Some of the highest-profile construction projects in the world right now aren't being built on empty lots. They're being built inside, around, and underneath facilities that never get to close. Airports that can't ground their flights. Hospitals that can't discharge their patients for a renovation. In 2026, a wave of major terminal and hospital projects — from New York, USA, to Auckland, New Zealand — are proving out what it actually takes to build big while the doors stay open. That's a fundamentally different logistics problem than a standard greenfield site, and it's one more construction teams are going to face as aging infrastructure gets rebuilt in place instead of relocated.

Why Are So Many Airports and Hospitals Being Rebuilt at Once in 2026?

Two forces are converging. Passenger and patient volumes have outgrown infrastructure built decades ago, and public budgets are finally catching up after years of deferred investment. In Singapore, the Building and Construction Authority expects S$47 billion to S$53 billion (roughly US$37 billion to US$42 billion) in construction contracts to be awarded in 2026 alone, with Changi Airport's Terminal 5 as the single largest driver. In Australia, Infrastructure Partnerships Australia is tracking 54 major hospital projects worth a combined AU$42 billion either under construction or awaiting the start of work, with 29 of them worth AU$22.8 billion due to begin by the end of 2026. Neither of those pipelines is slowing down, and both are running through live facilities almost by necessity. There's rarely a version of "close the airport" or "close the hospital" on the table.

How Do You Build a New Terminal Without Shutting Down the Airport?

This year has already delivered proof it can be done on a large scale. At JFK International Airport in New York, USA, the $4.2 billion first phase of the new Terminal 6 opened in spring 2026 with 10 gates, nine of them widebody-capable, as one piece of the Port Authority's broader $19 billion transformation of the airport. Weeks later, the airport's New Terminal One opened its first 14 gates in June 2026. The full terminal is not due for completion until 2030, meaning construction and live operations will run side by side at JFK for years to come.

A few hundred miles south, Washington Dulles International Airport, in Virginia, USA, is completing its first new concourse in more than two decades: the roughly 435,000-square-foot, $500 million Concourse E, connected to the airport's underground train system and set to open in late 2026.

In Canada, Toronto Pearson Airport, in Ontario, launched the first CA$3 billion phase of its decade-long "Pearson LIFT" modernization program in May 2026 — new taxiways, 20,000 smart LED airfield lights, and a replacement of 30 kilometers of baggage belts. This is all aimed at growing the airport's capacity from roughly 45 million to 65 million passengers a year without a single day of closure.

And in Auckland, New Zealand, contractor Southbase Construction is rebuilding the airport's check-in area as part of a NZ$5.7 billion terminal program the company itself has called one of the most complex projects it has ever undertaken — precisely because every phase has to happen without disrupting a live international airport.

What Does It Take to Build a Hospital Tower While Patients Are Still Inside?

Hospitals raise the stakes further, since the "live operations" being protected are patient care and emergency response, not just passenger convenience.

In Columbus, Ohio, USA, the Ohio State University Wexner Medical Center opened its new $1.79 billion, 26-story, 820-bed tower in February 2026. A 1.9-million-square-foot facility with 24 operating rooms and 234 ICU beds that replaced two older buildings without interrupting hospital operations during construction.

In Mississauga, Ontario, Canada, work is well underway on the new Peter Gilgan Mississauga Hospital, a full replacement of the existing facility that the Ontario government has cost more than CA$14 billion. A 22-story, 2.8-million-square-foot building with more than 950 beds, set to become one of the largest teaching hospitals in Canada when it reaches substantial completion in 2033.

In Singapore, planning is underway for a new general and community hospital in Tengah, part of a national plan to add roughly 13,600 hospital beds between 2025 and 2030.

And in Auckland, New Zealand, contractor McConnell Dowell just handed over a striking proof point: a new five-story, seismically resilient central plant building and a 240-meter service tunnel at Auckland City Hospital, delivered on time, on budget, and with a strong safety record over a four-year build — on a site the project team has described as one of the most complex stakeholder environments in the country, with patients, staff, emergency vehicles, and even a helicopter pad all operating within the same small footprint.

What Makes Live-Facility Construction Logistics Different?

Across every one of these projects, the same operational pattern shows up. Deliveries have to be scheduled around passenger and patient flow, not just crew availability. Exclusion zones around active work areas have to be communicated to every driver and contractor before they arrive, not discovered at the gate. Every vehicle and every worker needs a verified induction and credential check, because a wrong turn near a runway or an ICU has consequences a standard commercial site doesn't carry. These sites are so publicly visible, there's little tolerance for the kind of informal, radio-and-memory coordination that a quieter greenfield project might get away with.

The Auckland City Hospital project is a useful example of what "getting it right" looks like in practice: a custom traffic management plan that physically separates construction vehicles from hospital traffic, including a dedicated access ramp to keep trucks away from patient-facing areas altogether.

We've seen this play out firsthand. On the St Vincent's Private Hospital expansion in Sydney, Australia, Buildcorp was managing a new 13-level building — multiple cranes, material hoists, loading areas, and an offsite warehouse — on a hospital site that never stopped operating. Before implementing Veyor, coordinating that meant up to 30 phone calls a day and a 30-minute whiteboard meeting just to plan the next day's deliveries. After: crane meetings dropped from 30 minutes to 10, disputes over bookings disappeared, and the site team shared control of the hospital's operational loading dock with the hospital's own dock master, without it becoming a daily negotiation. Over 7,000 deliveries and material movements later, the project is a working example of what coordinated logistics looks like on a live hospital site, not just a theory of it.

FAQ: Construction at Live Airports and Hospitals

Why are so many airports and hospitals being rebuilt in 2026?

Decades-old infrastructure is being replaced just as passenger and patient volumes outgrow it, and major public capital programs — such as Singapore's S$47–53 billion 2026 construction pipeline and Australia's AU$42 billion hospital pipeline — are now funding that replacement. Because these facilities can't simply close, nearly all of this work is happening on live sites.

How do airports keep operating during major construction projects?

By phasing work so new gates, concourses, or terminals open incrementally rather than all at once. JFK International Airport, in New York, USA, opened Terminal 6's first gates and New Terminal One's first gates within weeks of each other in 2026, while the rest of the airport continued normal operations. Toronto Pearson Airport, in Ontario, Canada, is taking the same phased approach over a decade-long program.

How do hospitals manage construction without disrupting patient care?

Through strict physical separation of construction traffic from patient and staff areas, verified contractor inductions, and scheduling that avoids peak clinical activity. Auckland City Hospital's Central Plant and Tunnel project, in New Zealand, used a dedicated access ramp to keep construction vehicles entirely away from hospital traffic during a four-year build.

What is a construction exclusion zone?

An exclusion zone is a defined area around active construction work — such as a crane's swing radius or an electrical works area — that vehicles, pedestrians, and unauthorized personnel are restricted from entering. On live-facility sites, exclusion zones need to be communicated to every driver and contractor before arrival, since discovering one at the gate creates delays and safety risk.

What's different about delivery scheduling on a live airport or hospital site?

Delivery windows have to work around passenger flow or clinical activity, not just crew availability, and every vehicle needs a verified booking and credential check before it arrives. That's a higher bar than a standard commercial site, where a late or unscheduled delivery is an inconvenience rather than a safety or operational risk.
