"Based on that information, the CCD originally set late spring 2014 or early summer as the completion date. But during underground excavation through 2012 and 2013, as we worked around active SEPTA transit lines, crews encountered many old pipes and concrete stairwells that predated Dilworth Plaza."
Although nearly all the underground demolition has been completed and much of the structural slab has been poured, Levy said the unforeseen circumstances have upped the project's price tag to $55 million, roughly 10 percent more than the original estimate.
Throughout the life of the project, though, Levy said, it is fiscally sound through ongoing fundraising efforts. It is paid for by state and federal grants, the city of Philadelphia, SEPTA and local foundations.
Often compared to Manhattan's Bryant Park and Boston's Post Office Square, the rejuvenated Dilworth Plaza is expected to bring a wealth of new tourism interest to Philadelphia.
"When this facility opens, I think Philadelphians will come in droves to experience it," mayoral spokesman Mark McDonald said.
"We understand that the project managers and their contractors found some stairwells and other things that were not in the original plans, and that required more time. There's still a good bit of work yet to be done and paid for, but I think the main issue here is that it's going to be a truly beautiful addition to an iconic structure in the heart of the city, and one that will attract many residents and visitors."
When finished, the new Dilworth Plaza is envisioned to boast wide, open green spaces, a cafe, a state-of-the-art outdoor venue for concerts and special events, and a customizable water fountain that can be transformed into an ice-skating rink in the winter.
