Which of the following is NOT a main cost category?

The correct response identifies transport as not being a main cost category in the context of construction cost estimation. In construction projects, the primary cost categories typically include material, labor, and equipment. These categories represent the fundamental inputs required to carry out construction activities.

Material costs encompass all physical items needed for the project, including concrete, steel, and finishes. Labor costs refer to the expenses associated with the workforce required to execute the project, including wages, benefits, and other related expenses. Equipment costs involve the purchase or rental of machinery and tools necessary for the construction work.

While transportation costs are relevant to the overall project budget, they are often considered a subset of the material or equipment costs, depending on how the project is structured. For example, the cost of transporting materials to the site may be included within the material category. In this regard, transport is typically not classified as a distinct main cost category when analyzing costs in construction projects. Understanding these cost categories helps project managers and estimators more effectively track expenses and create accurate budgets.
