What’s BIM

BIM Stands for Building Information Modeling. BIM is an integrated process for exploring a project’s key physical and functional characteristics digitally. BIM enables earlier decision-making, better documentation, and the evaluation of alternatives for sustainable design or improvements based on early stage analysis before construction begins. Models includes graphic, physical, commercial, environmental and operational data. BIM enables us to:

  • Visualize:

Visualize the construction site

  • Optimize:

Optimize the construction schedule

  • Reduce Risk:

Reduce project risk, request for information and on-site change orders

  • Clash Identification:

Leverage mechanical and electrical systems 'clash identification' in order to deliver more accurate shop and coordination drawings

  • Estimation:

Assess building components throughout the life-cycle of a structure from concept to occupancy, supporting design phases, construction cost, project management and facility management

  • Sustainable design:

More efficient buildings that people will love

Typical benefits of the BIM process include:

  • Early analysis of various design options to see the best value and maintaining the most sustainable solution
  • Cost effective designs produced using the latest modelling techniques and tools
  • Reduced risk, as the design solutions are actually virtual model, allowing all project team members to co-ordinate and arrive at the appropriate overall solution, which the client can actually see
  • Project delivery timeline is reduced as the models are used to review the most appropriate construction methods and logistics as well as looking at complex issues and clash detection avoidance
  • Constructional and operational safety risks are reduced by the use of the model to analyze the most suitable solution, including the ability to assess people movement and time taken to evacuate
  • Right first time approach is a reality with the modelling as co-ordination takes place at design, ensuring design is not modified at construction stage, with the consequential impact of time and money
  • Waste during the construction phase is reduced as the quantities can be more accurately taken direct from the model, and the programming capability allows for deliveries timed to minimize damage whilst stored on site
  • Lifecycle asset management with real data attached to the model. This includes the operation and maintenance activities required, parts and methods of shut down, disassembly and restart as required
  • Design data can be compared to operational data with subsequent corrections or improvements to keep the operational costs as low as possible


4D - 5D BIM Modeling

4D Modelling – Simulation Based Modelling

BIM Junction offers 4D BIM, also called Simulation Based Modeling where we integrate components of the 3D BIM with time and schedule related information. With these 4D BIM models, we enable our clients to demonstrate a graphically rich and animated representation of their planned construction sequence set against time.

5D Modelling

5D Modelling comprises the integration of design with estimation, scheduling and costing, along with generation of Bills of Quantities (BOQs), derivation of productivity rates and labour costs. The project’s cost data is accurately linked to each element resulting in a detailed cost schedule. BIM Integration

LOD - Level of Development/Detail

The Level of Development (LOD) is a reference that allows specialists in the AEC Industry to specify and articulate through a high level of clarity the content and reliability of Building Information Models (BIMs) at various stages in the design and construction process.
