AECOM seeks a seasoned CAD Draftsman – Civil 3D with 14–16 years of experience—preferably gained on major airport developments—to deliver high-quality airside and landside stormwater-drainage designs. Operating on a 12-month contract, you will translate complex hydrologic/hydraulic analyses into constructible, regulation-compliant CAD deliverables that optimize airport operations, safety, and resilience. 

Key Responsibilities 

• Lead production of detailed Civil 3D drawings for runway, taxiway, and apron drainage, culverts, channels, detention/retention basins, and pump-station layouts. 

• Integrate grading, earthworks, and utilities considerations to create clash-free, constructible designs. 

• Build and calibrate models (e.g., Rational Method, SWMM, HEC-RAS) to simulate rainfall-runoff processes, flood routing, and system capacities unique to airport environments. 

• Interpret model outputs and iterate designs to meet hydraulic performance targets. 

• Embed ICAO, FAA, and local airport-authority drainage/safety standards (e.g., runway/taxiway infiltration limits, RESA grading, wildlife hazard minimization) into design deliverables. 

• Prepare compliance matrices and support regulators’ approvals. 

• Interface daily with airside civil, geotechnical, utilities, and structural teams to resolve drainage-pavement interactions and protect critical underground services. 

• Facilitate design reviews, clash-detection sessions, and BIM coordination meetings. 

• Produce detailed drainage plans, profiles, sections, and 3-D models; develop technical specifications, quantity take-offs, and Bills of Quantities (BoQs). 

• Compile calculation reports and presentation materials for client and stakeholder workshops. 

Bachelor’s or Master’s Degree in Civil Engineering or Environment Engineering. 

14–16 years of progressive CAD drafting/design experience, with a minimum of 8+ years dedicated to aviation (airports) drainage or airfield civil works. 

Proficiency in Autodesk Civil 3D (surfaces, corridors, pipe networks, sheet set management). 

Hands-on use of H&H software (Rational Method tools, EPA SWMM, HEC-RAS or equivalent).
