Quality Assurance Certification Program
To find a Technician or Inspector, click the first letter of the last name:
The Oregon Department of Transportation (ODOT) has established a strategy for quality control and quality assurance in its dealings with construction of transportation facilities. The Oregon Department of Transportation’s Quality Assurance program will require all personnel and laboratories performing materials testing and/or project inspections to be certified.
To obtain any of the certifications, the technician/inspector will be required to pass a written and/or a practical test demonstrating a knowledge and understanding of how to perform the specific tests/inspections.
Links to each of the certification websites are available in the left-hand column. These websites will provide additional information regarding the certifications, registering for training, and how to challenge the exams. The information below describes each certification:
Definitions of Terms
Certified Aggregate Technician (CAgT):
A CAgT performs a variety of tests on soils and aggregates including sieve analysis, fracture, sand equivalency, and other tests and performs other duties as required by current specifications for soils and aggregate materials. Three year certification.
Certified Asphalt Technician I (CAT-I):
A CAT-I performs sampling and testing for HMAC and EAC mixtures including AC content, maximum specific gravity, sieve analysis, void measurements using a currently approved compaction device, and other tests and performs other duties as required by current specifications for HMAC. Three year certification.
Certified Asphalt Technician II (CAT-II):
A CAT-II is responsible for managing the volumetric properties of asphalt mixes by controlling plant operations, for troubleshooting HMAC sampling and testing processes, and for making appropriate adjustments to HMAC production and laydown procedures. Certification at CAT-II level is contingent on having successfully completed the CAT-I certification phase at least once. Three year certification.
Certified Bridge Construction Inspector (CBCI):
Bridge Inspection Training will inform the Inspector of the various types and methods of bridge construction and proper Inspection practice. Five year certification.
Certified Embankment and Base Technician (CEBT):
The CEBT performs testing of soils and aggregates for establishing maximum density and optimum moisture for compaction of subgrade soils and aggregate bases. Three year certification.
Certified Erosion Control Inspector (CECI):
The purpose of this class is to inform Inspector's of NPDES permit requirements and Best Management Practices for Erosion and Sediment Control. Five year certification.
Certified Density Technician (CDT):
A CDT performs in-place density testing of soils, aggregates, and asphalt mixtures using the nuclear density gauge. In addition to certification, a CDT must possess a current Radiation Safety Card issued by an approved source. Three year certification.
Certified Drilled Shaft Inspector (CDSI):
The goal of this course is to provide Drilled Shaft Foundation Inspectors with the practical knowledge and Standard-of-the-Industry practices for the inspection of drilled shaft foundation construction. Five year certification.
Certified General Inspector (CGI):
The General Inspector Training is intended to be a pre-requisite for the other specialty certifications. The training will focus on the General Provisions, Contract Administration, Roles and Responsibilities, etc. Five year certification.
Certified Hot Mixed Asphalt Concrete Inspector (HMAC):
The purpose of the HMAC Inspector class is to provide each participant with information and tools to be an effective HMAC Inspector. Attention is focused on items that can be inspected that are critical to the performance of HMAC and necessary for fulfilling contract documentation requirements. Five year certification.
Certified Mix Design Technician (CMDT):
A CMDT is responsible for preparing HMAC and EAC Mix Designs, including all material testing and data analysis necessary to properly complete a design. A CMDT prepares designs for both dense and open graded HMAC mixtures. Three year certification; two year recertifications.
Certified Traffic Signal Inspector (CTSI):
Traffic Signal Inspection training is designed to provide the training and resources necessary to properly inspect Traffic Signal and Electrical Installations on State Highways. The training focuses on Traffic Signals, but applies to all Electrical Installations. Three year certification.
Concrete Control Technician (CCT):
A CCT is responsible for proportioning concrete mixtures to meet job requirements and for making adjustments to the mix design and mix production as necessary to provide a concrete mixture of the quality required by specifications. A CCT certification may be obtained through a program conducted through Oregon Concrete and Aggregate Producers Association (OCAPA). Three year certification.
Concrete Strength Testing Technician (CSTT):
A CSTT is responsible for testing the compressive or flexural strength of hardened concrete cylinders or beams. The duties of a CSTT include proper capping of specimens (bonded and unbonded), correct operation of breaking device and visual evaluation of broken specimens. Also, the CSTT is responsible to insure the proper handling, mold removal, logging and curing of field fabricated samples upon arrival at the laboratory. A CSTT certification may be obtained through a program conducted by ACI. Five year certification.
Quality Control Technician (QCT):
A QCT performs testing of fresh Portland cement concrete including sampling, concrete temperature, slump, unit weight, air content, and fabrication of specimens for strength testing and performs other duties including calculating cement content and water-cement ratio as required by specifications. QCT certification may be obtained through the ACI certification program, with Oregon Supplement, conducted through OCAPA. Five year certification.
