Types of Preliminary Estimates for Every Project Phase
ROM Estimates
Our ROM (Rough Order of Magnitude) estimate helps answer the question “Is this project worth the investment?” When little more than a concept exists, we provide dependable ROM estimates. These estimates are typically based on historical data or similar projects. While not highly detailed, they give you a realistic idea of whether or not a project is feasible. The accuracy range of our ROM estimate is between -50% to +50%.
Budget Estimates
1800 Estimating offers precise budget estimating services during the planning phase of the construction project. Our team analyzes the plans and blueprints and uses data from past projects. Thus, creating budget estimates that contain detailed line items for labor and material prices. Moreover, budget estimates have an accuracy range from -10% to +25%.
Ballpark Estimates
These estimates are best suited for clients who need a quick cost assumption without extensive details. Ballpark estimates are often prepared in the middle stages of design. They are useful when comparing multiple design options or assessing the impact of scope changes. Our ballpark estimate’s accuracy falls within 20% of the actual cost.
Definitive Estimates
As the project comes to the final design phase, we prepare definitive estimates with the highest level of accuracy. These cost estimates are made by reviewing complete drawings, detailed blueprint takeoffs, and updated pricing for every material. It offers accuracy within a range of -5% to +1 (619) 912-93905%.
