Charlotte Douglas International Airport Concourse A Expansion Commissioning

Project Summary

Prior to the COVID-19 pandemic, Hanson provided design-phase commissioning services for the 190,000-gross-square-foot expansion of Concourse A at the Charlotte Douglas International Airport in Charlotte, North Carolina, a project that added 10 gates. Hanson was later selected to provide construction-phase commissioning for the project.

The facility’s lower level is dedicated to ramp operations, carrier storage, baggage makeup and mechanical and electrical support. The main level contains the connector with moving walkways, the hold rooms for all departing passengers and space for tenants and concessions. The upper level is a mezzanine comprising mechanical, electrical and telecommunications spaces, as well as a tenant and airline lounge.

In 2019, Hanson provided design-phase commissioning services as a subconsultant to Perkins&Will, the project’s design architect. Hanson’s services under this phase included assisting with the development of the owner’s project requirements, developing the commissioning plan and specifications, reviewing the basis of design and providing thorough design reviews.

In 2023, Hanson began performing the construction-phase commissioning as the prime consultant. The building systems Hanson is commissioning have included heating, ventilating and air conditioning; plumbing; fire protection; electrical; lighting and controls; building automation; elevating and conveying; door access; baggage handling; communications; and building envelope. Hanson has also conducted indoor air quality testing.

The expansion includes seven new variable volume air-handling units with chilled water and hot water coils, ranging from 45 to 115 tons each in cooling capacity. The expansion is served by hydronic piping from the central energy plant serving Concourse A.

The key commissioning tasks during the construction phase include reviewing contractor submittals, developing prefunctional checklists, providing periodic site observations, directing integrated functional testing, overseeing operations and maintenance training and providing a 10-month warranty walk-through.

Hanson is using subconsultants for building enclosure commissioning, indoor air quality testing and supplemental electrical commissioning support from local minority or women-owned business enterprise firms.
