Preliminary estimate
Correct Answer:
A. Detailed estimate
Explanation:
A detailed estimate is considered the most reliable because it involves a comprehensive and systematic analysis of all project components. Unlike preliminary or area-based estimates that rely on broad historical averages, a detailed estimate utilizes complete architectural drawings and technical specifications to perform a precise quantity takeoff. By itemizing specific costs for materials, labor, equipment, and overhead, it provides the most accurate financial projection, typically achieving an accuracy range of ±5% to ±10% at the final design stage.
