Conflicts during the construction process is very common, therefore, there contractors that draft contracts in order to prevent conflicts from happening between all or some of the parties involved in the construction process. Furthermore, there is the issue of time and money. Chapter 6 discussed why and how BIM is important and can be of a great help in the above mentioned areas. Furthermore, it explained it's importance and its benefits. However, as the world become more dependent on computers and softwares to do a number of tasks, until now there is no BIM software that can successfully help deliver all the requirements for a successful implementation like, temporary components, detailed building information, and many other requirements all together. Therefore, it's only fit to create a model that comprise all the different tools, and perhaps be able to identify major/complex conflicts.

If we were to compare previous BIMs to the current one, one would clearly realize how it improved under a very short time.Today, contractors find BIM very advantageous during the bidding stage of any project, because it helps them model something and show it to owners. BIM can also be utilized by contractors to estimate the final cost of a project once the full scope of work is given. Section 6.6 goes into details on how BIM can estimate to some extent a precise final cost. As mentioned in the section, it is ver undesirable to wait until the final project is delivered to see how much it costs. Therefore, estimators can use the different BIM tools to give project owners a more precise estimation of the final cost and quantity takeoff. However, it is worth noting that currently no BIM tool provides a full capability of a spreadsheet or an estimating package. But, there are methods that helps with the estimating process that estimators can use like:

1- Export building object quantities to estimating softwares
2- Link the BIM tool directly to the estimating software
3- Use a BIM quantity takeoff tool


Chapter 6 mainly discusses how BIM is a very useful software and can be utilized by most of the parties involved in a project (engineers, subcontractor, architects..etc) and that it helps them share all of the information, and as a result expedite the construction process.
