Program Management

The Capacity Enhancement Program (CEP) is a $6.4 billion comprehensive construction program to expand and modernize Philadelphia International Airport (PHL) over a 10-12 year period that will improve crucial aspects of traveler accessibility and convenience. CSA Group is the lead structural engineer on the Program Management Team and is also providing civil engineering for required changes to landside roadways and bridges. Our work to date includes:

Standard Structural Design Guidance

Based on CSA’s 30 years of experience working with airport structures, standard design guidance for foundation systems was prepared for the Program Management Team and future design teams that will be engaged to complete the CEP program.

Automated People Mover (APM) Passenger Facilities - Structural and Civil Conceptual Design:

CSA is providing consulting services in the fields of civil and structural engineering, related to the APM system guideway supports, APM stations and platforms, vertical passenger circulation, and station /terminal connecting elevated walkways and road and bridge design, including related civil and structural engineering, for the existing roadways and highway ramps impacted by the APM project. CSA is developing Interface alternatives for grade separations for the arrivals road, commercial road, garage access and exit roads, terminal recirculation loop, Interstate access ramps and, if applicable, the airport departures road. The tasks required include a review of existing documents, survey, data collection, analysis, budgetary cost estimates, conceptual designs, and recommendations. Our effort also includes development of preliminary conceptual layout of roadways and ramps options; conceptual layout of platforms/vertical circulations/stations/connection walkways and associated recommendations. We will also support and assist other members of the APM task order team with the planning and conceptual design.

Airport Terminal B/C Expansion Structural Scheme

CSA is providing staff to review the potential expansion of the second level of Terminal B/C and evaluation of the structural scheme to accommodate the expansion over the arrival drive. The work requires review of existing documentation, identification of any fatal flaws that would preclude the expansion, development of design criteria for all codes and standards, and preliminary sketches for evaluation of the proposed expansion.

CONRAC Parking Garage – new addition

The Philadelphia International Airport CONRAC project is a proposed 7-story parking garage structure that includes the CONRAC Building, Site Utilities, Building Utilities and Systems, Site Development, Building Structural, Ground Transportation Planning, Roads Conceptual Engineering, and APM Coordination. The parking structure will fill most of a 33.4-acre site immediately adjacent to the existing toll plaza. The site is now occupied by 5 buildings on three parcels that are to be demolished. The CONRAC building will be served by the future Automated People Mover. Busses and access roads will be necessary on the grade level through the structure for bus access and circulation by other vehicles and gasoline storage on the site for rental vehicles will be required. Philadelphia Water updated its Stormwater Regulations for development projects that went into effect on 7/1/2015 to meet requirements of the Clean Water Act. These new rules will be reviewed and applied to this project.

CSA’s civil engineering scope includes surveying the existing buildings on site, review of the existing storm sewer infrastructure on and near site, definition of the grading plan, storm drain and stormwater management, site plan, soil erosion and sediment control, and sizing of storm drain pipes and stormwater management facilities. Structural scope includes inventory of existing building and structures for demolition, review of geotechnical information, develop structural design criteria and approach as well as basis for selected design, coordination of layout of column spacing, exit ramp locations and slope, identification of test boring program and special inspection program requirements per IBC and L&I, preparation of DPP narrative and comprehensive coordination with owner and design team.

CSA is a subcontractor to the Global Program Partners Joint Venture comprised of CH2MHill, Delon Hampton & Associates and CMTS, Inc.
