Project Benefits
Aviation Commercial Management (AVCM) is able to lease
11,000 square feet of new space in the Central Terminal;
previously unused space on the north and south mezzanine
levels
Upgrades the infrastructure in all of the Central Terminal
tenant spaces.
Improves HVAC system in the Central Terminal
Improves the customer experience

Lessons Learned Design and Construction
Include a plan for customer service impacts during construction
Plan for budget and schedule impacts for pest mitigation
Perform additional site investigation
Plan for ADR cleaning and operational readiness in the schedule
Establish schedule breaks between contractors and tenants - avoid
both parties working in same space at the same time
Better coordination between projects and tenant contractors for lay
down space

Project Benefits & Rationale
2016 ADR Demand Analysis showed a significant shortfall of food and beverage
space to meet the forecasted passenger demand in 2025
Staff looked throughout the main Airport terminal building for space that could be
utilized to meet this shortfall
The mezzanine spaces on the north and south sides of the Central Terminal were
determined to be the best alternative for reducing the shortfall relative to the
forecasted demand
This project is necessary to make these spaces leasable
Upgrades the infrastructure in all of the Central Terminal tenant spaces.
Improves HVAC and system in the Central Terminal
Improves the customer experience
