ACI 301 is the reference specification for structural concrete, and a subcontractor that does not read the tolerances, the testing, and the acceptance criteria underprices the quality control.

What ACI 301 sets

ACI 301, Specifications for Structural Concrete, sets the materials, the tolerances, the placement and curing, and the testing and acceptance criteria a project incorporates by reference. A concrete package uses ACI 301 and the Division 03 specifications to set the quality requirements the sub must meet and document.

Why these requirements are easy to miss

The tolerances, the testing frequency, the curing, and the acceptance criteria sit in ACI 301 and the project specifications, not the title. A sub that underreads the testing or tolerance requirements carries the wrong quality control labor into the bid.

How an AI bid agent reads ACI 301

An AI bid agent reads each concrete package, identifies the ACI 301 requirements, and surfaces the tolerances, the testing, and the acceptance criteria that drive the work. The concrete sub prices the actual quality control.

You can see how the agent reads a concrete package in our AI bid agent demo for specialty trade contractors. It pulls the ACI 301 tolerances, testing, and acceptance criteria so the quality control is priced.
