On-the-Job Training Program

On-the-Job Training (OJT) requirements & PAC-UP plan for Prime Contractors


On-the-Job Training (OJT) is a federal program that is required on all Federal-Aid construction projects. CDOT requires its Prime Contractors to provide training aimed at developing full journey workers in a trade or job classification on the awarded project. The minimum number of required training hours is specified in the contract. 

The minimum length and type of training for each skilled craft shall be as established in the Contractor's Training Plan, which outlines the training hours the Contractor will provide to meet or exceed the goal set for the project. Failure to comply with OJT requirements may result in the withholding of progress payments and/or the assessment of damages.

Trainees who work on highway construction projects that are federally assisted in whole or in part, and who are not properly enrolled in an OJT program described, will be deemed journey level workers and must be paid FULL Davis-Bacon wages.

Contractors must submit documentation through LCPtracker (or submit the Form 838 to the Region Civil Rights Office for Local Agency Projects not using LCPtracker).


CDOT issued an updated OJT Specification in August, and it became effective on all contracts advertised after September 6, 2018.

OJT Plan Options

Types of OJT Plans

There are four options for Contractor OJT Plans:

  • CDOT’s pre-approved classifications utilization program (PAC-UP) 
  • A registered U.S. Department of Labor training or apprenticeship program;
  • Approved programs through other groups like Colorado Contractors Association (CCA), Western Colorado Contractors Association (WCCA), and/or workforce centers;
  • CDOT- and FHWA-approved plans specific to the Prime Contractor.

Once a Contractor has identified enrollees and has an approved plan and , they submit CDOT Form 1337 - OJT Contractor Commitment to Meet OJT Requirements at the pre-construction meeting or as soon as possible thereafter to the CDOT Project Engineer. Additional pre-approved training programs and/or additional approved trainees may be used at any point throughout the project. The plan option(s) that the Contractor chooses are effective for the duration of the project.
