Abstract

The importance of good construction planning affects the final costs of the production and the timing of the project. Planning for building projects has been studied with the aim of identifying how three week planning appears in the construction industry today.

A case study has been conducted in Navisworks Simulate to assess whether the software is suitable to connect the task schedule with the BIM model to create a 4D model. 4D models are used for performing 4D construction simulation to visualize the project. In order to use the benefits of the model, investment in equipment and software is required. This means higher costs for the companies. Therefore inexpensive software is needed so that it will be profitable to use 4D

models even in the production of small projects.

The survey which aims to identify planning in the construction industry shows that planning varies between the different sectors, but also that planning technique depends on the knowledge of those who actually carry out the planning. The conclusion is that education in planning techniques and computer aided planning tools is needed to implement BIM in the planning process. With a detailed schedule and a BIM model which is adjusted to the construction of the building, Navisworks Simulate is a suitable program to use in the creation of

Building Information Models. When using Navisworks Simulate to create a 4D model, the natural choice would be Navisworks Freedom software for visualization of the project in the production. This is because the Navisworks creates its own file format, which can only be opened in software created by Autodesk.

This study was aimed to improve three week planning and increase the use of assimilating feedback by using BIM in the construction industry. The conclusion is that the choice of software for the creation of a 4D model affects the application that later can be used for visualization.
