Use annotation language buyers search for
Some teams call it markup, others call it annotation or redlining. ContractorCounter supports the same practical review work on construction PDFs.
PDF annotation tool
Construction PDF Annotation Tool
Annotate construction PDFs with the information contractors need to move work forward: comments, callouts, scale-aware measurements, counts, and export-ready markups.
Drawing Review
PDF plan set
PDF comments
Callouts and arrows
Stamps and symbols
Measurement context
Keep comments tied to drawings
Notes make more sense when they stay connected to the exact drawing location, measurement, and count that caused the question.
Prepare clearer handoffs
Export annotated PDFs so review decisions can move into field, estimating, or client conversations with context intact.
Common Questions
Short answers for contractors comparing markup, annotation, measurement, and review tools.
Is PDF annotation different from markup?
In construction search terms they usually describe the same job: adding notes, symbols, measurements, and review context to a drawing PDF.
Is ContractorCounter only for estimating?
ContractorCounter is focused on drawing markup, PDF annotation, calibrated measurement, counts, stamps, comments, and clean exports. Estimating can happen after the markup work is clear.
Does it work in the browser?
Yes. Contractors can open construction drawings, add markups, measure, count, and export without installing desktop-only PDF software.
