Bristol Bay Area Health Corporation Dental Clinic and Administrative Offices
RBA Engineers, Inc. provided mechanical and electrical design for this medical facility, located in Southwest Alaska. In lieu of boilers, the heat is obtained from a steam converter, located inside the main Hospital basement mechanical room. A Central Air Handling System and Glycol Heating system were paired to provide comfortable, zoned cooling and heating to the building. Specialized water, waste, and gas piping were designed to accommodate the dental suite. Numerous other design objectives were met with this remote project.

Location of Project: Dillingham, Alaska
RBA Engineers, Inc. provided mechanical and electrical design for this medical facility, located in Southwest Alaska. In lieu of boilers, the heat is obtained from a steam converter, located inside the main Hospital basement mechanical room. The insulated arctic pipe, with heat tape protection, runs between the two buildings. Since the crawl space may have off-gassing from buried waste, RBA engineered a fume exhausting system to maintain negative pressure that discharges above the roof line.
A central air handling system, with remote condensing unit for air-conditioning, furnishes HVAC for the two-story structure. Heated glycol is circulated for heating thru baseboard and cabinet unit heaters, as well as heating coils for zoned temperature control. Additionally, the SCADA system ties into the hospital’s computers to provide a unified system that can be monitored for operation and alarm functions.
The dental chairs have oxygen and nitrous oxide piped to each of nine stations. A vacuum pump is used to evacuate the cuspidors. Clean and dirty linen closets are provided. The entire building is sprinkled and sewer piping was laid out for gravity drainage, without lift pumps.
For the electrical system, RBA designed the 15 kV service transformer and line extension, using underground cabling. The site lighting uses LED lamps that dim in the absence of detected motion. Headbolt heaters for staff vehicles are incorporated. All interior fixtures are high efficiency LED type.
The receptacles have additional ground conductors for added patient safety. All owner-furnished equipment for dental and office use was connected to power panels. Finally, the fire alarm and sprinkler system provide life safety protection for the structure and occupants.
