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.

根据加拿大基础设施报告卡2019年，加拿大每天依赖的大多数基础设施都超过20年。据报道，有关市政基础设施的数量较差或状况很差。结果，重要的是要在需要时不断监视结构安全并立即进行康复或更换。现有结构和新结构的结构性健康监测（SHM）就是这样的工具，对于确定预期结构的安全使用寿命至关重要，例如地震等任何事件。该提案是由古普塔（Gupta）博士制定的，他领导维多利亚大学（UVIC）的创新材料和基础设施监测设施（FIMIM）。该提议是根据Saanich特区的要求。这种伙伴关系的目的是在托尔米山上的50岁以上水库上进行条件评估和SHM。根据该地区提供的信息，该水库建于1966年，并在90年代中期进行了地震改造。该地区希望为该结构开发基线，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，实时监控还将补充当前的维护协议，并帮助市工作人员做出有关将来维修和维护的明智决定。 Saanich和UVIC区之间的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。
