Estimating Practice Exam

What type of costs typically make up add-ons in project estimates?

1. Unforeseen construction costs

2. Specified accessory costs

3. Indirect costs determined at the end of the estimate

4. Marketing and advertising expenses

The correct answer is: Indirect costs determined at the end of the estimate

Add-ons in project estimates typically consist of indirect costs determined at the end of the estimate. These costs are not directly attributable to a specific project activity but are necessary for the overall completion of a project. They may include expenditure for supervision, utilities, insurance, and general administrative expenses. Understanding the significance of these costs is crucial as they can greatly affect the overall budget and profitability of the project if not accurately included. The other types of costs listed do not fit the definition of add-ons as effectively. Unforeseen construction costs are usually considered contingencies rather than a planned addition. Specified accessory costs may relate to particular items or services needed for the project but do not summarize the broader indirect costs that can emerge. Marketing and advertising expenses, while essential for business operations, are typically unrelated to the direct execution of a project and thus not classified as add-ons in project estimates. This makes the understanding of indirect costs particularly important for accurate financial planning and resource allocation in project management.
