On-Screen Takeoff® and eTakeoff Dimension, the takeoff product from eTakeoff, both help construction teams quantify project scope from digital drawings. The key difference is how each product organizes takeoff work and connects it to estimating.
On-Screen Takeoff emphasizes structured, estimator-controlled takeoff for plan sets, Conditions, areas, revisions, and multi-condition workflows. eTakeoff emphasizes configurable PDF takeoff, assemblies, formulas, Excel workflows, and optional connections to estimating systems such as Sage Estimating 300.
On-Screen Takeoff centers the estimator. eTakeoff centers a configurable, assembly-driven estimating workflow.
On-Screen Takeoff is a strong fit for commercial GCs and preconstruction teams that need to organize quantities across Conditions, areas, trades, repeated layouts, and drawing revisions. The Takeoff BOOST™ suite can provide AI-assisted preliminary measurement through tools such as Auto Takeoff. An estimator must review and refine the results, and feature availability depends on the applicable subscription, maintenance level, version, and rollout. Quick Bid® is an optional connection for teams that want to continue from takeoff into estimating.
eTakeoff is a strong fit for teams that need digital takeoff with configurable measurements, assemblies, formulas, variables, Excel integration, and concurrent multi-user access. eTakeoff Bridge is a separate program that eTakeoff documents as connecting Dimension with Sage Estimating 300. eTakeoff also documents a Navisworks Integrator add-on to Bridge for workflows that combine 2D takeoff with 3D model information.
Both products support digital quantity takeoff. The meaningful differences are in workflow emphasis, repeatable measurement, AI assistance, estimating connections, collaboration, and optional functionality.
Feature availability can vary by product edition, add-on, version, maintenance status, or deployment model.

Structured takeoff for complex plan sets On-Screen Takeoff organizes the takeoff process the way estimators think about it: by Conditions, areas, trades, repeated layouts, and drawing revisions. Estimators can use templates to measure repeated rooms, floors, and areas, and reuse conditions from the base bid for alternates and changes, reducing re-work on complex or phased projects. Quantities filter, sort, and group to match how teams report internally or to clients. This is a platform built around how estimators work, not how they have to adapt to the tool. What this means for you: The more complex the plan set, the more structure matters. On-Screen Takeoff gives estimators the organizing tools to stay in control of a bid, not just a drawing. |
A direct connection to Sage Estimating 300 via Bridge eTakeoff Bridge is a separate program that connects eTakeoff Dimension to Sage Estimating 300. According to eTakeoff's official Bridge documentation, the integration supports drag-and-drop measurement transfer, Sage assembly support, field mapping, review mode, changed-measurement detection, estimate updates, and drill-down from estimates back to source measurements in the plan. For teams whose estimating process runs through Sage, this gives a direct path from digital takeoff to finished estimate without rekeying quantities. What this means for you: If your estimating is built around Sage Estimating 300, eTakeoff and Bridge give you a native, traceable connection from plan measurement to finished estimate. |

A native path from takeoff to estimate through Quick Bid For teams that want to move from takeoff into estimating without leaving the ConstructConnect platform, Quick Bid is available as an optional addition. Quantities push from On-Screen Takeoff to Quick Bid in one step. Both tools are designed to work together. Teams that already use Excel or another estimating system can export quantities and keep their existing process. On-Screen Takeoff also connects to 17 accounting and estimating software platforms for teams that need broader integration flexibility. What this means for you: You can build a connected takeoff-to-estimate workflow inside one ecosystem, or stay with the tools you already have. On-Screen Takeoff works either way. |
AI measurement assistance through Snap AI and optional Togal.AI
eTakeoff Dimension includes Snap AI, which assists with precise measurement point selection in vector PDFs. It predicts likely measurement paths for faster point, line, and polyline selection, and is available to Premier subscribers. eTakeoff also offers an optional integration with Togal.AI, a third-party service that can identify area, length, and count measurements on supported architectural floor-plan PDFs. Snap AI is built into Dimension; Togal.AI is a separate service with its own subscription. What this means for you: Estimators who work from vector PDFs can move through plans faster with Snap AI. Teams that want broader AI measurement coverage can add Togal.AI as a separate integration. |
The right product is the one whose trade-offs match the way your team works. A simple tool may reduce initial friction, while a deeper tool may give estimators more room to manage complexity as the business grows.
| If you choose On-Screen Takeoff | If you choose eTakeoff |
|---|---|
| You get an estimator-centered workflow with structured Conditions, areas, and revision management, AI-assisted measurement through Takeoff BOOST, a native path to Quick Bid for estimating, and training included from day one. But Quick Bid is a separate purchase, and BIM workflows are not supported natively, so teams that rely on 3D model-based takeoff will need to account for that gap. | You get a configurable takeoff tool with assemblies, Excel-based workflows, and strong multi-user support with record locking. If your estimating workflow runs through Sage, Bridge gives you a direct connection. But estimating is not part of the core product, and teams working across multiple devices should factor in reported lags in data syncing, which can create gaps in information. |
Consider the type of work your team does now, and the workflow you expect to manage as project complexity, revision volume, and estimating demands increase.
| Situation | Consider |
|---|---|
| You need a structured, estimator-led workflow for complex plan sets and multi-trade bids | On-Screen Takeoff |

| You want AI-assisted automated measurement across your plan set | On-Screen Takeoff |
| Training and support matter to your team | On-Screen Takeoff |
| You want a connected view from project discovery to completed takeoff to estimating | On-Screen Takeoff |
| You need configurable takeoff with assemblies and Excel-based workflows | eTakeoff |
| Your estimating workflow runs through Sage Estimating | eTakeoff with Bridge |
| Your workflow includes BIM or 3D model-based takeoff | eTakeoff |
| Multiple estimators need to work in the same project at the same time | eTakeoff |
Both products support digital quantity takeoff from construction drawings. On-Screen Takeoff emphasizes structured, estimator-controlled organization across conditions, areas, repeatable layouts, and drawing revisions. eTakeoff emphasizes configurable PDF takeoff with assemblies, formulas, variables, Excel integration, and multi-user capabilities. The right choice depends on your team’s estimating system, project documents, collaboration model, and preferred workflow.
On-Screen Takeoff is the takeoff product. Quick Bid is a separate, optional estimating product that can be evaluated with On-Screen Takeoff when your team wants a connected path from takeoff into estimating. Teams using another estimating system should confirm the available export or integration workflow for that system.
Not as part of the core product. eTakeoff Dimension handles digital takeoff and quantity measurement. To move from takeoff to estimate, teams need eTakeoff Bridge, which connects to Sage Estimating 300, or a separate spreadsheet workflow. On-Screen Takeoff users who also purchase Quick Bid get a native, one-step estimating connection within the ConstructConnect ecosystem.
Takeoff BOOST is ConstructConnect’s AI-assisted measurement add-on built directly into On-Screen Takeoff. It provides a suite of AI tools built for a faster first pass on area, linear, and count conditions. The estimator reviews and refines the results before they go into the bid. It requires an add-on subscription and is part of the broader Takeoff BOOST suite available across ConstructConnect’s takeoff products.
There is no universal answer. On-Screen Takeoff may be a better fit when the team prioritizes structured takeoff organization, multi-condition measurement, repeatable plan workflows, drawing revisions, and estimator-reviewed AI assistance. eTakeoff may be a better fit when the team prioritizes configurable assemblies, Excel-centered workflows, concurrent multi-user access, or Sage Estimating 300 connectivity through Bridge.
