Infrastructure Design / CAD & Quantity Surveyor - Professional

Consulting • Full-time

May 2021 - Present • 5 yrs 5 mos

Data & Surface: Manage Civil 3D setups by processing survey data (points, contours, DEM) into surfaces. Conduct terrain analysis for roads and land development, providing volumes (cut/fill) and setting-out points for construction alignment. Civil & Roadway Design: Lead design from feasibility to geometric engineering, covering horizontal/vertical alignments and intersections. Perform corridor modeling for roads/roundabouts and optimize site grading to balance soil logistics while managing plan production and sheet set creation. Drainage & Hydraulics: Design robust stormwater networks, pipe systems, and culverts with rigorous clash detection. Develop profiles for canals and retention ponds, set finish elevations for gravity flow, and perform slope analysis to ensure long-term terrain stability and erosion control. Structures & Documentation: Design concrete pavements, culverts, side drains, and ancillary building frames. Finalize all technical drawings for submission and site execution.
