Ruben Mesa Records), Located Transit utilities serving the Metrorail system, Locate all other non-Transit utilities within the corridor. Located two FPL 13.2KV power feeds serving each station (four lines total). Located the FDOT fiber optics communications line installed along the corridor. Dates of Service 05/2023 to Ongoing. MIAMI-DADE WATER AND SEWER DEPARTMENT NORTH DISTRICT WWTP ELECTRICAL DISTRIBUTION BUILDING Coordinated and supervised the field operation for Subsurface utility investigation performed to determine approximate location of existing underground utilities at potential utility crossings. Subsurface utility investigation included the following: • Vacuum Excavation and Location: Perform underground utility location to verify through vacuum excavation the horizontal and vertical position of existing underground utilities at the locations selected, report indicating the underground utility horizontal location, the depth, lay direction, diameter and the material for each pot hole. Included the location of each pothole on the final survey. 01/2022- 07/2023 Miami international Airport Coordinated and supervised the field operation for This project which consisted on the update and maintenance of the drainage master plans for Miami-Dade Aviation Department (MDAD) facilities. The scope of services shall include collecting and reviewing as-built data, field verifying as-built conditions, updating the utility atlas, updating the existing modeling scenario, re-establishing the future modeling scenarios, updating the master plan documents, reviewing and updating the MDAD design guideline, reviewing and updating the technical specifications and assisting the Department with environmental and permitting issues Provided Surveying Services for the Miami-Dade Aviation Department Storm Sewer Master Planning, CDM PN 278874 – MIA Stormwater Model Update Field Verifications Performed Location and Existence Verification of Sites located within Miami International Airport. Located all sites in question with GPS, Dates of Service 06/2023 – 08/2023 Miami-Dade County Contract E15-PWWM-07 Project 20170037 Successfully completed a comprehensive topographic survey project in Miami-Dade County. The project encompassed various tasks, beginning with establishing the centerlines of rights-of-way. These centerlines were based on existing Plats or fractional lines if adjacent properties were not platted. The project also involved showing right-of-way lines according to Public Records for the project area. To ensure accurate measurements, a physical control baseline was established using the center lines of the right-of-ways. Additionally, the project required establishing a site benchmark in the NGVD 1929 elevation datum. This benchmark served as a reference point for elevation measurements. The survey team then meticulously located all topographic data approximately 50 feet beyond the PC (Point of Curvature) of the radius returns along all intersecting streets. To account for drainage systems, the surveyors identified and located all drainage structures, recording details such as the size of the structures and drainage pipes’ inverts, elevations, and size. Furthermore, the project involved locating all existing mast arms, including their lengths and sizes. To gather comprehensive data, cross- section measurements were collected at 25-foot intervals. The team ensured that all data was recorded in state plane coordinates and overlaid on an aerial photograph, facilitating precise mapping and analysis. The surveyors also accounted for overhead wires, meticulously locating them and determining ground clearance at the maximum sag point. In addition to the survey data, the project required denoting the origin of control points, either within the survey documentation or a separate report. Similarly, the origin of vertical control was specified, and copies of the fieldwork were provided to ensure transparency and traceability. Overall, Hadonne executed the project with precision and expertise, delivering a comprehensive and accurate topographic survey. The data collected will serve as a valuable resource for future planning and development initiatives in the Miami-Dade County area. Dates of Service 07/2019 -01/2020. 39
