- Condition Assessment & Retro-Commissioning
The Houston Airport System (HAS) selected us to perform condition assessments combined with retro-commissioning for more than 6 million square feet of terminal, commercial and support facility infrastructure at William P. Hobby Airport (HOU), George Bush Intercontinental Airport (IAH) and the IAH Consolidated Rental Car Facility.
The condition assessment program was intended to determine the current condition of facility infrastructure and provide recommendations to optimize and improve them from the existing state. This also included recommendations for operations and maintenance improvements as well as cost estimates for deferred maintenance and replacement value of systems and components.
The retro-commissioning program identified improvements and modifications to the HVAC system, which are projected to produce savings of approximately $1.6 million per year when implemented. Our team performed the condition assessment and retro-commissioning for the Consolidated Rental Car Facility, Terminals A and C, the Federal Inspection Services (FIS) facility at IAH, and the entirety of HOU. Condition assessments were also performed for Terminal D, the vehicle maintenance facility, three cargo facilities and two hangars at IAH. The condition assessments included architectural, structural, mechanical, electrical and plumbing, baggage handling systems, conveyance, passenger boarding bridges, and limited civil systems.
- Condition assessment
This comprehensive effort involved review of design and record documents; interviews with HAS staff to gain customer and stakeholder input; utility and energy analysis; hands-on operational inspections, assessments, systems testing and adjustments; and integrating data into an existing asset management system.
Field data was captured electronically via tablet computers using a custom Facility Assessment Data Collection Tool (FADCT) that uses a combination of mobile computing, barcoding, GIS and database technologies. The FADCT enables condition assessment and retro-commissioning data to be collected, analyzed and integrated into the HAS enterprise asset management system (Infor), efficiently, accurately and with minimal effort.
The entire program was completed within one year with the bulk of the field effort being performed inside a five month period using multiple concurrent engineering teams. We managed the program to meet a 30 percent DBE subcontracting goal, partnering with Texas A&M Energy Systems Laboratory, as well as coordinating with LeighFisher Associates and Ricondo & Associates, who were the primary contract holders with HAS.
