Egis now have some experience and practice in BIM processes for infrastructure projects especially in facilities constructed on the ground or under the ground for human activities development inside the territories1<\/sup><\/h2>\n

Compared to the buildings, the scope is larger, in terms of scales to be covered, systems to be developed and type of works to be constructed.<\/p>\n

If the development of the BIM for Infrastructure must avoid \u00a0\u201cre-inventing the wheel\u201d, the items of interoperability of data, tools and processes need to be re-visited in order to stay relevant and to provide some real added value.<\/p>\n

Level of BIM maturity In Infrastructure<\/h3>\n

The Building Information Modelling European Task Group, is agreed \u00a0that the average level of maturity possible is Level 2 with the objectives to deliver \u00a0for the year 2016. To simplify the concept, the BIM maturity Level 2 means: \u201cObjects and models in 3 dimensions delivered in using the available standards and collaborative processes (for instance, Workflow, libraries\u2026)<\/p>\n

Two schemas compare how Egis evaluates the Level 2 maturity for a construction to be considered in a building, like a metro station, and for a construction like a motorway, based on the experience of delivered projects in France or in Middle East.<\/p>\n

The processes for building are very much oriented by the 3D objects, natively managed by the authoring tools, using IFC<\/a> standard, but losing maturity with the collaborative processes due to the usual collaborative tools: they are mainly dedicated for files management.<\/p>\n

The infrastructure processes are more oriented models than objects which are not natively managed by the authoring tools. Nevertheless, because the collaborative tools are oriented files management, they appear relevant to manage the models files (workflow, versioning, etc.). It has to be mentioned, that the level of maturity cannot be homogenized for all of the works included in the infrastructure project and the extension of the standards are in progress with BSI and OGC.<\/p>\n

Data Drop or Concurrent Engineering (C.E.)<\/h3>\n

Two approaches are possible for the BIM management:<\/p>\n
