We will walk through SNOLAB is Canada’s deep underground research laboratory, located in Vale’s Creighton mine near Sudbury. The presentation will review the research requirements and describe how these were translated into the design scope for the facility to be located 6,800 feet below ground level. We will walk through the construction challenges and review the strategies to keep this specialized facility on budget in a challenging underground construction environment. Designing for commissioning and operation will be discussed as well as the commissioning requirements.
