Improvement of Segment Casting in Balance Cantilever Viaduct Using LPS

The project under discussion includes construction of access-controlled Nagpur-Mumbai Super Communication Expressway (Maharashtra Samruddhi Mahamarg) in the state of Maharashtra. The expressway comprises Viaducts, Iconic bridges, Tunnels, etc. The under-construction expressway will reduce the travel time between Nagpur and Mumbai by 4 h as stated by Union transport Minister Shri. Nitin Gadkari. Package-14 of the expressway is awarded to Afcons Infrastructure Ltd. The organization with strategic goals to reduce wastage, improve productivity and better planning is implementing lean construction tools across its project sites. Over the years, lean construction tools have been applied to simple as well as complex construction projects to manage the projects effectively and complete the project in time. In this study, an effort is made to implement the Last Planner System (LPS) for the segment casting activity in viaduct to understand the effectiveness of the system and the impact it has in timely completion of activities. The study shows if all the aspects of LPS are implemented sincerely, the system can help in process improvement which in turn leads to activity time cycle optimization. It also discusses the challenges involved in the implementation of Last Planner system.
