City of Sunny Isles Beach RFQ No. 18-08-01 | Consulting Engineering Services for Golden Shores Utility Undergrounding and Roadway Improvements (CCNA) <br />In conjunction with inventory and data collection task, the design survey will begin. The surveying task will show the platted right-of-way lines, platted easements, and adjacent adjoining recorded plats within the designated corridor. The survey map will also depict the above-ground improvements within the project limits, with horizontal locations and vertical elevations being provided for required items such as edge-of-pavement, sidewalks, driveways, access points, and visible above-ground utilities. Additionally, the locations of the private electric service connections will be surveyed in order to prepare for relocating the services from the back-yard to the front yards. Since easements will be necessary in private property to accommodate utility equipment, above ground improvements within 10’ of the right-of-way as well as projected path from the electrical service meter to the right-of-way will also be captured by the survey crew. A tree survey will be performed in conjunction with the landscape architecture department to properly identify species, size and condition of trees within the project limits. Survey data will be referenced vertically to North American Vertical Datum 1988 (NAVD88) and horizontally to Florida State Plane Coordinates, North American Datum 83/90 (NAD 83/90). The survey will be prepared in accordance with the standards as set forth by Chapter 5J-17 of the Florida Administrative Code, pursuant to Florida Statues Chapter 472.027. <br />Once all the information has been assembled through the inventory and data collection phase, preliminary design begins. Another site visit to the neighborhood to confirm utility and survey information, as well as familiarizing the project team with design elements will occur. These site assessments are critical during this analysis phase as well as throughout the life of the design project. <br />PRELIMINARY DESIGN <br />The preparation of design drawings can begin once the inventory and data collection phase has been completed. During the preliminary design, regular meetings with the UAO's will ensure coordination of their individual designs from schematic to conceptual layouts. These regular meetings will continue while developing construction plans with final design layouts that work for the City and neighborhood as well as for each provider. These plans are utilized to finalize the coordination of locations of utilities and begin the discussion and review of required easements. The plans are also utilized to begin the pre-application process with the review and permitting agencies as well as with any relevant stakeholders. This process involves multiple <br />meetings with the City staff to ensure the project is moving in the intended direction and on schedule. <br />The following is a general description of additional tasks separated by discipline that are part of this design process. <br />Civil/Roadway/Drainage Engineering <br />The improvements include gathering all existing utilities as mentioned above and converting overhead utilities to underground trenches. Where possible, placing the combined utility trenches in, or as close to the swale areas as possible will minimize pavement/concrete reconstruction when performing maintenance in the future and allow for better maintenance of traffic during construction through the neighborhood. The installation of the utilities underground will result in reconstruction/restoration to pavement, concrete sidewalks/curbs, pavement markings and signage, and landscape allowing for an opportunity to upgrade and enhance the neighborhood. Diligent coordination during design to place multiple utilities in the same trench will minimize the overall impacts. The CGA team will analyze the option of directional drilling for some utilities in specific areas in order to further reduce impacts, where possible. Once the contractor has installed the conduit and pads, the utility contractors will need to pull the wires and set transformers. During this time, CGA’s construction manager will ensure the contractor is coordinating with the UAO’s and keep the City updated on the status in order to keep the residents informed of disturbances. <br />The CGA team will review the existing drainage system and familiarize ourselves with the pump station upgrades in order to ensure any necessary system upgrades to the catch basins or collection system are included in the project. Roadways and swales that are being disturbed by trench installation will be reconstructed with proper slopes to aid in better drainage flow while taking into consideration harmonization with the existing driveways. <br />10
