Data Exchange

The assigned reading was very helpful to understand the term of interoperability meaning the need of to pass data between applications, and to eliminate the need to replicate data input that has already been generated. Common exchange formats of AEC applications are image formats, 2D vector formats, 3D shape formats, game formats, GIS formats and XML formats. Each of them has different benefits and functions. The important concern is that all the methods of interoperability must deal with the issue of versions. When the applications are updated with new capabilities and versions of standard are not well managed, it creates problems at the process of data exchange. I believe that it is also very important to develop services such as energy analyses of building shells, mechanical equipment simulation, construction and facility management. Even though, each participant is interested in only a subset of the BIM, there is a need for a single integrated database. So that, each participant can review all the systems and sub-systems existing in the structure.

The first article that I read is “Interoperability” written by Stephen R. Ferree. In this article, it is emphasized that there are several reasons why interoperability is very important for building information modeling: it provides reduced installation costs, energy management, improvement of safety and security, and single-seat user interface. It is mentioned that many manufacturers have developed their own protocol to enable their devices to communicate with each other. However, in order to reduce the energy cost, buildings systems must work together to provide the optimum environment for the people and the equipment. Thus, it is very crucial to enable the interoperability between diverse systems within the structure.

The second article that I read is “BIM-Promises and Realities” written by Rita Wong. It is described that BIM is an integrated model that can be used for the design, documentation, coordination and management of a project. However, the author indicates that BIM and other engineering applications have not been as efficient as anticipated due to limitations of interoperability of different software. It is suggested that engineering firms can make use of alternative integration options that operate on various components of buildings.
