This building will provide healthcare needs to the people of the Baltimore area as well as additional visiting patients. Medical institutions are shaped for function rather then aesthetics. The rigid geometric shape of the hospital allows for a new adult emergency, pediatric emergency and fast track departments on the first level with a nurse’s station in the center of each. The new patient tower allows for 291 private patient rooms each with a window, private bath and ample space for visitors. The entrance lobby is an inviting three-story open atrium space.

The exterior façade of the addition will resemble the façade of the existing hospital. Portland cement stucco, red face brick and precast concrete cladding units are assembled to create the matching façade. A curtain wall system composed of aluminum framing and argon filled PPG Solarban 80 insulating spandrel tempered glass is used throughout the first level and entryways. Roof construction will consist of two types of roofing. EP single-ply membrane roofing that includes a non-traffic-bearing sheet membrane system intended for weather exposure as primary roofing used on the new patient tower and entry canopies. The remaining rooftop area is covered by a modified bitumen roofing system. This system consists of two plies of type IV fiberglass felts installed in type III asphalt and coated in one ply of mineral surfaced, Class A fire rated, SBS/SIS modified cap sheet that solidly bonds to the underlying plies when heat is applied by torch, to insure a solid bond. |

Not LEED Certified but there is post-design consideration for certification. Patient care was a higher concern when designing this medical center therefore the importance of facility sustainability has been sacrificed at times. |
