In early 2021, the State of California will be mandating that all required Mechanical Acceptance Tests be performed by ONLY certified Mechanical Acceptance Test Technicians working for certified Mechanical Acceptance Test Employers. To meet these needs the Bay Area Training Centers will be conducting the required classes for the certification process. For Sheet Metal Journeypersons that do not hold a current TABB Technician certification, the MATT Level 1 certification is available through NEMIC (The National Energy Management Institute Committee, a national Joint Labor Management Committee) and offered through the training centers. There are two classes required, a lecture based class and a hands on lab class. The lecture class will cover State of California code and program requirements, the California Non Residential Compliance Manual and the required Mechanical acceptance test form requirements for each of the nine covered tests that MATT Level 1 technicians are allowed to perform. The Lab class will allow you to perform actual testing for each of the nine covered test forms and will include the required testing sessions for certification.

Two separate MATT Level 1 Lecture classes will be offered with dates to be announced soon. Class A will be scheduled to attend on Monday & Wednesday evenings and Class B attending Tuesdays & Thursday evenings.   Due to current COVID-19 conditions and restrictions, all classes will currently be offered via Distance Learning format using Zoom Video Conferencing. The Hands on Lab classes will be scheduled to start at the conclusion of the final lecture class as an open lab concept.

This is a critically needed certification that can lead to excellent employment opportunities and job hours. In addition, Local 104 is offering a $500 bonus to those Journeypersons who achieve a MATT Certification.

Please contact your local JATC for enrollment information.


Revit 2021 for Sheet Metal Detailing – Online

New Fall Schedule Out Soon!!!

Prerequisite: Basic computer skills, Windows format

This class is a 12-week, 3 hour a week, fully online class that covers how to draw with Revit tools, an exploration of settings that make Revit function, Revit organization & View control. It is designed to give you the information that is important to understand so you will be able to use Revit for detailing with Fabrication duct. The focus of this class is on Revit only, not how to draw ductwork in Revit. Revit is a very sophisticated program that can really make it easier to detail, once you have a good understanding of how it works. This class will give you a good foundation to work from.
