TRIUMF is Canada's National Laboratory for Particle and Nuclear Physics located on the University of British Columbia campus. TRIUMF’s Advanced Rare Isotope Laboratory (ARIEL) expands Canada's capabilities to produce and study isotopes for physics and medicine.

This complex laboratory, located on the University of British Columbia campus, has a concrete structure and a steel roof that accommodates a four-storey Target Hall.

The challenge put to the team was to develop a solution that minimizes differential settlement while providing a shield from the radioactive material. Working in close collaboration with Chernoff Thompson Architects, Bush Bohlman responded by devising a large raft solution. It consists of a mass concrete raft slab and wall elements up to 1.2 metres thick for both strength and radiation shielding. Overall, the facility contains more than 5000 cubic metres of concrete.

A tunnel connects the main facility to the existing Accelerator Building, which accommodates a renovated Electron Hall laboratory area containing massive cast-in-place concrete block elements. Auxiliary buildings to the main facility include three steel structures—including the two-storey Stores Building—a two-storey Compressor Building with bike facilities, and a single-storey Badge Building that is designed as a movable structure.

By providing a viable solution to a complex problem, Bush Bohlman was integral in bringing this important research and production laboratory to life.
