2022 Project Risks
RISKS                 DESCRIPTION            PROBABILITY   IMPACT   MITIGATION
FAA funding application        For projects with FAA              Low                High          Close coordination with the FAA Region and ADO.
discretionary funds applied to                                          Postpone construction work until receiving FAA
majority of work, the grants                                            discretionary funds
need to be received prior to
issuing NTP. Any delay by FAA
could delay the overall project

and supplier agreement                                            targeted acceleration, as necessary
negotiations might impact
construction if there is a strike
Weather delays               Potential delay to the overall      Low               Med          Contingency dollars will be used for targeted
construction project due to                                            acceleration when weather is favorable
inclement weather
