The purpose of this project was to rehabilitate the Long Beach Road Drawbridge over Reynolds Channel. The rehabilitation included mechanical and electrical retrofits for the bascule machinery as well as a new steel grid deck, deck support girders, bridge bearings, deck joints, and complete bridge painting with environmental protection for lead abatement.
WHAT MADE THIS JOB COMPLEX
What made this project difficult was that both vehicular traffic and marine traffic needed to be maintained at all times. The drawbridge was the main access point to the City of Long Beach so it would be an extremely busy worksite. Maintaining traffic, both on the bridge and water, was essential.
HOW POSILLICO SOLVED IT
The project could not be built as put forth in the original design documents. Posillico proposed an alternate Value Engineering design, which modified the MPT scheme that enabled the closure of one of the two bascules. This enabled the reconstruction of each bascule while still maintaining both vehicular and marine traffic. It also reduced the traffic stages from three down to two which reduced the overall project schedule from 36 months to 24 months We also utilized our internal marine capacity by working mostly from barges to access most of the work which was required below the roadway surface.
