One of only 12 proton-therapy cancer centers nationwide, this facility is the first delivered using design-build. The team says the method enabled it to complete the $54-million project on time and under budget. The fortified two-story building is stocked with an array of high-tech medical, structural, mechanical, electrical and plumbing systems. Surrounding the equipment are concrete walls up to 21 ft thick to prevent stray radiation from escaping.
