ONLINE COURSE
\nPROGRAM DETAILS
\;The CRMCA is pleased to offer the NRMCA NCDOT/SCDOT Plant Inspector Certification Course on our ONLINE Platform during COVID19
\n
\nPlease register by May 31\, 2020 to ensure mailed delivery of course materials. \; The in person course is 4 hours - for the virtual \;offering we will break it up in to 2 blocks 9am-11am and then 12pm-2pm. \; Once you register we will then send you the video and call in options. \; The session will be presented by live instructors via the GoToMeeting Platform. \; Students will need internet access to fully participate as well as computer with video capability and audio (audio can be via phone if needed).
\n \;
To be approved to inspect concrete plants to supply concrete to either NCDOT or SCDOT projects\, the Inspecting Engineer and the Inspecting Engineer&rsquo\;s Assistant must both take this course \;and pass an exam. In addition\, the Inspecting Engineer must be a registered Professional Engineer in the state that the concrete plant is located. The course covers\, in detail\, each of the items to be inspected during a ready mixed concrete production facilities audit. An actual concrete plant audit walkthrough is included as part of the course.
\n \;
In addition to fulfilling the NCDOT/SCDOT requirements for Inspecting Engineers and their Assistants\, this class offers an excellent opportunity for ready mix producers to familiarize themselves with the details of the NRMCA inspection process. After completion of this class\, producer personnel should be able to perform a "\;self inspection"\; of their plant and institute any corrective measures necessary to bring the plant up to the required standards for NRMCA certification prior to the "\;official"\; inspection. \;Ready mix producer attendees have the option of either 1) electing to take the \;exam \;and (upon successfully passing the exam) become \;either a certified Inspecting Engineer or Inspecting Engineer'\;s Assistant or 2) electing to not take the exam and attend the course for information only.
\n \;
Concrete suppliers included on the qualified product list must also meet all NC/SC DOT specifications and requirements for the equipment\, materials\, and procedures used during the production of concrete.
\n \;
NC/SC DOT personnel have the authority to perform quality assurance inspections of the plants furnishing concrete for NC/SC DOT work at any time without notice.
\n\nPlants that do not comply with NC/SC DOT standard specifications and/or the NRMCA certification program requirements at the time of the NC/SC DOT inspection or that are not furnishing concrete for NC/SC DOT projects may be taken off the approval sheet. Sufficient time for corrections may be allowed for minor violations and a follow-up inspection performed by NC/SC DOT. If such a follow-up is performed\, NC/SC DOT may charge a fee to recover costs for the follow-up inspection. If the NC/SC DOT removes a concrete supplier from the approval sheet\, the concrete supplier must provide a new NRMCA certification along with the inspector documentation to be considered for reinstatement to the list.
