The University of Pennsylvania Health System plans a new office tower at the current site of a mostly empty lot at 3600 Civic Center Blvd. to be built in phases beginning in early 2017, an official said.

The 540,000-square-foot, 18-story Center for Healthcare Technology building is to be constructed beside an existing patient parking garage that opened in 2015, Penn Medicine spokeswoman Susan Phillips said in an e-mail on Wednesday.

The building's first phase of construction will result in a 250,000-square-foot, eight-story office building for Penn Medicine corporate functions, including information technology and human resources, and a childcare center for the institution's employees, Phillips said. A second phase of 290,000 square feet will be added later, she said.

Philadelphia's Civic Design Review board, which makes nonbinding design suggestions for the city's biggest development projects, is scheduled to consider the proposal on Aug. 2, according to the panel's website.

Plans posted to the site name Perkins & Will as architect for the glass, aluminum and precast-concrete structure.

Penn Medicine's development plans also include a new hospital building at 300 S. 33rd St. to take the place of the university's Penn Tower structure once its demolition is complete.

Philadelphia's planning commission has approved plans for the 343-foot-high, 1.1 million-square-foot New Patient Pavilion being designed by architecture firm Foster + Partners at a meeting in May.

The building will serve as a patient-intake hub for surrounding medical facilities, a Penn Medicine representative said at the time.
