Using the tools

You may use the current tools to prepare calculations, records and documents for your own work. No subscription or purchase is required. Only enter information you are entitled to handle, and respect the privacy of other people.

Check inputs, units and the tool’s stated assumptions before relying on a result. Cost worksheets use your figures, not verified market rates. Cutting and pallet diagrams do not establish material strength or load safety. Resin volume estimates do not replace the manufacturer’s mixing and handling instructions.

Registers do not verify credentials, insurance coverage, hazard information or legal compliance. Printed inspection and change-order documents are user-created records, not certified evidence or verified electronic signatures. CSV checks cover specific conventions and cannot guarantee that another application will accept a file.

For grants, confirm deadlines, eligibility and application requirements on the official source before acting. A displayed listing or retrieval timestamp is not a funding recommendation or an assurance that an award remains available.

Keep a separate copy of important work. Browser storage, printing and service availability can fail. Features and these terms may change; the review date identifies this version. These terms do not exclude rights that applicable law does not allow to be excluded.
