Which estimating method is typically used by the architect rather than the contractor?

• A. Conceptual estimate.
• B. Rough order of magnitude.
• C. Detailed estimate.
• D. Bid estimate.

Answer: (A)

At the early design stage, architects typically provide a rough, high-level cost guide to explore feasibility and guide design decisions. This conceptual estimate uses general data like cost per square foot and project program rather than detailed quantity takeoffs, making it fast to produce and flexible as the design evolves. It helps set a budget direction without getting bogged down in exact numbers. In contrast, a detailed estimate relies on complete drawings and specifications and is prepared by the contractor to price the actual construction. A bid estimate is the price a contractor submits to win the project, usually after the design is developed. A rough order of magnitude is another early figure used to check feasibility, but the architect's conceptual estimate is the typical early-cost tool associated with the architect.
