Licensed Civil Engineer with 20+ years of construction experience across technical office, QS/estimation, planning and scheduling, cost control, procurement, design/drafting, and site/contractor operations in the Philippines and Saudi Arabia. I handle quantity takeoff, BOQ/BOM, bid estimates, progress and variation measurement, AutoCAD markups, Excel cost sheets, Primavera P6/MS Project schedules, structural/architectural documentation, BBS/shop drawings, and technical coordination. My work is traceable: calculation sheets, marked-up drawings, assumptions, and revisions are kept for review. I can support remote contractors and consultants as QS/Estimator, Technical Office Engineer, Planner/Cost Control support, or CAD/engineering operations support.
