Building Information Modeling (BIM) in Indian Real Estate

Building Information Modeling (BIM)

 

Building Information Modeling or BIM is the creation of an electric model which in use for visualization, analysis and as-built products to achieve one or more specific objectives.

 

 

 

 

Uses of BIM (Building Information Modeling):

  1. Gather
  2. Generate
  3. Analyze
  4. Communicate
  5. Realize

 

I. Gather: BIM is used for gathering the information about the specific amount of an element or the determination of the current status of the element for managing the asset.

 

The sub-purpose of Gather includes:

  • Capture
  • Quantify
  • Monitor
  • Qualify

 

  • Capture: BIM is used for capturing the geometric and attribute data about a facility. The data is being captured by using a laser scanner or recorded manually by inputting model and serial numbers into a spreadsheet which shows the elements of a site which is prior to the development of a new facility or the existing facility which is prior to the renovations.
  • Quantify: It is used for the purpose of estimation and cost forecasting process as during the design phase, the quantities may be defined broadly and can be represented by a range and change in subject.
  • Monitor: BIM is used for monitoring the real-time performance data of a particular facility elements and activities.
  • Qualify: This is used for tracking the status of the facility element.

 

II. Generate: It is used for the creation or author information about the facility to various levels of development. In the design phase, the design team will be the primary generators of information and in the construction phase, the subcontractors will generate most of the information.

 

The sub-purpose of Generate includes:

  • Prescribe
  • Arrange
  • Size

 

  • Prescribe: This purpose of BIM is used as when a generator determines there need for a specific facility element.
  • Arrange: This is used for the determination of a location and placement of facility elements
  • Size: This is used for the determination of the magnitude and scale of the facility elements.

 

III. Analyze: Analysis is done for the determination of the variability of the elements for their facility.

 

The sub-purpose of Analyze includes:

  • Coordinate
  • Forecast
  • Validate

 

Coordinate: The coordinating purpose is used in BIM for analyzing and ensuring the relationship between the facility elements and the other elements which includes the coordinating design intent of various systems during design, coordinating fabrication and installation during construction or coordinating existing operations while renovations are underway.

Forecast: This purpose of BIM is used for the prediction of the future performance of the facility and facility elements.

 

The primary performance factors include:

  • Financial
  • Energy
  • Flow
  • Scenario
  • Temporal

 

  • Financial Forecasting: It includes the cost estimation for both of the first cost of construction and the life cycle cost of a facility.
  • Energy Forecasting: It predicts about the future energy consumption.
  • Flow Forecasting: It predicts on the performance related to air flow or the occupants.
  • Scenario Forecasting: It focuses on the emergencies facilities such as fire, flood, evacuation, and others.
  • Temporal Forecasting: It predicts on the time management which includes the building degradation and element replacement.

 

Validate: This include the checking information for the accuracy to ensure about its logical and reasonable

 

The primary areas of Validation are:

  • Prescription
  • Functionality
  • Compliance

 

  • Prescription Validation: The elements which are specified and programmed within the facility which includes the primary element of the facility such as spaces or rooms.
  • Functionality Validation: It gives the ensurity about the facility which is constructible, maintainable and usable.
  • Compliance Validation: It gives the confirmation of a facility’s compliance with the codes and the standards which includes building codes, ADA standards, sustainability standards and others.

 

IV. Communicate: This purpose of BIM is used for presenting the information related to a facility which can be shared or exchanged.

 

The sub-purpose of communicate are:

  • Visualize
  • Transform
  • Draw
  • Document

 

  • Visualize: This BIM is used for a purpose of implementation to form a representation of the facility or facility elements
  • Transform: The transformation of data is taken from one form to another so that it can be received and can be used for the current infrastructure.
  • Draw: This purpose of BIM is used for the symbolic representation of the facility or facility elements which includes all the detailing information regarding the elements
  • Document: It is used for creating a record of facility elements information which includes specifications, submittals, design schedule and other reporting of facility data.

 

V. Realize: The BIM data is used for controlling a physical element of the facility which leads to the improved productivity of both construction and operations of facilities.

 

The sub-purpose of Realize is:

  • Fabricate
  • Assemble
  • Control
  • Regulate

 

  • Fabricate: This includes the facility information which can be directly used for the manufacture elements of the facility.
  • Assemble: This is used for assembling all the information together which is available for the separate elements of a facility.
  • Control: This includes the facility information which is used for the physically manipulation of the operation of executing equipment.
  • Regulate: It is used for informing the operation of a facility element.

 

Characteristics of Building Information Modeling (BIM):

 

  • Facility element
  • Facility phase
  • Discipline
  • Level of development

 

  • Facility element: It is required for the determination of the elements on which the BIM uses will be executed which includes Substructure, Shell, Interiors, Services, Equipment and Furnishings, Special Construction and Demolition and Sitework.
  • Facility phase: The phase in which the planning team should determine that in which facility phase they will implement the BIM uses.
  • Discipline: The discipline corresponds with the various project roles which include planning, design, investigation, project management, construction, facility use, and support.
  • Level of Development: It is used for the identification in order to maximize the benefit from the BIM use which describes the level of detail or granularity to which a Model Element is developed.
