We deliver high-quality consulting and mechanical engineering services through a thoughtful, collaborative approach grounded in performance and long-term value. Our engineers listen closely, investigate existing conditions, and consider the full context of each project. We evaluate viable system options, clearly explain the benefits and considerations of each, and work with clients and project teams to identify solutions that balance performance, constructability, and cost.
Every project is approached with an energy-efficiency and lifecycle perspective—accounting for maintenance, utility costs, and upfront investment—resulting in right-sized solutions that meet today’s goals while supporting long-term operations and sustainability.
360 Engineering provides mechanical engineering design and engineering consulting services from our headquarters in Golden, Colorado—serving clients throughout the Denver metro area, across Colorado, and nationwide. While many of our projects are in Denver and along the Front Range, we regularly support clients across the United States.
Our central location near major transportation corridors and the Colorado high country allows our team to travel efficiently to projects statewide and beyond. Our engineers are licensed Professional Engineers in more than 45 states, including Colorado, Utah, and Wyoming, and we obtain additional licensure as needed to support projects nationwide.
Our office culture shifts naturally from focused quiet to lively conversation—and occasionally to fast-paced, deadline-driven energy, sometimes all on the same day. While meeting deadlines is essential, we prioritize employee well-being and work to prevent burnout, including a schedule that offers every other Friday off for nine months of the year.
