I am a Civil Engineer with five years of experience in quantity estimation, site engineering, and construction coordination across earthworks, structural works, and architectural works. I use AutoCAD, PlanSwift, and Bluebeam to perform accurate quantity takeoffs and prepare Variation Orders and Change Orders for effective project costing. I have supervised earthworks, concreting, rebar installation, masonry, structural and architectural steel works, waterproofing, and painting activities. I coordinate with project management teams, suppliers, subcontractors, architects, and structural engineers, while preparing RFAs, RFIs, and progress reports to support efficient execution, quality workmanship, and timely project completion.
