4 GSFIC BIM Guide
Introduction
Objective of this Guide
The purpose of this guide is to aid Architects and Engineers (A/Es) in their Building Information Modeling (BIM) efforts related to design and construction of GSFIC managed projects. This release series 01 addresses BIM for Design requirements only. Subsequent releases will deal with requirements for BIM for construction and BIM for facilities operations and maintenance.
Wherever BIM is required as a deliverable the A/E shall refer to and comply with the requirements of this guide. Also where the design professional bid solicitation states that BIM capability is preferred and the design professional contract is awarded on the premise that the A/E is BIM enabled and shall provide a Building Information Model as part of the deliverables; the requirements of this guide shall apply.
This guide describes the standards that all BIMs for GSFIC construction projects shall abide by. BIM deliverables shall be verified by the GSFIC Design Review Group. During the verification process BIMs shall be reviewed according to the items outlined in this guide in four main areas. The Building Information Model will be used for:
1. Building Constructability Review 2. Building Life Safety Components Review 3. Clash Detection 4. Checking Building Model Quality (Third Party BIM Validation1)
BIM as a Supplement
A Building Information Model is a placeholder for information about a building or facility. The Building Information Model begins with the owner's space/program2 requirements and is made up of whatever information needs to be collected regarding a site or a building. This information includes but is not limited to program spaces, structural elements, ductwork, electrical installation, fire protection, occupancy, energy consumption, etc.
The BIM deliverable does not replace the standard project deliverables stated in section 2 of the GSFIC Design Professional Contract(s) (CM/GC, DBB and DB).
For all projects where BIM is required it will be in addition to all current design submission requirements set forth in the design professionals contract and design review process guide. Most of the required submittals will overlap as illustrated by Table 1.1.
This deliverable should be seen as a tool to aid GSFIC's review of the design submissions.
Design Submittal Consistency
GSFIC encourages project teams to gain efficiencies through creating the required 2D drawings from the BIM. The goal is for the BIM submission and design documents submission to be consistent.
1 The third party referred to here is the GSFIC Design Review Group. 2 Project Development File or Program that has been approved by the Office of Planning and Budget, State of Georgia.

5 GSFIC BIM Guide
GSFIC will review the BIM submissions to ensure compliance with the requirements defined in this Guide and with those defined by specifications for the Industry Foundation Class (IFC) BIM standard:
Requirements and Deliverables
Model Ownership: The Building Information Model constitutes an instrument of service as defined by the Design Professional Contract section 2.1.2.1 (2.1.4.1 in Design Build (DB) contract). Therefore all items pertaining to instruments of service as set forth in section 2.1.1 (2.1.4 in DB contracts) shall apply to the model. This means that as the building Owner; GSFIC shall also have ownership of the model and can make it available to the using agency3 at any time as required. Refer to Appendix C of this guide for Instruments of Service section from the Design Professional Contract.
The BIM deliverables required in the Preliminary4 and Final design submission include:
A single BIM file in IFC 2x2 format (preferred) or IFC 2x format. BIM file(s) in the native format of the BIM-authoring application(s).
GSFIC is aware of issues related to converting BIM files to IFC format from the native file format and therefore acknowledges that the IFC format is not completely robust at this time. A/Es are therefore required to document any known issues with IFC BIM at the time of upload. The list of issues should be submitted as a word document to accompany the BIM file.
A/Es should use the appropriate BIM tool to create objects. For example, "Wall" objects should be created using a "Wall" tool. If an object is not directly supported with an appropriate BIM tool, A/Es should consult with their BIM-authoring vendor to determine the best way to model those objects (see section 3 of this guide). Objects created using the wrong tool set in a BIM authoring application become problematic when exporting to an IFC BIM because they will be exported with the wrong object types.
How to use this Series 01 GSFIC Building Information Model Validation
This series is divided into 4 major sections:
Section 1: Constructability Review BIM This section describes the overall objective and process for submission of the constructability BIM. It describes the high-level modeling requirements for creating the BIM and for the IFC BIM submission.
Section 2: Life Safety Review BIM This section describes how and where to create the space boundaries and describes how to assign the required spatial information to space objects.
Section 3: Building Elements This section describes the required building elements for model validation and other GSFIC reviews.
Section 4: BIM-analysis Rules This section describes the BIM-analysis rules that the A/E submissions will be checked against. This section also highlights special cases that may affect the BIM analysis. A/Es should read carefully through this section to understand these cases.
3 State agencies and other State entities for which GSFIC provides construction management services. 4 Preliminary design submittals include programming, schematic and design development phases.

