WellSpan Cancer Center at Apple Hill Linear Accelerator Replacement

Client: WellSpan
Location: York, PA
Size: 3,872 sf
Dates: 2008–2018

Background: Pennsylvania Community Health

WellSpan Health is a regional health system based in south-central Pennsylvania. CMSI started working with WellSpan in York Hospital in 2005. Since then we have executed over 100 design-build projects in multiple facilities.

Objectives: Linear Accelerator Replacements

To offer the best possible oncology services to their patients, WellSpan recognized the need to provide state-of-the-art equipment in their cancer centers. For over ten years, WellSpan has trusted CMSI to implement equipment replacement projects on schedule, within budget, and with minimal operational disruptions. Since 2010, WellSpan has contracted us to replace four linear accelerators at the Apple Hill Cancer Center.

Approach: Infection Control to Protect Oncology Patients

We carefully coordinated with WellSpan to execute all of the linear accelerator replacements, with special measures taken for infection control. The projects had the potential to be highly disruptive because the vaults were located in the middle of the operational clinical environment. Additionally, these projects included complete removal of the existing concrete floor to install new underground utilities. In this sensitive facility, where oncology patients have compromised immune systems, we implemented specific infectious control procedures to prevent contaminants from entering the clinical environment. We also strategically planned to minimize disruptions such as construction noise, vibrations, and utility interruptions.

Results: New Technology for Better Health

In July of 2018 we successfully replaced WellSpan’s linear accelerators, including the replacement of a Varian 2100 IX with a new Varian Edge. Offering the latest technology such as the Varian Edge enables WellSpan to treat patients with state-of-the-art equipment. The new machine provides more precise treatment, allowing the technician to position the patient in a way that reduces exposure to non-cancerous tissue. WellSpan’s advanced capabilities mean that local oncology patients in York can now receive improved specialty care in their community.


“The staff was impressed with how clean our facility was kept during construction. The construction crew was very accommodating and adapted to our requests, even changing their schedule during construction.”

“This experience during construction was very good. I would like the CMSI team to be involved in our upcoming renovations and equipment replacement for our Ephrata facility.”
