Radiation Oncology Addition
HCA | Portsmouth Regional Hospital | Radiation Oncology Addition | Portsmouth, NH
After conducting multiple projects on the Portsmouth Regional Hospital campus, DPR Construction was engaged to execute a ground-up expansion for the hospital. This addition supports the hospital’s radiation oncology services, with construction wrapping around the Southeast corner of the existing Hospital.

Project Features
The project included a Linear Accelerator vault, a CT Simulator room, and a High Dose Rate (HDR) Brachytherapy vault. Additionally, there are two separate waiting rooms, along with exam rooms, a nurse’s station, a reading room and other support spaces. A new drop-off canopy was also added for the extended radiation department entrance, and a new prefabricated canopy was installed over-top of a mobile MRI concrete pad. Lastly, a second-floor penthouse was required for the new mechanical equipment.
Coordination of the LINAC Vault
The concrete LINAC vault was designed to have walls up to 7’-6” thick and a roof thickness of up to 5’-6” in some locations. Micropiles were drilled in the heart of winter to support the 10’ deep vault foundation and the rest of the expansion. A quarter of this expansion was located on the edge of an existing wetland which resulted in significant de-watering challenges throughout the foundation part of the project. The on-site team used a combination of sheetpiles drilled along the border of our scope along with 24/7 de-watering pumps to divert the water.
The new CT Simulator room was constructed with lead lined walls and was built directly adjacent to the existing MRI room. The MRI remained operational throughout our project and the team prioritized safety by installing and maintaining the required copper protection at this pinch point. There were ultimately no issues with our project or the facility’s MRI operations.
Both of these complex installations required constant coordination between the out-of-state design team and vendors (Varian & GE Healthcare). The project teams started this coordination early in the project, before construction, to work through discrepancies between the drawing sets and to get clarity with the subcontractors on how the scopes would be built in the field. This thorough collaboration between the key parties proved to be a critical risk mitigation technique for the project. It ultimately led to an efficient install that saved time and money.
Collaboration with Campus Facilities
The same DPR Construction team remained on campus for over eight projects, creating strong relationships and collaboration with campus facilities, department leads and local Portsmouth inspectors. This continuity remained key during the occupied expansion. DPR Construction also provided construction management services for the following projects on the Portsmouth Regional Hospital campus:
- ICU/Med Surg Expansion & Renovation
- ICU Buildout
- Interventional Radiology Room #1 Renovation
- Maternity Headwall Replacement
- Water Repair Damages
- Interventional Radiology Room #2 Renovation
- Culvert Replacement
- Proximity Cabinet Install
