Expansion plans announced Tuesday for Methodist Dallas Medical Center include a six-story trauma and critical care center. The $108 million center will comprise 248,000 square feet and include 58 emergency room beds, six trauma suites, eight surgical suites and a 36-bed critical care unit. The North Oak Cliff hospital also will have the option to add five stories to the new building in the future.

The building is expected to be complete in summer 2014.

Methodist Healthcare System also is expanding Methodist Charlton Medical Center, near Duncanville. That $27.2-million expansion includes 36 new patient care beds, relocating the post-coronary intensive care unit, and adding a specialty care unit. Those projects are expected to be completed in fall 2012.
