Building Information Modeling

A Summary









Building Information Modeling is essentially the combination of three elements:

  • 3d Object Based CAD
  • Integrated Practice
  • Digital Construction

3d Object Based CAD

The main distinction of 3d object based CAD is that a model of the building is created electronically. Intelligent objects like walls, doors, floors, beams and columns are placed into a model to represent the components of a building. Previous techniques used graphical lines or 3d shapes to "draw" the building. Plans, sections and elevations are simply created as views of the model.

By using an object model in place of drawing, a great deal of extra information can be produced. As the model can hold data about what each item is, it is possible to automatically create schedules and quantities. Even more data can be attached to each item, and that information can be used at later stages in the project.

Intelligent objects have parameters that can be adjusted, so the model can be produced very rapidly. The accurate representations and the use of 3d allow a greater amount of certainty that the documents actually are correct.





Integrated Practice


Integrated practice is the second component, and essentially it involves sharing a 3d object based model across disciplines and also across software platforms. The transfer of model data across disciplines and software both minimise the amount of wasted effort caused by reproducing the same thing, but also minimises the errors of "chinese whispers" every time a new party transfers information. The result is a more accurate and more efficient process.

Digital Construction

Taking the model data to the next step involves using the information contained to obtain advantage during construction. The model data can be electronically manipulated into many forms and be used to speed manufacture of steelwork, timber frames, reinforcement and other complex components. The model data can also be used for costing and programming exercises and ultimately in asset management.

Conclusions

The construction industry is at varying stages of implementation of this vision. Many companies are still in the infant stages of trialing new methods. Hive Engineering is a leader and innovator in this area, and we have proven experience at successful project delivery using BIM.

If you have any queries, regarding BIM, please contact us, and we would be pleased to discuss it further.


Not so Standard Details


Hive Engineering is able to use our modeling ability to bring to our clients standard engineering details that are clearly and beautifully presented in 3d. Clarity of communication results in less errors and a better product where it matters....on site.

3d Modeling & BIM

Hive Engineering has developed a reputation as a leader in Building Information Modeling. We have successfully been delivering projects for five years in this way.

To achieve this, we have had to develop techniques and software to make the transition, and have had to learn and gain experience at this new way of delivering projects. The reality is that there are many pitfalls, and it pays to have a partner with the experience to deliver projects smoothly.

Hive Engineering uses ArchiCAD to create our models and document our work. We find that we can achieve extraordinary results and often surprise ourselves. We have tailored ArchiCAD to effectively deliver engineering projects, and are constantly upgrading and improving our processes.

Recently, Hive Engineering has been working using shared models accessed over the internet using ArchiCAD's Teamwork2 BIM Server technology. The model can be simulataneously built across disciplines and the project delivery is very rapid. Cross disciplinary project delivery in this way is a first in Australia, and appears to be the future of the design profession.

We are extremely competent at dealing with the technology side, and we have been regularly asked to speak at conferences and lecture at university.