6 GSFIC BIM Guide
1.0 BIM for Building Constructability Review
As required by the GSFIC Design Review Process Guide (GSFIC _DRPG), constructability reviews performed by the Design Review Group check for conformance to:
GSFIC policies and guidelines Applicable building and engineering codes and standards Completeness and coordination of documents
1.1 Required Constructability Review Information
Constructability reviews of all projects are performed prior to advertisement for bids (Design-BidBuild delivery method) or issuance of a Component Change Order (CM/GC or Design-Build delivery method) at all phases of design: Programming, schematic design, design development and construction documents. CM/GC delivery methods will likely include component change orders (CCO) in-between these phases.
The Building Information Model will be used to perform constructability reviews based on items listed in Table 1.1 of this Guide for each design phase.
This table has been developed from ASTM E 1804-02 which is currently referred to in the GSFIC Design Professional Contract as a guideline for information which is generally developed at each phase of the design.
The information in the highlighted fields is not required to be represented in 3D, however these items are still required as part of the building information submittal package.
1.11 Topographic and Property Line Surveying
It is encouraged that Surveys be provided in electronic format and at a minimum include 3D topographic information including paving and retaining walls. The file(s) shall be in a format that allows for importing into the A/E's BIM Authoring software.
All land surveys must be tied to the State's GIS GA State Plane West, NAD83 (1991) coordinate system and USGS datum. The surveyor shall provide electronic files that clearly define the project site and include accurate x/y/z coordinates on all survey items. The file(s) must be in a format that allows for importing directly into the State's GIS system. Survey points must "land" within the State's GIS datum within the margin for error that is normal in the industry.
1.12 Existing Conditions
All existing conditions needed to explain the extent of work for renovation, alteration and addition projects shall be modeled.
1.13 Energy and Sustainability Analysis
In instances where energy modeling is a required deliverable, the A/E shall use early energy modeling tools integrated with the BIM Authoring software to develop comparative energy analysis. Modeling parameters shall be based on local climate data and actual site conditions.

2.0 Building Life Safety Components
A construction permit is issued by the State Fire Marshal's Office for all state projects. Certified state fire inspectors under GSFIC employ perform fire marshal reviews of GSFIC managed projects for the purposes of issuing construction permits. Fire marshal reviews check for compliance with life safety codes as outlined by the Rules and Regulations of the Fire Safety Commissioner 120-3-3. The model shall include the information listed in Table 2.1 of this guide for the relevant permits at each phase of construction.

The Life Safety Review will utilize the spatial components of the building information model.

One of the purposes of validating the Building Information Model is to efficiently and accurately assess design performance, relative to Life Safety Code requirements.
13 Documents in the shaded portion of Table 2.1 shall be signed and sealed by the corresponding A/E

10 GSFIC BIM Guide
Certain items such as the smoke control analysis will not be reviewed via the Building Information Model. Such submittals and reviews will be done using traditional methods.
2.2 Required Spatial Information for all Projects
Spatial information will be used for assessment of conformance to applicable life safety and building codes. It will also be used for design assessment relative to the spatial program issued by the Using Agency to the A/E at the programming constructability review phase. See section 1 of this guide.
Consequently, modeling spaces accurately is one of the most important tasks in creating BIMs. Space objects are normally represented in plan drawing view with a data tag (e.g., name, number, etc.).
A/Es should ensure that all names (e.g., space name, occupant organization name) match established using agency conventions. Where no using agency conventions exist A/E shall defer to Appendix D of this guide.
At a minimum, A/Es are required to have the objects that constitute a Life Safety Plan in a valid 3D geometry representation: Full-Floor Space, Wall objects (with Door objects and Window objects) Slab objects, Column objects and Beam objects. In addition, spaces must include the following information:
Space Area (Net or Gross as required for occupant load calculation per NFPA 101 Table ) Space Name Space Number
These spaces might also be grouped into a Zone, for visualization and analysis purposes (e.g., to differentiate private vs. public zones, for thermal simulation calculations).
Note that the boundary is to the inside face of all of the walls, and that the columns are deducted from the net area.
2.2.1 Example of Modeling a Space Object Figure 3 demonstrates how net area is defined and the resulting impact upon the occupant load calculations.

