How to Build a BOQ from Scratch: A PMC's Step-by-Step Guide

A Bill of Quantities (BOQ) is the foundation of construction project costing. Getting it right from the start prevents disputes, ensures accurate bidding, and provides a clear framework for project execution.

Start with a thorough review of all project documentation: architectural drawings, structural plans, MEP layouts, and specifications. Missing items at this stage will cause problems throughout the project lifecycle.

Break down the work into logical sections following standard measurement methods. In most regions, this means following local standards or international methods like SMM7 or NRM2.

For each item, include a clear description, unit of measurement, quantity, rate, and amount. Be specific about inclusions and exclusions to prevent scope disputes later.

Use software tools to automate calculations and ensure consistency. Modern BOQ software can link directly to CAD drawings and update quantities automatically as designs change.
