BUILDING INFORMATION MODELS
Collaboration across disciplines and software
BIM stands for “Building Information Model.” But as BIM is also a working method and a way of managing the information in the construction process, the “M” could also stand for “modelling” or “managing”. There are many ways to work with BIM. Many different programs and tools make it possible to get more out of BIM, regardless of what part of a construction process you are involved in. What is important here is not the tools, but the content of the models. BIM Equity works to maintain focus on the content of BIM and the possibilities for sharing this between the different stakeholders involved in the construction project. The opportunity to use BIM to do good business demands that you utilise the information contained in the models.
There are many different BIM programs on the market. Almost all of them have a common characteristic: they can share models via a common file format called IFC. This open, international standard makes it possible to exchange the information in the models between consultants, contractors and developers.
IFC ensures that anyone can use the best tools and thus themselves choose how they wish to utilise the content of the models. BIM Equity sells a range of programs that support the IFC format and contain tools that make it easy to share one’s knowledge about a building with the project team and the developer. This knowledge thereby becomes central to the project work, and the more knowledge there is about the building, the better the building will be.
OpenBIM is an international standard for building design, construction and operation that is based on open standards and working methods. OpenBIM has been developed in a collaboration between the non-profit organisation Building SMART and leading software developers in the construction industry such as GRAHISOFT, SOLIBRI and Tekla. BuildingSMART certifies software programs that support IFC and OpenBIM, which ensures that the exchange of data between certified applications functions in the best possible way.
BIM as the focal point of the project
BIM Equity always works to share as much knowledge as possible between the stakeholders involved in the project. It’s about compiling project material and perhaps professional models in one model, which the project team and the developer review together. This type of model coordinates consultants’ projects, which can then be used as tender documentation or for calculating quantities, price (4D), time consumption (5D) and logistics.
With the right tools and server technology, the BIM project can be shared between the different parties, so everyone has the opportunity to make changes that will automatically be “accepted” by all of those involved in the construction project. BIM is an effective way to ensure a high level of quality and the right solutions, which ultimately create better architecture. In this way, the contractor always has an updated basis of calculation, while the drawing material becomes a dynamic data extraction from the model. This means you have the advantage of being able to share the BIM project between parties — also out at the construction site, where communication between workmen and the project consultants can take place with the 3D model as the central element. This model is updated and adjusted during the construction phase, so that when the building is completed, you have a precise model of the finished building. This “As Built” model can then be the basis for operation and maintenance.
If the construction process is streamlined according to this recipe, then all parties will have the opportunity to really profit from it. The building will have fewer errors, and can be built quicker at a lower price. – And the result will be closer to the developer’s wishes. This means that investment in the right working method pays off from the very first project.
At POLYFORM architects OpenBIM creates an environment where 2D drawings and 3D models will be part of the same workflow shared with engineers, contractors and owners. This creates transparency in the project, which leads to higher internal efficiency, better collaboration in the project team and less risk to the contractor.
