Project Value $12 billion

The World Trade Center site is a 16-acre section of downtown Manhattan surrounded on either side by Church, Liberty, Vesey, and West streets. The Downtown Restoration Program involves redevelopment of the facilities at the World Trade Center site destroyed in the attacks of September 11, 2001.

Hill was retained by the Port Authority of New York and New Jersey (PANYNJ) to provide program management services for this complex and highly visible capital program. Hill’s program management services included scheduling, estimating, cost modeling, budgeting, and cost controls for each of the capital projects. In addition, Hill provided design reviews, value engineering, and constructability studies.

Hill developed a comprehensive cost model that incorporated all of the capital costs for the programs, valued at more than $12 billion. The model used a WBS system that allows queries of multiple elements to generate task-specific reports, allowing management to make informed decisions as the programs have developed from conceptual design through the construction phases.

Hill also worked on the development of a tailored Integrated Master Schedule (IMS) for the program. The IMS provided schedule information for each of the various projects going on at the World Trade Center site. These projects include PANYNJ’s World Trade Center Transportation Hub, the new Freedom Tower, the Memorial Museum, the Vehicular Security Center and Tour Bus Parking Facility, the chiller plant, streets/utilities, parking facilities, and tenant retail.

The data contained in the monthly updates of the IMS was then used to create monthly cost and schedule reports for PANYNJ. The IMS merged and summarized detailed design, procurement, and construction schedules of each of the World Trade Center construction projects and was a valuable working tool for coordinating the program, and for identifying issues among myriad external agencies and private firms that also are involved. The IMS was also used to set project target dates and milestones for those aspects of the work being done per Federal Transit Administration requirements.

World Trade Center site restoration projects included:

World Trade Center Memorial & Museum: Located on nearly half of the site’s 16 acres, the memorial and museum is dedicated to honor the thousands of people who died in the attacks of February 26, 1993, and September 11, 2001. Designed to reflect absence, the memorial consists of two massive voids that reside in the footprints of the original Twin Towers.

World Trade Center Transportation Hub: Designed to serve approximately 250,000 commuters per day, this full-service, regional transportation hub meets the redeveloped needs of the World Trade Center and the surrounding neighborhood, while ensuring long-term accessibility in, and the economic growth of, Lower Manhattan.

One World Trade Center: The 1,776-foot-tall One World Trade Center includes 2.6 million SF of office space, tenant amenity space, an observation deck, restaurants, and a broadcast facility.
