In the digital world, patterns or standards allow people to create, use and keep information in a very organized way. The standards not only lead to better practices but also offer means to obtain and measures improvements. Changing information about design, construction, models, specifications, and spreadsheets in a consistent and consensual way can reduce costs and waste. In order to reach this, the design team members need to be able to work together more effectively than before.
The following processes are critical for the modern design coordination in BIM:
1) Coordinating the design in a way that allows everyone to have the latest version of the necessary information to do their tasks.
2) Communicating everyone as soon as possible when a problem is detected, before it “contaminates” the design and jeopardizes the work.
3) Reducing duplication of effort and rework by communicating decisions or analyses to the whole design team.
A Indústria da Construção precisa se proteger da perda de informação e começar a reunir, produzir, submeter e recuperar informações digitalmente.
The Construction Industry needs to protect itself from the loss of information and start collecting, producing, submitting, and recovering information digitally.
In the emerging BIM universe, the content needs to be:
In order to obtain all this, we need to understand why standardized information and processes are necessary.
A few items to consider
Where is your information kept and how is its backup done?
At a certain point of the building’s life cycle, its facilities and components will require change, update, and maintenance. If you know where to find the relevant information about the components, you will quickly save time, Money, and avoid frustration.
Who owns the data?
This specific question will be backed by contractual documents. You have to ensure that everyone in the design team, including the client, knows what the data represents and if it is confidential.
For example, the data from a military facility, a jail, or a bank might not be available for obvious reasons.
Who has access to the information?
Although not all members of the design team have access to all the information details, the information they need must be available so that they contribute to a successful collaborative environment.
How can you control access? Can anyone do this?
Not everyone needs to write and read data. In many cases, a simple version of data reading, with no permission for editing, is adequate and enough.
The opposite of “interoperability” (open) is “owner” (closed). Consultants and professional sometimes use the word “native” more than “owner”. A “owner” data format, which is specific of software makers, can be adapted for a market in constant change more quickly and more efficiently. In the long term, though, such format is expensive to keep. You must be able to change data, no matter which software it comes from; this is BIM’s deepest essence, its ethos.
Going in the right direction: openBIM
openBIM is a initiative from buildingSMART and many companies that are leaders in the software market. It’s a universal approach not only for design collaboration but also for delivery of buildings, operation and maintenance of the assets, which are based on open patterns and pre-established workflows.
openBIM is more than IFC. It’s a commitment to the open patterns and an engagement with everything that is involved with a building during its life cycle.
Being a data scheme, IFC alone can’t provide any interoperability; it’s based on the interfaces that different software produce among themselves.
The discussion about the IFC scheme sometimes produces critics and debates over data omission or geometry loss, but let’s think of something: is this because of the IFC pattern or because of how the IFC scheme is implemented in a specific platform?
There are restrictions in the IFC’s abilities to contain parametric information and manipulate the size of objects. However, IFC Release 4 (IFC 4) and its subsequent versions will be more and more improved.
Nowadays, most of the modern software support the import and export of IFC data model. buildingSMART is the certifying entity that submits the software to tests ang gives them the “IFC compatible” degree. This information flow is critical for the collaboration and interoperability because it allows the information exchange between software of different makers.
buildingSMART and software makers have designed openBIM around fundamental principles to encourage the benefits of interoperabilty
1) No matter what software the teams are working on, you can participate and collaborate too. buildingSMART calls this “open and transparent workflow”.
2) The goal is that the Construction Industry can use a common language with clients and commercial and supply teams during the hiring process, making comparisons and equalization of compatible prices more quickly and with better data quality. The software versions and updates can’t cause problems in your design because they are all interoperable.
3) By using open formats and the standards, openBIM also helps the design team use the design’s data for a much longer time. If the life cycle of a software for assets of management facilities can use the same data formats, the duplication of data and the entry of mistakes can be avoided.
If you are a designer, consultant, or supplier, you can join the workflow without worrying about the BIM tools that you use. If all the designs are open, nobody can be excluded based only on the software platform.
