Land Takeoffs for Claude and ChatGPT

Sitework takeoffs from your plans, inside the AI assistant you already use.

Connect Land Takeoffs, send a civil plan set or CAD file, and get quantities back with the sheet or file each one came from. Then download the Excel bid sheet and PDF summary.

What it does

Plan set takeoff

Reads a stamped civil plan set PDF and returns erosion control, clearing, earthwork, storm, sewer, water, paving and concrete quantities by sheet.

CAD earthwork

Measures cut and fill from existing and proposed surfaces in DWG, DXF or LandXML files. It asks you when a surface or boundary is unclear.

Bid-ready files

Every finished takeoff produces an Excel bid sheet and a PDF summary you can download, share or re-open from your account.

Land Takeoffs reports what the plans show and lists anything it could not determine. It does not guess quantities that are not on the drawings. Review results before you bid, as you would any takeoff.

Connect

You need a Land Takeoffs account. If you don't have one, the sign-in screen creates one with Google, Microsoft or email, and new accounts include 1 free takeoff.

Server URL

For custom connectors and other MCP clients:

https://mcp.landtakeoffs.com/mcp

Sign-in uses OAuth. Developers can also use an API key from the account page as a Bearer token.

To disconnect, remove Land Takeoffs in your assistant's connector settings, or revoke it under Connected apps on your account page.

Sending your files

Full civil sets are often 50 to 500 MB, which is more than chat attachments handle well. Land Takeoffs gives you 3 ways to send them, and none of them has a size problem.

A share link. Paste a link from Dropbox, Google Drive or OneDrive set so anyone with the link can view, or a direct download link from your own file server. Land Takeoffs downloads that one file in the background.
A private upload link. Ask for an upload link. The assistant gives you a page where you drop files from your computer. The link works once and expires after 24 hours.
Your account page. Upload at landtakeoffs.com/gradingiq, then ask the assistant about the takeoff.

You can send a plan set and a CAD file together. They become one takeoff: quantities from the plans and measured cut and fill from the CAD.

Example prompts

Run a sitework takeoff on this plan set: https://www.dropbox.com/s/...

I have the civil set and the grading DWG on my computer. Give me an upload link and run a combined takeoff.

How much cut and fill is on this site, and is it balanced?

List the storm pipe by size with the sheet each run is on.

Give me the Excel bid sheet and the PDF summary for my last takeoff.

Show my recent takeoffs and how many credits I have left.

A plan set takeoff usually finishes in a few minutes. Large sets take longer. The assistant checks progress and tells you when it's done.

Tools

These are the actions your assistant can take. "Reads only" tools never change anything in your account.

`start_cad_takeoff`	Starts a measured earthwork takeoff from CAD or terrain files. Uses a credit.	Starts work
`answer_cad_question`	Sends your answer when a CAD takeoff asks which surface or boundary to use.	Updates a takeoff

Credits

Takeoffs use prepaid credits from your Land Takeoffs account. A CAD takeoff uses 1 credit. A plan set uses 1 credit per 100 pages. A takeoff that fails is not charged. You buy credits on your account page, never inside the chat.

Privacy and security

Your assistant only gets access after you sign in and approve it. Access tokens last 1 hour and renew for up to 60 days unless you revoke them.
When you share a link, Land Takeoffs downloads that file only. It cannot see anything else in your storage account.
Files and reports are stored in the United States. Download links expire after 1 hour.
Land Takeoffs does not read your chats. It only receives what the assistant sends to a tool, such as a file link or a takeoff ID.
You can delete any project from your account page. That permanently removes its files, results and reports.

Full details are in our Privacy Policy.

Support

Email support@landtakeoffs.com with the takeoff ID or project name if you have one.

Common fixes:

"The link is private." Change the share setting to anyone with the link can view, or ask for an upload link instead.
"Not enough credits." Add credits on your account page, then ask the assistant to try again.
Sign-in loops or fails. Disconnect Land Takeoffs in your assistant's settings and connect again.
