Sec 106 establishes the respective obligations of contractor and MoDOT concerning materials to be used.

While most of Sec 106 concerns responsibilities of Construction and Materials, the resident engineer must be aware of its provisions. As MoDOT's representative on the project, the resident engineer must see that all project procedures are in harmony with specifications. No materials should be used for which the resident engineer does not have approval. Specific requirements for inspection and testing are found in the Engineering Policy Guide.

This article presents guidelines for Construction and Materials functions, including information from the former Construction and Materials Manual, Volumes 1-3.

For field inspection guidance, refer to “Construction Inspection Guidelines” articles in the EPG for the specific spec number desired (for example, EPG 200.1 Construction Inspection Guidance for Grading and Removals). Additional field inspection guidelines are located in the EPG 1100 Maintenance Materials group of articles, such as EPG 1106 Carbide-Tipped Snowplow Blades.

Laboratory testing guidelines, like the field inspection guidelines, are located in “Laboratory Testing Guidelines” articles for the specific spec number desired. For example, EPG 1020.8 Laboratory Testing Guidelines for Sec 1020 pertains to sampling metallic-coated steel culvert metal. Additional laboratory testing guidelines are located in the EPG 1100 Maintenance Materials group of articles, such as EPG 1124.4 Laboratory Testing Guidelines.

The Automation Guide is available through EPG Automation Section.

Payment documentation is available at EPG 109 Measurement and Payment.

MoDOT’s Test Methods are located at EPG 106.3.2 Material Inspection Test Methods.

MoDOT's pre-qualified or pre-established lists are located at EPG 106.1 Source of Supply and Quality Requirements. Guidance for pre-acceptance lists (PAL) and the PAL Inspection Guide is available at EPG 106.12 Pre-Acceptance Lists (PAL). New product evaluation information and forms are located at EPG 106.17 New Product Evaluation.

The Technician Certification Program includes a wide variety of information from how to become certified, to certification manuals to math topics.

The General Sections of the former Construction and Materials Manual are also available, including safety, plant inspections, sampling, internal records, certifications, summary of materials inspected, guideline revisions, Pipe Shipping Report Form, special designs and purchase order items.

Inspection guidelines for the Missouri Logo Sign Program, formerly included in the former Construction and Materials Manual, is available.
