Build with BIM (Building Information Modeling)

The residential design and construction industry faces challenges ranging from project delays, cost overruns, design errors, and inefficient communication across the project team and with consumers and other stakeholders.

These inefficiencies lead to increased expenses and lower quality projects. But those working to stay ahead in the housing industry and maintain an edge in production, budget adherence, quality, and profitability have embraced Building Information Model (BIM).

With today’s technological advancements, utilizing BIM can revolutionize how you plan, design, construct, and manage your projects. In this article, we'll explore the key benefits of BIM and how you can leverage this technology to build smarter and more efficiently.

What is BIM (Building Information Modeling)?

Building Information Modeling (BIM) encompasses both Building Information Modeling and Building Information Management, offering a collaborative approach for various construction professionals to plan, design, and construct homes of all types—from single-family detached to low-rise multifamily—within a unified 3D model.

BIM revolutionizes building design by providing an intelligent 3D model supplemented with comprehensive data, including construction sequencing, cost, and lifecycle management information. By centralizing all relevant information in a single database, BIM facilitates design exploration, visualization, documentation, and lifecycle management to streamline project workflows and enable smoother collaboration among teams.

BIM in Residential Design and Construction

For home builders that have integrated BIM, the technology has profoundly transformed the way they do business by digitizing and centralizing project information throughout the building lifecycle. Architects, engineers, contractors, trade partners, and other stakeholders can use BIM to develop and share comprehensive digital representations that encompass not only the physical attributes but also the functional and operational aspects of the project.

Overall, BIM has become an indispensable tool for driving innovation, improving project outcomes, and shaping the future of the housing industry.

Key Components of BIM

BIM relies on several core concepts and components, including:

Objects and Elements: All elements, such as doors, windows, walls, and structural parts, are represented in BIM as objects. These objects possess both data properties and geometric shapes.
3D Modeling: BIM projects use a three-dimensional approach to provide a complete view of the building design. Such models help detect potential construction clashes and analyze spatial aspects effectively for the project team, homebuyers, neighborhood groups, and governing municipalities to gain faster approvals.
Data Integration: BIM integrates different data types, such as geometric data, attributes, time schedules, and cost estimates. Multiple stakeholders involved in a project can access and modify this data.

What are the BIM Levels?

BIM is classified into different levels based on the level of detail (LOD) and collaboration. The LOD determines how detailed and accurate the BIM model is at various project stages. The main levels of BIM typically referenced are:

BIM Level 0: This level does not involve collaboration or information integration among project stakeholders. Each stakeholder works with their own 2D drawings and shares minimal digital information. This level uses traditional CAD drafting methods and lacks the collaboration and interoperability features of higher BIM levels.
BIM Level 1: This level involves using 3D modeling for architecture, engineering, and construction separately. Each discipline creates its own 3D models with little collaboration.
BIM Level 2: This level is a big step up in collaboration and integration from previous levels. It includes creating individual 3D models for each discipline, which are then shared and coordinated in a common data environment (CDE). Modeling enables improved coordination and collaboration among stakeholders, with the capability to exchange information in a standard format like Industry Foundation Classes (IFC).
BIM Level 3: Also referred to as "Fully Collaborative BIM," this level enhances integration and collaboration. It focuses on creating a centralized project model that can be accessed by all stakeholders in real-time. This shared model allows for smooth collaboration and coordination between different disciplines, from design to maintenance.
BIM Level 4: This level introduces a new aspect to the information model: time. This data includes scheduling information that outlines the timeframe for each phase of the project or the order in which different components will be implemented.
BIM Level 5: This level includes cost estimations, budget analysis, and budget tracking in the information model. This level allows project owners to monitor and predict project costs.
BIM Level 6: This level provides information that helps calculate a building's energy consumption before construction, helping designers consider more than just initial costs, enabling accurate predictions of energy needs, and allowing stakeholders to construct energy-efficient and sustainable buildings.
BIM Level 7: This level helps efficiently manage and maintain facilities, including tracking assets and scheduling maintenance.

The benefit of BIM leveling is not only the functional upgrades at each stage, but also that builders and members of the project team can start at an early stage to get familiar and proficient before moving up at a comfortable and unified pace. In fact, starting at a later stage without any BIM experience would likely end in frustration and failure.

How Does BIM Work?

A building information model can be used throughout a project lifecycle to bring clarity and efficiency into a building's construction. Here’s how BIM works:

Planning: BIM software helps with project planning by using reality capture and real-world data to show how a building will look in its actual environment. This process can inform and guide users, making the process easier and more accurate.
Design: The design phase of a construction process is complex, involving conceptual design, analysis, and detailed documentation. BIM data offers detailed modeling that can help with construction organization and provide important information about design performance. It can also assist with logistics, streamline scheduling, and ensure all necessary personnel have the right information.
Construction: BIM project specifications and shared documents help to guide and optimize production.
