RAPID CITY REGIONAL HOSPITAL CENTRAL UTILITY PLANT | RAPID CITY, SD 
Skyline Engineering worked with Rapid City Regional Hospital and HDR to develop a new Central Utility Plant to replace the existing plant. The new Central Utility Plant is sized to serve 750,000 square feet of medical facility. It will incorporate state of the art mechanical and electrical equipment and distribution techniques. In addition to maximizing energy efficiency, distribution to the existing facility is addressed through the development of a 600 foot underground utility tunnel. Steam, chilled water, medical gas, domestic water, natural gas and electrical services will be distributed through this tunnel which is actually being installed under the old plant while it remains temporarily in service. Water, gas and electrical services along with underground fuel oil storage tanks are also being relocated or replaced. ($18,000,000 – 2009)
CITY OF RAPID CITY/RAPID CITY AREA SCHOOLS COMMON ENERGY PLANT | RAPID CITY, SD
The Common Energy Plant supplies energy to the Rushmore Plaza Civic Center and Rapid City Central High School (approximately one million square feet of connected load). Retrofit of the chiller and boiler equipment was necessitated by not only the age (most equipment had been in service for over 35 years), but also by capacity issues caused by multiple expansions to both facilities. The new chiller and boiler systems, along with the distribution and controls upgrades, will yield dramatic reductions of operating costs. Full redundancy of a majority of the systems, especially those necessary for heating, along with emergency on-site electric generation, will allow continued energy supply to the facilities served during equipment failure or power outage. Skyline was the prime consultant on this project and developed a construction phasing plan that allowed full retrofit of the plant with no owner downtime and no expansion of the plant footprint. ($6,000,000 – 2013)
