EXECUTIVE SUMMARY 
The IAF work has not completed construction in a timely fashion. The project was anticipated to
be complete in early June 2020 and now is expected to be completed in June - July 2021. The

provide construction inspectors, resident engineers, construction managers, project managers,
engineering specialty consultants, security personnel, operational personnel, etc. to manage
work around aircraft gates, monitor and review contractor submittals, perform quality checks,
and manage the program, it is necessary to extend the budget for 13 months resulting in this
authorization request totaling $18.2 million. 
JUSTIFICATION 
It is necessary to extend Port staff coverage of the program for the period of time during which
the prime design-builder will be completing their work.
