Purpose: The purpose of this Task Order is to authorize and direct CONSULTANT (Constantine Engineering, Inc.) to proceed with professional engineering services for providing subsurface utility engineering (SUE) services to the Okaloosa County Water and Sewer Department (COUNTY). The activities that are included are described in “Article B. Scope of Services.” Article B. Scope of Services: The CONSULTANT agrees to furnish general professional engineering and technical services that are applicable to the Okaloosa County Water and Wastewater System Subsurface Utility Engineering Services Project (PROJECT), as requested by the COUNTY’s representative. The services that the CONSULTANT agrees to furnish as part of this Task Order include, but are not limited to locating, verifying the location, installing permanent markers, and acquiring data for components of the COUNTY’s water distribution and wastewater collection systems. Specific work tasks that may be authorized by the COUNTY ’s representative are presented below. Task 1. Water and Sewer Asset Subsurface Utility Engineering Services CONSULTANT shall perform Quality Level A or B subsurface utility location verification services in accordance with the American Society of Civil Engineering (ASCE) Standard 38-02 entitled Standard Guidelines for the Collection and Depiction of Existing Subsurface Utility Data, Underground Facility Damage Prevention and Safety Act, Florida Statute 556, Sunshine State One-Call of Florida Requirements, and the Standard Operating Procedures (SOPs) for Subsurface Utility Locates for the Okaloosa County Water and Sewer Department (Attachment A). These services shall be performed for the PROJECT based on criteria developed with the COUNTY. CONSULTANT shall identify, interpret, verify, and field-mark buried water and sewer pressure pipelines and valves (assets) using ground penetrating radar (GPR), vacuum excavation, global positioning system equipment (GPS), and existing information and data available from the COUNTY. Specifically, CONSULTANT shall perform the following services: 1.1 Attend meetings as requested by the COUNTY’s representative to identify the proposed work areas and to review existing drawings, plans, and other information and data provided by the COUNTY of the proposed work to evaluate the locations of buried water and sewer assets. 1.2 Initiate a Florida One-Call Ticket for the proposed work areas in a timely manner and in accordance with State of Florida Regulations. TASK ORDER 04— OKALOOSA COUNTY WATER AND SEWER SYSTEM FY 2014 SUBSURFACE UTILITY ENGINEERING SERVICES PROJECT 13 1.4 1.5 1.6 1.7 Identify the location of buried water and sewer assets in the proposed work areas using ground penetrating radar (GPR) Verify the centerline location and depth of selected buried water and sewer assets using metal probes and vacuum excavation equipment as appropriate and in accordance with criteria established by the COUNTY. A description of these two methods is presented below. 1.4.1 Metal Probes CONSULTANT shall use a metal probe to verify the location and depth below the ground surface of the centerline of select buried pipelines. If the ground is too dense to probe the pipe, a high pressure water jet or vacuum excavation may be used to verify the location of the buried pipeline. 1.4.2 Vacuum Excavation CONSULTANT shall use a vacuum excavator to excavate select buried pipelines. These pipelines shall be excavated to verify the location of the pipeline and to collect specific information about the buried pipeline, including the diameter of the pipeline, the pipeline material, and as requested by the COUNTY, the depth below the ground surface. Install permanent markers that the COUNTY can use to locate buried assets in the future. The protocol that CONSULTANT shall use to identify and mark the location of buried assets is presented below. 1.5.1 Buried Pipes Under Asphalt or Concrete Buried assets located under asphalt of concrete shall be marked with a blue or green paint stripe. CONSULTANT shall not perform subsurface verification activities, but shall install a permanent marker to identify the location of the buried asset by installing an 8- or 12-inch long galvanized spike (nail) with a 5/8-inch galvanized washer. 1.5.2 Buried Pipes Under Sand or Grass Buried assets located under sand or vegetation (grass, weeds, sod, etc.) shall be marked using either a blue or green paint strip. CONSULTANT shall verify the location of the buried asset using a metal probe or vacuum excavation and shall install a 12-inch diameter, 12-inch long rebar with an orange OCWS identification button provided by the COUNTY. The rebar marker shall be driven into the soil above the centerline of the pipeline to a depth of about 2 inches below the natural ground surface. 1.5.3 Buried Valves Water valves buried under asphalt or concrete shall be marked with blue paint. CONSULTANT shall identify the spatial location (Northing and Easting) of buried water and sewer assets using real-time corrected (Omni-Star) sub-meter GPS equipment. Location information shall be stored in a digital storage device that is capable of uploading the information into the COUNTY’s geographic information system (GIS). CONSULTANT shall collect information and data about buried water and sewer assets using digital storage equipment and pipeline diameter measuring tools. Specific information and data that shall be collected will be in accordance with the established GIS data storage protocol. Some information and data listed in the Data Dictionary are not available from field investigations and will not be collected. The data collected in this task shall be stored using a digital storage device that can be uploaded into the COUNTY ’s GIS system. COUNTY supplied software may be required to fully convert the data into files for final conversion in the COUNTY’s GIS. Task 2. GIS Inventory Mapping CONSULTANT will collect information and data including horizontal data, component locations (x, y coordinates) for fire hydrants, master water meters, water service meters, water storage tanks, water wells, valves, and other appurtenances, pressure sewer air-relief valves, valves and other sewer appurtenances requested by the COUNTY’s representative. Specifically, CONSULTANT shall perform the following services: TASK ORDER 04— OKALOOSA COUNTY WATER AND SEWER SYSTEM FY 2014 SUBSURFACE UTILITY ENGINEERING SERVICES PROJECT 2.1 CONSULTANT will perform a geospatial mapping survey and inventory of water and sewer assets in the proposed work areas identified by the COUNTY’s representative. This activity includes physically locating the specific components of the water and sewer systems and recording their horizontal locations using a real-time corrected (Omni-Star), sub meter GPS equipment. The components of the water system to be inspected and located using GPS include fire hydrants, master water meters, water service meters, water storage tanks, water wells, and valves and the unknowns indicated in the existing COUNTY GIS database. Task 3. Manhole Mapping CONSULTANT will perform general manhole mapping and collect information and data including horizontal data, component locations for sewer manhole rim elevations and manual tape reading of line inverts at manhole and lift station junctions. Specifically, CONSULTANT shall perform the following services: 3.1 CONSULTANT will take digital photographs of each manhole using a specialized camera extension, “camera ona stick.” This information will be used to provide pipe types, pipe diameter and flow directions. In addition, observations will be made to determine if any opposite flow or flat grade sewers are present. 3.2 No manholes will be physically entered by field inspection personnel. 3.3 Manhole in-flowing and out-flowing pipe elevations will be manually obtained and measuring from the manhole rim elevation using a tape measure with 0.1 feet accuracy. A manhole diagram will be prepared showing all pipe entrance, sizes, depths and their respective angles from noted reference mark on rim. Task 4.
