• Detailed construction drawings, building sections, elevations, and permit packages.
• Automated Bar Bending Schedules (BBS) and reinforced concrete detailing.
• Structural modeling and FEA checks (Autodesk Robot Structural Analysis, ProtaStructure, and MIDAS Civil/midasGen per Eurocode 2 and BS 8110).

3. Civil Infrastructure & Earthworks:
• Autodesk Civil 3D terrain modeling (TIN surfaces, LiDAR point clouds, GPS survey points).
• Horizontal & vertical road alignments, superelevation transitions, custom assemblies, and 3D corridors.
• Earthwork volumetric cut/fill calculation (Average End Area & Prismoidal methods) and Mass Haul Diagrams.
• Gravity stormwater drainage networks and pressurized piping systems.

4. Construction QA/QC & Digital Geomatics:
• Full compliance with ISO 9001 (Quality), ISO 14001 (Environment), ISO 45001 (Occupational H&S), and ISO 19650 (BIM Information Management).
• Inspection & Test Plans (ITPs), material laboratory testing audits (concrete, soils, asphalt, steel), and high-precision geodetic setting out.

I combine real-world site construction supervision with cutting-edge digital BIM workflows. Every drawing and 3D model is produced for practical constructability, exact tolerances, and zero clash errors.
