Which estimate type is prepared with the aid of flow sheets and layouts?

The type of estimate prepared with the aid of flow sheets and layouts is correctly identified as budget estimates. These estimates typically incorporate detailed information gained from flow sheets and layout designs, which are critical for understanding the scope of work, process flows, and material requirements in projects, especially in fields such as construction, manufacturing, and engineering.

Budget estimates are prepared to provide a more comprehensive overview of the anticipated costs of a project by considering the layout and workflow. This thoroughness helps ensure that all necessary components, labor, materials, and other costs are accounted for, allowing for better financial planning and resource allocation.

Other estimate types such as definitive estimates, order of magnitude estimates, and Class 3 estimates serve different purposes and are based on varying levels of detail and accuracy. Definitive estimates are typically more detailed but may not always utilize flow sheets to the extent that budget estimates do. Order of magnitude estimates are very preliminary and lack the detail provided by flow sheet analysis. Similarly, Class 3 estimates refer to a specific level of detail based on a defined set of parameters and may not directly involve the use of layouts and flow sheets as foundational components.
