Six years ago, Presbyterian Healthcare Services included a plug-n-play chassis when it built its five-story Presbyterian Rust Medical Center Hospital in Rio Rancho, N.M. The state’s second-largest health care provider adopted the strategy so that, during anticipated expansions, crews could easily link new structural and mechanical systems to existing ones.

The plug-n-play method is facing its biggest test yet with the center’s 200,000-sq-ft fast-tracked addition. Construction of the $80-million facility began in May 2014.
