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 requires all personnel and laboratories performing materials testing and/or project inspections to be certified. The level of certification is dependent on the specific type of testing to be performed. The Oregon Department of Transportation is a member of the Western Alliance for Quality Transportation Construction (WAQTC), which consists of 11 western states, is committed to the quality of our transportation systems. WAQTC has developed a technician-training program, comprised of instructional and student modules used to assist in the training process of material field-tested procedures. ODOT has adopted the training packages for all material testing certifications except for ODOT specific certifications and those controlled by entities other than WAQTC such as QCT, CCT, CMDT and CAT II. To obtain any of the certifications, the technician/inspector is required to pass a written and/or a practical test demonstrating a knowledge and understanding of how to perform the specific test/inspections. Links to each of the certification websites are available in the left-hand column. These websites will provide additional information regarding the certifications, training registration, and how to challenge the exams. The information below describes each certification. Certified Aggregate Technician (CAgT) or WAQTC equivalent (AgTT): A CAgT performs a variety of tests on soils and aggregates including sieve analysis, fracture, sand equivalency, and other tests. A CAgT also performs other duties as required by current specifications for soils and aggregate materials. Certification duration: Initial - 3 years and recertification - 5 years. 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, and other tests and duties as required by current specifications. Certification duration: Initial - 3 years and recertification - 5 years. 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. Certification duration: Initial and recertification - 3 years. Certified Bridge Construction Inspector (CBCI): The certified bridge inspector is responsible for inspecting the various types and methods of bridge construction demonstrating proper inspection practices. Five year certification. Certified Drilled Shaft Inspector (CDSI): The certified drilled shaft inspector inspects drilled shaft construction using standard -of-the-industry practices including maintaining proper documentation. 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. For soil, soil aggregate mixtures, and aggregates a CDT determines percentages of coarse and fine material, performs one-point testing and related calculations. Certification duration: Initial - 3 years and recertification - 5 years. Certified Embankment and Base Technician (CEBT): The CEBT performs testing of soils and aggregates for establishing the relative maximum density and optimum moisture for use in compaction testing of subgrade soils and aggregate bases A CEBT also determines the Specific Gravities of aggregate. Certification duration: Initial - 3 years and recertification - 5 years. Certified Environmental Construction Inspector (CECI): The certified environmental construction inspector inspects all aspects of environmental work on a project including archaeology, erosion control, hazardous materials, aquatic biology, terrestrial biology, wetlands, planting and seeding, etc. The inspector is aware of NPDES permit requirements and Best Management Practices for environmental disciplines. Five year certification. Certified Erosion and Sediment Control Manager (ESCM): The Erosion and Sediment Control Manager works for the construction contractor and is responsible for the erosion and sediment control features on the construction project. Three year certification. Certified General Inspector (CGI): The certified general inspector is responsible for inspecting a variety of construction projects demonstrating proper inspection practices. The CGI has knowledge of the General Provisions, Contract Administration, and Roles and Responsibilities associated with the project contract. All inspectors should have a general inspector certification as it is the foundation for all other certifications. Five year certification. Certified Hot Mixed Asphalt Concrete Inspector (HMAC): The certified hot mixed asphalt concrete inspector is responsible for ensuring quality HMAC pavement construction. The inspector has knowledge of the paving process and related plans, specifications and special provisions. 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. Certification duration: Initial - 3 years and recertification - 2 years. Certified Traffic Signal Inspector (CTSI): Traffic Signal Inspectors have the knowledge to properly inspect Traffic Signal and Electrical Installations on State Highways. Three year certification. Concrete Control Technician (CCT): A CCT is responsible for proportioning concrete mixtures to meet project requirements and for making adjustments to the mix design as necessary to provide a concrete mixture of the quality required by specifications. A CCT certification may be obtained through a program conducted by OCAPA. Certification duration: Initial and recertification - 3 years 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 ensure 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 the Oregon Chapter of the American Concrete Institute. Certification duration: Initial and recertification - 5 years. 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 American Concrete Institute (ACI) Concrete Field Testing Technician - Grade 1 certification program, with the Oregon written supplement test, conducted by the Oregon Concrete and Aggregate Producers Association (OCAPA). Certification duration: Initial and recertification - 5 years Traffic Control Supervisor/Traffic Control Technician (TCS/TCT): The purpose of a TCS/TCT is to have the knowledge regarding Traffic Control on a construction project. Three year certification. |
