Structure Materials Suppliers - What’s good or bad? Pre- qualification – Can there be more? QC/QA Paperwork - Shortage of Materials and Suppliers
What is good or bad as a supplier for Caltrans? Is payment timely? Are specifications consistent? Would additional material indexing on long-duration projects reduce risk and cost? Have new specifications impacted suppliers?
Pre qualification What procedures should be pre-qualified? CIDH, Welding, Yellow Paint Removal? What materials should be pre-qualified? Concrete, asphalt, rock, cure? What plants/shops should be pre-qualified? Sign structure fabrication, pipe pile, light and signal poles?
QC/QA Paperwork Caltrans is moving toward the contractor being responsible for quality assurance. Caltrans is moving away from method specifications and moving toward performance specifications.
“Tagging” QC/QA Paperwork Caltrans materials release process Timing Transfer Between Projects Certificate of compliance to allow acceptance on site
QC/QA Paperwork Are requirements clear? Is there too much paperwork required? Is the ownership of the acceptance clear? Which materials or operations do contractors want to provide QA?
Shortage of materials and suppliers Why? Because Caltrans is not the owner of choice? Because the volume of work available nears the maximum capacity of suppliers? Limitations on raw material?
WHAT ARE THE ISSUES? Late payment Late material delivery Incorrect QA/QC paperwork Acceptance concerns
