To keep pace with the ever-expanding global trade, the Intracoastal Waterway was identified for planned improvements, including dredging. The proposed improvements would have impacted existing facilities and infrastructure, including water and force mains, below the waterway sea floor.
To remedy this issue, CHA provided design-build services for the design, permitting, and construction inspection of a water main and force main traversing the Intracoastal Waterway in the area of East Las Olas Boulevard. Horizontal directional drilling was used to install 1,220 feet of 16-inch and 20-inch water main before connecting the proposed and existing water mains. Other work related to this installation included cutting and capping the existing 16-inch water main on the north side of Las Olas Blvd Bridge at both sides of the Intracoastal Waterway and connecting all proposed piping to the existing piping on-shore utilizing 16-inch PVC pressure pipe meeting AWWA C905 standard.
