Productivity Analysis of Lateral CIPP Rehabilitation Process Using Simphony Simulation Modeling

Abstract

One of the challenges of the construction planning stage is selecting an appropriate construction setup, such as crew and equipment conformation, for a project. It is essential to choose a suitable method that can save time and avoid significant disruptions in the area, especially for projects in urban settings. Management must consider various resource (crew and equipment) combinations, calculate the associated time and construction productivity for each scenario, and determine the most desirable solution. In this research, a simulation-based approach was used to assist decision makers in choosing the best crew and equipment combination for lateral rehabilitation using cured-in-place pipe (CIPP) from the main line, also called lateral relining process using main and lateral cured-in-place liner (MLCIPL). The simulation model enables users to simulate for different resource compositions and calculate resource utilization and total duration of the project. The results’ comparison is demonstrated in this paper. This paper also suggests an amendment in the installation sequence to improve the construction productivity, which was developed from the results of this model.
