New Patient Tower, Sibley Memorial Hospital

This project comprises the addition of a 9-story, 450,000 sf addition that will be utilized for inpatient beds at Sibley Memorial Hospital in Washington, DC, part of the Johns Hopkins family of healthcare institutions. It is the third phase of a three-phase project that includes a new medical office building and garage (phase 1), and a new Cancer Center (phase 2). This phase included the creation of a new front entrance and completed the major addition to what is now known as the “New Sibley."

The new patient tower includes a new emergency department, new inpatient pharmacy and connecting bridge to the existing tower building. The inpatient tower provides 263 new all private rooms including shell space for a 20 bed expansion. The initial fit out consisted of a 20 bed Labor and Delivery unit, sized for 4,000 annual births, with three new c-section rooms, a 20-bay special care nursery and a 50-bed postpartum support component.

A new 25-bed telemetry/IMC unit is located adjacent to a new 25 bed orthopedic unit. The remaining beds are for medical/surgical patients. A new and expanded emergency department, sized for 45,000 visits per year, provides new treatment bays including a new fast-track area and new waiting areas. A new single story entry pavilion acts as the new main entry and lobby space for the project. Minor renovation work was performed in the existing hospital to allow for the connection at several of the lower floors.

The project included a chilled water plant that is expandable for future use as the primary chilled water plant; heating hot water boilers; domestic water plant; medical gas systems; custom air handling units; emergency generator plant; and normal and emergency power distribution that serves the new addition. In addition, this project provides the generator plant for the campus, which will be housed on the roof.

Leach Wallace utilized Revit as our BIM software for this project. This project was designed as a LEED® certified facility. The facility is scheduled to open in September 2016.
