Get Accurate, Model-Based Quantity Takeoffs for Any Scale of Project
From early estimates to detailed BOQs, our QTO services empower your planning, procurement, and budgeting with BIM and automation tools.
What is Quantity Takeoff (QTO)?
Quantity Takeoff is the process of calculating quantities of materials, components, or labor from construction drawings or models. It's the foundation for:
Budgeting & cost estimation (5D BIM)
We integrate cost data with BIM models to generate real-time, accurate budgeting insights throughout design development, reducing cost overruns and improving financial planning.
Tender documentation (BOQ creation)
We extract quantities from BIM models to generate precise Bill of Quantities (BOQs), ensuring clear, transparent, and competitive tender documentation aligned with project scope.
Procurement & vendor negotiation
We support procurement workflows by identifying required materials early, enabling better vendor comparison, pricing transparency, and negotiation leverage using BIM-derived data and schedules.
Construction planning and control
We align cost, time, and model data for streamlined planning, progress tracking, and dynamic updates, enabling better decision-making and construction management.
Types of Quantity Takeoffs We Offer
| QTO Type | Description |
|---|---|
| 2D Drawing-Based QTO | Manual/automated takeoffs from DWG/PDF plans using advanced measurement tools. |
| 3D BIM-Based QTO | Smart extraction from Revit/IFC models, mapped to elements and families. |
| Trade-Specific QTO | MEP, Structural, Architectural-specific quantities with classification. |
| Estimation Linked QTO | Integrated with cost databases (CostX, Excel) for 5D planning. |

Key Benefits of Model-Based QTO
High Accuracy: No manual error; quantities directly linked to model geometry
Faster Turnaround: Automation drastically reduces estimation time
Cost Impact Visibility: Integrated with 5D cost models for budget forecasting
Procurement-Ready Outputs: Grouped and tagged items aligned with vendor needs
Change-Responsive: Instant updates to quantities with model/design changes

Need help?
In this section, you can address common questions efficiently.
Can I share only drawings for QTO?
Yes, we accept PDFs, DWGs, scanned drawings—our team can still deliver accurate takeoffs even without BIM models.
How fast can I get takeoffs?
Delivery depends on scope. Most small to medium projects are completed in 3–5 working days after data submission.
Do you provide BOQs with costing?
Yes, we optionally link quantities to cost databases or client rates for a full estimation and budgeting output.
Can you use our custom BOQ format?
Absolutely. We can structure QTO data based on your preferred templates, including NRM, CSI, or internal codes.
How are changes in drawings handled?
We provide revision logs and update the takeoff accordingly—only differential updates are charged after initial delivery.
Is QTO available for landscape or interiors?
Yes, we handle landscape and interior-specific QTOs including finish schedules, furniture, softscape, and detailed material breakdowns.
