| Abstract | The Municipal Infrastructure Investment Planning (MIIP) project is a four-year collaborative project between the Institute for Research in Construction, six Canadian cities, three regional municipalities and the Department of National Defence. One of the project deliverables is research in the area of social costs. The main objective of this client report is to establish a general procedure to quantify user components of social costs related to municipal infrastructure rehabilitation and constructionprojects. User costs include travel delay costs, vehicle operating and maintenance costs, and cost of accidents. Existing user costs quantification models are identified and modified where necessary to represent Canadian urban environment.The proposed methodology is applied to actual infrastructure rehabilitation and construction projects carried out in the City of Regina, Saskatchewan, Canada in summer 2006. It is identified that travel delay costs represent a major part of project's user costs. Effective mitigation strategies are proposed as a result of this research. These include scheduling work for off-peak hours such as evenings and weekends; clear and accurate marking of work zone and detours; coordinating with other work in close proximity; detours through industrial instead of residential areas. |
