TRADITIONAL METHODS APLIED IN THE PROJECT PROCES VERSUS USING BUILDING INFORMATION MODELING (CAD VS BIM)

Abstract

Building Information Model or what we call BIM has spread in popularity in the architecture, engineering, and construction industries. Nowadays, BIM is the most promising development in the AEC industries. What is BIM and how does this platform help in the AEC industries? BIM (Building Information Modeling) is a tool that represents the process of development of the planning, design, and construction part of a project. It helps architects, designers and constructors to better understand how their final product will materialize along the way identify and even better minimize the operational problems. The aim of AEC is to achieve better building projects by increasing productivity and quality while at the same time reducing delivery time. In this case, BIM is the program toll that has all the potential to achieve these objectives. In this paper, the knowledge of BIM, the benefits and challenges for the construction industries are discussed. First presented is the main concept of BIM and the possible application in different projects. Then, the role of BIM and its benefits in comparison with the most usable and basic tool, AutoCAD. In the hope of achieving a better comparison, the Stanford University study is taken into consideration by analyzing all the data gathered and collection of BIM and CAD at the same time. After that three case studies are presented to better illustrate the application of BIM in the project and its importance in achieving more productivity and reducing the delivery time. 4 It is followed by an actual project done in Kavaja city by ‘Taulant SHPK’ company referring to its process done in CAD and then comparing it and analyzing it in BIM (Building Information Modeling) tools. The research aims to study the changes in the project when implementing BIM, its importance and how does the project manager's role change in relation to the actors.
