This chapter went into how BIM
could be used by contractors and the benefits and advantages this kind of
software presents. One section of this chapter that I found most interesting was
section 6.12 BIM In the Field. This section discusses the types of applications
for which utilizing BIM software would be advantageous in the field. It goes
into the use of BIM for Augmented Reality which I have had experience with in
my professional work from a design engineer standpoint. Not only is this a great
tool from a contractor standpoint for in the field clash mitigation and
planning it can also be used as a tool for client presentations. This can prove
to be a real selling point for clients when they get to actually see a modeled
version of their building sitting in front of them. I also thought that from a construction
stand point, getting to see where ducts and pipes are going to be put before
the work is done does a great job at reducing the mistakes and catching errors
before they become an issue.
Another
interesting portion of this chapter was the us of BIM software for estimating
and scheduling which is an aspect where I believe there is a high level of
disconnect between contractors and the design team. In a IPD design process
where contractors are brought in early in the process and utilize proper BIM
tools, the estimating and scheduling process can be done much more officially. In
lieu of hand counting and recounting as design changes are made, counts are
able to be easily exported from model data and can be updated much more efficiently
as design changes are made. I do however, also appreciate the acknowledgement
of the initial high costs of firms implementing these processes with this kind of
software as it requires a large overhaul and licensing purchases. This is a
real concern and should be properly taken into consideration.
Implementing
the use of BIM software by contractors provides a much more efficient construction
process with less error which altogether leads to lower cost.

I also like BIM software's ability to spot mistakes in design. You brought up a really interesting use of this technology in spotting errors from a code perspective. I think its also interesting how this software can be used to mitigate errors and discover mistakes from a coordination perspective. In a 3D model environment as opposed to a 2D environment, every piece contains information and its unique, not just lines. This allows say mechanical equipment the mechanical engineer draws to show up on the Electrical engineer's plans so that it can be powered properly without having to copy and paste everything. This reduces the oversights caused by design changes not being properly communicated throughout the team. BIM also helps with clash detection and improving the actual constructability of the project.

Reading the chapters of this book made me realize that the company that I work at is only barely using Revit for all of the capabilities that BIM software possesses and this is because of how difficult it is to completely revamp the methods that people have become accustomed to. Right now my company is still very much using BIM software in a 2D manner and not fully embracing the capabilities the software presents and I'm hoping that armed with this knowledge I can go back to them and push a little harder for them to start utilizing it properly.

I'm glad I read this post as one of my ones to comment on because I wasn't quite sure what this topic was. Now I understand it a lot better and can relate to it having experienced a lot of these problems. Whether it was due to a broken link because a file was moved or a slow compromised server causing issues for modeling.

Hey Andre,
Quite the interesting post you have here. The augmented reality, in particular, has piqued my interest. The fact, as you said, allows the client to really see the product the team is designing can really pay off in the long run. Say that the client had something totally different in mind, and when they were shown the sample in augmented reality, they'd be able to convey their likes and dislikes hopefully before any real damage is done. Or you can take the other side of the coin and perhaps have a client that is wishy-washy in what they want, and when they finally see your design in virtual completion, it could sway them in committing to your team's vision. Overall, like you, I know this tool as a way t increases the efficacy of your team's time as well as the overall experience for the client.
Andre, I appreciate that you discuss the high costs and initial funds needed to integrate these kinds of technological processes into corporations. so often, costs are overlooked for the shiny and bright future of technology and we can’t forget that for smaller firms, these upgrades require massive capital, that can oftentimes be hard to obtain.
