Arlington-based Ascension Group Architects’ design-and-build project to replace Portneuf Medical Center in Pocatello, Idaho, was named the state’s top private construction project in 2009 by Idaho Business Review. Sixty-four commercial projects were honored by the weekly business journal, including 19 other private projects.

The roughly $100-million Portneuf project broke ground in June 2009. Plans call for the construction of an addition on the east campus of the medical center and interior renovations throughout Portneuf’s existing facility. Construction is slated for completion in mid-2011.
