Since 1984, our focus has been on providing our clients with a trusted partner they can count on to safely and efficiently build high-quality facilities. In a time when cost and schedule often dictate how buildings are constructed, we do not sacrifice the health and safety of our employees, partners, or clients just to meet a deadline. We take safety to heart and expect everyone on our project site to do the same.

Our mission is the prevention of injury, illness, environmental impact, and property damage during all construction activities, and is accomplished through a tiered approach, including the following:
  • Strong affiliation between JMC, the construction community, and other trades
  • Corporate safety program and project-specific safety plans
  • Enforcement of responsibility and accountability for safety on site
  • Safety monitoring and continuous improvement program
  • Development and enhancement of training for specific construction tasks
  • Injury prevention through focus on activity pre-task planning
  • Procedures to assess the safety program and make any necessary modifications
  • Strong open lines of communication, enabling employees and trades to share thoughts and ideas for improving safety


JMC's safety performance has been recognized by the Associated Builders & Contractors (ABC) with the receipt of 28 awards, including 8 Diamond Safety Training Evaluation Process (STEP) awards. The Diamond STEP is the highest level attainable, and recognizes the elite among contractor safety programs.
