What Is a Preliminary Estimate & Why It Matters?
A preliminary estimate also known as a conceptual estimate is used to forecast the potential cost of a construction project to determine its economic feasibility before detailed drawings or designs are developed. At Green Build Estimator, we help contractors, real estate developers, home builders, and owners make informed decisions about fund allocation, preliminary budgeting, and comparing design alternatives at the earliest stages.
Since preliminary cost estimates are conducted before actual design and construction, they rely heavily on historical project data carefully adjusted for time, location, and size, combined with proven engineering principles. The accuracy of these estimates depends on the level of detail available from the client.
Types of Preliminary Estimates
• Rough Order of Magnitude (ROM) Estimate – the earliest stage of estimating, used to evaluate basic feasibility and guide project selection. Accuracy typically ranges from -50% to +50%.
• Ballpark Estimate – prepared by contractors to define the scope of work for clients, helping owners align expectations with budgets. Based on preliminary drawings and specs, with an accuracy within 20% of the actual cost.
• Budget Estimate – created using data from previous projects and early plans, typically during the planning phase. Breaks down costs for major components, including materials and labor, with an accuracy of -10% to +25%.
• Definitive Estimate – also called a digital cost estimate, this is a detailed, itemized list of all project components. It’s developed from thoroughly prepared project plans and provides the highest accuracy, in the range of -5% to +15%.
