What is 5D BIM? Comprehensive Guide 2024

Traditionally, the objective during pre-construction and early design conceptualization has been to establish an unalterable design. Rather than allowing the design to evolve, the aim is to produce architectural drawings that remain unchanging and serve as the basis for construction. However, due to the inherent imprecision of early-stage drawings, achieving an accurate “frozen design” stage and fully understanding all aspects of design intent—such as how facilities will function, how they will be constructed, and their associated costs—has proven challenging. Consequently, this process often leads to unforeseen, costly, and time-consuming design changes during the construction phase of many projects.

The pre-construction and early-stage design phase is a critical period that necessitates consensus regarding the scope of work, which should be based on the owner’s requirements and expectations, as well as precise cost estimates for project deliverables. In today’s context, 5D BIM enables owners, architects, builders, and engineers to collaborate from the very beginning of the design process, allowing them to not only evaluate the current design but also assess how design revisions or alternatives will impact the project from its initial stages through to completion. All aspects, including appearance, cost, schedule, and constructability, can be visualized and evaluated.

What is 5D BIM? Understanding BIM Basics

Building Information Modeling (BIM) has rapidly gained worldwide popularity. It represents a time and cost-effective approach that has become the norm for many projects, facilitating highly efficient and collaborative planning, design, and construction processes.

In the United States, nearly half (49%) of construction firms employ BIM for visualization purposes, reflecting the industry’s substantial growth. Projections indicate a robust compound annual growth rate (CAGR) of 14.3% through 2027, with experts foreseeing revenue reaching $15.06 billion.

An increasing number of projects mandate BIM, often as a requirement for government initiatives. For instance, the UK adopted BIM mandates following an analysis revealing potential savings of up to 20% in construction costs. In practical terms, utilizing BIM at LOD (Level of Development) 300-400 resulted in savings of approximately £900 million (equivalent to roughly $1 billion USD) over a six-year study period.

Building Information Modeling (BIM) constitutes a collaborative process that facilitates the joint efforts of multiple stakeholders and architecture, engineering, and construction (AEC) professionals during project planning, design, and construction via a 3-D model. It offers real-time updates at each project stage.

Leveraging advanced building and design solutions, BIM generates virtual representations that proactively identify clashes, reducing risks and surprises during construction while potentially lowering overall project expenses.

A synchronized database empowers owners, project managers, estimators, and other stakeholders to make data-driven decisions both before and after project completion. BIM’s utility extends to estimating, budgeting, and long-term building operations and management throughout the building’s lifecycle.

What do BIM Dimensions Mean?

BIM dimensions emerged to distinguish between modeling in two or three dimensions, reflecting the evolution from manual drawing boards to early 2D CAD systems and subsequently 3D modeling tools.

In this context, 4D BIM represents the incorporation of scheduling information to depict construction sequences, while 5D BIM involves the inclusion of financial cost data. It’s worth noting that there’s limited international consensus regarding these “dimensions,” and cost may not truly constitute a dimension but rather additional information.

At NBS and within international standards, these dimensions aren’t typically referenced. Instead, the focus is on clearly identifying the specific information that needs to be modeled, such as health and safety, fire safety, inclusive design, or sustainability. Project requirements should specify the necessary information fields and formats, like embodied carbon measurements or cost in pounds sterling and months.

Nevertheless, the more commonly used “dimensions of BIM” are explored below to facilitate discussions with clients, showcase various BIM applications, and refine precise project requirements.

2D BIM encompasses a digital geometric model with X and Y axes, with associated information. Early CAD systems were essentially 2D models, enabling quicker and more accurate generation of plans and sections compared to manual drawing boards.

3D BIM involves a digital geometric model incorporating X, Y, and Z axes, along with additional information. These 3D modeling tools offer advantages such as generating 2D views, creating schedules, and identifying geometric clashes, thereby enhancing accuracy, efficiency, and error reduction.

4D BIM integrates scheduling information to depict construction sequences, aiding visualization of construction progression over time. This is particularly valuable from a contractor’s perspective, showcasing collaboration between design and construction teams through 3D model coordination.

5D BIM typically includes cost information in the model. When discussing 5D BIM, it’s essential to specify requirements regarding capital or operational costs, pre-tender estimates, responsibility for adding this data, and measurement methods.

6D BIM involves facility management information for some, but industry consensus is lacking. Precise definitions of required information are crucial to ensure clarity.

7D BIM may involve sustainability data, demanding specific details regarding data types, scope, units, rules of measurement, and so on.

8D BIM, for certain stakeholders, pertains to health and safety information. As with 6D and 7D BIM, explicit definitions of required data are vital for clear understanding among all parties involved.
