St. Luke’s and Layton Construction held a topping out ceremony on June 26 for the Boise Campus Development project. The nine-story hospital tower will add 80 beds and seven operating rooms. Construction began in 2024, with completion expected in late 2029 and patient care starting in early 2030.
St. Luke’s Health System and general contractor Layton Construction marked a construction milestone on June 26, 2026, with a topping out ceremony for the Boise Campus Development project in Boise, Idaho.
Workers, architects, trade partners and St. Luke’s team members gathered to place the final steel beam atop the project’s new hospital tower. The beam carried signatures, written messages and sketches contributed by members of the construction team, continuing a tradition observed on major building projects to mark structural completion.
Dennis Mesaros, vice president for St. Luke’s Boise, McCall and Elmore medical centers, and Jeremy Hobbs, vice president of Layton Construction, both spoke at the event.
Construction on the five-year project began in 2024. Steel framing and insulation work is currently underway on the east side of the site, where approximately 300 workers are active at any given time.
Once finished, the development will connect a new nine-story hospital tower to a six-story medical office plaza spanning 1st Street. A parking garage connected to the plaza was completed in 2021.
Ahead of construction’s conclusion, St. Luke’s has begun transition planning for the move to the new facilities, including coordination with outside planning specialists on equipment relocation, patient transfer logistics and wayfinding signage.
The hospital tower will total 860,000 SF and include a helipad, 80 additional patient beds bringing total capacity to more than 500 beds, seven new operating rooms for a total of 27, and two neuro-interventional biplane imaging systems. The medical office plaza will add 180,000 SF along 1st Street. St. Luke’s owns the project, with Layton Construction serving as general contractor. Completion is expected in late 2029, with patient care beginning in early 2030, according to a St. Luke’s press release dated June 30, 2026.
