Abstract
  • Over the past two decades, the Lean Construction academic and practicing engineering community has used lean practices and tools to help improve the performance of the Architecture, Engineering, and Construction (AEC) industry. Lean practices have led to improved competitiveness of construction companies that have adopted them, by focusing on ways of maximizing customer value while eliminating waste and improving workflow reliability. In the AEC industry, managers who have implemented lean practices claim that the practices help promote safer projects, on time delivery, and projects delivered within budget. Even though the claims are anecdotal, these benefits are in clear contrast with anecdotal perceptions of projects delivered using other traditional practices. However, to date, lean implementation and risk mapping have not been combined to create risk-informed mitigation solutions in construction management. This dissertation proposes the combination of lean tools and methods with risk management tools to provide new methods for developing risk-informed decision making that can be used to improve office and construction activities in the field of Civil and Construction Engineering. Three manuscripts are presented in this dissertation. The first explores the connection between the application of lean principles and practices and the reduction of safety risks on the job site. The second proposes a new methodology combining risk mapping and lean tools that can help manage and reduce waste in an administrative process in construction. The third and last manuscript proposes a multi-criteria risk mapping solution that combines lean concepts and tools that can help the academic and practicing engineering community understand the onsite dichotomy between reduction of productivity risks and safety risks.
