The contractor is primarily responsible for preparing the Bill of Materials because it is a crucial document that outlines the quantities and types of materials required for a construction project. This document is essential for cost estimation, procurement, and scheduling, as it allows the contractor to ensure that all necessary materials are accounted for before construction begins.

The contractor's knowledge of construction methods, material specifications, and project requirements enables them to accurately compile this information, thereby facilitating a smoother workflow during the construction phase. While other roles, such as the architect or owner, may provide input regarding material selections and design specifications, the contractor takes the lead in assembling the Bill of Materials to align with practical construction needs and logistics. This delineation of responsibilities is foundational in the successful execution of a construction project, clarifying that the contractor is tasked with managing the details essential for project delivery.
