Petroleum Building – Chiller and Cooling Tower Replacement

The Petroleum Building, built in 1956, is a 190,000-square-foot, 15-story building located in downtown Denver. This mid-century modernist facility, designed by Denver architect Charles Strong, was Denver’s tallest building at the time.

Hired by Rocky Mountain Trane, 360 Engineering provided prime consulting and mechanical engineering services for the replacement of two 200-ton chillers in the basement, two cooling towers on the roof, and chilled water pumps, with same-capacity equipment. All of this equipment was past its proper functioning lifespan.

360 Engineering worked with structural engineer, Martin/Martin, to determine a pathway for the basement chiller replacements. Additional mechanical and plumbing engineering scope included providing layout and coordination for the new equipment, verifying equipment sizing, and providing piping coordination, details, and drawings for the chilled water system equipment replacement.

I’ve worked with 360 Engineering for nearly a decade. They have been exceptional at listening to our concerns and desires to provide an end product that works best for each situation. From my experience, engineers often believe there is only one way to do business and only one solution to every problem. In reality, the solutions available are vast, and you need an engineer that can identify goals and challenges, evaluate solutions both in terms of viability and cost, and make sure at the end of the day the system that is installed is what you paid for. 360 Engineering exceeds the mark on all fronts.

From in depth initial assessments of systems, to troubleshooting, to caring about the quality and effectiveness of the contractor’s end user trainings, 360 Engineering is a cohesive team player. Denise leads her team by emphasizing “the big picture” and customizes the solutions proposed for each project to suit the particular needs of the building, the occupants and those charged with maintaining the systems. Their common sense approach to engineering, while providing innovative and efficient solutions, has made them our preferred mechanical engineering firm.

The engineers were outstanding in their interest and attention to my concerns during our very productive meeting on location last summer. Our exchanges during that meeting were the best and most productive I have experienced in any of the previous projects I have been involved in. I believe many of our common concerns were resolved in the course of that meeting.

I’ve worked with 360 Engineering on a variety of projects ranging from building assessments to HVAC system upgrades and laboratory renovations.

The majority of my work is on existing buildings and they take the time to understand the existing systems. I can count on them to provide my clients with well thought-out solutions.

I wanted to let you know how impressed I’ve been with the 360 team on Douglas County High School. Joe and Taylor have been great to work with. They’ve made the complex Mechanical and Plumbing scope seem easy – which has taken a lot of weight off my shoulders. As you know, as a prime, having the confidence and trust that your team will handle their business is such a relief!

When the design team came in, our management team at DEVA had changed scope from the design team’s expectations. They had initially planned 17 compressor units in various locations, and the morning we started the VA/CBA process, our DEVA team asked if we would be able to plan based on a chiller / campus-wide HVAC scenario. I watched the excitement start, and the wheels turn, and we were off to the races! Two days later, we had the system designed, at least conceptually. It was a great experience!

I have personally worked with their firm for respective services [professional mechanical engineering] and they have provided a quality level of engineering with the knowledge and experience in the industry. Their team has also been responsive on collaboration and dedicated to achieving the goals required of the projects. I would recommend 360 Engineering, Inc. for prospective needs on Mechanical Engineering design services.
