Introduction
In recent years, Building Information Modeling (BIM) has become a pivotal component in the design and construction processes, helping architects, engineers, and contractors streamline their projects. However, building owners are now realizing the next phase of BIM's potential—extending its application throughout the entire lifetime of a building. This involves creating a Lifetime BIM plan that allows the integration of BIM data into facility management (FM) processes, ultimately improving the operational efficiency of the building over time.
Facility managers, with the help of BIM for Facility Management (BIM FM), are now able to streamline building operations, improve maintenance workflows, and manage energy consumption, among other crucial responsibilities. Effective implementation of Lifetime BIM involves careful planning and coordination to ensure all relevant data is collected, maintained, and accessible throughout the building's operational life.
A comprehensive BIM FM plan should cover several key points:
- Information Requirements: What data should be included in the BIM model to support ongoing operations and lifetime planning? This includes asset management details, maintenance schedules, and product specifications.
- Process and Responsibilities: Who is responsible for creating and maintaining this data throughout the lifetime of the building? This includes ensuring that privacy policies are adhered to and that sensitive data is protected.
- Data Collection: At what stages should the data be gathered, and which methods should be used to populate the model? This will ensure that facilities are properly managed and optimized for efficiency throughout their lifetime.
- Model Detail Level: What level of information, including both graphical and data elements, needs to be incorporated into the BIM model? A comprehensive model ensures that all assets and products within the facility are easily trackable and manageable.
This guide aims to explain the principles and practices for applying BIM in facility management, focusing on how it can be used to manage building operations effectively over the course of the building's lifetime. With BIM, facility managers are empowered to handle everything from asset management to long-term maintenance and upgrades, ensuring the smooth and efficient operation of their facilities.

BIM Uses for Facility Management
Lifetime BIM refers to the practice of utilizing a digital model of a facility throughout its entire lifetime, from construction to demolition. BIM FM involves leveraging this data to enhance facility management and ensure efficient facility operations. Below are several key areas where BIM is proving to be valuable for facility managers:
Improved Space Management
BIM plays a crucial role in space management by providing accurate, real-time data about how space is being used. With detailed room and area information available within BIM models, facility managers can optimize space utilization, reduce vacancy rates, and make more informed decisions on space allocation. This can lead to substantial savings in real estate expenses and the ability to make the most out of available space. By using BIM as part of their facility management software, facility managers can ensure that space is allocated efficiently, meeting both the current and future needs of the building.
Streamlined Maintenance
One of the key challenges in facility management is creating a maintenance program that can effectively address the upkeep of all building systems and equipment. BIM models house essential data regarding building equipment, systems, and assets, which can significantly reduce the time and effort required to populate maintenance management software. Information like manufacturer specifications, service histories, and maintenance schedules are readily available, allowing for more efficient and proactive maintenance planning. With BIM, facility managers can stay ahead of maintenance needs, minimizing downtime and extending the lifespan of equipment and systems.
Energy Efficiency Optimization
BIM is an invaluable tool for improving energy efficiency and reducing operating costs. Facility managers can use BIM data to conduct energy audits, compare different energy-saving solutions, and assess the potential benefits of upgrades or retrofits. The ability to simulate building performance and identify energy inefficiencies helps managers optimize building systems, reduce environmental impact, and lower long-term energy costs.
Economical Retrofitting and Renovation
BIM also provides a more effective approach to managing building renovations or retrofits. With a living BIM model of the building, facility managers have access to up-to-date, accurate data about the building's existing conditions, which makes the renovation process smoother and more cost-effective. By reducing surprises during construction, BIM enables contractors to plan more effectively and mitigate risks associated with change orders or unexpected complications.
Enhanced Lifecycle Management
A BIM model with lifecycle data embedded in it provides insight into the long-term performance of building materials and systems. For example, BIM can include data on the life expectancy and replacement costs of materials, helping facility managers make better decisions about investments in building systems. Using this information, owners can choose materials or systems that may have higher initial costs but offer better long-term payback, reducing overall lifecycle expenses.

FM Data Requirements for As-Built BIM Models
Purposes of the As-Built BIM Model
Source for BIM FM Model Development
The As-Built BIM model serves as the foundational data source for developing the Facility Management (FM) BIM model. The FM model is a streamlined version of the As-Built model, where only the essential operational data relevant to facility management is retained. This enables facility managers to effectively manage building operations while maintaining a connection to the original design and construction details. The benefits of BIM in this context are clear, providing facility managers with a reliable, data-driven approach to managing a building’s operations and lifecycle.
Source of Record
The As-Built BIM model is the official reference for the building’s construction state. It contains accurate representations of the building’s physical components, including structural, architectural, and systems information. Facility managers use it as the primary source for decision-making and operations, from maintenance to asset replacement. This model ensures that all operations are grounded in the actual built environment, improving the efficiency and accuracy of facility management processes.
Reference for Future Renovations and Expansions
As-Built models are also used for future renovations, retrofitting, and expansion projects. The accurate data provided by the As-Built model ensures that any changes to the building are carried out with a clear understanding of the existing conditions, reducing the risk of costly errors and delays. In the construction industry, this level of precision is invaluable, particularly when planning for building upgrades or addressing unforeseen issues during renovations. The As-Built model serves as a critical reference point to avoid conflicts and ensure that projects proceed smoothly.
BIM As-Built Model Requirements
For the As-Built BIM model to be effective for facility management purposes, it must meet certain data requirements. These requirements ensure that the model is comprehensive, accurate, and capable of supporting facility management systems.
The following types of models should be delivered as part of the As-Built BIM package:
- Architectural Models: This includes all floor plans, elevations, sections, and details, reflecting the exact dimensions, materials, and finishes of walls, floors, roofs, and openings in the building.
- Structural Models: Detailed structural models that include columns, beams, load-bearing walls, foundations, and other structural elements. These models provide insights into the load-bearing capacity, material specifications, and structural integrity of the building.
