Converting Architectural, Structural, MEP Drawings, Site Survey Reports, and BOQ Formats into a Bill of Quantities (BOQ)
A Bill of Quantities (BOQ) is created by systematically extracting data from project documents and translating them into itemized quantities with pricing. Below is a step-by-step process to convert each input into a BOQ.
Electrical works (wiring, conduits, switches, panels)
Plumbing works (water supply, drainage, sanitary fittings)
HVAC works (ducting, air conditioning, ventilation)
d) Site Survey & Soil Investigation Report → Foundation & Earthwork in BOQ
🔹 What to extract?
Type of soil and excavation depth required.
Need for soil improvement or special foundation work.
🔹 BOQ Sections
Site clearing & preparation
Excavation & backfilling
Soil stabilization (if required)
e) BOQ Format & Standard Codes → Structuring BOQ Correctly
Use standard BOQ templates (FIDIC, NRM, CESMM, SMM7, etc.).
Follow measurement units (m³ for concrete, m² for tiling, kg for steel).
Ensure standard descriptions (e.g., "25 MPa reinforced concrete for footings").
2. Measuring Quantities (Quantity Take-off - QTO)
Use AutoCAD, Revit, or PlanSwift to extract exact quantities.
Manually measure from scaled drawings using rulers & formulas.
Use Excel sheets for calculations & structuring.
3. Preparing BOQ (Example Format)

4. Applying Costing & Finalizing BOQ
Get material rates from suppliers.
Use labor rates for different tasks.
Add overheads & profit margin (typically 5–15%).
Review & validate before finalizing.
Conclusion
To convert project documents into a BOQ, a Quantity Surveyor (QS) needs to:
✅ Extract relevant measurements from drawings & reports.
✅ Use standard BOQ formats for structuring.
✅ Perform accurate quantity take-offs using tools.
✅ Apply market rates for costing.
✅ Review & validate before finalizing.
This structured approach ensures accuracy and efficiency in BOQ preparation. 🚀
