening of I-4. This project includes the complete reconstruction of I-4, construction of 138 new bridges, upgrades to 19 urban interchanges, and new ITS systems within the FDOT right-of-way. Also included are 21 miles of new tolled express lanes, two eastbound and two westbound.

The I-4 widening was initially planned as six separate design-build contracts and each section’s design consultant produced plans suitable for defining right-of-way and permitting. RS&H was tasked with combining the various contracts into one design-build-finance-operate-maintain contract. RS&H produced a value engineering study to identify and develop innovative alternatives to reduce project cost without sacrificing the overall level of service and project intent. RS&H also developed a detailed cost estimate for the combined project and cost evaluations of each alternative under review. As part of this assignment, the team completed geometric analysis of the whole corridor and updated and analyzed the traffic model. RS&H is providing FDOT a broad spectrum of services under this assignment, including value engineering, procurement, traffic modeling, evaluation of alternatives and analysis, public involvement, cost estimating, project scheduling, permitting, and general engineering support through construction.
