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
