Record Modeling is the process used to depict an accurate representation of the physical conditions, environment, and assets of a facility. The record model should, at a minimum, contain information relating to the main architectural, structural, and MEP elements. It is the culmination of all the BIM Modeling throughout the project, including linking Operation, Maintenance, and Asset data to the As-Built model (created from the Design, Construction, 4D Coordination Models, and Subcontractor Fabrication Models) to deliver a record model to the owner or facility manager. Additional information including equipment and space planning systems may be necessary if the owner intends to utilize the information in the future.
- Aid in future modeling and 3D design coordination for renovation
- Improve documentation of environment for future uses, e.g., renovation or historical documentation
- Aid in the permitting process (e.g. continuous change vs. specified code.)
- Minimize facility turnover dispute (e.g. link to contract with historical data highlights expectations and comparisons drawn to final product.)
- Ability for embedding future data based upon renovation or equipment replacement
- Provide owner with accurate model of building, equipment, and spaces within a building to create possible synergies with other BIM Uses
- Minimize building turnover information and required storage space for this information
- Better accommodate owner's needs and wants to help foster a stronger relationship and promote repeat business
- Easily assess client requirement data such as room areas or environmental performance to as-designed, as-built or as-performing data.
- 3D Model Manipulation Tools
- Compliant Model Authoring Tools to Accommodate Required Deliverable
- Access to Essential Information in Electronic Format
- Database of Assets and Equipment with Metadata (Based upon Owner's Capabilities)
Team Competencies Required:
- Ability to manipulate, navigate, and review 3D model
- Ability to use BIM modeling application for building updates
- Ability to thoroughly understand facility operations processes to ensure correct input of information
- Ability to effectively communicate between the design, construction, and facilities management teams

In order to properly exhaust all opportunities for utilizing such a model, dialog must take place before the project begins. The critical factor to the success of creating a record model comes with properly documenting the owner's intended use of the information stored within the model. Once these uses are outlined, the necessary parties can produce the required information and embed the necessary infrastructure into the model to support this future information. Other resources such as a deliver/turnover strategy, comprehensive implementation plan and level of detail documents must also be established. Â Furthermore, with the continuous updating and improvement of the record model and the capability to store more information, the model serves as a living document that contains an accurate snapshot of the completed space. The model should contain necessary links to pertinent information such as serial codes, warranties, and operation and maintenance history of all the components within the building. Subsequently, this model could be used to monitor the efficiency of the building from an operating standpoint. The record model also contains information linking pre-build specifications to as-built conditions as well as post-construction/operations/renovations. This allows the owner to monitor the project relative to the specifications provided. Additionally, if the model contains the systems described herein, the owner could potentially use the model to aid in future projects and can effectively serve as an existing conditions model for any subsequent projects. This process should repeat with every modification to the building in order to maintain an accurate depiction of the space and equipment within. Finally, it is important that the owner views the facilities maintenance as beyond just a “glorified janitor” while the A/E and CM/GC’s consider post-construction design issues just as much as early design phases and pre-construction activities.
