Little Background ?
In early stages BIM was not BIM but it was called a Building Model – BM and also in some regions it was called Virtual Model – VM. The term BIM become popular around 2002 when Autodesk Published its white Paper using the word Building Information Modeling.
So What is BIM basically ?
About BIM you can simply say a process of creation with complete information via specified
procedures, is called BIM.
As we have many procedures available from different Countries and Regions, to which we can choose from. And it will be decided by Client, Designer and/or Consultant.
Then all stakeholders will be notified and properly directed to follow which Standards.
Let’s see Some of the Prominent BIM Standard Procedures;
1- How to Collaborate & Coordinate
For Collaboration and Coordination you will be notified that standard procedures to be followed
and how. Within the given guideline and standards each and every stakeholder will collaborate and coordinate with each and other. These guidelines includes Codifications, Data Arrangement Systems, Data Management System, Data sharing systems and more.
2- Which Platform(s) to be used for Collaboration & Coordination
You will also be notified that how Collaboration & Coordination environment will be established.
That kind of platform Usually called CDE. Here CDE means Common Data Environment.
Two famous CDE’s are “Autodesk BIM360” and “Projecwise”. ACONEX is also used for Data Sharing and management. Guidelines and data management criteria and many other criteria will also be established for usage of CDE and for other correspondence plus data sharing purposes.
3- How much Graphical Information will be Produced
You will also be notified that how much Graphical Information will be produced. Here Graphical Information means a 3D Model. It will be established that how much detailed “3D Model” will be produced using how many stages and using which and how many Software(s). 3D Modeling standards and procedures with examples will be provided for reference.
4- How much non-Graphical Information will be associated
Here non-graphical information means Data. You will be directed that how much non-Graphical
is required to produce for the client. This information is used for Quantifications, Facility management, Construction management, Building lifecycle management and others.
And how this Data of information with be populated within 3D Model and extracted out from 3D Model.
5- Which Platforms to be used for Graphical Information
Here Graphical Information means 3D Model. You will also be informed about platform(s) or software(s) packages to be used for Production of Graphical Information for each and every scope of work and trade such as; Architectural, Structural, MEP, Infraworks and Road works and planning, safety and simulations (Means Construction related Animations). Each and every stakeholder will have to follow described software packages for their scope of work. Some of the platforms or software(s) to achieve the output are; Revit, ArchiCAD, TEKLA, Navisoworks, AutoCAD Civil 3D, Infraworks, Synchro Pro, Allplan, and many others.
6- How cross platform Graphical Information will be shared
You will also be provided with the cross platform graphical information exchange procedure.
Here cross platform means sharing or exchange of 3D Model / Data between non-compatible
and different brand of software(s).
Example of non-compatible software are;
Revit vs TEKLA vs ArchiCAD & 3D Model Production
Navisworks vs Synchro Pro à Planning and Construction Simulation
Civil 3D and Microstation à for Sitework and Roadwork
In every project we have to cope with such a situation, so solutions and precautions are provided and described as per past practices and experience.
These solutions helps us to make project streamlined with smooth work flow.
7- Project Planning and Simulation for Safety & Execution
You will also be provided with codifications, procedure manuals and will be suggested
to use which technology to use, which codes to use and how and when, all of these helps communication easier and better between different stakeholders.
It will also be defined that when to use the information for further processes like animations or simulation of project construction stages, equipment loading / unloading, simulation, installations simulation, simulations for safety, construction and also execution etc.
For example for project planning you will using Primavera, and for 3D Modeling you will use Revit and for construction Animation you will use Navisworks.
So to streamline the process you will follow some same codification to automate the process, as in Revit elements you are assigning some codes to the elements then same codes you will have to use in Primavera. So when you will bring your model to Navisworks then these same codification will help you to Automate the construction simulation or animation and this way you can save the time.
Then further with the help of this simulation or animation you can judge the site conditions and can plan for material arrival, dumping locations, health and safety impacts and can have better predictions toward problems and their solutions.
8- Project stages from Design As-built & Delivery
Under these standards project stages will also be directed to streamline the process. For example it will be directed that under which stage how much information you will feed in the models or in documents and on which stage you will perform other tasks and when and how you will complete the whole process for construction, documentation, as-built and finally, the deliver.
All of these plus other procedures combined together makes BIM a BIM.
