The UAF CPHR Project was performed by Haskell Corporation Davis Constructors Joint Venture (HDJV).

Located in Climate Zone 8, the $245 million industrial facility provides a coal-fired boiler with a total capacity of up to 240,000 lbs/hr of steam and a steam turbine with controlled extraction ports for providing low-pressure steam to heat campus and produce 17MW of electricity. The circulating fluidized bed (CFB) boiler will be capable of using up to 15 percent biomass in the future. The size of the facility is based on projected campus growth for the next 25 years. It will also connect to the campus electrical system at the campus switchgear building. The facility is approximately 120 feet tall. The circulating fluidized bed technology is more efficient and produces fewer emissions while providing greater output than the current twin stoker boilers.

Preconstruction services were awarded in September 2014.  During that time, it was found that considerable re-scoping was required to accommodate budget constraints as the original project scope could not be achieved within the university’s funding model. The primary scope changes were: Changing from two 140,000 lb/hr boilers to one 240,000 lb/hr boiler, deleting the administration wing, deferring utilidor construction, and relocating the coal unloading facility to the north side of the facility. Babcock & Wilcox Power Generation Group and Shin Nippon Machinery, delivering boiler and the steam turbine respectively as owner furnished contractor installed equipment, assisted in the rescoping efforts.

Overall the HDJV performed approximately 80% of the craft field labor through our craftsman trade groups, including approximately 7,000 l.f of welding on the boiler proper, 2,000 l.f. of pipe welding, and 3,000 l.f. of structural steel welding. Along with placement of approximately 10,000 cyds of structural concrete.
