San Diego International Airport is advancing a large Terminal 1 replacement delivered by Turner and FlatironDragados while it modernizes its Central Utilities Plant to support expanded operations, as reported by the project team.
The Turner and FlatironDragados team upgraded the existing plant rather than build a second facility, replacing two 800 ton chillers with two 1,250 ton units, adding a 625 ton heat recovery chiller with buffer tanks, and expanding the cooling tower array with a new 1,250 ton tower, according to project descriptions.
Project work also included a high efficiency boiler, pump refurbishments and replacements, and the addition of seven variable frequency drives to improve control and efficiency. Much of the piping was prefabricated offsite by ACCO Mechanical in Los Angeles, and tie ins were limited to short overnight windows so the CUP remained operational during construction.
A concurrent half mile hydronics linkage connected the plant to the new terminal, with piping installed at depths up to twenty feet and bores beneath an active roadway to keep traffic moving. The upgraded plant now delivers 5,000 tons of cooling and 26 MMBH of heating capacity and was finished four months before the terminal building flush milestone, giving the team time to commission systems before tie in, as reported by the project team.
Operational Disruptions And Passenger Reaction
Stormy weather and staffing strains produced a separate challenge for San Diego International Airport, with flight tracking data published on airport and aviation websites showing at least 140 delayed flights and two cancellations, as reported by coverage of the disruption.
The National Weather Service issued a flood advisory and strong wind warnings that flagged coastal gusts up to 45 to 50 knots, and the FAA showed only short airborne and ground delays of 15 minutes or less at its latest update, a contrast noted in reporting on the incident.
Ground operations were also strained by reported staffing shortages among TSA and air traffic controllers. A senior airport official speaking on condition of anonymity described workforce pressure, and TSA representatives confirmed some agents were working extended hours while others took time off, according to news reports.
Passengers reported long waits, and a San Diego resident told a local news crew they arrived more than four hours before departure only to be told their flight was delayed with no new departure time. The San Diego County Regional Airport Authority urged travelers to check airline status and allow extra time, as noted by the authority.
Separately, social media attention focused on a Reddit post showing a handwritten thank you note to a passenger named Samuel on a Southwest aircraft, prompting both skepticism and defense among online commenters. The publisher of that report said it had contacted Southwest for comment.
