A Bill of Quantities (BOQ) and a Material Requisition Plan are essential tools in construction planning. They help you estimate costs, plan procurement, and control resources effectively.
🔹 1. What is a BOQ?
A BOQ is a detailed document that lists the quantities of materials, labor, and other work items required to complete a project. It helps:
- Estimate total project cost
- Get fair and comparable bids from contractors
- Plan for procurement and budgeting
🔹 2. Steps to Create a Bill of Quantities (BOQ)
a. Study Project Drawings & Specs
- Review architectural, structural, and MEP drawings.
- Read project specifications for material standards and methods.
b. Break Down the Project into Work Items
Use the Work Breakdown Structure (WBS) to divide the project into sections:
- Site work
- Foundation
- Superstructure
- Roofing
- Finishes
c. Measure Quantities
- Volume (m³) – for concrete, excavation
- Area (m²) – for flooring, plaster
- Length (m) – for rebar, wiring
- Number (pcs) – for fixtures, doors
d. Use a Standard Format
Organize the BOQ in a table like this:
| Item No | Description of Work | Unit | Quantity | Unit Rate | Total Cost |
|---|---|---|---|---|---|
| 1 | Excavation | m³ | 100 | $10 | $1,000 |
| 2 | Concrete (Footing) | m³ | 50 | $80 | $4,000 |
| 3 | Reinforcement (Rebar) | kg | 500 | $1.20 | $600 |
🔹 3. What is a Material Requisition Plan?
A Material Requisition Plan is a document that outlines the materials needed for each phase of the project, with delivery timelines. It helps ensure materials are available when needed, avoiding delays.
🔹 4. Steps to Create a Material Requisition Plan
a. Use the BOQ as a Reference
- Identify all materials listed in the BOQ.
b. Match Materials to Project Schedule
- Link material needs to construction phases (e.g., cement needed during foundation phase).
c. Create the Material Schedule Table
| Material | Quantity | Required Date | Delivery Lead Time | Supplier | Status |
|---|---|---|---|---|---|
| Cement | 300 bags | June 10 | 3 days | ABC Co. | Pending |
| Rebar | 2 tons | June 12 | 5 days | XYZ Ltd. | Ordered |
🔹 5. Tips for Accuracy
- Use digital tools (like Excel, PlanSwift, or Bluebeam) for take-offs and tracking.
- Double-check quantities with engineers.
- Coordinate with the procurement and site teams.
✅ Benefits
- Helps control project cost
- Ensures timely procurement
- Improves planning and reduces material waste
- Increases contractor transparency
