1. Take-off: The first step in preparing a bill of quantities is to conduct a take-off. This involves reviewing the drawings and specifications provided by the client and identifying all the materials, labor, and equipment required for the project.
2. Measurement: Once the take-off is complete, the next step is to measure the quantities of each item required for the project. This is typically done using standard measurement units such as square meters, cubic meters, or linear meters.
3. Pricing: After the quantities have been measured, the next step is to assign prices to each item. This involves obtaining quotes from suppliers and subcontractors, as well as factoring in labor costs and overhead expenses.
4. Subtotals: Once all the items have been priced, subtotals are calculated for each section of the bill of quantities. This helps to break down the total cost of the project into manageable components.
5. Contingencies: It is important to include contingencies in the bill of quantities to account for any unforeseen circumstances or changes that may arise during the construction process. This helps to ensure that the project remains within budget.
6. Final total: Finally, all the subtotals are added together to calculate the final total cost of the project. This figure is typically presented to the client as part of the tender documentation.
7. Review: Before finalizing the bill of quantities, it is important to review the document carefully to ensure accuracy and completeness. Any errors or omissions should be corrected before submitting the tender.
8. Approval: Once the bill of quantities has been reviewed and finalized, it is typically approved by the client before the tender is submitted. This helps to ensure that both parties are in agreement on the scope and cost of the project.

Traditional Methods of Preparing Bills of Quantities (BOQs)
1. Preliminaries
- Obtain project drawings and specifications.
- Identify project scope and requirements.
- Determine measurement units and basis.
2. Measurement
- Divide project into measurable elements (items).
- Extract quantities from drawings and specifications using specific rules.
- Calculate quantities for each item using standard measurement methods.
3. Description
- Create a clear and concise description for each item.
- Include relevant details such as materials, dimensions, finishes, and installation requirements.
4. Material Calculations
- Determine material quantities required for each item based on specifications and standard formulas.
- Account for waste, shrinkage, and allowances.
5. Labor Calculations
- Estimate labor hours required for each item based on standard industry rates and crew estimates.
- Consider site conditions, productivity, and complexity of work.
6. Overhead and Profit
- Allocate a percentage markup to each item to cover indirect costs such as overhead, administration, and profit.
7. Pricing
- Determine unit prices for each item based on material costs, labor costs, overhead, and profit.
- Consider market conditions and competition.
8. Assembly
- Compile all items into a Bill of Quantities, organized by trade or subtrade.
- Assign item numbers and group related items together.
9. Review and Verification
- Proofread and verify all quantities, descriptions, and calculations.
- Obtain sign-off from relevant stakeholders (e.g., architects, engineers).
10. Finalization
- Issue the final BOQ to tenderers or contractors for bid submission.
- Provide clear instructions on how to use the BOQ and any relevant clarifications.
