- A system for collecting, archiving, and disseminating lessons learned is a critical component of experienced-based processes, such as the design and construction of roadway and bridges. The construction section of the Kentucky Transportation Center developed a centralized, web-based lessons learned system for the Kentucky Transportation Cabinet. Other state transportation agencies have recognized the importance of formally documenting lessons learned that result from postconstruction and constructability reviews. The cabinet believes it is critical to expand its efforts of capturing lessons learned on all projects and to make that information available to current and future project participants anywhere and at any time. Thus a web-based lessons learned system that can receive text and any form of multimedia data was developed for cabinet personnel, designers, contractors, and other project participants. The project also (a) developed a process for maintaining the lessons learned system that includes the role of a gatekeeper to ensure the quality and accuracy of the submitted and stored lessons and (b) addressed implementation of the system into the cabinet’s project development process.
