1Build Com — Developer Tools

What is 1Build Com?

1Build Com is a modern API that provides instant access to live construction cost data. It tracks 68 million materials, labor, equipment, and assemblies costs for every county in the United States, making it the only API for live construction cost data.

Problem it solves

Construction software builders and estimators spend hours manually looking up costs that may be outdated or regional. 1Build Com eliminates this by offering a single line of code integration, delivering a beautiful catalog of construction data in real time.

Who it is for

1Build Com is designed for software developers and SaaS companies building construction estimating, project management, or procurement tools. It's also valuable for professional estimators needing accurate, up-to-date cost data. It is not for those who need simple one-off estimates without a technical integration.

Real use cases

Use 1Build Com to enrich your application with live costs for materials like 2X4 lumber at $0.73 per linear foot, drywall at $0.47 per square foot, or equipment rentals like scissor lifts at $185 per day. It covers 25,000+ unique items and assemblies across all CSI divisions, perfect for building takeoff tools or budgeting apps.
