BIM is a very useful tool, but there are a few drawbacks with it in the industry. One issue is that not everyone is proficient with BIM or even familiar with it. This causes issues with what direction of modeling the owner and his clients want to go with. Everyone needs to be on the same page with BIM because although it can save a lot of money, it can cost a lot of money as well if it is not used properly. If a company does not have the software, or the skilled workers to do the job, it will cost a lot more money. A lot of times, they will have "to hire a BIM manager" which would increase the budgets. For the company I work for now, not everyone in the company is familiar with Revit. There is about 5 people in the company that know how to proficiently use Revit, and all of those people are young engineers. I am actually one of the workers that is designated to work on Revit projects.
Revit projects are also not very useful for smaller projects because it requires a lot of detail and time which would be unnecessary for a small project. Another issue is the contractor demands. If the contractor only wants 2D drawings, then BIM would be a waste of money. BIM is very useful for modeling buildings, and showing isometric views of the building and its sections. If the contractor only wants 2D, then programs like AutoCAD would be more beneficial since a lot of companies are proficient with it. In my opinion, AutoCAD projects are still going to be very popular in the next 10 years or so due to the all of the companies that have not adjusted to BIM. Once project managers and higher level engineers become proficient with BIM, I think BIM will take a huge jump in the industry.
A problem with Revit that I often run into is synchronizing. If a lot of engineers are on the model, or if the model has a lot of data in it, the software will take between 5-10 minutes to load. If the model is not synchronized periodically and there is an outage, the model will lose all of the progress since the last synchronization. I have been in this situation. I once was in the zone, and I kept ignoring the synchronization updates, and then I, as well as other employees, lost at least a hour and a half worth of work. That work would have to be repeated, which would cost money. One more issue I have with Revit is a central model cannot be opened in different versions which is frustrating. If other companies aren't updated with the same software, then there will be issues with linking in models etc. Also I grew accustomed to Revit 2019 & 2020, so when I have to work on a project in Revit 2018, I get frustrated due to the lack of advancements. Revit families, however, can be brought in from earlier versions which does make life easy. Revit families are very important in making a proficient building model.

Michael,
I definitely agree that simulations and virtual reality will become very popular and very useful in the future. I also thought your statement about the possibility of changing aspects of the building systems in the 3D realm. For example, it would be extremely useful to be able to change a duct size or move mechanical systems around if I notice something that should not be there. I agree that having a 3D version of the building would be very useful when selling a building. It would clear up many questions that clients, engineers, contractors often have when they first get the project.

Dane,
I agree with your standpoint that a lot of companies still like to use AutoCAD because of the familiarity and the fact that there most drawings that go out to the contractors are all 2D. Therefore, some companies do not think there is a need to adapt. However, over time I think Revit and other BIM software will ultimately take over as the dominate design softwares. I think the main thing that will make companies adapt to the BIM industry is the ability for multiple people to work on the project model at the same time. AutoCAD only lets one user make changes to a drawing at a time which limits productivity if multiple people need to be on the file.

It is so beneficial that 2D linework appears to 3D in every view. I agree that Revit is better for presentation. It allows for 3D views, sections, and elevations without having to draft those views individually. One of my favorite aspects of Revit is the ability to look at in section, and be able to adjust the model through the sections. In my co-op, I have to draft piping and ductwork, and the sections are a lot easier to understand the situation as well as adjust the model. Communication is also a huge benefit from BIM with its synchronization capabilities, and its 3D features.

Stephen,
I remember having issues in AutoCAD where the model would take several minutes to load and will often be an un-updated file. We also had to run files through a converter sometimes if the format was from an older version of AutoCAD. Synchronization issues are truly annoying and cost time and money to fix. If there was a way to make the files "smarter," such as saving automatically after a certain period of time or being able to match versions with another, it would be a lifesaver.
