Civils.ai processes construction drawings and documents for quantity takeoffs and issue checks. Contractors and estimators can describe a measurement scope, while engineering and commercial teams can investigate discrepancies across project material. The aim is to produce quantities or findings that can be reviewed against the source documents.
The service brings together two related workflows: extracting what needs to be measured and comparing what different documents say. Its free engineering and estimating calculators are separate resources; their availability does not establish free access to the AI document workflows.
The takeoff workflow begins with PDF drawings and a written description of the required scope. Documented examples include areas, lengths, volumes and item counts across trades such as groundworks, utilities and finishes. Civils.ai describes a QA review stage before delivery, followed by browser review and corrections. Results can be exported to Excel and as annotated PDFs.
The document-checking workflow compares drawings with other sheets, specifications and supplied requirements. Findings can concern inconsistent dimensions, tags, materials or values across disciplines. Citations lead back to the relevant sheet, page or clause so the team can inspect the basis of a flag.
Reviewers can accept, dismiss or escalate findings. Reusable checks help apply a defined list of questions to later tender or contract packs. Contract-document tasks can also extract submission dates, review periods and required deliverables into a checklist.
Assemble the current drawing revision and the specification for one trade package. State the scope in concrete terms, including exclusions and the units required in the output. For a floor-finish package, identify which rooms, surface categories and deductions should be considered before requesting the takeoff.
Review the returned annotations and compare selected measurements with the source sheets. Check that the correct revision, scale and boundaries were used. Correct the quantities in the browser before exporting them into the estimate. Quantities still need the project's rates, waste assumptions and commercial judgment before they become a bid.
Run a separate document check for conflicts between the finish schedule and specification. Open the citations and have the responsible reviewer decide whether a flag requires clarification. A cited difference is evidence to investigate; the contract hierarchy and applicable project requirements determine the resulting action.
The plans page distinguishes paid single-user subscriptions from custom Enterprise access. Takeoff accounting depends on the drawing sheet and its scale, so one uploaded sheet should not automatically be treated as one billing unit. Compare the intended workload, storage and team requirements before selecting access.
Standard document searches and checks are subject to fair use. More involved agent workflows may require separate scoping and pricing. Confirm the workflow being purchased rather than extending a standard search entitlement to every automation.
Vendor QA and source citations support review, but they do not replace the team's acceptance of quantities or a qualified professional's assessment of engineering and compliance issues. Keep the source revision and record of corrections with the exported output so later decisions can be traced.
