How do you prepare a Bill of Quantities (BOQ) for a large construction project?

Question

Accepted Answer

To make a BOQ for larger construction work, one must accurately estimate quantities of materials and labor required for each aspect of the project.

Break down the project into smaller components such as foundation, superstructure, finishes, etc.
Calculate the quantities of materials needed for each component based on the project drawings and specifications.
Estimate the labor hours required for each component based on the complexity of the work and productivity rates.
Use unit rates for materials and labor to calculate the total cost for each component.
Sum up the costs of all components to get the total project cost in the BOQ.
