University of Ottawa, Advanced Research Complex



We provided acoustics, noise and vibration consulting for a 145,000-square-foot science research facility dedicated to photonics and Earth sciences research. The five-story Advanced Research Complex (ARC) houses classrooms and offices, photonics and nanomanufacturing labs, cleanrooms and a 44-ton accelerator mass spectrometer. Our acoustic, noise and vibration control design included room acoustics, partition analysis, mechanical noise and vibration isolation.

Because this equipment is extremely sensitive to vibration, the ARC has anti-vibration, floating floor slabs that rest on hundreds of micro-piles. We conducted extensive post-construction vibration testing on several levels to verify that the building met the ARC’s strict design criteria.

The $70 million building was funded by the Canada Foundation for Innovation, the Ontario Research Fund and the University of Ottawa. The building reached substantial completion in 2014, with fit-outs of individual floors continuing through 2017.
