For Justin Adams, senior project manager at McCarthy Building Cos., executing the 330,000-square-foot expansion at Mayo Clinic’s North Phoenix campus “was honestly one of the most amazing projects and experiences I’ve had in my career. career. That was different.”
The expansion, carried out using an integrated project delivery approach, required the expansion of three areas, including 60,000 square feet of added hospital space and 20,000 square feet for three new operating theaters, as well as new shell space and clean supply spaces. However, it was the vertical clinic expansion of approximately 250,000 square meters that pushed the challenges to another level, requiring the removal of the existing ceiling, while protecting the floors below where the cancer patients were receiving treatment With the building bounded by existing structures on three sides, vibration control was a primary concern. Rather than risk using potentially disruptive hard connections to link new and existing structures, the team designed a 1,473 linear foot expansion joint system to minimize vibration risks. A unified curtain wall system was also chosen which minimized disruption to existing facilities and accelerated construction.
Adams attributes the timely completion of the project, in just 18 months, with minimal items on the checklist remaining at the end, he says, to the collaboration between the diverse group of stakeholders that began to come together a year before construction began. The collaboration, and the end results, was that more than 70% of the project’s business partners took on design support roles.
