Building Information Modeling: A Case Study of a House in Bahria Town, Islamabad

Abstract

The traditional triple constraints of any project are time, cost and scope (Haughey, 2011). However, many construction projects fail to complete within the appropriate time and budget (Haseeb & Aneesa, 2012). Additionally, there has been an increasing emphasis on sustainability over the last few years. These factors have caused several companies to depart from the traditional approach of project management and adopt Building Information Modeling. BIM is a process that involves creating and using an intelligent 3D model to inform and communicate project decisions. Design, visualization, simulation, and collaboration enabled by BIM solutions provide greater clarity for all stakeholders across the project lifecycle. BIM makes it easier to achieve project and business goals. The feature of embedding quantity estimation and time scheduling together with a 3-D model makes it a 5-D model. In addition to the 5D model other technical aspects of BIM includes clash detection and energy analysis. This project involves creating a model of a house in Bahria Town using Autodesk Revit. Quantity estimation, energy analysis and clash detection were performed using Autodesk Quantity Takeoff, Green Building Studio and Navisworks software respectively. The project analyses the suitability of using such tools to improve the construction process.
