The general Robotics article gave a summary of all the different systems used by Robotics and the characteristics that are unique to robotics. The precision with which a robot can perform certain tasks was very interesting, specifically using using a arm with pivots so that it can actually move in six different directions so that actions can be performed at a precise point but also at a specific angle. The different programming systems that robotics use was also interesting because of the different ways the robot takes in information and uses it.
The "Emerging Construction Technology" article was very interesting specifically with respect to Civil Engineering. The article talked about how up until recently we have still been doing construction the same way it was done hundreds of years ago. Recently technology and intelligent systems have started playing a role in the construction world. Much of the pre-construction work can now be performed online such as submitting bids, estimating, and purchasing materials. Other web-based systems can be used to allow the different contractors on a job to make updates which could automatically be seen by the other contractors. I think this is a really important system that needs to be utilized with construction jobs because it would eliminate the possibly of a contractor using out of date plans. With this system the engineer could update a plan or add field sketches to clarify something and the contractor in the field would be able to see these changes immediately and put them into effect.
The article also talks about using intelligent systems to model the projects in 4D where the system uses a 3D model from CAD based software along with simulations of construction to create a model of the construction of the project over time. The goal of using intelligent systems in the construction process is to create a leaner product and ultimately lower the cost of large construction projects. One specific example of how this is being accomplished comes from a European construction company called Dragados y Construcciones, who use a simulation system called PROSIDYC to simulate the casting of large bridge girders, install utility tunnels, and renovate heavy rail systems. This article was very helpful in explaining the ways that construction could become much more efficient through the use of intelligent systems.
I also think its interesting and important to develop a way to update plans in accordance with change orders in a timely manor. My only concern with multiple users on a single document is that it seems like anyone could make changes. i.e. an HVAC engineer could shift a wall 6 inches to better accommodate his design. Such a small change might go unnoticed, but cause a significant structural issue. I guess the layers could be locked so each engineer could only change their relative component.
ReplyDeleteEric, I agree that upgrades need to be made in the construction world. At my last co-op, the contractor we hired used a system called Vela which linked everyone to the same construction documents that they were able to access on either their computer or iPad if they were in the field. Any changes made to construction documents were instantly changed on the main file so there was no having to call one another and make sure that something for the project was done. The only problem with this was that my co-op didn't use the program and still asked for hard copies of construction documents. I guess the point I'm trying to make is that the technology is here and ready to be implemented, it's just a matter of getting people to and use it.
