Indirect costs would most likely include which of the following?

Indirect costs are expenses that cannot be directly attributed to a specific project or product but are necessary for the overall functioning of the business. These costs support the primary activities of the construction operation but are not directly tied to construction activities themselves.

Marketing expenses are a prime example of indirect costs. They contribute to the company's ability to acquire new projects and maintain relationships with clients but do not directly relate to the labor or materials utilized on a specific job site. These expenses are considered overhead because they are necessary for running the business as a whole rather than for individual projects.

In contrast, repair costs, medical costs, and direct labor are generally classified as direct costs because they can be directly associated with specific construction activities or projects. Repair costs often relate to fixing equipment or assets used in projects, medical costs can arise from occupational injuries directly tied to workers at a job site, and direct labor costs refer to wages paid to workers who are actively engaged in construction tasks. Thus, marketing expenses correctly represent indirect costs in the context of this question.
