BOM vs BOQ: What's the difference?

The terms "Bill of Materials" (BOM) and "Bill of Quantities" (BOQ) are often used in various industries, particularly in construction and manufacturing, and they serve different purposes. Understanding the differences between BOMs and BOQs can help with project planning, procurement, and execution.

Let's break down the key differences between the two:

1. Bill of Materials (BOM)

A Bill of Materials is a comprehensive list of raw materials, components, and assemblies required to build, manufacture, or repair a product or project.

Key Features:

Detail-Oriented: Includes detailed information about each component, such as part numbers, descriptions, quantities, and sometimes even the supplier details.

2. Bill of Quantities (BOQ)

A Bill of Quantities is a detailed document that itemizes all the materials, parts, labor, and costs involved in a construction project.

Key Features:

Focus on Quantities and Costs: Emphasizes the quantity of each material and the cost associated with them, often broken down into detailed line items.
