Okland’s largest project to break ground in 2025 was West Valley Hospital in West Valley City, Utah. With $2.25 billion in reported revenue, up from $1.76 billion the previous year, the contractor was ranked No. 5 on ENR’s 2026 Mountain States & Southwest Top Contractors list.

Sixty-eight firms shared their revenue, key sectors and top projects with ENR as part of the magazine’s annual survey. Rankings and sector breakouts begin on page MSSW12 of this issue.

The region’s fastest growing sector is data centers. “The market was valued at $270 billion in 2025 and is projected to grow to almost $700 billion by 2034,” says Cris Bryant, executive vice president of Layton Construction’s national health care business unit. However, some of the biggest impacts of that growth aren’t the data centers themselves but the ripple effect they are creating, he contends.

“These massive projects, often with workers numbering in the thousands, ignite a larger demand that all our other commercial sectors follow,” he says. “And while this varies by location, in New Mexico, for example, we’re seeing a real uptick in higher education.”

Layton will soon break ground on the University of New Mexico Medical School Campus expansion in Albuquerque, and Bryant estimates the 330,000-sq-ft mass timber facility will have a local economic impact of $1.5 billion.

Layton’s largest project to break ground last year was the $600-million St. Vincent Regional Hospital in Billings, Mont. These and other community-focused projects helped the contractor maintain its standing in the No. 1 spot on this year’s ranking. Layton reported $3.09 billion in revenue for 2025.

Amenities include ground-floor retail, co-working space, a dog run, community garden, wine lockers, a fitness center, yoga deck and a resort-style pool and sundeck.

Health care demands are driving growth across Colorado as well. While Layton’s work with CommonSpirit is geared toward orthopedic offices, AdventHealth is focused on building health care in Colorado’s more rural communities.

“Health systems throughout Colorado and the broader region are investing in expansions, renovations and new facilities to serve growing populations and evolving patient needs,” says Scott Miller, Mountain States business unit leader for DPR. “We’re seeing that firsthand on Denver metro area projects like the Craig Hospital vertical expansion in Englewood, AdventHealth’s new patient tower in Parker and CommonSpirit’s St. Anthony South Denver medical campus in the Meridian community.

“At the same time, advanced technology work—particularly data centers, aerospace and mission critical facilities—is accelerating as AI and digital infrastructure demand drive significant investment,” Miller adds.

DPR was ranked No. 15 on this year’s regional list with $969 million in reported revenue.

For Broomfield, Colo.-based Hensel Phelps, aviation continues to be a major regional driver, and the contractor has significant projects in Denver and Boise. Charlie Robben, regional vice president, says the region’s growth is also tied to data centers, federal programs and water infrastructure as communities continue to invest in critical facilities and services.

Hensel Phelps took the No. 9 spot on this year’s list, with $2 billion in reported revenue. The firm’s largest project to break ground in 2025 was the $277-million Douglas Commercial Land Port of Entry in Douglas, Ariz.

Hensel Phelps is investing in technology and data-driven decision-making to improve planning, coordination and project execution, Robben says. “Owners continue to look for greater certainty around cost, schedule and risk, which is driving more interest in collaborative delivery methods and earlier contractor involvement,” he notes.

“As the industry shifts from prioritizing speed to prioritizing certainty in construction, owners want confidence in budgets, schedules and outcomes, particularly on occupied health care campuses and other complex facilities,” adds DPR’s Miller.

To meet those expectations, DPR is leaning heavily into self-perform work, prefabrication, virtual design and construction, digital twins, reality capture and data-driven coordination. “As projects become more technical, especially in health care and advanced technology projects, those tools allow us to solve challenges earlier and deliver more reliable outcomes for our clients. Owners will remain disciplined and selective, placing a premium on partners who can reduce risk and provide predictability. The firms that succeed will be those that combine technical expertise, workforce strength and early collaboration to deliver certainty in an increasingly complex environment,” says Miller.

Adds Robben: “There is still plenty of work available, but owners are being more deliberate about where they invest and who they choose to partner with. The firms that understand their clients, know their local markets and consistently deliver cost and schedule certainty will continue to separate themselves from the field.”
