What is the primary purpose of a conceptual estimate in architecture?

The primary purpose of a conceptual estimate in architecture is to assess feasibility and budget at the project's outset. This estimate serves as an early approximation of costs based on limited information and serves to help project stakeholders understand the financial implications of their ideas before investing more time and resources into detailed planning and design.

At the onset of a project, detailed plans or specifications may not yet be available, making a thorough breakdown of costs challenging. Instead, conceptual estimates rely on historical data, similar projects, and general pricing to provide a ballpark figure that helps stakeholders gauge whether the envisioned project aligns with their budget and financial goals. This early insight is crucial for decision-making, including whether to proceed, modify, or abandon the proposed project based on its feasibility.

In contrast, detailed breakdowns, securing bids, or identifying suppliers come later in the process once the project is better defined and committed to proceeding. Thus, the focus of a conceptual estimate is on early-stage assessment rather than these subsequent activities.
