WGI was the engineer of record for this $32 million Design-Build project for the Florida Department of Transportation District Four. This project increased capacity and improved safety by widening a 2.1-mile section of SR 7, converting it from a five-lane section with center turn lane to a six-lane divided urban arterial section. Other improvements include installation of a new stormwater management and collection system; sanitary sewer (gravity and force mains); two 12” water mains; lateral connections; and all other associated features, such as valves, meters, etc. Right-of-way acquisition for over 40 parcels was required. A Utility Work by Highway Contractor Agreement (UWHCA) between the City of Hollywood and the FDOT paid for the water and sewer improvements.
This was the first Design-Build project in District 4 where the FDOT handed the responsibility for assessment and remediation to the Design-Build contractor/ engineer. WGI’s Contaminated Area Management Plan addressed soil and groundwater that was contaminated by arsenic and petroleum hydrocarbons. Sections of the project corridor had been previously labeled as contaminated, but WGI found uncertainties with some of the previous data and retested areas within the limits of construction. Based on their results, WGI found numerous areas of the project did not require remediation which shortened the overall project schedule and reduced costs significantly.
Permits were secured from Broward County Health Department, Broward County, City of Hollywood, Broward County Environmental Program and Growth Management, South Florida Water Management District (SFWMD), and the Florida Department of Environmental Protection (FDEP).
