The scope of the project was to conduct asset condition assessments and retro-commissioning on terminal facilities at George Bush Intercontinental Airport (IAH), William P. Hobby (HOU) Airports, and other airport owner facilities at IAH in Houston, Texas. The facilities included at IAH were Terminals A, C, D, and Federal Inspection Station (FIS) Terminal, the Consolidated Rental Car Facility (CRCF), and the Vehicle Maintenance Facility (VMF). The Terminal facility at HOU was included in the assessment and retro-commissioning project. Additional facilities at IAH included two commercial aircraft hangars and cargo facilities. The overall objectives of the project included:

• Assess and collect information on the life-cycle design, operating, and physical condition of Houston Airport System (HAS) assets.
• Determine the ability of the asset to meet needs and determine the effective remaining service life.
• Combine retro-commissioning with condition assessment for greater value.
• Establish original performance criteria for systems and measure current operating parameters.
• Identify variations in system performance from desired criteria.
• Recommend potential repairs, adjustments, and improvement measures to optimize systems.
• Provide quantifiable value and savings data for recommendations.
• Develop and execute a measurement and verification strategy to verify savings and enable better maintenance of retro-commissioned systems.

Sunland staff was a major component of the team to complete these asset inventory assessments and develop cost and sequence strategies for required maintenance or potential renovation or replacement. The evaluation process included current architectural, structural, civil, and MEP systems status, recommendations, and prioritization for potential repairs, adjustments, and improvements. This project was completed on a very aggressive schedule and required the mobilization of multiple teams of staff on-site at the Houston Airport System (HAS) facilities for several weeks. Sunland staff also assisted with the development of the database support documents to establish baseline conditions.
