Building Information Modeling A Case Study of District Headquarter Hospital Mardan

Abstract

During the design stage a construction project is exposed to numerous risks including clashes between Architectural, Structural and MEP designs and poor estimation of quantities and costs. These risks lead to delayed completion and over run costs. In construction project main stakeholders, the contractor and the client wants the project to take least time with cost as less as possible. Building information modeling (BIM) is a solution to these problems which not only detects the clashes but also gives a reliable platform for solution of these clashes before the project execution. Moreover BIM also automatically generates quantities and costs accurately. Along with it, different models can be prepared during the planning phase, which gives detailed visualizations of the project at the very start of the project and all the stakeholders can have a good idea of what the end product would look like. The flow of our project involves creation of 3D model of District Headquarter Hospital Mardan using the tools of Autodesk Revit which included Architectural model, Structural model and MEP model. Later on, this model was used for different kind of analysis. The model was exported to Autodesk Navisworks, which was used for the clash detection of all the three models within themselves and also for the simulation and quantities takeoff of construction activities of the project. Energy analysis was carried out using Autodesk 360 service Green Building Studio.
