Accurate quantity takeoffs & cost estimation

Leverage BIM-based quantity extraction and expert cost estimation to bid with confidence, control budgets, and maximize project profitability.

Estimation & QTO Services

Precision Quantities, Reliable Budgets

Accurate quantities and cost estimates are the foundation of successful projects. Our BIM-integrated approach extracts material quantities directly from coordinated models, eliminating manual errors and providing a clear picture of project costs from concept through construction.

Whether you're preparing a conceptual budget, bidding a project, or tracking costs during construction, our estimation services deliver the accuracy you need.

How a takeoff is produced

Schema and schedule verification first, because a takeoff is only as good as the data behind it.

Requirement capture

Which elements, which parameters, which host behaviour, which schedules they must drive, and the standard they must follow.

Template and parameter schema

Shared parameters, type catalogues and naming agreed before anything is built, because a parameter renamed later breaks every schedule using it.

Build

Families and templates built to the agreed schema, with geometry resolved at the detail levels they will actually be viewed in.

Flex testing

Each family is flexed through its parameter range and hosted in a real project condition, so it fails here rather than in your live model.

Schedule verification

We confirm the content reports correctly into the schedules and takeoffs it was built to feed, which is the only test that matters for QTO.

QA and documentation

Independent check against the schema and naming, with a short usage note so your team knows how each piece is meant to behave.

Library delivery

Content delivered into your library structure, ready to load, with the parameter schema documented.

What you actually get

A takeoff is only as good as the model data behind it.

Reviewed by a registered architect

Aercon is architect-led — a registered architect oversees delivery, so your model is questioned on design and constructability, not only geometry. Sealing and professional responsibility stay with your professionals of record.

Parameter schema agreed before anything is built

Shared parameters, type catalogues and naming are fixed first. A parameter renamed later breaks every schedule that depends on it.

Flexed before you ever see it

Each family is driven through its parameter range and hosted in a real project condition, so it fails on our machine rather than in your live model.

Verified against the schedules it feeds

Content is checked to confirm it reports correctly into the schedules and takeoffs it was built for — the only test that matters for quantity data.

Your template, not ours

We work inside your template, shared parameters, naming convention and BIM Execution Plan. Nothing comes back needing to be re-mapped to your standard.

Your drawings stay yours

NDA before we receive anything, access limited to the named project team, and we never reuse a client's models, families or drawings for anyone else.

Frequently Asked Questions

BIM-based takeoffs are typically 95-99% accurate when working with well-developed models. Unlike manual takeoffs that rely on interpretation, model-based extraction captures exact quantities embedded in the design. We validate all outputs against drawings and provide detailed breakdowns for verification.

We utilize industry-standard databases including RSMeans, Craftsman, and regional cost data tailored to your project location. For specialized work, we incorporate historical data from similar projects and current market pricing from subcontractor networks.

Yes, we offer conceptual estimates based on parametric modeling, historical benchmarks, and cost-per-square-foot data. As the design develops, we refine estimates to reflect greater detail, providing budget confidence at every phase.

We deliver takeoffs in Excel, PDF, and direct integration with estimation software including Sage, Bluebeam, and custom formats. Our outputs are organized by CSI MasterFormat, Uniformat, or your preferred categorization system.

Our BIM-based approach makes change management efficient. When designs update, we re-extract quantities from the revised model and provide comparison reports highlighting quantity and cost impacts. This enables informed decision-making during value engineering.

Yes, we prepare detailed scope breakdowns and quantity packages for subcontractor bidding. Our outputs clearly define scope boundaries, helping you obtain accurate and comparable bids from trade partners.
