What is BIM?

BIM stands for Building Information Modelling, and is the process of designing a building collaboratively using a system of computer models, rather than separate sets of drawings. By generating and managing digital representations of the physical and functional characteristics of a facility, it helps you plan, design, construct, and manage buildings and infrastructure.

Many people think that BIM means 3D design, but it’s much more than that. It involves not just graphics, but information; information that allows the automatic generation of drawings and reports, design analysis, schedule simulation, facilities management, and more. The output of the process is the Building Information Model - the digital file which describes every aspect of the built asset and can be exchanged or networked to support decision-making.

Objects in the model are linked to related information including manuals, specifications, commissioning data, photos, and warranty details. This allows the owner or facility manager to efficiently and accurately manage the asset.

BIM data can be used throughout the entire building lifecycle, from inception and design to demolition and materials reuse. Spaces, systems, products and sequences can be shown in relative scale to each other and, in turn, relative to the entire project. This eliminates data redundancy, data re-entry, data loss, miscommunication, and translation errors.

BIM software is used by individuals, businesses and government agencies who plan, design, construct, operate and maintain diverse physical infrastructures.

What are the benefits of using BIM?

  • enables the building team to make better-informed decisions
  • allows better design coordination and improved constructability
  • brings together all of the information about every component of a building in one place
  • allows accessibility to this information
  • prevents errors creeping in at the various stages of development/construction by signalling conflict detection
  • creates enormous savings in cost and time
  • provides much greater accuracy in estimation
  • facilitates the avoidance of error, alterations and rework due to information loss.

Prefabrication and BIM

BIM has many benefits for the prefabrication and modular construction industries, too. While these industries have been around for decades, the power of computer programming has brought with it marked increases in efficiencies.

BIM allows you to model spaces and construction drawings not just in 3D but so that the
model knows exactly what material it is working with, what the tolerances are, and can then move
into a manufacturing process in which computers can accurately cut, like in the motor vehicle
world, and robots ultimately complete the assembly.

BIM facilitates design being more fully resolved and provides confidence that the on-site works and prefabrication elements will tie in as intended. This is crucial to the successful incorporation of prefabrication.

Using BIM and lean manufacturing technology, Interpod Offsite works with customers from design through installation to produce custom, ready-to-install bathroom pods for hotels, hospitals, universities, and multi-unit residential projects.

Design for Manufacture and Assembly (DfMA) and BIM go hand-in-hand for efficient modern construction projects. BIM is a vital part of realising the potential of DfMA, both as a component-driven tool for optimising the modularisation and standardisation that characterise DfMA, and as a way of delivering specifications for prototyping and manufacture.

One of the biggest advantages of BIM’s involvement in DfMA is this reassurance of having tested everything prior to construction, and the resulting reduction of risk that building a reliable product brings.

Using DfMA processes and guidelines driven by modularisation and standardisation, manufacturers gain the leverage they need to introduce lean manufacturing principles. DfMA is naturally suited to building types with inherent repetition such as student accommodation and hotels, as well as sensitive locations such as hospitals where it is essential to limit the amount of build time on site.

DfMA has an increasing commercial appeal for clients wanting to build quicker and more efficiently, thanks largely to the added capabilities that BIM brings. 3D modelling allows for the forward planning of the logistics of moving pods around a building and making sure they integrate with the rest of the building.

Software, tools and resources for BIM

When it comes to software for architecture and design, there are a multitude of different Building Information Modelling (BIM) options available to you. Finding the best package will depend on your specific needs, the types of features you require, the cost and the operating system that you use.

Ensuring you are using the right tools is the first step in operating efficiently and effectively. With so many available options across the entire project lifecycle, the main things to consider are the environment the software will be running in, the extent of collaboration and the requirement for interoperability. These sophisticated systems are powerful enough to handle your BIM needs.
