Sci-Tek provided geotechnical engineering and environmental consulting services for the Philadelphia International Airport (PHL) Taxiway S Reconstruction Project. The project was divided into three phases: package 1, package 2, and package 3. Sci-Tek provided geotechnical services for all three packages and environmental services for package 1. As a subconsultant to JMT, Sci-Tek provided the following services:

  • GEOTECHNICAL ENGINEERING
    • Drilled borings on Taxiway S and its shoulder to estimate the existing pavement thickness and characterize the subbase and subgrade soils.
    • Performed borehole infiltration testing within the footprint of the proposed stormwater best management practices.
    • Performed engineering analysis based on the data obtained at the test borings and laboratory test results including, CBR, Atterberg limits, modified proctor, compaction, consolidation, and shear.
    • Prepared a Geotechnical Subsurface Exploration Report with professional conclusions and recommendations for the proposed Taxiway S pavement and sub-grade reconstruction and a summary of the stormwater infiltration testing and results.
  • ENVIRONMENTAL CONSULTING
    • Provided a Limited Phase II Environmental Subsurface Investigation of Taxiway S in the vicinity of sub-taxiways S4 and S5 to evaluate the presence/absence of potential subsurface concerns.
    • Coordinated ground-penetrating radar and magnetometry and Geoprobe soil borings.
    • Collected samples for Clean Fill analysis, de-icing constituents, and PFAS compounds.
    • Provided a Limited Phase II Investigation report with field and laboratory results, photographs, professional conclusions and recommendations.
