The $5.1-billion Salt Lake Town World Airport Redevelopment is wrapping up its Section 4 Concourse B growth and delivering the overall seven passenger gates on October 27. This milestone represents 10 years of intense airfield phasing and complicated engineering coordination to stay a hectic airport operating for 35 million passengers.
One of the vital challenge’s largest demanding situations was once construction the brand new gates proper subsequent to lively taxiways.
To take care of secure airplane get right of entry to to and from gates thru lively building zones, the group followed an “airport operations come first” way, organising building paintings spaces handiest after figuring out the setbacks required for gate get right of entry to, airplane pushback and tug operations, says Robert Millar, aviation challenge director for lead design company HNTB.
“HNTB coordinated carefully with (terminal architect) HOK and airline stakeholders to align terminal and civil building schedules, making sure current gates remained operational till alternative gates have been to be had,” says Millar. “Particular consideration was once given to keeping up widebody airplane get right of entry to to foreign arrival gates till new international-capable gates got here on-line.”
The group additionally constructed detailed blueprints to stop carrier outages. Millar says the jet gas sequencing plans have been “in particular detailed” and incorporated coordination with uniqueness installers and checking out contractors to facilitate in a single day shutdowns for flushing, checking out and tie-ins to the present gadget to keep away from disruptions to airline fueling operations.
Secure crane operations have been any other problem, requiring coordination between HNTB, the FAA, airport stakeholders and the joint-venture group of Holder Building and Giant D Building (HDJV). Millar says HNTB helped put in force a variety of methods, together with mapping and designing transient “crane roads” across the concourses for the crawler cranes to make use of, and operating opinions to verify that enormous building cranes didn’t block the air site visitors regulate tower’s view.

Brent Christiansen, superintendent for HDJV, says to execute heavy crane maneuvers safely, box groups needed to take care of a inflexible regulatory agenda and adapt continuously to transferring visibility. “The FAA required a weekly 7460 assembly to coordinate the spaces of affect, in addition to atmosphere a ceiling for lifting operations and hours,” he says. “Unhealthy climate was once the most important problem because of ILS (Software Touchdown Methods) operations and its necessities. The group needed to regularly watch the elements and be able to decrease and transfer apparatus at a second’s realize as a way to no longer intrude with ILS operations.”
A novel side of this system was once extending an current passenger tunnel that were built years previous and preserved as a long run connection level. “When the tunnel was once ultimately excavated and prolonged to serve the brand new concourses, the group needed to cope with a number of advanced engineering concerns to seamlessly attach the brand new and current buildings,” says Millar.
To anchor the tie-in, the group designed transient shoring to carry down the tip of the present tunnel after taking away overlying soils. “The extension additionally required cautious attention of the joint design between current and new buildings to mitigate towards differential agreement, in addition to to offer waterproofing continuity between the brand new and current tunnel sections,” says Millar.
The challenge’s of completion brings the airport’s overall capability to 94 gates. Whilst a separate three way partnership of Austin Industrial and Okland built the Concourse B amenities beneath a $545-million contract, the seamless of completion of the section effectively wraps up greater than a decade of grasp plan growth throughout 4 levels, updating all the airfield footprint.
