Our team is always ready to help you.
Helioz Technologies can help you to get a start to understand BIM. If you are at the very beginning with BIM, we can help you to create a BIM strategy. Are you already working with BIM, and need help to create 3D models with added metadata?
The recommended route to create a BIM strategy is first to collect and analyze company information. Helioz consultants will collaborate with you and create a report needed to create a BIM strategy.
The report is company specific and will contain classification data requirements for different markets. The level of complexity needed for BIM product data targeting different user groups. Most companies have already invested in 3D designs of their products. The Helioz approach of reworking and simplify existing CAD models to create new BIM models delivers the best value to our clients and avoid unnecessary investments in rebuilding what already exists.
A number of different BIM applications are used among architects and engineers. As a manufacturer, it’s important to know which file formats their customers are using. The most popular BIM applications are coming from Autodesk, Graphisoft, Nemetschek and Trimble. Beyond formats for the main BIM applications other commonly used formats are IFC, 3DS, DWG and WebGL.
The important file format IFC (Industry Foundation Classes) is not native to any BIM application but an open international standard for BIM data exchange between different software applications. All major software applications worldwide support the IFC standard.
A BIM model contains more information than only the geometry itself. Information about the asset, so-called metadata, belongs to the model as well. An added challenge to delivering BIM data worldwide is that fact that metadata requirements vary depending on the market/region where the product is used. Adding the correct metadata is part of the development process when digital assets are created.
In the new era of electronic commerce, products and services have to be classified as a common coding scheme to facilitate commerce between buyers and sellers. Several classification systems are used for BIM related assets and services. Depending on country different classification systems are used.
Commonly used classification systems include:
UNSPSC - The United Nations Standard Products and Services Code®, managed by GS1 US™ for the UN Development Programme (UNDP), is an open, global, multi-sector standard for efficient, accurate classification of products and services.
Uniclass - A unified classification system for all sectors of the UK construction industry.
NBS (National Building Specification) - Innovative specification and information solutions to construction industry professionals in the UK construction industry.
CSI - From the Construction Specifications Institute (CSI) has developed two different classification system. UniFormat and MasterFormat. The primary difference between UniFormat and MasterFormat lies in how each views construction information.
CSI MasterFormat - Information in MasterFormat is arranged by work results, defined in MasterFormat as “permanent or temporary aspects of construction projects achieved in the production stage or by subsequent alteration, maintenance, or demolition processes, through the application of a particular skill or trade to construction resources.“
CSI UniFormat - Identifies elements, each with one or more characteristic functions. For example, foundations provide the function to stabilize and support.
OmniClass - The OmniClass Construction Classification System is designed to provide a standardized basis for classifying information created and used by the North American architectural, engineering and construction (AEC) industry.
