he purpose of estimating is to enhance bidding competitiveness and secure high-quality projects. Main tasks include preparing bid estimates and proposals, and establishing an execution budget for smooth construction progress after contract signing. Bid estimates are prepared after participating in the client’s site briefing, based on bidding drawings and specifications provided by the client. Accurate quantity take-offs and optimal pricing are essential for competitive bids. Execution budgets serve as the standard for construction and cost management. After contract signing, the estimator fully reviews all project details to ensure the timely preparation of accurate and practical budgets to secure the planned profit margin.

This role covers the entire construction process—from budgeting and planning, through scheduling, design changes, subcontractor and quality control, to project completion—based on professional knowledge in building construction, structural engineering, electrical, and mechanical systems.

Handles the ordering, bidding, and contracting of materials, equipment, and subcontractors according to the construction schedule.
