What you should know about bim architectural services

BIM-Building Information Modeling is a digital representation of the physical and functional characteristics of an object that creates a shared information resource for this object and forms a reliable basis for decision-making throughout its life cycle: from early concepts to disposal.

BIM is one of the most promising approaches that allows the development of one or more accurate virtual, digitally constructed building models to support the design, construction, production, and procurement activities through which a building is constructed.

3D format - allows you to visually demonstrate the object to the customer, find and correct collisions between engineering networks, and much more.

4D-time;

5D-cost;

6D-Sustainability: Energy analysis, stable element tracking;

7D-Object management programs

This model describes maturity levels in relation to the ability of organizations in the architecture and construction industry to produce, store, and share information.

​Modeling levels​

LEVEL 0 ​ Users apply traditional CAD in 2D format. In the drawings, building elements are represented by lines or arcs that define the geometry of the structure. Data exchange between project participants takes place on paper or electronic media.

LEVEL 1

Users apply CAD in 2D or 3D format. First-level models contain mostly basic information. Electronic files are used for information exchange. At this level, interaction between participants is organized through the Common Data Environment. However, there is no full-fledged interaction between participants belonging to different disciplines.

LEVEL 2 ​ A BIM project of this level is a complex model that specialists of various specialties are working on in parallel in various programs. Assembly of the general model, analysis and detection of collisions are carried out in special "assembly" software applications.

This level involves adding the following dimensions: 4D (time) and 5D (cost). For this level, data about the object is supposed to be generated in the format.

LEVEL 3

​The construction project is based on a single integrated model that is created and used by all participants in the process – the project customer, architect, designer, engineering services, contractors and subcontractors, and building owners. This is a fully integrated data bim architectural services and integrated process that uses web services and is compatible with the new Industry Foundation Classes standards.

Today, companies in the architecture and construction industry are at different levels of maturity and usually use BIM to solve narrow-profile problems. It will take time for the industry to accumulate enough knowledge and experience to gradually move from the first and second levels of maturity, where most of them are currently, to the third level-fully integrated BIM.
