This study will be required to provide monthly and annual total counts, and characteristics of aircraft operations at approximately 57 public-use non-towered airports and 18 public-use towered airports throughout the state of Illinois. An essential part of providing annual aircraft operations counts and aircraft characteristics at airports is the collection of sample data for extrapolation, using methods such as visual imagery and/or Automatic Dependent Surveillance-Broadcast (ADS-B)/Mode C transponders, to determine the type and quantity of aircraft operations. These data are necessary to fulfill requirements set forth by the Federal Aviation Administration (FAA) through the State Block Grant Program, individual airport planning/design, and the practice of Integrated Airport System Planning and the Airport System Planning Process. Annual total aircraft operations count, including meta-data on characteristics such as aircraft type-make-model, utilized in determining existing and future critical aircraft. The Prime firm must be prequalified in the Airports (Master Planning/Airport Layout Plans (ALP) category to be considered for this project. Statements of Interest, including resumes of only the key people noted above, must be submitted electronically to the Central Bureau of Design and Environment through the Engineering Prequalification and Agreement System (EPAS).
