A Product Model Server capable of storing all data for complex systems, including native support for any standard data model, like IFC, STEP, PLM/PLCS or Reference Data Libraries.


Jotne EPM Technolgy offers EDMmodelServer˙ to host a Building Information Model, BIM. Either you need to archive as-built models, exchange interoperable information between trades when designing or checking BIM according to rules given by physical laws, building authorities or company-specific knowledge databases or procedures.

The EDMmodelServer˙ is where data is stored in the open buildingSMART standards. The company's solutions provide efficiency to a project or process. Based on Express and ifc, rules, queries and mappings can create validations and checks. It can be extracted and merged with partial models to find the data needed for decision-making.

If a softwareprovider to the building and construction industy, make sure software seamlessly exchanges the information the client needs to provide to the building project or maintaining process.
