Schedule of Materials Control
The Schedule of Materials Control outlines the minimum sampling and testing rates required for most materials used in Mn/DOT highway construction. It is inserted into project proposals, and is project specific.
Lab Testing & Inspections Rates
Rates Memo: Mn/DOT performs sampling, testing, & inspections for State, County, City, and other governmentally funded transportation projects. Other governmental agencies are required to reimburse Mn/DOT for this work. This is outlined in the Sampling, Testing, & Inspections Memo. (PDF 20KB 1pp).
Current Rates: (Effective January 10, 2013) for sampling, testing, & inspection are outlined in the Laboratory, Field Testing, and Inspection Rates (PDF 27KB 2pp). Former rates through January 9, 2013 (PDF 19KB 2pp).
IAST Program
Mn/DOT's Schedule of Independent Assurance Sampling and Testing Protocol (IAST) is used by Independent Assurance Personnel on all Federal Aid Construction Projects. The Independent Assurance Program provides a check on testing equipment and procedures for construction projects.
Independent Assurance Inspector Group (IAIG)
Contact the Mn/DOT District Independent Assurance Inspector when project starts to provide the proper servicing of your project.

Materials Lab Testing & Inspection
Lab Testing
Mn/DOT performs laboratory testing of materials for construction and maintenance projects, and research. Mn/DOT Labs consist of ten District labs located in greater Minnesota, and a central facility located in Maplewood, Minnesota. All Mn/DOT labs are certified by AMRL.
Central Office Materials Labs
The central office materials labs perform specialized, as well as routine materials testing in its Maplewood facility. Each individual lab is led by a laboratory supervisor or a lead worker. The aggregate lab, soils & cement lab, and the concrete & metals lab are under the direction of the Physical Testing Engineer, the chemical labs are under the direction of the Chemical Lab Director, the foundation lab is under the direction of the Foundations Engineer, and the Bituminous lab is under the direction of the Bituminous Engineer. Directory of Central Lab Personnel.
District Materials Labs
The eight Mn/DOT districts perform routine project materials testing of bituminous, aggregates, and soils. Each laboratory is led by a laboratory supervisor, or lead worker under the direction of a District Materials Engineer. Directory of District Lab Personnel.
Materials Inspection
Mn/DOT performs inspections of electrical conductors and reinforcement steel, as well as at precast/prestressed concrete plants. Directory of Inspections Personnel.
