A CULTURE OF SAFETY

People are our first priority. Protecting the health and safety of employees and those involved in our projects has always been – and will always be – the most important part of our work. We work smart so we can all go home safe. Our commitment to safety revolves around four directives:

  • Establish Safe Working Environments for All
  • Remember Safety is a Responsibility We Share
  • Encourage Employees to Communicate Concerns
  • Recognize and Reward Safe Work

SUSTAINABILITY

We take our responsibility for protecting the environment seriously. Our commitment to build a better community includes: being resource efficient, minimizing impact on the natural environment, and eliminating unnecessary energy waste from our equipment and operations.

We believe reduce, reuse, and recycle is the best policy. Sunroc diverts millions of tons of construction waste from landfills each year. Asphalt and concrete materials are crushed and filtered to create new aggregate for recycled products, and hundreds of thousands of gallons of oil have been recycled.

Sunroc maintains strict idling and driving standards for all company vehicles and operational machinery, helping us eliminate unnecessary pollutants from our communities.

Recycled concrete and asphalt products are available to all our customers. We make it that much easier for our clients to build sustainably.

Sunroc maintains sustainability standards for offices and jobsites, including a Construction Waste Management plan and a Construction Activity Pollution Prevention plan.
