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2019年加拿大基础设施报告卡，加拿大人每天依赖的大部分基础设施已经使用了20多年。据报告，相当数量的市政基础设施状况很差或非常差。因此，不断监测结构安全并在需要时立即进行修复或更换是很重要的。现有结构和新结构的结构健康监测（SHM）就是这样一种工具，它对于确定结构在地震等任何事件发生前后的安全使用寿命至关重要。这项建议是由古普塔博士提出的，他领导着维多利亚大学（UVic）创新材料和基础设施监测设施（FIMIM）。这项提议是应萨尼奇地区的要求提出的。此次合作的目标是对Mount Tolmie上一个已有50多年历史的水库进行状态评估和SHM。根据该区提供的资料，该水库建于1966年，并于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。在这个试点项目中，实时监控还将补充现有的维护协议，并协助城市工作人员在未来的维修和维护方面做出明智的决定。Saanich地区和UVic之间的这个试点项目可能会在加拿大的其他水库和基础设施中推广类似的SHM应用。