12 GSFIC BIM Guide
3.0 Building Elements
3.1 Modeling Precision
The system of measure for modeling GSFIC new construction projects is the United States Customary System (English Units). The dimensional tolerance should be 1/8 inches. The coordinate system origin for BIM files submitted must be located logically and in close proximity to the building geometry (e.g., at a grid intersection). This origin must not be moved during the course of the project since most objects in an IFC BIM use relative placement, which traces back to the project coordinate system origin.
3.2 Retaining Original Global Unique Identifiers (GUIDs)
One cornerstone of the IFC BIM schema is a unique identifier assigned to each object in the model. These IDs are used in cross-object references, relationships, and to enable tracking of what has changed in a model between two states or versions. All software applications that support export of IFC BIMs are able to generate unique object identifiers called Global Unique Identifiers (GUIDs). If a BIM-authoring application provides the option to keep the original GUID, this option should always be selected.
BIM-authoring applications generally allow the user to identify a model subset (or filter) when exporting to an IFC BIM. In some cases, this is done by exporting only the layers that are currently visible in the BIM-authoring application. This allows users to export only the parts of the model relevant to the purpose of the export. Please refer to the BIM-authoring application vendor's specific instructions on how to filter the objects to be included in the export to an IFC BIM.
Regarding a BIM submission to GSFIC, all non-BIM related layers, objects, text styles and other elements not used in the Final Concept design configuration shall be purged before submission. For example, early phase "what if" scenarios that have been abandoned but were left in the model should be deleted from the native file before the complete native model file(s) and exported IFC BIM are generated.
When uploading IFC BIMs in either .IFC or .IFX formats, users should not compress the files (e.g., using WinZip) unless explicitly agreed otherwise.
3.3 Handling Multiple BIM Versions
A BIM exists as a digital model of the building at a given point in time. It may be produced by a number of parties using various software tools. BIMs submitted to GSFIC should only contain the current state of the design. Submissions should not contain alternative or abandoned design schemes. Several versions of the BIM may be created during the design process. BIM versions may be published for specific uses by various project stakeholders. In each case, the BIM version normally needs to contain only the subset of information that is relevant to the intended user at the current phase of the project.
Each design alternative included in the Preliminary Concept design submission to GSFIC shall be supported by a separate BIM in IFC format that contains only the information relevant to the subject design alternative. Similarly, Final Concept design submission to GSFIC shall be supported by a BIM in IFC format containing only information relevant to the Final Concept design.

13 GSFIC BIM Guide
3.4 Model Containment Hierarchy
The model structure (or containment hierarchy) of BIM is normally generated by the BIM-authoring application. Users have little if any possibility to influence it. In situations where the user can define the model containment hierarchy, it should be structured as in the IFC BIM standard. Typically, spaces and building elements are contained in a building floor, building floors are contained in buildings, buildings are contained in a site, and a project can contain one or more sites. In the submission to GSFIC, the site object is optional (in which case the building is contained directly by the project) and the building floor object is also optional (in which case spaces and building elements are directly contained by the building).
This containment hierarchy can be summarized as follows:
Project o Site Spaces Building Elements Buildings (same as below) o Buildings Building Floors Spaces Building Elements
Spaces can also be members of one or more Zones (e.g., daylighting, HVAC, or even an organizational department). See section 2 for more detail on Spaces and Zones.
In general, the BIM-authoring application will manage this for the A/E, but it is important to be aware
3.5 Model setup
Each discipline is to have its' own file(s) There is to be one master (or CENTRAL) file, linking in all disciplines' models All phases to be within one file, and to be separated into phases of work All model objects to be set to accurate dimensions (not overridden dimensions) and real-
world dimensions to be used (not nominal dimensions) All drawing sheets should be generated from the model
o Exception: Highlighted exclusions to Table 1.1
Wall objects must include the "interior or exterior" property as defined in IFC. The BIM-authoring application will include this in export to IFC, but the user may be required to "set'" the property value in some cases. Please see vendor documentation for instructions on how this property is set.
In order to ensure that all instances of each object type in the BIM are complete and meet the requirements defined in this Guide, users are advised to use one of the BIM-authoring applications listed in appendix E of the appendix supplement to this guide, or independently validated as compliant with these requirements.

Appendix A (File Clean Up Process)
1. Make all objects within the file visible. 2. Check the 0,0,0 origin. If there is no absolute coordinate system in the software application
you are working in, make sure you leave crosshairs in the file representing the 0,0,0 origin.* 3. Purge the model of any unused elements, if the software application has that feature.
(Remove demolition plans and different versions/design alternatives.) 4. Audit (check and fix any errors in) the file, if the software application has that feature. 5. Detach all links (external references) to other files. 6. Delete or detach any images. 7. Designate and save a specific view for export to Navisworks. 8. Run internal clash detection (interference checking) and provide list of any unresolved
clashes at the time of upload. 9. Save clash report and upload with model submittal. Check filename and send. Once the new file is created, make sure the name is correct (according to GSFIC file naming standard), and upload file to the GSFIC Web Portal (E-Builder). Note: Whenever updates are provided upload only files that have been modified and provide the list of changes. *Define how coordinates are shared see Appendix F: BIM Execution Plan.
Appendix B (BIM-Analysis Application Example)
Navisworks Manage
GSFIC Design Review Group will utilize Navisworks Manage to check building information models for coordination between architectural and engineering disciplines, to identify clashes and also to simulate and optimize scheduling.
