He has designed and managed major projects, including regional booster stations and world record length horizontal directional drills. Julian frequently leads multidisciplinary teams and oversees all phases of project delivery, from preliminary and final design to permitting, bidding, and construction administration. He is also an accomplished author and presenter, having published and presented papers on Horizontal Directional Drill Design in South Florida at the 2023 WEF Collection Systems Conference and the 2024 No-Dig Show. Representative project experience includes: City of Miami Beach, FL, Stormwater Pump Station at Miami Beach Convention Center. Project engineer responsible for two pump stations consisting of four 20,000 GPM low-head axial pumps, water quality treatment structures discharging treated runoff directly into a duplex wet well, a long energy dissipater structure, and approximately 175 feet of new seawall following the most updated City of Miami Beach Public Works standards. This project considered the effects of sea level rise and ensured that this facility would function appropriately for the estimated design life of the project. This design-build neighborhood improvements project encompassed an area of approximately 84 acres. Julian assisted in preparing construction drawings. Miami-Dade Water and Sewer Department, FL, Miami-Dade Pump Station Improvement Program (PSIP). Project engineer. MD-WASD launched the PSIP under the terms of the consent decree. The program budget was estimated at $215 million, including 153 upgrade/refurbish projects (118 sewage pump stations and 35 Force Mains located in Miami Dade County that was out of compliance or could not deliver peak flows for their service areas. CHA was the project manager of 27 pump stations. Tasks performed by our team included data collection of existing pump stations, including hydrographs, historical hydraulic data, piping configurations, etc., to determine the best hydraulic solution. Pump stations improvements/ upgrades required an in-depth, multi-disciplinary analysis and were designed in close coordination with both Miami- Dade Water and Sewer’s Department Planning and Operations department to ensure that all proposed upgrades/additions were practical and feasible from a construction and operation point of view. Sea level rise and resiliency to climate changes were essential elements for the proposed upgrades. During the design phase, CHA analyzed the existing pump station conditions, including hydraulic, mechanical, electrical, structural, and architectural, to determine the various possibilities and implement the most practical and cost- effective solutions. Miami-Dade Water and Sewer Department, FL, 13-WASD-03 PSIP PS 0300. Project engineer for this project that consisted of rehabilitating and upgrading Pump Station 0300, an important booster facility that suffered a catastrophic disaster when a dresser coupling failed and flooded the station. CHA was selected to create a BODR and design the upgrade of the pump station, which includes five 600 HP pumps, operating in a flow range of 7,000 to 31,000 gpm, which collects sewage from a 72-inch influent pipe and discharge into a common header that joins a 48-inch force main. CHA performed several analyses of the existing conditions, including hydraulic, mechanical, electrical, structural, and architectural, to determine the various possibilities and implement the most practical and cost-effective solution.
