Bored Tunnel Alternative Design-Build ProjectDesign-Build Construction Management ServicesSR 99ARC Tunnel Project/Trans-Hudson Express Tunnel ProjectNewark, NJPROJECT DETAILSClient Representative:Newark, NJContract Dates:6/09 - 10/10Total Dollar Amount:$8.7 billionServices Provided:Construction ManagementPROJECT BACKGROUNDThe CM Consortium tri-venture was contracted by New Jersey Transit for project control and construction management(PCCM) services in support of the Access to the Region‘s Core (ARC) project, and selected the ARC alternative known as theTrans-Hudson Express Tunnel Project. This project doubles the rail capability from New Jersey into midtown Manhattanthrough construction of the following:• Platform, concourse, and track improvements to the existing Frank R. Lautenberg Station in Secaucus, New Jersey• Two new single-track tunnels beneath the New Jersey Palisades (hard rock TBM tunnels) and the Hudson River (softground earth pressure balance TBM (EPBM) tunnels) connecting with four single-track tunnels in Manhattan (hard rockTBM tunnels)• Construction of the New York Penn Station Expansion to the north under 34th Street between 6th and 8th Avenues• Improvements to rail infrastructure in New Jersey to provide expanded one-seat-ride opportunities to midtownManhattan from various rail lines• Supporting investments such as electrification, traction power, track improvements, rail yards, signal systems, and facilitiesSignificant Challenges and/or InnovationsAlthough the project was suspended during the initial stages of construction, the CM Consortium developed numerousinnovations during pre-construction. Responding to public concerns for providing safe, reliable transportation thatpromotes sustainable commuting patterns was at the core of the ARC project. Rail transit promotes sustainability byreducing emissions and providing an efficient, economical, and environmentally conscious way to travel. By doubling therail capability from New Jersey into Midtown Manhattan, the ARC project would have allowed more people to use this“green” form of transportation as their primary means of commuting.Sustainability is also being incorporated into the project through various construction methods. For instance, the New YorkPenn Station Expansion (NYPSE) cavern, the largest underground station in Manhattan, was scheduled to be constructedusing green building practices that reduce water usage and heating and cooling loads. During construction, the contractorwould have been required to meet significant guidelines with respect to air quality and emissions.Roles of Major ParticipantsParsons is the managing partner for the CM Consortium tri-venture. The CM Consortium is contracted to perform servicesthat align with a conventional construction management function and a project controls/oversight function. Majorservices included in the CM Consortium’s scope include review of preliminary engineering design work for constructability,review of geotechnical methodologies, development of a project control plan, review of the baseline budget preparedby the partnership design team, and resident engineering and inspection services. In addition, the CM Consortium isrequired to provide various other services, including developing a plan to control the scope and budget, supporting aproject management plan that integrates design and construction, developing a risk management plan, and developingthe Procedures Manual, which is intended to document the applicable quality management responsibilities of the CMConsortium through the life of the project.12
