  1. Materials Certification List Quarterly Design Meeting 02/07

  2. The Materials Certification List (MCL) is a project specific document that allows the designer to direct what materials are used on the project and who approves them. • This is an overview to explain the importance of the MCL throughout the design, construction and project closeout processes.

  3. Sample of completed MCL for various items

  4. Overview • Careful preparation of the MCL benefits the Designer, the Contractor, the Project Engineer, and ultimately, the traveling public. • The MCL ensures that high quality, approved products are easily incorporated into the work.

  5. Vocabulary • MCL – Materials Certification List. The list of material certifications required by the Contract. • MCL Coordinator – Lead Materials Rover, Quality Assurance Section, Construction • QPL – Qualified Products List. Items on this list need no further approval for use on the project. • QA – Quality Assurance Section

  6. MCL Preparation • The project MCL is developed in Design for inclusion in the Pre PS&E assembly. • (The MCL Coordinator will assist first timers in the preparation of the MCL.) • Bridge Design, Traffic and Utilities prepare their portion of the MCL. • QA reviews the MCL. • Comments are addressed in Final PS&E. • A review at Final PS&E can be requested of QA. • We want it right!

  7. Here’s why: • The MCL assists the Designer in controlling the submittal approval process. • The MCL helps the Designer ensure that the planned materials are used. • The MCL assists the Contractor by listing required certifications. • The MCL is used Statewide, so Contractors know what to expect in all regions.

  8. Here’s why, cont’d. • The MCL assists Project Engineers by listing the level of approval for each item, and gives them more latitude in approving materials at the project level, saving time and $$$. • This reduces the work load of the Designer, the Contractor, and the Project Engineer and simplifies project record keeping requirements.

  9. Summary • The benefits of careful preparation of the MCL continue throughout the life of the project. • The MCL reduces guesswork for the Contractor and the Project Engineer, reduces the time spent tracking down certifications, and speeds up the project closeout process. • All of the above reduce project costs, to the benefit of the traveling public.

  10. Where to Get More Information • For questions, contact the MCL Coordinator at 269-0655. • The Master MCL and the QPL can be downloaded from the Statewide Materials Quality Assurance resource webpage: http://www.dot.state.ak.us/stwddes/desmaterials/mat_resource.shtml#waqtc
