Development

I build software for construction. Takeoff, estimating, and the tools I wish I had at the bid desk. This is the hub for the code side: products, apps, open source, and the notes I keep while building.

Products

• takeoff.bid ↗: construction takeoff for Mac and the web. Measure plans, link quantities to estimates, and price the job.
• Construction Takeoff videos and guides: AI-assisted measurements, linked estimates, production workdays, and bid comparisons.
• Construction Takeoff for Codex: the plugin and macOS companion for agent-driven takeoffs.
• Hardhat: construction estimating on macOS.
• openmud ↗: AI tools for heavy civil construction. Wiki notes.

Apps

• All apps: 18 iOS and macOS apps on the App Store.
• Construction Takeoff on the Mac App Store ↗
• Cursor Widget for macOS ↗
• Web tools: small utilities that run in the browser.

Code

• GitHub: @masonearl ↗
• construction-takeoff-plugins ↗: open source takeoff plugins.
