What is On-Screen Takeoff?

On-Screen Takeoff is a takeoff and estimating platform with more than 30 years in the construction industry and 40,000+ active licensed users. It supports 20+ construction trade types with advanced measurement tools including Multi-Condition Takeoff (patented), bid areas and zones, Typical Areas, and overlay comparisons for plan revisions and change orders. AI-powered automation is available through Takeoff BOOST™, a full suite of AI tools that can return a full page of takeoff in seconds.

On-Screen Takeoff integrates with ConstructConnect® Project Intelligence (825,000+ active projects), Quick Bid® for professional estimating, and Microsoft Excel®, creating a connected path from project discovery through measurement, estimating, and bid submission.

Best for: General contractors and multi-trade subcontractors who need a proven takeoff and estimating platform across a wide range of trade types, with AI-powered automation and integration to a broader preconstruction workflow.

What is BuzzBID?

BuzzBID is a cloud-based takeoff and estimating platform built specifically for interior finish and specialty trades: drywall, metal framing, acoustical ceilings, fireproofing, plaster, EIFS, insulation, and painting. Its core technology is ClickONCE™ computer vision, which automates takeoffs through single-click and double-click actions that detect and measure walls, ceiling tiles, door assemblies, corner bead, and trim. The Advanced plan includes assembly-based estimating, work breakdown structures, labor modifiers, subcontractor management, and bid proposal generation.

Best for: Specialty subcontractors focused on drywall, interior finish, fireproofing, or wall and ceiling trades who want a purpose-built computer vision workflow with integrated estimating in a single platform.

Feature On-Screen Takeoff BuzzBID Advanced
AI / Automation Approach The Takeoff BOOST suite: Auto Takeoff detects and measures areas, linear dimensions, and counts across your entire project. Also includes Auto Count, Auto Name, and Auto Link. Users report up to 95% time savings vs. manual takeoff. ClickONCE™ computer vision automates takeoffs through single-click detection of wall partitions, ceiling tiles, door assemblies, corner bead, and trim. Designed specifically for interior finish trade geometry.
Trades Supported 20+ trade types: Drywall, Painting, General Contracting, Concrete, Electrical, Mechanical, Roofing, Flooring, Framing, Plumbing, HVAC, Masonry, and more. Drywall, metal framing, acoustical ceilings, fireproofing, plaster, EIFS, insulation, and painting.
Estimating Tools Integrated estimating worksheets and connection to Quick Bid for full estimating and proposal generation.

Trade & Manufacturer Pricing Databases Trade-specific and manufacturer pricing databases available through On-Screen Takeoff and Quick Bid. No trade or manufacturer-specific pricing databases.
Change Orders & Alternates Change orders, bid overlays, and plan revisions are managed within the same project file, so estimators don't have to start from scratch when plans are updated. Change orders and alternates are not supported.
Bid Areas and Zones Yes. Bid areas, zones, and Typical Areas allow estimators to organize complex multi-scope projects and reuse repeated measurements. Not available.
Platform Integrations ConstructConnect Project Intelligence (825,000+ active projects), Quick Bid, and Microsoft Excel. PDF export and Excel export only. No integrations with project data platforms, estimating systems, or subcontractor networks.
Support Phone, email, live webinars, expert-led training, and product documentation through ConstructConnect. Software, updates, support, and unlimited training included with all plans.

Key Differentiators

AI Automation

Both products automate takeoff measurement, and both cover interior finish trades. The difference is in how the AI is built and what it can do beyond that.

BuzzBID’s ClickONCE™ computer vision was designed specifically around interior finish geometry. One click measures a wall partition. A double-click picks up every connected wall segment on the page. Another click counts corner bead across an elevation. That specificity reflects a system trained on drywall, framing, and ceiling drawings. It recognizes the shapes and patterns those trades produce.

On-Screen Takeoff’s Takeoff BOOST automates the same types of measurements, including walls, ceilings, and door assemblies, giving you a head start on your project. It isn’t limited to one trade’s geometry, it applies across all 20+ trade types On-Screen Takeoff supports. A specialty sub estimating drywall and metal framing today and picking up insulation or painting work tomorrow doesn’t need to change tools. A GC estimating team working across multiple trades on the same project runs Takeoff BOOST throughout.

The distinction: BuzzBID’s ClickONCE™ computer vision is purpose-built for interior finish. On-Screen Takeoff’s Takeoff BOOST covers interior finish as part of a broader automation capability that extends to other trades in the same platform.

What Happens After the Takeoff

BuzzBID is a self-contained platform: takeoff and estimating in, PDF or Excel file out. To find the project in the first place, receive the drawings, send invitations to bid, or track submissions, BuzzBID users need separate tools for each step. There are no documented connections to project data platforms, subcontractor networks, or estimating databases.

On-Screen Takeoff is built to connect those steps. Before the takeoff starts, On-Screen Takeoff integrates with ConstructConnect Project Intelligence, where estimators can find and access plans across 825,000+ active commercial projects, so documents flow directly into On-Screen Takeoff rather than being downloaded from elsewhere. After the takeoff, measured quantities move into Quick Bid for detailed estimating with manufacturer pricing databases, and into ConstructConnect Bid Management to send invitations to subs, track responses, and manage submissions. The full workflow, from project discovery through takeoff, estimating, and bid submission, runs through a connected workflow.

What Customers Say About On-Screen Takeoff

Using ConstructConnect's On-Screen Takeoff and Takeoff BOOST, yesterday, I did three projects in 20 minutes. And that probably would have taken me a couple of days if I was doing them all from scratch.
Sherri WinslowLead Estimator, AKS Interior Systems
I consider Takeoff BOOST and OST pretty critical - they're the footer of our foundation. They hold up our estimating department, which is the forefront of our company. We've built a lot of our business with the help of ConstructConnect, OST, and now Takeoff BOOST.
Shane MillsEstimating Manager, Klover Contracting
The Auto Name feature is spectacular - simple, short and sweet. That was a game changer in my opinion. We picked up decent time with that feature alone, and the accuracy of it made it a big win.
Shane MillsEstimating Manager, Klover Contracting
Being able to [use Multi-Condition Takeoff] and do multiple measurements simultaneously is fantastic.
Andrew SkidmoreCost Specialist, Connico
Before using On-Screen Takeoff, my experience was inefficiency.
Andrew SkidmoreCost Specialist, Connico
On-Screen Takeoff to our business in the pre-construction phase of the business is our biggest asset. You could spend a couple days doing an accurate takeoff that you can now do in a matter of hours using On‑Screen Takeoff.
Mike PhillipsVP-Preconstruction, Miller Tippins Construction
I've used this product since 2004. Having done so, I've watched it evolve over the years in a very consistent pattern yet remain very friendly and true to its original interface. And that's given me a great comfort to use... And it’s my best friend.
Richard MillerLead Estimator, American Home Builders
