Mission Hospital
New Acute Care Tower

This $43 million tower includes revision of work volume for an 90,000 square foot acute care tower that includes 28 medical/surgical beds, 40 ICU beds (20 per floor), imaging, nuclear medicine, chapel, parking, support and mechanical space. The project also includes remodeling of the emergency department to accommodate 70,000 patient visits per year and a redefinition of the previously completed masterplan.

The forces that shaped the process for the design of the new acute care tower were driven by the Hospitals' mission, vision and values to extend the highest level of healthcare and improving the quality of life of the people in the communities they serve.

The siting for the new Acute Care Tower was designed to create clear visibility and identity from Medical Center Road. The tower, clad in metal panels and exposed braced structural frame will convey a sense of the highly technological state-of-the-art activities contained within. Extensive glazing will provide an abundance of natural light designed to promote a healing environment for patients, families and an enhanced working atmosphere for the staff. The Chapel is the predominant and most relevant feature of the design of this facility. The Chapel and Meditation Garden are located at the core of the design. This strategic location at the entrance of the new tower makes it readily available to the entire community.

The essential form and character of the Chapel evolved into a half cylinder form with an inclined glass roof structure supported from the top by radial trusses. The dynamic play of light and shadows through the day will fill the space with an inspiring vitality and sense of healing and life.

The oriental theme of this Healing Garden with water displays and beautiful planting invites meditation. It is defined by low radiating walls from the Chapel and it is partially visible from the Imaging department outpatient corridor. The planting and hardscape selected evokes a Zen garden and provides a soft counterpoint to the high tech background of the tower's skin. The braced frame structural system selected for the tower provides superior seismic performance. It is boldly exposed as part of the buildings façade creating a clear geometric order and a unique advanced image to the new tower. This system reduces the size of columns and beams. The main vertical systems such as elevators, stairs, mechanical & electrical shafts are positioned outside the braced floor area. These features maximize the floor area and flexibility of the space to accommodate current and future space programs.

The new hospital tower respects and retains the existing building materials of metal panels and glass, using them in an advanced and unique manner to establish it's own identity and set a new standard for future expansion.
