What are the main sections of bill of quantities?

The main sections of a Bill of Quantities (BoQ) typically include the preamble, which outlines the document's purpose and general conditions; the measured works section, detailing quantities and descriptions of materials and labor required for the project; and the pricing section, where contractors provide their cost estimates for each item. Additional sections may include summary tables, site information, and specific trade sections to organize work by discipline. This structured format helps in accurately estimating project costs and facilitating clear communication between clients and contractors.
