The design of healthcare spaces can have significant impacts on the psychological and emotional well-being of patients and healthcare providers. Thoughtfully designed spaces can reduce stress and anxiety, improve patient satisfaction and even contribute to faster recovery times. Elements such as natural lighting, calming colors and ergonomic furniture are essential to a healing environment. In imaging suites, where patients may experience anxiety about procedures, design elements that promote a sense of calm and reassurance can make a significant difference.

As medical technologies continue to advance, the flexibility and adaptability of the design become paramount. Spaces that can easily accommodate new equipment and evolving healthcare practices ensure that facilities remain at the cutting edge of medical care without requiring frequent and costly renovations. This forward-thinking approach is integral to maintaining high standards of patient care and operational effectiveness over time.

The Challenge in Action

The University of Iowa Hospitals & Clinics (UIHC) is a public teaching hospital and Level 1 trauma center. In addition to its clinical work, the hospital also serves as a major educational hub, training future medical professionals, and is also one of the largest healthcare providers in the state of Iowa. RDG has been a key partner in UIHC’s ongoing efforts to enhance its facilities, with collaborations that span various projects, including the recent replacement of MRI and PET/CT machines within the Pomerantz Family Pavilion. These projects are part of a broader initiative to integrate cutting-edge medical technologies into UIHC’s existing infrastructure, ensuring that the hospital remains at the forefront of medical care. These projects required managing accelerated construction schedules, addressing existing conditions and ensuring uninterrupted hospital operations. Let’s look at each more closely.

Case Study 1: MRI Replacement

Feasibility

The MRI replacement project was situated on the lower level of the Pomerantz Family Pavilion within the Radiation Oncology department. The initial step involved assessing the infrastructure needs, where it was determined that the MRI machine required support from the campus's chilled water system and a dedicated backup. Additionally, a Variable Air Volume (VAV) system was necessary for the scanner room to accommodate current and future equipment, as humidity requirements have become increasingly stringent with advancements in imaging technology. The project also included updates to finishes, lighting and telecom systems to align with current UIHC standards.

A significant challenge was rerouting the quench vent from the lower level to the roof, covering a 120-foot distance through multiple active departments. Working closely with equipment providers and engineers, our design team devised a cost-effective solution by placing the vent inside the healing garden one floor above. This unconventional approach saved over $75,000 in labor and materials, avoided disruptions to active departments and ensured the hospital could maintain secure and safe access for future maintenance.

Planning the Plan

With the feasibility study complete, we transitioned to the design phase, prioritizing the accelerated construction schedule driven by the urgency of ongoing research and clinical operations. Removing the old MRI, infrastructure updates and installation of the new machine needed to be completed within approximately 100 days. The design team proactively engaged with trade partners to understand lead times, especially given the uncertainties of the COVID-19 pandemic impacting supply chains. We crafted a detailed construction schedule and included language in the bidding documents requiring contractors to have all necessary materials on hand before starting on-site work. Additionally, we collaborated with the owner to implement incentives for contractors to reduce the construction timeline by offering higher payouts for each week saved.

Execution

During execution, our team efficiently decommissioned the old MRI machine and addressed existing conditions. We maintained focus on responsiveness, providing solutions to contractor inquiries within days to keep the project on track.

By adhering to a well-structured plan and remaining adaptive, we completed the MRI replacement project within the anticipated schedule, minimizing disruptions and enhancing the facility’s capabilities.
