Children's Hospital of Philadelphia is building the $496 million Colket Translational Research Building on its South Campus. Slated for completion in 2010, the 450,000-sf, eleven-story facility will include four laboratory floors, administrative offices, a cafeteria, conference space, and a two-story lobby. Four below-grade floors will house infrastructure, laboratory support, and a central utility plant. Office floors are designed for ease of conversion to laboratory space, and the building is constructed to expand vertically to 23 stories to accommodate future growth.
