PHL - RUNWAY 27L EXTENSION  AND ASSOCIATED TAXIWAYS

Three-phase project to construct a 1494 linear-foot extension to the current Runway 9R-27L. Package 1 (PHL-1640.24) included site preparation, utilities and fuel line relocation; Package 2 (PHL-1640.44) included the runway and taxiways; and Package 3 (1640.54) included Taxiways, Parts A, B, C, & D. The project included the construction of associated eastside Taxiways and Hold Aprons. A new Taxiway EE will establish a connection between Taxiways H and K. Taxiway H will be realigned between Taxiway EE and the existing Taxiway D. Additionally, a wide service road will be constructed, the existing tide gate will be investigated, drainage and electrical utilities will be relocated, and two (2) 20 inch diameter steel pipes will be added to transfer jet fuel from the tank farm to the truck fill area. 

Balter provided field and laboratory testing and inspection services. Field services included the testing and inspection of P-152, P-209, P-401, P-403, P-501, and P-610. Laboratory services included testing P-152, P-209, and P-501 materials. P-401 and P-403 Hot Mix Asphalt mixtures were tested at a plant laboratory producing the HMA with NICET certified CMT Asphalt Level III and Level IV Technicians who calculated volumetric properties and percent within limit (PWL) values to determine Contractor pay. Balter provided randomly selected sample locations for all HMA plant testing as well as the mat and core locations. PWL calculations were also determined for P-501. 

PHL Construction Management (CM) Services for the Capacity Enhancement Program Stage I Airfield Development Project: Runway 27L Extension and Associated Taxiways - Philadelphia, PA  Technician responsibilities included the review of plans, specifications, submittals, RFIs and shop drawings; attended preconstruction, pre-work and progress meetings; provided construction management/materials support reviewing design documents and comments, coordinated with DOA Project Managers; provided QA and Acceptance Testing during construction of airside improvements as well as asphalt plant inspections.  Balter established protocol to incorporate an on-site material testing facility. The condition of a previously used on-site laboratory for the testing of soils, concrete, and asphalt was evaluated. The existing equipment was examined and assigned condition values to establish what could remain and what needed to be replaced. Additionally, and assessment was conducted to ascertain what additional equipment would be required. Cost estimates were prepared to reestablish the laboratory to a satisfactory working condition and to have the laboratory accredited to the appropriate testing and quality ASTM Standards. The documentation for all inspections and associated materials laboratory test results were reported to PHL authority.
