About this file
This document outlines the Building Information Modeling (BIM) requirements for a federal contract opportunity. The key details are:
The document defines the BIM submittal format, content, and quality control requirements for the project. It specifies the use of Autodesk Revit, IFC interoperability, and minimum modeling requirements for architectural, structural, and building systems elements. The model and associated facility/site data must be submitted at various design stages, including an initial design submittal, interim design submittals, final design submission, and a final as-built submittal. The government will review and accept the BIM submittals. Ownership and rights to the CAD files, BIM model, and facility/site data reside with the government. The document also provides detailed definitions of BIM terminology used throughout.
The related federal contract opportunity is for the General Services Administration (GSA) to lease office space in Imperial, CA. The solicitation package contains the Request for Lease Proposal (RLP) documents, but no other details about the requirements or procurement timeline are provided in this excerpt.

4.0 Section 4 – Minimum Modeling and Data Requirements
4.1 Minimum Modeling Matrix (M3)
4.1.1 Develop an M3 documenting elements included in the facility and site. The M3 describes the minimum modeling and data requirements by defining the Level of Development (“LOD”) and Element Grade. LOD will be determined during the Design Intent Document Phase.
4.1.2 Lessors shall use Attachment H: USCIS Minimum Modeling Matrix (M3).
4.2 Additional Requirements.
4.2.1 Classification. All modeled elements shall include Facility/Site Data referencing one or more classification system(s).
4.2.2 Spatial Data. The Model shall include spatial data defining actual net square footage and net volume, and holding data to develop the room finish schedule including room names and numbers. Include program information to verify design space against programmed space, using this information to validate area quantities.
4.2.3 Schedules. Schedules shall be produced from the Facility/Site Data within the Model. Any exceptions should be submitted to the USCIS for review.
4.2.4 Details and Enlarged Sections. All details and enlarged sections necessary for construction shall be derived from the Model when possible. For those details and enlarged sections not derived directly from the Model, Lessor must verify that geometry and data depicting the details and enlarged sections are consistent with Model elements. Details with significant drafted content such as 'standard' and 'typical' details shall not contradict the model and shall utilize the model as an underlay when possible for the purposes of verification and coordination. Three dimensional, isometric, and section isometric details derived from the model are preferred.
4.2.5 Legends. Model Elements shall be used to produce representations shown in the legends and shall match graphical representations shown in plans, sections, and elevations.
4.2.6 Drawing Indices. Where BIM authoring platform supports it, drawing indexes should be derived from a model-driven schedule.
4.2.7 Model Objects. Model objects shall contain IFC parameters and associated data applicable to building system requirements. These elements shall support the analytic process include size, material, location, mounting heights, and system information where applicable.
4.2.8 Construction Administration. The Lessor shall utilize model geometry and extract graphical information for generating construction administration documents from the Project BIM (RFI’s, Directives, Bulletins, and Change Orders, etc). The Lessor shall record as-built conditions in BIM as part of the final delivery to USCIS. Refer to Section 3.5.
4.2.9 Submittals: Submittal drawings, calculations and analysis shall be extracted from the coordinated BIM
4.2.10 Elements, objects and equipment shall be tagged with unique identifiers.
4.3 Types of Model Elements. Model elements shall be derived from the following sources:
4.3.1 Manufacturer’s Model Elements. Elements created by and acquired from manufacturers often have more information than is prudent to keep in the BIM model; the appropriate level of detail should be retained for the design element. However, embedded performance data shall remain for analysis and specification purposes.
4.3.2 Custom Created Model Elements. Custom model elements that are created must utilize appropriate BIM Authoring tool templates to create custom elements. Custom models components need to be assigned as a part and part of a family or group.
5.0 Section 5 - Ownership and Rights in Data
5.1 Ownership. The Government has ownership of and rights at the date of Closeout Submittal to all CAD files, BIM Model, and Facility/Site Data developed for the Project in accordance with FAR Part 27, clauses. The Government may make use of this data following any deliverable.

7.0 Definitions
7.1 The following definitions apply specifically to the USCIS BIM Requirements.
7.2 “Model”: A digital representation of physical and functional characteristics of a facility or a part thereof, comprised of “Model Elements” with “Facility/Site Data”.
7.3 “Model Element”: A self-contained element with a unique identification, whose behavior and properties are defined by Facility/Site Data and software processes. Model Elements can represent a physical entity, such as a pump or a concrete wall, and range from the simple to the complex.
7.4 “Facility/Site Data”: The non-graphical information attached to objects in the Model that defines various characteristics of the object. Facility/Site Data can include properties such as parametric values that drive physical sizes, material definitions and characteristics (e.g. wood, metal), manufacturer data, industry standards (e.g. AISC steel properties), and project identification numbers. Facility/Site Data can also define supplementary physical entities that are not shown graphically in the Model, such as insulation around a duct, hardware on a door, content of conduit, or transformer properties.
7.5 “Workspace”: A collection of content libraries and supporting files that define and embody a BIM standard. A workspace includes BIM libraries such as wall types, standard steel shapes, furniture, HVAC fittings, and sprinkler heads. It also contains sheet libraries such as print/plot configurations, font and text style libraries, and sheet borders and title blocks.
7.6 “IFC”: Industry Foundation Class, a standard and file format used for the exchange of BIM data; see www.iai-tech.org. Note: In the context of this attachment, IFC does not mean “Issued For Construction.”
7.7 The terms "drawings," "contract drawings," "drawing files," "working record drawings" and "final
Exhibit B-9
USCIS Building Information Modeling Requirements Page 6 of 6 record drawings" refer to contract drawings and Model which are revised to be used for final record as-built conditions.
7.8 “GUID”: Globally Unique Identifiers are automatically assigned by BIM software. GUIDs must be preserved through generation and regeneration of IFC deliverables so that a given object (space, equipment, etc) can be tracked properly.
