HBC Engineering Company | 108 Feng Liu, PE STRUCTURAL ENGINEER marking upgrades, utility adjustments, subsurface utility engineering services, hydraulic modeling, and environmental and drainage permitting. WB SR 924 Ramp over SR 821 (HEFT), US 27, & Miami Canal CLIENT Greater Miami Expressway Agency (GMX) I ROLE Bridge Design Engineer Responsible for the final superstructure design of Bridge 1 (WB/SB) and QC checks of superstructure designs of Bridge 2 (EB/NB). The superstructure designs encompassed Unit 2 of Bridge 1 (total length of 972’-0”), consisting of two (2) curved steel box girders of continuous 4-span (234’-0”, 347’-0”, 119’-0”, & 192’-0”), supported on hammerhead piers founded on precast/prestressed concrete piles. The CSiBridge program was used in the analysis and design of the curved steel box girders, and the reactions of dead load and live load from CSiBridge were utilized for the designs of substructures and foundations, accounting for the effects on load distribution between girders due to bridge curvature and the stiffness of cross frames and diaphragms of the steel bridge. The QC for Unit 2 of Bridge 2 (total length of 665’-4”), consisting of two (2) curved steel box girders of continuous 3-span (317’-0”, 184’-4”, & 164’-0”), included independent CSiBridge model checks to validate the design results. NW 17th Avenue over Miami River PD&E Study CLIENT DTPW I ROLE Engineer of Record/Assistant Structure Manager Responsible for evaluating the existing bridge conditions and developing conceptual bridge designs for the fixed spans of the bascule bridge and the flyover at NW 17th Avenue, as well as developing typical bridge sections. Responsibilities also included preparing a pre- engineering report, overseeing conceptual bridge design, and coordinating with other disciplines. General Engineering Service CLIENT Miami-Dade Aviation Department I ROLE Structural Engineer Responsible for various engineering tasks including QC of the bridge inspection report, review of design development of building structure, review of repair and strengthening design of MIA North Terminal Guideway with piers deterioration due to alkali-silica reaction (ASR), inspection and structural assessment report for fire damage on parking garage (MIA Bldg. 33074), inspection and structural assessment report on the existing steel framing in American Airline Hanger (MIA Bldg. 33095), independent calculations for fl exural capacities for existing Pier 64 at MIA Nort Terminal Guideway (using strain compatibility method). Districtwide Structural Projects Design and Review Consultants CLIENT FDOT District 6 I ROLE Bridge Lead Engineer Responsible for review of plans including Category 2 bridges, walls, miscellaneous structures, permit, PER, and CSI at home office; In- house consultant at District 6 responsible for bridge load rating, bridge rehabilitation design, review of plans/shop drawings/permit/scope/Technical Momo, design and QC of walls and miscellaneous structures. GGI SR 7 over I-95 and Ramp U Bridge CLIENT FDOT District 6 I ROLE Bridge Lead Engineer and Project Manager Lead Bridge Engineer and PM for the design of the bridge, MSE walls, and combination walls. This bridge is a 3-span (102.82 feet, 92.31 feet, and 105.90 feet) concrete bridge with complex geometry, including severe skew, curved alignment, and splayed beam layout. The combination walls include steel pipes and sheet piles with concrete fascia along with custom-designed framing to accommodate drainage structures. Hiatus Road Bridge Over C-13 Canal CLIENT Broward County Highway Construction & Engineering Division I ROLE Engineer of Record and Lead Bridge Engineer Provided final design and post-design services for a new 105-foot, three-span bridge carrying Hiatus Road over the C-13 Canal. The bridge accommodates two traffic lanes and 6'-6" sidewalks in each direction. The superstructure consists of prestressed concrete slab units with a 6.5-inch cast-in-place concrete topping supported by pile bent substructures. The project also included retaining walls, canal slope protection, and South Florida Water Management District (SFWMD) maintenance access ramps.
