According to Canadian Infrastructure report card 2019, a majority of the infrastructure that Canadian's rely on every day is more than 20 years old. A concerning amount of municipal infrastructure is reported to be in poor or very poor condition. As a result, it is important to constantly monitor structural safety and conduct immediate rehabilitation or replacement when needed. Structural health monitoring (SHM) of existing and new structures is one such tool that can be vital for determining the safe service life of a structure pre and post any events such as an earthquake. This proposal has been developed by Dr. Gupta who leads the Facility for Innovative Materials and Infrastructure Monitoring (FIMIM) at the University of Victoria (UVic). This proposal is in response to a request from the District of Saanich. The goal of this partnership is to perform condition assessment and SHM on a 50+ year old reservoir on Mount Tolmie. According to the information provided by the District, the reservoir was constructed in 1966 and went through a seismic retrofit in the mid-90s. This District would like to develop a baseline for this structure which will be key to determine remaining service life of this structure. In this pilot project, real-time monitoring will also complement the current maintenance protocols in place and assist city staff to make informed decisions about repairs and maintenance in the future. This pilot project between the District of Saanich and UVic can potentially lead to similar applications of SHM at the other reservoirs and infrastructure in Canada.

根据加拿大2019年基础设施成绩单，加拿大人每天依赖的基础设施大多已有20多年的历史。据报道，相当数量的市政基础设施状况不佳或非常糟糕。因此，重要的是不断监测结构安全，并在需要时立即进行修复或更换。现有和新建结构的结构健康监测(SHM)是这样一种工具，它可以在地震等任何事件发生之前和之后确定结构的安全使用寿命。这项建议是由维多利亚大学创新材料和基础设施监测基金(FIMIM)的负责人古普塔博士提出的。这项建议是应萨尼奇区的请求而提出的。这项合作的目标是对托尔米山上一个有50多年历史的水库进行状况评估和SHM。根据该区提供的信息，该水库建于1966年，并在90年代中期进行了抗震改造。该地区希望为该结构制定一个基线，这将是确定该结构剩余使用寿命的关键。在这一试点项目中，实时监控还将补充现有的维护协议，并帮助城市工作人员做出关于未来维修和维护的明智决定。Saanich区和UVic之间的这一试点项目可能会导致SHM在加拿大其他水库和基础设施中的类似应用。
