HBC Engineering Company | 123 <br />FDOT District 4, S.R. 817/University Dr Widening from Nova Dr to S.R. 84. <br />This project consisted of the widening of a 0.5-mile segment of one lane of S.R. 817/University Drive from south of <br />Nova Drive to S.R. 84. This project included the addition of a choice lane and the widening of the on-ramp connecting <br />to I-595 by one lane. Bike lane and shared-use path modifications were included within the reconstruction. David <br />was responsible for assisting with the roadway and drainage design and the development of Temporary Traffic <br />Control Plans (TTCPs). <br />Location: Davie, FL. Dates: 2022–2024. HBC Fee: $1.75M. Reference: Adham Naiem, PE, (954)-777-4440, adham. <br />naiem@dot.state.fl.us. FM# 445624-1-32-01, Contract No.: CAI67. <br />FDOT District 6, Districtwide Traffic Operations Studies Contract for S.R. 959/SW 57th Ave/Red Rd at SW <br />19th St. <br />This project evaluated the feasibility of installing a pedestrian crosswalk and determining recommendations <br />for potential improvements, in response to citizen complaints at the study intersection. David performed data <br />collection for this project, which involved 72-Hour traffic volume approach counts, 8-Hour Turning Movement <br />Counts (TMCs), and vehicle gap measurements. He also performed safety analysis, pedestrian evaluation and <br />analysis, and provided recommendations, based on the the FDOT Traffic Engineering Manual (TEM). <br />Location: Miami-Dade County, FL. Dates: 12/2020–01/2021. Reference: Xaviel Llerena, (305) 470-3935, Xaviel. <br />Llerena@dot.state.fl.us. FM# 249796-9-32-01, Contract No.: CA 139. <br />MDC-DTPW, NW 25th St Reconstruction from NW 117th Ave to NW 87th Ave. <br />This project consists of the full reconstruction of approximately 3.0 miles of the existing roadway from a 4-lane <br />road to a 6-lane road with raised median, sidewalk on the south side, shared-use path on the north side with the <br />appropriate structural supporting system for the path, due to widening into the North Line Canal, curb and gutter, <br />stormwater drainage system, signing and pavement marking, traffic signalization, roadway lighting, environmental <br />permitting, and construction administration. David is responsible for the drainage design, analysis, and permitting <br />of the proposed roadway widening improvements. <br />Location: Miami, FL. Dates: 2019–Ongoing.

He also assisted with the Synchro Analysis of <br />the project corridor. Four microsimulation scenarios were tested: base model, during construction no closure, 1 <br />lane closure, and full closure. This required balancing traffic, determining the traffic growth rate over the course of <br />construction, generating AM and PM models for each scenario, and optimizing the signal timing for each scenario. <br />Smart Work Zones (SWZs) were identified, based on the dynamic assignment of the models. <br />Location: Miami, FL. Duration: 2019–2020. Reference: Bao-Ying Wang, PE, (305) 470-5211, Baoying.Wang@dot.state. <br />fl.us. FM# 423251-2-32-01, Contract No.: C9R91. <br />FDOT District 6, Hialeah Freight Study. <br />This Hialeah Freight study was part of a regional planning effort to facilitate freight movement in Miami-Dade <br />County. FDOT District 6 investigated freight corridors within the City of Hialeah and surrounding areas, to develop <br />alternatives that enhance freight connectivity and minimize transportation conflicts. David’s primary responsibility <br />was data collection. This effort included AM peak, Mid-day peak, and PM peak weekday Turning Movement Counts <br />(TMCs) at 29 intersections. The counts were conducted at all movements for each intersection, including special <br />movements, such as fly over ramps, utilizing Miovision Scout cameras. Data collection also included volume and <br />David Coker, EI
