Exhibit A, Scope of Work <br />INTRODUCTION <br />The Washington State Department of Transportation (WSDOT) is responsible by law for the conduct <br />and management of all aerial search and rescue within the state. This includes search and rescue <br />efforts involving missing aircraft and crew members/passengers. This is carried out directly by WSDOT <br />and with the assistance of many partners that provide resources to search for and rescue persons who <br />end up in a remote or hostile environment after being forced down in an aircraft (RCW 47.68.380). <br />A tool available for conducting this work is a new system mandated by the Federal Aviation <br />Administration (FAA) called Automatic Dependent Surveillance — Broadcast (ADSB). Under this rule, all <br />civil aircraft that operate in most classed or controlled airspace are required to have equipment on their <br />aircraft that continuously broadcasts 19 pieces of data about the aircrafts position in space every <br />second while in flight and taxing. This information is available to other aircraft equipped with "ADSB In" <br />systems and to the public through specialized websites. One aspect that helps populate the public <br />websites with this data is the deployment of ADSB receivers by individuals and organizations to provide <br />coverage in areas where the FAA system has gaps in reception. <br />WSDOT desires to install ADSB receivers in key locations around the state to provide coverage in <br />collecting aircraft flight data to assist in locating lost, missing, or overdue aircraft. More precise <br />information about an aircraft's path and possible last location can greatly aid WSDOT in locating the <br />aircraft and deploying critical care resources and transportation to a medical facility. This strategy is <br />mainly focused on using WSDOT facilities but there is also an advantage in using other structures that <br />are located in areas that would provide valuable coverage. <br />This agreement enables improved ADSB monitoring coverage and enhances the safety of the flying <br />public in Washington State by allowing WSDOT to use other facilities. This Scope of Work exhibit gives <br />a general description of the types of work and equipment that WSDOT may deploy on non-WSDOT <br />owned property. <br />Work described in this exhibit pertains to the installation, and ongoing maintenance, of ADSB receiving <br />equipment and/or associated infrastructure, communications, and electronic equipment. The work, <br />infrastructure, and equipment described in this exhibit is not comprehensive but is intended to generally <br />represent activities facilitating the collection and transmission of aircraft ADSB flight data to a host <br />server. <br />INSTALLATION WORK <br />Conduit assembly and emplacement; enclosure assembly and emplacement; wall mounting; tower <br />climbing and mounting; cable management; framework assembly; power system assembly, <br />emplacement, and connection; communications equipment assembly, emplacement, and connection; <br />and other installation work intended to facilitate the collection and transmission of aircraft ADSB flight <br />data to a host server. <br />MAINTENANCE WORK <br />Site visits; IT troubleshooting; electrical troubleshooting; equipment repair and replacement; <br />infrastructure repair and replacement; and other maintenance activities intended to facilitate the <br />collection and transmission of aircraft ADSB flight data to a host server. <br />WSDOT Agreement GCB 4098 Page 6 of 8 <br />
