Key Compliance Resources for Contractors Working on Public Projects in California
Contractors who plan to work on public works or government-funded construction projects in California need to understand that compliance requirements go far beyond submitting a competitive bid. Two essential resources provided by the State of California help contractors understand their responsibilities regarding labor compliance and workplace safety.
Below are two important references every contractor should review before performing work on public projects.
1. Workplace Posting Requirements (DIR)
The California Department of Industrial Relations maintains a centralized list of required workplace notices that employers must display for employees.

These postings inform employees about their rights, protections, and working conditions under California labor law. Employers must display these notices in a visible location where employees can easily read them during the workday.
Examples of required postings may include notices related to:
minimum wage laws
workers’ compensation rights
paid sick leave
whistleblower protections
workplace discrimination protections
occupational safety information
For contractors working on public works projects, proper posting of these notices is part of maintaining compliance with California labor regulations. Labor enforcement agencies may verify that required notices are properly displayed during inspections or audits.
Failure to maintain required workplace postings can result in penalties or compliance issues.
2. Caltrans Code of Safe Operating Practices (CSOP)
Another important document for contractors working on transportation infrastructure or related maintenance work is the Caltrans Code of Safe Operating Practices (CSOP).

This document establishes the safety procedures used by the California Department of Transportation to guide safe work practices for employees and contractors.
The CSOP manual covers topics such as:
job hazard identification
safe operation of equipment and tools
use of personal protective equipment (PPE)
work zone safety
supervisor responsibilities
incident prevention practices
The manual emphasizes that safety procedures should be reviewed before starting new tasks and periodically throughout the project to ensure workers remain aware of potential hazards.
For contractors performing work on transportation infrastructure or maintenance contracts, understanding these safety expectations is critical.
