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多数基础设施都超过20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，必须不断监测结构安全，并在需要时立即进行修复或更换。现有和新结构的结构健康监测（SHM）就是这样一种工具，它对于确定地震等事件前后结构的安全使用寿命至关重要。Gupta博士领导了维多利亚大学（UVic）的创新材料和基础设施监测设施（FIMIM）。这一建议是应萨尼奇区的要求提出的。该合作伙伴关系的目标是对托尔米山一座已有50多年历史的水库进行状况评估和SHM。根据该区提供的资料，该水库建于1966年，并在90年代中期进行了抗震改造。捷运局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，并帮助城市工作人员在未来做出明智的维修和维护决策。 Saanich区和UVic区之间的这个试点项目可能会导致在加拿大其他水库和基础设施中类似的SHM应用。
