The North Base facility was built in 1989 and consists of three connected buildings, the 24/7 39,500 sf operations building, the 36,500 sf vehicle maintenance (VMS) high bay and the garage. The scope of the project was to replace all heating, ventilation and HVAC equipment that serves the operations and vehicle maintenance buildings with more energy efficient options. Workspace was also reconfigured to improve flow and space utilization. The project was designed in phases to facilitate efficient completion of the renovations while maintaining the 24/7 operation of the facility.
In planning this project, stakeholders were adamant about improving occupant comfort with serviceable, maintainable systems. Secondly, they wanted to introduce new technologies to the division’s operations to improve energy efficiency. Lastly, they were intentional in meeting contracting goals, while adopting a new project management approach to streamline decision-making and engaging those with the project intellect to advance the project objectives. Adding to the project complexity was the lack of as-built drawings and the above-the-ceiling system distribution. Part of the strategy to improving energy efficiency was to introduce VRF systems to the building. If successful, the system would become the division’s standard. In summary, this project was going to set a new standard for their approach to system selection and capital planning.
Successful in demonstrating proficiency in the new VRF systems and developing approaches to enhance the project outcome, we were able to introduce additional conservation measures that elevated the project to one of the most energy efficient buildings in Metro’s operations while maintaining the project budget and schedule.
“The consultant’s performance during this project was very good. Technical knowledge of the state-of-the-art, most efficient and cost effective building systems that Hargis’s design team provided to the project team, resulted in one of the most energy efficient bus facilities that Metro operates.
The consultant was responsive, proactive, practical and professional and we have no hesitation to work with Hargis and their team in the future if the opportunity arises.”
