Apprenticeship requirements

Design-build and design-bid-build teams will comply with an apprentice utilization requirement. The goal is that 15 percent of project labor hours will be performed by apprentices. The apprenticeship program provides on-the-job training and supportive services to assist contractors with recruitment and placement of minorities and women, as well as to provide advocacy and support for individual apprentices/trainees participating in the program.
