Chapter 3 - Interoperability

Interoperability is the ability that allows different systems to communicate with one another. This software and application ability is essential in moving towards a more automated future. The BIM handbook explains that utilizing interoperability can lead to a multitude of benefits. If software and applications used in design feature the ability to communicate with one another, manual copying of partial project data will be minimized. This feature can possibly lead to more consistent results as well as save engineers valuable time. Interoperability leads to more automation which then leads to less time spent performing tedious task such as copying project data to another piece of software. (Eastman 2011) If the data exchange between software were to become more advanced and accurate, more efficient building designs could be determined as well through the use of tools such as Revit MEP-IES<VE>.(Kumar 2008) The cost of inadequate interoperability in current systems is astronomical and is estimated to cost United States industries nearly $16 billion a year.(GCR 2004) While other industries such as medicine utilize this technology, BIM is a technology that heavy relies on communication between numerous applications. 

With respect to software, interoperability is achieved through programs, such as AutoCAD and GIS, being capable of using the same file formats and exchange data through those formats. As Audrey mention in her post, there are three categories of data exchange utilized by BIM. These are platform-to-tool, tool-to-tool, and platform-to-platform. (Eastman 2011) Platform-to-tool is the most common and important data exchange according to the BIM handbook. An example of this would be defining a model utilizing a BIM platform and then translating that model to a tool that would perform certain task such as structural analysis. This type of exchange is extremely difficult and has not incorporated much automation however. Engineers must use data acquired from this exchange with sound judgment as the data may not be correct. With future innovation in BIM, these different categories may be able to become completely automated and allow engineers to focus on other tasks. 

The current state of interoperability is very shallow. While interoperability does exist with BIM products, it is very limited. Anyone who has tried to exchange models through multiple BIM products can identify with issues plaguing this feature. A big issue being seen today is version compatibility. Due to software upgrades being release continuously, linking several applications together can prove challenging if one piece is out-of-date. Problems also arrive if a project has several consultants. If these consultants do not have the same version as one another, data exchange becomes extremely difficult and fragile. (Burt 2009)

Interoperability is an extremely useful capability. However, in the current state, it can be more of a nuisance due to compatibility issues. This communicating ability will no doubt become more advanced in the near future and will allow engineers to obtain data more effectively and produce better products.
