Problems identification in an earthen dam construction by computer simulation

Abstract

Any construction work is influenced by some internal and external factors. There are several examples of projects which have failed and some which were inefficient due to miss management. The performance of construction work depends on the methodology used to overcome the problems. Several methods are available to identify and resolve the problems. In Bangladesh conventionally the construction operation is done manually and it is critical to predict the problems. Simulation is a new approach to find out construction related problems it is both convenient and realistic. It is also an inexpensive, fast, and flexible method. Simulation is conducted by simulator and activity based simulator are used to simulate a construction system. Using simulation, a model can be developed in a virtual platform and it can then be tested with varying input parameters and resources. Simulation technique may help in making proper decisions by identifying the problems; this can be an important tool for project management. As a reverie country many earthen dams are constructed every year in Bangladesh. Several projects have failed and some were inefficient due to problems of construction. Simulation techniques are one of the best solutions for identifying such. Simulation has been performed for the major activities of a project which have a significant effect on the earthen dam construction. The major problems of the construction site were identified from real life construction projects. The effects of the problems were correlated with environmental effect using the computer simulation technique. An earthen dam construction database has been used were identified the major problems which have a significant effect on time and efficiency of the project. MS VISIO and construction simulator Stroboscope has been used for simulation and analysis. Minimizing the problems and optimizing input resources has been identified as the best technique of an earthen dam construction operation. Thus needs to be taken in to account in project work to be taken in the future.
