VILLAGE OF KEY BISCAYNE UNDERGROUNDING OF UTILITIES — MASTER PLAN    Because of the requirement for FPL to harden their infrastructure, design and construction of this undergrounding program should begin as soon as practical Pre-Construction Services/Bidding/Award of Phase 1 is to begin in the first quarter of the year to allow adequate time for pre-construction activities and GMP development needed to prepare for an early June construction start. This allows “heavy” construction activities to happen around the school during the summer months. Community outreach is a continuous process that spans across design and construction Construction Phase Schedule Considerations 110  In general, construction activities around the K-8 school should be coordinated to occur during the summer in any one phase  “Heavy” construction activities, such as underground infrastructure work and conduit installation, are desired to be constructed in the summer months when traffic volumes are lowest  Year-round construction activities are considered for the undergrounding program  Water main, stormwater, and conduit installation activities may occur simultaneously in any phase area.  To minimize community/traffic impacts, “heavy” construction impacts will not be allowed to occur in adjacent phases at the same time  Cable and equipment installation activities may overlap the duration of backbone conduit installation within a phase  To achieve schedule compression, portions of phases that can be overlapped should be to the greatest extent practical while minimizing traffic and resident impacts  Feeder switch over to the underground system should be coordinated to occur in the cooler months when electrical demand is low, which reduces the complexity of the process and associated costs  Conversion of individual electric and communications services will follow the energization of the new underground system  Overhead wire and pole removal cannot begin until all services are converted to the new underground system  Roadway, sidewalk, and landscape improvements may occur during the final restoration stage of each phase Schedule Durations The durations of significant activities that occur within each project phase were developed based on information gathered from a variety of sources. Design durations are largely based on Kimley-Horn’s experience with similar projects and through schedule discussions with FPL, AT&T, and Comcast. Construction activity durations were based on relevant projects currently underway or already completed. These were compared to the activities proposed in this master plan as part of the opinion of cost development, which yielded significant activity durations and were then incorporated into the overall schedule. Appropriate schedule contingencies were also applied to account for normal weather impacts, potential geological challenges, and unforeseen conditions.
