Sheldon Arleta Park and Landfill, Geotechnical Investigation and Data Report: Subsurface investigation services included a geophysical survey, hollow stem auger borings, and cone penetration tests. A geophysical survey was also performed to assist in delineating the location of an existing underground storage tank. Proposed San Fernando/Cazador Livability Services Division Facility: Geotechnical investigation and construction materials inspection services at the proposed facility. The project design included deep foundations for support of the solid waste collection activities. The investigation was performed using hollow -stem and mud -rotary drilling and associated laboratory testing. During construction, Kleinfelder performed observation and testing of approximately 22-foot deep, 30-inch diameter foundations, concrete inspection and testing, and grading observation and testing. 6. As -Needed Geotechnical Engineering, Materials Testing, Construction Observation, and Inspection I John Wayne Airport I Orange County, CA Year Completed: 2002 — Ongoing I Client: John Wayne Airport, Sean Lally, PE, Airport Engineer, 949.252.6013; slally@ocair.com I Key Staff: Brian Crystal, PE, GE Kleinfelder has provided geotechnical engineering, materials testing, and construction observation and special inspection services at John Wayne Airport for 18 years. We were recently awarded a three-year contract (2017 — 2020) and a two-year extension (2020 — 2022) to continue providing these services. Examples of relevant erects under this contract include the following: Pavement Evaluation for Runway 20R/2L, Taxiway Alpha and Taxiway Lima: Kleinfelder performed a visual evaluation of main Runway 20R/2L, Taxiway Lima, and Taxiway Alpha. The runway is constructed of P-401 asphalt concrete and the centerline was exhibiting a crack along a construction joint. Kleinfelder observed the cracks, collected full -depth cores, and patched the holes with non -shrink grout. The taxiways consist of P-501 Portland cement concrete in slabs ranging from 16 to 25 feet square. Teams of inspectors walked the taxiways at night and documented observed distresses in accordance with the PCI distress codes and plotted the locations on satellite images. Over 700,000 square feet of PCC pavement was observed and documented in four nights. The data was presented in written report with recommendations for John Wayne Airport's pavement repair and maintenance program. Kleinfelder will provide quality assurance and testing services for the rehabilitation and construction of Runway 20R/2L, Taxiway Alpha, and Taxiway Lima. Review of Taxiway Bravo Rehabilitation: Kleinfelder performed a third -party review of a consultant's geotechnical report and pavement design recommendations as well as preliminary 65% design drawings and feedback comments in a letter report to John Wayne Airport. Kleinfelder's experience with FAA pavement design and construction resulted in several comments clarifying the design criteria and potentially avoiding costly post -bid change orders. Terminal C Expansion and Parking Structure C: The project consisted of constructing new Terminal C and Parking Structure C, as well as extending the North Concourse at the northern end of Terminal A. Kleinfelder performed a geotechnical study that consisted of a literature review, subsurface explorations, geotechnical laboratory testing, engineering evaluation and analyses, and preparation of a report. The materials investigation included destructive and non-destructive testing to verify column reinforcing size, spacing and splices, as well as location of post -tensioned tendons and anchors in the deck using ground penetrating radar. Construction services included an indicator pile program to evaluate the pile lengths required to achieve the design capacities and to develop driving criteria specific to the pile driving system; a ground vibration study to evaluate if vibrations induced during pile driving could have an adverse effect on adjacent structures; observation during the installation of production piles to maintain records of pre -drill depths, blows per foot, pile tip elevation, actual pile length installed, pile cut-offs, and installation time; and geotechnical observation and testing services during the preparation of the building pad and other earthwork activities, such as placement of utility trench backfill.
