The City of Edmonton's Drainage Operations Branch oversees the inspection, maintenance, and repair of the city's drainage network covering an area of over 700 km2 to serve the city's population of over 600,000. The maintenance activities consume a large amount of funding and, therefore, are sensitive to any improvement in the maintenance crews' productivity. This study focuses on the development of improved work methods and engineered productivity standards for selected Branch maintenance crews. The application of the industrial engineering work measurement, lean production theory, and simulation analysis was used to capture current work methods, generate and test alternative methods, and develop the new standards. The focus of this research is to demonstrate the effectiveness of the methodology in enhancing the productivities of sewer maintenance crews by developing and establishing standards utilizing current Work Study Analysis, lean production principles, and simulation.
