BIM and its benefits to the construction industry

In present time, BIM services are considered as leading services within the construction sector. Within paste few years the services have also managed to gain a lot of exposure and popularity.

BIM in itself is a process that proves helpful in management of functional and physical information related to the project. The output of the service is termed as BIM (Building Information Models) and is available in the form of files in the digital format. It proves helpful in supportive decision taking and project description.

About BIM

So in simple language, BIM is a type of representation in the digital format for functional and physical characteristics for any project or facility. It is also described as a knowledge resource that is shared amongst clients and service providers alike during the project cycle. It proves helpful in covering various aspects of a project cycle including – building components properties, material quantities, information of geographic, light analysis and spatial relationships.

BIM tools and Objects

BIM makes use of various object combinations – generic, void space, solid shapes, product specific, undefined and vague. Using the BIM design tools, designers are able to extract all set of information for producing a drawing from the model. The tools also integrate different views of the object and define the parameters, such that a small change in one will automatically change all other adjusts.

These changes can be used by clients or firms to work out various other elements including material to be used, cost and material tracking.

Various Dimensions under BIM models

Dimensions are used ot describe each element under the BIM –

  • 3 D for Object Model.
  • 4D for Time estimation.
  • 5D for Cost estimation.
  • 6 D for Operational.
  • 7D for studying sustainability factor.

Integration of various BIM Dimensions (5Ds) in a 3D output

BIM – Functional characteristics and Physical characteristics Digital format representation. It is helpful in forming accurate basis for making important decisions during the ongoing project cycle. The working of all dimensions can be explained as below:-

  • Each of the element (3D) model are linked together during execution phase or schedule.
  • Elements are also made use of for developing over head cost, and set fixed budget for project completion.
  • Information is embedded within the model – Geometry, Geographical information, exact specs, thermal properties, Aesthetics and Acoustic properties.

Benefits of BIM models

Facility management can be enabled using the 6D models in BIM. It is helpful in adding features that are rich for describing the building (engineering services and elements) along with other elaborative factors (Geometry, property and relationships) to prepare an accurate management database.

Sustainability component is added to the above mentioned components in the 7D model. This set of information proves helpful for designers when preparing project for comparison and test decisions.

Within 8D models you can embed the safety aspects in the project management. This process helps in automating the project cycle. This also helps in improving the construction for overcoming the qualification stage.
