Site work for a water / sewer project in Port St Lucie, Florida. Conceptual plans call for site work for a water / sewer project.

The City of Port St. Lucie is seeking the professional services of individuals, firms, and legal entities capable of providing Design Services for a 16" Force Main from Becker Road to connect at the Westport Wastewater Treatment Facility. It is the intent of the City to obtain the assistance of an experienced design engineer to both analyze and address the capacity needs of the City by providing engineering services in two phases. In Phase 1, the selected design engineer will analyze the existing conditions including the "Master Plan", subsequent updates, Utility Systems Department GIS ("GIS"), and record drawings to determine whether the additional capacity of the proposed 16" Force Main is indeed enough to address the City's needs as well as the best route for the proposed Force Main. In Phase 2, the selected design engineer will obtain survey and geotechnical information along the chosen route and, based on the gathered information, as well as the results of the technical analysis, will design a Force Main that meets or exceeds the needs of the. BACKGROUND As per the 2005 Port St Lucie Water Delivery and Wastewater Collection Master Plan ("Master Plan") and the subsequent 2012 update, the City will need to address growth by installing additional Force Main capacity from the SE portion of the City toward the Westport Wastewater Treatment Facility ("Westport"). Development in this area is now being routed through a 12" Force Main starting on Becker RD, then increasing to 16" as it travels under the Florida Turnpike, heads north on Darwin BLVD toward "Westport." The analysis included in both the "Master Plan" and its subsequent update anticipates the need for an additional 16" Force Main, generally parallel to the existing one. SIZE AND ROUTE ANALYSIS The selected design engineer shall review and analyze the available information including the existing pipelines, the "Master Plan," the update as well as the planned developments in the collection area to determine whether the proposed size of the conceptual 16" Force Main is enough to meet the City's needs for this Area. The City will provide all information pertaining to upcoming projects as well as any population projections useful to this task. The selected design engineer shall additionally review all available aerial, topographic, property and utility maps within the subject as well as conduct surface reconnaissance field trips as needed to determine an alignment that conforms with the scope. Consideration shall be given to existing road conditions, available right of way and easements for pipeline routes, quantity and size of trees/power poles that may impact alignment, and other factors identified in the field that could be a hindrance or impact to pipeline routing. Using this information as a base, two (2) potential routes shall be evaluated to determine the best apparent solution. The proposed route shall include: o The location of existing major underground infrastructure such as utility piping and stormwater drainage piping as shown in as-built drawings provided by CITY and available from the City of Port St. Lucie utility mapping CAD files. Any conflicts with existing pipe(s), power, cable, or other utilities; and any other construction related issues will be highlighted for discussion. o The location of existing aboveground infrastructure such as buildings, pavement, concrete pads, driveways, signs, bus stops, traffic signals, etc. as provided by Design Engineer's survey. o Identified areas of concern that will be evaluated using subsurface exploration during the site survey work. o Type of construction (open-cut or trenchless techniques). o Maintenance of Traffic concerns. The result of the size and route analysis shall constitute the 30% design submittal. PRELIMINARY DESIGN SERVICES Geotechnical Services o Perform subsurface explorations along the force main route necessary for the characterization of the existing subsurface conditions and development of preliminary design criteria for the proposed force main. For budgeting purposes, it is assumed that geotechnical borings will be required at maximum intervals of 1,500 ft. and to a depth of at least five (5) feet below the pipe invert and the drill pits. For budgeting purposes, all subsurface explorations are assumed to occur within the roadway right-of-way. o Perform SPT borings. o Perform classification tests on selected samplings obtained from the borings. o Visually classify soil samples in general accordance with the United Soil Classification System and prepare Test Boring Records. o Summarize the results of the geotechnical investigations and provide recommendations for surface preparation and design of any proposed structures. o Review site specifications and revise as appropriate for site-specific requirements. o Sample Groundwater and analyze the data to comply with FDEP Generic Permit for Groundwater Discharge. The laboratory analyses shall be completed in accordance with FDEP's Standard Operating Procedures (SOPs) and performed by a State of Florida certified laboratory. o Identify any areas of suspected soil and/or groundwater contamination. Address required mitigation for dewatering and pipeline installation in design and bid documents. Topographical Survey & SUE o A topographic survey in accordance with current standards of ASCE 38-02 Quality Level B shall be performed, in addition to a boundary survey. The survey shall include both sides of roadways along the project route and shall include all utility locates within the project area. o The Surveyor shall locate existing trees and determine the size and species of existing trees. o The Surveyor shall prepare a final AutoCAD survey meeting the standards set by CITY and Engineer. Signed and sealed copies will be provided for documentation. o The Surveyor shall provide sketches and legal descriptions for any easements needed as a result of the chosen route. o Engineer shall provide the following survey information using a subconsultant field service: o A subsurface survey in accordance with current standards of ASCE 38-02 Quality Level A will be performed. o Subsurface exploration will be performed at the locations identified during the development of the force main route. DESIGN AND PERMITTING SERVICES 60% Design Submittal o Preparation of a final force main route showing force main location, potential utility conflicts, roadways, and demolition areas. o Confirmation of the location of air release valves o Coordination of any Roadway and Drainage replacement. No drainage design is included in this scope of work. o Compliance with the CITY Water and Wastewater Standard Specifications. o The Design Engineer will provide a draft Technical Specifications package, including a measurement and payments section, to accompany the 60% Design Submittal. 90% Design Submittal o The Engineer shall work with their sub-consultant to review any comments resulting from the 60% design review and provide a 90% Design Submittal. The Engineer shall meet with CITY to review the ninety percent (90%) Design and discuss comments. The documents submitted at the ninety percent (90%) level will be essentially a completed design, pending final QA/QC review. o The 90% Design Submittal plan set will be used to obtain the required permits. o The Engineer will create and provide an Engineer's Opinion of Probable Construction Cost ("EOPCC") based on 90% Design. Permitting Assistance FDEP Force Main Permit Application: Permitting for force mains in Port St. Lucie greater than twelve (12) inches in diameter is administered by Florida Department of Environmental Protection (FDEP). Engineer shall prepare applications for permits as may be required and related to the facilities to be designed under this Contract. Permit-related work shall include furnishing required reports, data, drawings, and other information requested; and assisting CITY in submitting the required permit applications. Engineer shall submit permit applications to CITY for review and meet with CITY as required (estimated to be one (1) meeting) to discuss CITY's review comments. The Engineer shall revise the applications as appropriate and submit them to the appropriate regulatory agencies for review.
