Cost Estimate Techniques include which of the following?

• A. Order of Magnitude
• B. Bottom-Up Analysis
• C. Life Cycle Costing
• D. Feasibility Study

Answer: (A)

Estimating costs early in a project relies on quick, broad methods that give a general sense of budget without detailed design data. An Order of Magnitude estimate is the fastest technique, producing a rough cost range from limited information by using historical data, cost indices, or scaling from similar projects. It’s specifically used to screen feasibility, set rough budgets, and compare alternatives before the design is developed in detail. Bottom-Up Analysis, by contrast, builds the cost from the ground up using detailed quantities and piece-by-piece pricing, which requires a mature design and more time. Life Cycle Costing looks at total ownership costs over the asset’s life, including operations and maintenance, not just the initial construction cost. A Feasibility Study assesses viability and practicality, and while it may include cost considerations, it isn’t a dedicated estimating technique itself. Therefore, the appropriate choice for cost estimate techniques in this context is the Order of Magnitude estimate.
