BIM objectives

BIM objectives (BIM goals) are the ways in which the BIM model is used – specific project goals to be achieved using BIM tools at different stages of the lifecycle of the facility.

For example, whether the model will be used in construction logistics, because it will also need to be populated with at least 4D BIM (time) information. Or whether the client’s parent company requires a precise, weekly cost breakdown of the project, or at some point a hyper-realistic virtual tour for board members, showing multiple scenarios. Should we take into account the parameters of a particular building management software used within a group of companies when feeding the model with information?

What are the BIM objectives?

The uses of BIM by purpose, in broad terms, with a few examples:

Collect and organize facility information

• scanning existing buildings
• automatic quantification of building materials from a model
• request energy data
• classification of building elements

Generate information about the facility

• details and information content of facility elements,
• location and placement
• magnitude and scale

Analyze and examine for better understanding

• coordination (including e.g. clash detection)
• simulations and analyses for predicts
• checkings and validations

Exchange and share information (communicate)

• visualization (e.g. 3D building tours)
• convert data to other formats
• graphic representation (e.g. symbols)
• documentation (e.g. PPM documentation)

Physical realization of information

• CAD/CAM-based fabrication
• prefabrication and assembly
• model-based construction support
• model-based facility management

The definition of BIM objectives is a basic requirement for projects. Taking these into account, the designer office quotes a price and coordinates the engineering hours.

Unfortunately, due to its complexity, infinite possibilities, relative novelty (in our country), and misunderstanding, BIM is often only partially or superficially defined. Another problem is the “under-application” of the BIM methodology, the resulting problematic projects, and the short-term interests (let’s be cheap) in the widespread application of BIM goals.

The BIM objectives are defined by the client in the EIR (Exchange Information Requirements) document, to which the supplier side responds with the BEP (BIM Execution Plan). Both require an experienced BIM manager.
