Benefits of Maintenance and Rehabilitation
To develop an accurate understanding of the relationship of proper maintenance and rehabilitation practices to the life expectancy of infrastructure.
In the next decade, Canadian municipalities and CIS, owners and operators will have access to improved practices and strategies for the maintenance and rehabilitation of their infrastructure. The benefit will be the extension of the useful life of CIS. In addition, a better understanding of the factors affecting service life will improve the ability of owners and operators to evaluate new technologies for the renewal and rehabilitation of their infrastructure assets.

• Service life of infrastructure is affected by many factors over a long time span, complicating an economic analysis. Factors include: • materials; • installation procedures; • environment; • maintenance; and • service loads. • CIS are often difficult to inspect due to access problems and continuous utilization. • Management and rehabilitation practices vary greatly among CIS owners and operators. • There is a lack of historical performance data for underground systems, and there are problems with predictive model validation. • Performance indicators for determining the condition of CIS are not widely available, and when they exist are seldom used. | • Identify and characterize the key factors that influence the longevity of infrastructure, including: • quantification of improvements due to interventions such as repair, maintenance and rehabilitation; and • acceleration of deterioration due to breaks or failures. • Predictive models for the residual life of infrastructure that support asset management and decision-making • Performance indicators that are relevant, reliable, easy to measure and widely used
