SR A1A Drainage Improvements

RS&H partnered with FDOT on the A1A project which included replacing five bridges in Jacksonville Beach and Neptune Beach in addition to widening/improving the outfall channel serving these communities. The channel was lined with sheet pile which was installed using a non-vibratory press-in method. Other activities included roadway reconstruction, drainage improvements, highway signing, guardrail, box culvert repairs, flatwork, sheet pile, sanitary sewer, water main relocations, and rigid inclusion. 

Each of the five bridges were reconstructed and provided vital access to the elementary, middle, and high schools. The original construction sequencing had these bridges built during school hours and significantly impacting the flow of traffic. Although the contract did provide detours for closing these bridges our CEI team discussed potential scheduling modifications and developed a plan to combine multiple phases of the project shifting this work to the summer months. This combined phasing helped advance the Contractor’s overall schedule and simultaneously eliminated the majority of the impacts to the schools. Beyond the contract allotments for weather only 21 days were added to the contract representing a two-percent increase in time. RS&H monitored our costs closely, adjusting staffing levels to mirror the Contractor’s efforts, ensuring the original CEI contract fees were not exceeded.
