iSqFt vs ConstructConnect: what is the difference?
iSqFt is now part of ConstructConnect. Here is what each name refers to today, what the combined product does, and what to weigh if you're deciding whether to stay on it.
The confusion is understandable. iSqFt was a well known online plan room for GCs, and a lot of estimators still call the product by that name out of habit. So people search "iSqFt vs ConstructConnect" expecting a comparison of two products, and there isn't one to make.
This sorts out the names first, then gets to the question people actually care about, which is whether the bundle is worth what you're paying for it. Descriptions come from ConstructConnect's own website and press releases as of September 2026. Confirm the details with the vendor before you decide anything.
The short history
iSqFt started as an online bid management and plan room service for general contractors. In May 2016, iSqFt, BidClerk, CMD (the construction data business) and Construction Data Company were brought together under one new brand, ConstructConnect, and iSqFt became a product inside it. In 2018 ConstructConnect bought SmartBid, another bid management tool, and combined it with iSqFt. Today ConstructConnect sells this as ConstructConnect Bid Management. Depending on how old the web page you're reading is, you'll see references to iSqFt, SmartBid, or ConstructConnect Bid Management, and they mostly mean the same thing now.
So there's no iSqFt-versus-ConstructConnect decision. There's a ConstructConnect decision, and iSqFt is one piece of it.
What ConstructConnect sells today
Three things, roughly, and usually bundled.
The first is project intelligence, meaning leads: who is building what, where, and when it goes to bid. This is the data business that came from CMD and BidClerk, and for a lot of subscribers it's the main reason they pay at all.
The second is bid management, the iSqFt and SmartBid lineage. Post a project, distribute plans, invite subs from your own list or from a network ConstructConnect puts at 450,000+ construction professionals, and prequalify bidders.
The third is takeoff and estimating: PlanSwift, On-Screen Takeoff and Quick Bid.
Who the bundle suits
GCs who genuinely use the lead data to find work. GCs who bid in several regions and lean on the network to find subs there. Teams who want plan distribution, invitations and takeoff from one vendor and are happy to pay for the convenience of that.
Where it chafes
The questions worth asking are mostly about the bidding side, not the data.
Subs view invitations and submit bids through ConstructConnect's platform rather than replying to an email from you. Some subs are fine with that. Small local trades are often less keen on a platform they don't recognise. And if the bundle includes lead data for regions you don't build in, you're paying for it anyway.
That's a useful clue about where to look.
Three ways to go from here
Stay, and use the bundle
If you use leads, bidding and takeoff every week, the bundle is reasonable and you should keep it. Do ask for a usage report before renewal, though, so you know that "every week" is actually true and not just what it felt like in the demo.
Keep the leads, change the bidding
Project intelligence and bid invitations don't have to come from the same vendor. A GC who values the data can keep a leaner ConstructConnect data plan and send invitations with something built for that. In our view the best option here is Invite All: it sends one tracked invitation per person from your own Microsoft 365 or Google Workspace mailbox, gives each sub a private link with the drawings and Bidding / Maybe / Not bidding buttons with no account, and shows delivered, clicked, viewed and answered per contact. It doesn't do leads, so it sits beside a data subscription rather than fighting with it. Other options for this route are BuildingConnected (large network, quoted pricing), Pantera Tools (white-label plan room), or an Outlook mail merge with a tracking spreadsheet.
Leave for a full platform
If what you actually want is bidding integrated with project management, that's a Procore or Autodesk Construction Cloud conversation, and honestly the bidding module should be a minor factor in it. Procore's pricing model, explained.
Comparison
| Leads | Sends from your mailbox | Sub account required | Response tracking | |
|---|---|---|---|---|
| Invite All | No | Yes | No | Per contact |
| ConstructConnect | Yes | No | No subscription needed | Opens and downloads |
| BuildingConnected | No | No | Yes (free) | Views and bid intent |
| Procore | No | No | Recommended | Bid intent and activity |
How to evaluate without losing a month to it
Export your trade list from ConstructConnect first, before anything else. You'll need it whatever you decide, and you'll learn a lot about how clean it is. (What to do if it isn't.)
Count real usage for the last quarter: projects posted, invitations sent, leads pursued. Real numbers, not impressions.
Ask three subs what they think of your invitations. One large, one medium, one small. The small one's answer is usually the most informative.
On any demo, insist on seeing three things: the email a sub receives with the From line visible, an addendum sent to everyone still bidding on one scope, and a live list of who hasn't opened an invitation. If a vendor can't show you those in a demo they won't be able to show you on bid day either.
Then, and only then, talk about price.
iSqFt was a good product. ConstructConnect is a data company that also does bidding. Decide based on which of those two things you're actually using.
