PS&E Plan Production Experience

Roadway Design Experience

• Horizontal and vertical alignments using GEOPAK and OpenRoads for various TCP temporary pavements, and smaller county road projects.
• OpenRoads model of 2 county road Projects. This includes grading, superelevation, and creating cross sections.
• OpenBridge model for a small bridge on a county road project.

TCP Experience

• Segment 1 of the I-30 Expansion/Improvement Project over Lake Ray Hubbard (Bass Pro Dr to Dalrock Rd)
• Segment 2 of the I-30 Expansion/Improvement Project over Lake Ray Hubbard (Dalrock Rd/ SH204).
• Bass Pro Dr. over I-30 - Flipping the intersection to bring I-30 over Bass Pro Dr.

All work was under the supervision of the PM. Extensive TCP design for these projects includes:

• Maintaining all existing lanes on main lanes and frontage roads, utilizing work zone striping, temporary barrier, temporary pavement, shoring, etc., and following the MUTCD and TXDOT standards.
• Producing detour plans for roadway closures and placing temporary signs and sign structures as needed.
• Design temporary drainage utilizing existing, proposed, and temporary pipes and inlets to avoid flooding during construction.
• Coordinated with TXDOT to address their comments, as well as create a Contract Time Estimate for the projects.
• Quantifying the cost of TCP operations, including temporary mobile attenuators.

Sign Plans

• Designed all of the proposed small and large guide signs for all major PS&E projects worked on, including all of the I-30 Improvement projects.
• In accordance with the MUTCD, TXDOT SHSD, TXDOT Sign Crew Field Book, and TXDOT Standards.
• Designed large guide signs in SignCAD.
• Creating Summary of Large Signs and Summary of Small Signs.
• Designed proposed sign structures under the supervision of a structural engineer.

Signal Plans

• Worked in tandem with a Traffic Engineer, PE, to design various signals for multiple intersections on various projects. The most significant being the I-30 Improvement Project (I-635 to Bass Pro Dr) included 4 intersection signal designs.
• Designed the signal heads, conduit runs, conductor runs, signal phasing, pedestrian poles, and signing.

Illumination Plans

• Currently working on a high mast illumination plan for the I-30 Project in Malvern, Arkansas under the supervision of a PE. Designed with illuminance method using AGI32 Illumination software, per the AASHTO Illumination Manual.
• Designed Illumination Plan for I-30 Project (I-635 to Bass Pro Dr).
• Designed Illumination Plan for small Texas Plaza Project in Irving, Texas.
• All Illumination Plans include conduit runs, conductor runs, electric service tables, and wiring diagrams.

• Varies engineering tasks for a concrete pipe and culvert plant
• Collected concrete cylinders for testing.
• Conducted slump test for the concrete mix for each day.
• Added air entrainment for special culvert/bridge products produced.
