About this file
This document is an appendix detailing Colorado Apprenticeship Contribution Rates effective July 2026 for the 7th Street Garage Repairs project in Colorado. The file establishes standardized apprenticeship wage contribution rates across multiple trade unions and local unions operating within Colorado and specific geographic regions. The rates apply to various construction trades including electrical workers, plumbers, pipefitters, carpenters, roofers, ironworkers, laborers, and numerous other skilled trades. Geographic regions are defined by county designations, with some trades distinguishing between northern and southern Colorado counties, western Colorado, Denver and northern Colorado, and southern Colorado regions. Apprenticeship rates vary significantly by trade and geographic location, ranging from $0.15 per hour for roofers to $1.90 per hour for sprinkler fitters in their fourth year.
Contribution rates are specified as per-hour amounts, with many trades providing differentiated rates based on work classification such as commercial, residential, industrial, or service work. For example, the International Brotherhood of Electrical Workers offers different rates for commercial versus residential work depending on the local union and region, while sprinkler fitters have tiered rates progressing through apprenticeship years to journeyman status. The document provides a comprehensive reference table listing all applicable unions and their corresponding apprenticeship contribution obligations, enabling contractors and public agencies to accurately calculate labor cost requirements for apprenticeship program participation on the 7th Street Garage Repairs project.
