How many main types of material costs are identified?

In construction cost estimation, material costs are typically identified in two main categories. These categories encompass direct costs and indirect costs.

Direct material costs are associated with the physical materials required for construction projects, such as concrete, steel, and wood. These costs are straightforward to determine and are reflected directly in the project budget.

Indirect material costs may include factors such as shipping and handling, waste, and inventory carrying costs. Although these costs are not directly tied to a specific material quantity, they are essential for a comprehensive understanding of overall material expenses.

The distinction into these two main types allows project managers and estimators to effectively budget and control expenses related to materials throughout the lifecycle of construction work. Understanding this classification is crucial in ensuring accurate cost estimation and successful bid package management.
