The short version

  • Each has a real cost: On-Screen Takeoff perpetual licensing is no longer offered on current releases, so long-standing users who paid once now face a recurring annual cost they never budgeted, and staying on an old version means no support for newer PDF formats; Tekla Structures no specific pricing published; three subscription options available but require sales contact
  • They diverge on capability: On-Screen Takeoff covers Drawing takeoff, Tekla Structures covers 3D structural modeling.
  • Prices and features above were last checked on 1 September 2026.

  • A flooring subcontractor maintaining reusable conditions with waste factors so quantities and material orders stay consistent between estimatorsnot Tekla Structures
  • A trade contractor that wants takeoff quantities split by phase so progress billing matches the way work is actually releasednot Tekla Structures

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

On-Screen Takeoff

  • Perpetual licensing is no longer offered on current releases, so long-standing users who paid once now face a recurring annual cost they never budgeted, and staying on an old version means no support for newer PDF formats
  • ConstructConnect does not publish a price, and the product is increasingly sold inside a bundle with lead data and estimating, so buyers who want takeoff alone often find the quote priced around a package they do not need
  • It is Windows desktop only, with no macOS version and no meaningful browser or tablet workflow, which rules it out for firms standardised on Apple hardware
  • The interface has changed little in years and estimators coming from browser-based tools find the condition setup and layer management slow to learn, so onboarding a new estimator takes longer than the software cost would suggest
  • ConstructConnect sells lead data, takeoff and estimating as a portfolio and has consolidated several acquired products, so a buyer committing to On-Screen Takeoff should ask directly where it sits against the newer cloud takeoff products in the same portfolio

Tekla Structures

  • No specific pricing published; three subscription options available but require sales contact
  • Flexible licensing that adjusts as company develops and grows, but specific rates not disclosed

Answered from the vendors’ own pages

On-Screen Takeoff: Can I still buy a perpetual licence?

No. Current releases are annual subscription. Older perpetual licences continue to run but do not receive updates.

Tekla Structures: Is there a free trial for Tekla Structures?

Yes, a 30-day free trial is available at https://download.trimble.com/tekla-structures/free-trial

On-Screen Takeoff: Is it sold separately from Quick Bid?

It can be, but ConstructConnect increasingly quotes it as part of a takeoff and estimating package. Ask explicitly for standalone pricing if that is what you want.

Tekla Structures: What subscription options are available?

Tekla Structures offers three material-independent subscription options designed for specific user needs. Each subscription includes Trimble Connect Business Premium and Tekla Model Sharing collaboration platform. Contact Tekla for specific pricing and plan details.

On-Screen Takeoff: Does it run on a Mac?

Not natively. It is a Windows application and Mac users run it under virtualisation, which is unsupported in practice for large drawing sets.

On-Screen Takeoff: Will it read a scanned drawing?

Yes, but measurement accuracy on a scanned raster set depends entirely on the scan quality and on setting scale from a verified dimension.
