As the commercial construction market in Southern Utah—particularly Washington County—continues to heat up, Onset Financial's dazzling new four-story corporate headquarters for its Red Rock Division makes a bullish statement about the company's outlook for the greater St. George area. Indeed, the owner-occupied structure totals 60,000 SF and is designed to harmonize aesthetic appeal with supreme functionality, given that it houses 23 offices, 86 cubicles, myriad state-of-the-art amenities, and a swanky top-floor corporate penthouse for Onset owner Justin Nielsen that is second-to-none. Developed by Salt Lake-based Asilia Investments, CEO Jonathan (Jono) Gardner stated frankly that this project is the nicest, most expensive office project per square foot that his firm has been involved with, and it speaks to Onset's aggressive business practice and optimism in the future of the equipment lending market. "You walk into that building and you know you're in something special," said Gardner. "It's [Onset Founder Justin Nielsen's] way to attract talent. He said, 'This is the way I'm going to build my business,' and he put his money where his mouth is, [wanting] to go above and beyond anything in the market. He leaned into this with an attitude of 'this is my business, this is my operation, I want people to know this is the place to be.’ He has incredible vision and can see things before they happen." Designed by Salt Lake-based Axis Architects and built by Salt Lake-based Okland Construction, the two firms worked harmoniously with each other via a CM/GC delivery method to produce one of the most unique structures imaginable, with a highly-complex layout where two gridlines intersect each other at a specific point in the middle of the building, with the layout based off this one intersection in all directions and floors not situated directly above each other. Gardner charged the design team, led by Pierre Langue, Founder of Axis Architects, to "give us something we've never seen before." In addition to the unique floor layout from floor to floor, they wanted to take advantage of incredible views into Snow Canyon and the environment in general, along with being situated along the Santa Clara River, which offers its own unique aesthetic beauty. Langue pointed out his firm’s perpetual refinement of using "apertures"—a "design element we've been developing and including in our designs for 20 years that is a continuation of an effort instead of one individual design," he said. "It's in reference to a camera—you're inside a box and framing the view. It's a great feature on the inside because you can frame the different views." “That's why the [floor] plates are rotated. It gave us a way to focus the view on something very specific that you want the viewer to see." In addition, said Langue, apertures on the outside are used as an extension of the building and help create shading for the large expanses of glass. Designing the complex floorplate grid was one thing, building it was another. "The layout was difficult because the gridlines were not particular to each other, and they didn't necessarily transfer to the floor above," said Tyler Dehaan, Project Manager for Okland, adding that it's the firm's first project of this kind. He said the "first pier footing we poured was crucial"—it had a column that extended at an angle and only connected to the building at the top floor, and was 15 feet lower in elevation than the first floor. "I was really concerned about that column not being in the right location/elevation and then the steel column not fitting," he added. Dehaan said they wouldn't know for six months if everything would fit—until all the footings, the foundation, three concrete cores (two stair towers, one elevator), and structural steel up to level four were completed. "In the end, it fit perfectly," said Dehaan. "There were no issues." Pouring the three cores was both challenging and labor intensive, and because structural steel tied into the cores, construction on steelwork had to wait until they were built. Okland self-performed the slip-forming process with help from some experienced concrete subcontractors. "When you see what's going on with the structure, you see the genius behind it," said Gardner. "The common cores hold it in place." Another critical and highly unique construction aspect was building a robust “sea wall” along the Santa Clara River capable of withstanding a 150-year flood event. Nielsen had concerns about the building being so close to the river but also wanted a dynamic outdoor terrace with direct access to a bicycle/running path along it. Hydraulic consultants collaborated on a “belt and suspenders” type of decision, said Dehaan, with crews digging down 15 feet below the main floor and installing a retaining wall below the flow line of the river. A wall of riprap and large cobble rocks were installed after the retaining wall was completed and during backfill. A similar build was done along the dry wash on the other side of the site.
