As-Built ROI & Rework Calculator

Connecting your budget to avoided rework

Enter your construction budget and expected rework rate to see what accurate as-builts save on a typical project.

Rework Runs 3 to 9 Percent

Where bad existing-conditions data meets the budget

Industry studies put construction rework at 3 to 9 percent of project cost, with half or more traced to bad existing-conditions data.

Why as-builts fail

What the Calculator Accounts For

Linking exposure, cost and return in one view

Rework exposure, the preventable share, documentation cost, net savings, and the return ratio.

Price the Documentation Side

Carrying the savings against the drawing-set cost

Pair this with the as-built cost estimator to compare savings against the actual drawing-set cost.

As-Built ROI & Rework Calculator

See how quickly accurate documentation pays for itself in avoided rework

What Drives Your As-Built ROIThe four inputs behind the rework calculation
  1. Construction / renovation budgetThe total project spend the rework percentage is applied against — the starting point for every figure in the estimate.
  2. Expected rework rateChoose low (3%), typical (5%), or high for a complex retrofit (9%) — the share of budget that construction rework commonly consumes.
  3. Preventable shareHow much of that rework accurate as-builts can avoid: conservative 50%, typical 60%, or well-coordinated 70%.
  4. Scanning / as-built costWhat the documentation itself costs — subtracted from avoidable rework to give net savings, and divided into it to give the ROI ratio.

Illustrative estimate — not a guarantee. Construction rework commonly runs about 3–9% of project cost, much of it driven by inaccurate or missing existing-condition information. Actual savings depend on project complexity, coordination, and how the model is used.

The Numbers Behind ReworkWhy existing-condition accuracy pays for itself
  • 3–9%Of project cost typically lost to construction rework
  • 50–70%Of that rework preventable with accurate as-builts
  • 5%Typical rework rate used as the default assumption
  • 60%Typical preventable share for a coordinated project

With Accurate As-Builts vs. WithoutWhere the money goes on a renovation
With accurate as-builts
  • Conditions verified before design decisions are locked
  • Clashes found in the model, not in the field
  • Change orders driven by scope, not by surprises
  • Documentation cost known and fixed up front
  • Point cloud reusable on the next phase
Without accurate as-builts
  • Design built on drawings that no longer match the building
  • Conflicts discovered after material is ordered
  • Rework typically 3–9% of total project cost
  • Field delays and schedule slip compound the cost
  • The next project starts from the same guesswork

What the Estimate Accounts ForHow each figure in the result is built
  • Rework exposureYour budget multiplied by the rework rate you selected — the total at risk.
  • Avoidable reworkRework exposure multiplied by the preventable share — what accurate as-builts can realistically recover.
  • Documentation costYour scanning and as-built cost, taken from the cost estimator or your own quote.
  • Net savingsAvoidable rework minus documentation cost — the bottom-line figure.
  • ROI ratioAvoidable rework divided by documentation cost — what each dollar of documentation returns.

How the ROI Is CalculatedFrom project budget to net savings
  1. Project budgetYour total construction or renovation spend.
  2. Rework exposureBudget multiplied by your selected rework rate of 3, 5 or 9 percent.
  3. Avoidable shareExposure multiplied by the 50, 60 or 70 percent you expect to prevent.
  4. Net savings & ROIDocumentation cost subtracted for net savings, and divided into avoidable rework for the ROI ratio.
