FAQ

BIM, or Building Information Modelling, is an integrated process that relies on coordinated and reliable information. It goes beyond just 3D CAD or a new technology application; it's about creating coordinated digital design information and documentation. With BIM, you can predict performance, appearance, and cost, ultimately delivering projects faster, more economically, and with reduced environmental impact. At its core, BIM ensures that there's always a single source of truth throughout the project lifecycle. It fosters value-creating collaboration by utilizing shared 3D models and intelligent, structured data. In essence, BIM is not a future concept—it's here and now, revolutionizing how we approach construction projects.

There is a misconception within the industry that the building information model is a single 3D file, filled with information. In fact, BIM encompasses a variety of files and components. It includes graphical models that evolve from conceptual shapes into detailed 3D models with linked 2D elements. Additionally, BIM incorporates non-graphical data like properties, specifications, and cost information, often managed in databases. Documentation, such as floor plans and schedules, is also part of the BIM. Together, these elements form the comprehensive Building Information Model, essential for both project development and ongoing asset management.

In BIM, we deal with multiple dimensions. incorporating aspects such as 2D, 3D, 4D, and 5D. Each dimension adds unique aspects to project management and planning in the construction industry. These dimensions work together to enhance project planning and management, enabling stakeholders to visualize, schedule, and estimate costs effectively.

In BIM, "2D" refers to the basic line work similar to traditional drafting. It involves creating geometric representations without depth, commonly used for floor plans, elevations, and sections.

"3D" in BIM represents objects with depth and attached data, allowing for detailed specifications. It enables the creation of comprehensive 3D models, facilitating visualization and coordination among project stakeholders.

"4D" in BIM integrates time into the project by linking project schedules with the 3D model. This dimension enables stakeholders to visualize the construction sequence and plan project phases more effectively.

In BIM, "5D" incorporates cost estimation into the digital model, utilizing additional software for accurate expense assessments. This dimension enhances project planning and management by integrating cost considerations with the 3D model and schedule.

UK BIM Level 2 involves a structured approach to BIM implementation, supported by a series of documents and standards. It includes managed CAD in a 3D environment, with federated models and data attachment, incorporating aspects like 4D and 5D elements. Key documents include PAS1192-2 for information management during the capital phase, PAS1192-3 for information management during the operational phase, and other supporting standards like BS1192 and BS8541 series. These standards aim to remove adoption barriers and ensure consistency and efficiency in BIM implementation across the UK construction industry.

OpenBIM facilitates collaborative design through open standards, enabling seamless information exchange among various software tools. It promotes data sharing and interoperability, fostering innovation in the construction industry. Industry Foundation Classes (IFC) serve as an open data format, ensuring comprehensive data exchanges without loss of information, thus enhancing interoperability among different software tools.

Employer's Information Requirements (EIR) outline the specific information that the client or employer needs from a construction project. These requirements include details on project objectives, deliverables, standards, and desired outcomes regarding information management and exchange throughout the project lifecycle. Essentially, EIR serves as a roadmap for how information will be managed, structured, and delivered to meet the client's needs and expectations.

BIM Execution Plans (BEPs) are crucial documents drafted at the initiation of a project, detailing the management and exchange of project information throughout its lifecycle. Divided into pre-contract and post-contract phases, BEPs outline project objectives, milestones, strategies for information delivery, and responsibilities within the supply chain. They ensure alignment with Employer's Information Requirements (EIR) and facilitate seamless collaboration among project stakeholders.

Failing to utilize a BIM execution plan means businesses and project teams will continue creating local, non-reusable, and non-interoperable solutions repeatedly. This results in prolonged time-to-market for new products and services due to inefficient sharing of ideas and results among collaborating parties.

Moreover, designs may contain more errors and omissions than necessary, leading to costly corrections during construction. Redundant data entry becomes prevalent, requiring information to be inputted multiple times instead of being utilized efficiently.

Additionally, the absence of comprehensive performance insights during the design phase may result in increased resource consumption throughout the facility's lifecycle. This could lead to decreased efficiency due to overlooked functional and environmental constraints that could have been addressed during pre-construction testing.

LOD, or Level of Development, refers to the degree of detail and accuracy of a BIM model at different stages of a project. In the UK, LOD levels are commonly categorized as LOD 100, 200, 300, 400, and 500. Each level represents increasing detail, from conceptual to highly detailed models suitable for fabrication and construction.

LOD 100 represents the conceptual design stage in BIM. It involves basic geometric representations, indicating the general shape, size, and orientation of elements within the model.

LOD 200 corresponds to the schematic design phase in BIM. It entails more detailed geometry with approximate quantities, sizes, shapes, and locations of elements within the model.

LOD 300 denotes the design development stage in BIM. It involves accurate geometry with specific quantities, sizes, shapes, and locations of elements within the model, suitable for coordination.

LOD 400 refers to the construction documentation phase in BIM. It includes accurate geometry with detailed information necessary for fabrication and construction purposes.

LOD 500 signifies the as-built phase in BIM. It represents the real-world physical characteristics and arrangement of elements within the model, furnishing accurate geometry and comprehensive information post-construction.

A Common Data Environment (CDE) is a centralized digital platform where project teams collaborate and manage project information throughout the construction lifecycle. It includes areas for work in progress, shared data, and archived records, with defined gateways between them. Utilizing standardized naming and revision conventions, the CDE ensures efficient information exchange and version control among stakeholders. For example, a CDE could consist of folders on an extranet or a cloud-based platform like BIM 360 where approved files are stored and accessed by authorized team members.

COBie, short for Construction Operation Building information exchange, is a structured method for capturing non-graphical data from the information model. It enables the exchange of information between various phases of the construction lifecycle, including design, construction, and maintenance. COBie facilitates standardized data sharing among different software tools and supports efficient communication and collaboration throughout the project.
