Is Scan to CAD Worth It? A Cost-Benefit Breakdown

For most architects, designers, and construction pros, the question isn’t whether accurate as-built documentation matters. It’s whether paying for a service to produce it is actually worth it compared to doing it yourself. 

Here’s an honest breakdown comparing Twindo Scan to CAD to hand measuring and modeling costs.

What You Can Expect to Pay with Twindo

Let’s use a 1,500 square foot residential project as an example.

Scanning is free in Twindo. You pay when you order a CAD or BIM as-built, and the cost is primarily based on the square footage of the space and file type. See current pricing here.

Your 1,500 square foot residential renovation runs about $390 for a 3D SketchUp file.

What You’d Pay to Do It Yourself

The seemingly more affordable alternative to Scan to CAD is hand measuring and manual modeling. But, many professionals don’t take into account the value of their time when calculating the costs. When doing it yourself, the process looks something like this:

• Travel to the site
• Measure every room and sketch the layout
• Return to the office
• Build the space from scratch in your CAD/BIM software
• Go back to the site when a dimension doesn’t add up

For a 1,500 square foot home, that’s typically two to four hours on site and another four to eight hours of modeling time, depending on the level of detail of your as-builts, your design software, and how many times you have to check a dimension you missed.

At $100 per hour, that’s $600 to $1,200 worth of time on a single documentation task, and $100 is on the conservative end. For a more senior professional, principal, or firm owner, the opportunity cost of spending a day on documentation is considerably higher.

At $390, Twindo is a fraction of that cost, and it frees up those hours for billable design work.

“It saves me about eight hours per project,” says Nicole Gurney of Quality Design and Remodel. “What used to take a full day of measuring and modeling is now a simple scan.”

The Hidden Costs of the Old Way

Time and billing rate are the obvious variables. A few others worth factoring in:

• Errors downstream. An inaccurate as-built doesn’t just waste the time it took to produce. It can cascade into delayed design decisions, contractor bids, and fabrication work. The cost of a measurement error discovered during installation is almost always higher than the cost of getting accurate documentation up front.
• Capacity constraints. If your team is spending four to eight hours per project on documentation, that’s a hard ceiling on how many projects you can take on. 
• Return trips. If you miss a measurement or a dimension doesn’t add up when you’re back at the office, you’re going back to the site. 

“It saves us a lot of time running back to the job site,” says Allison Schmidt of The Cutting Edge Cabinetry. Every return visit is travel time, opportunity cost, and a delay to the project schedule.

When Scan to CAD Workflows Are Worth It

Scan to CAD pays off most clearly when:

• The space is complex enough that hand measuring is slow and error-prone
• Your time has a meaningful billing rate or opportunity cost
• Accurate documentation is required before design work can begin
• You’re working in multiple spaces and the time savings compound across projects

When Scan to CAD Might Not Be Worth It

If you have a simple rectangular room and a low requirement for detail, Twindo Scan to CAD may be more than what you need. But, if you’ve got complex angles and alcoves, or a need to model details like electrical outlets and switches, Scan to CAD will save you time and frustration.

Scan to CAD is also not the right fit for precision fabrication work that requires sub-millimeter tolerances. For those applications, the 1 to 2% accuracy range may not be sufficient, and manually verified dimensions will be necessary.

The Bottom Line

For most architects, designers, and construction pros doing renovation, remodeling, or existing-conditions work on a regular basis, Scan to CAD pays for itself in time savings alone, usually on the first project.
