1 Generic AEC/FM BIM View Specification Architectural Design to Spatial Program Validation Reference GSA-001 Version 1.0 Status Final History Authors Document Owner Description Document created 1-Mar-06; v0.5 1-Jun-06; v0.9 1-Sep-06; v1.0 1-Nov-06 Richard See (Digital Alchemy) GSA Public Building Service Only part of information which is created by architects is needed for GSA s internal analyses of Conceptual Design Submissions. This Building Information Model (BIM) View Definition specifies the subset of the architect s BIM that must be submitted to GSA at Concept Design Submission milestones. This primary audience for this specification is software vendors creating BIM authoring applications that will be used to create such BIMs. Architects and Engineers (A-Es) creating such models are encouraged to review the GSA BIM Guide for end user instructions on how to create such models and what objects and information is expected. BIM models conforming to this view will generally be created by design architects using architectural BIM authoring applications. Models will be submitted as.ifc model files structured according to the industry standard IFC 2x or 2x2 schema (see These models will be uploaded to the GSA Project Information Portal at GSA project managers will then load the models into various internal software applications to perform design analyses. BIM in CAD CAD Documents Native CAD-BIM File(s) IFC File (GSA View) Current Process GSA Doc Review + Automated Analysis and Validation Process Visualization Model Integrity & Completeness Space Program Performance Others to be defined Version 1 of this BIM View is primarily focused on analysis of design performance relative to the GSA space program given to the architect at the outset of the project. While geometry and basic information is required for a primary set of building elements, emphasis has been put on properties of building spaces. It is anticipated that future versions of this IFC Model View will expand both information and object requirements to support other analyses such as: early design based cost assessment, early design based energy performance simulation, and LEEDs simulation. GSA would prefer to work with other organizations with similar requirements to develop industry standard Views for these requirements. Our approach to specifying an IFC Model view has been pragmatic. Our intent was to extend the existing Coordination View defined by the Implementer Support Group (ISG) in IAI because this view has been implemented in the architectural design applications most commonly used in North America. Our extensions are specific to Space objects in the IFC BIM. This document uses the official IAI View Definition Format version

Overview Spatial Program Validation done for and by building owner organizations involves the building owners' staff or consultants performing an assessment of the degree to which the building design meets all of the building owner's space requirements, as defined in the architectural program for the building. Such an assessment will, of course, be done by the design team as well. This building owner assessment can be viewed as a crosscheck of design performance in this important area. Spatial program validation during concept design is focused on the following things: A Pre-Check of the building model for valid model structure and for completeness (relative to what is required in the building owner's BIM Guide for Spatial Program Validation) Measurement of space areas, by space type and occupant Assessing and documenting differences between space areas provided in the design and what is required in the space program for the building --- by space type and occupant Assessing and documenting differences between the design and requirements in other areas (e.g. space proximity, floor location, etc.) Design issues discovered through these analyses, are communicated back to the building designer for resolution before the design will be accepted by the building owner.

4 Process Map [PM] for Spatial Program Validation Page 3 of 10 Some building owner/property management organizations, like US GSA, Statsbygg, and Senate have been requiring BIMs that meet the requirements of their respective BIM Guidelines for a few years now. This project will update BIM requirements for Spatial Program Validation (a.k.a. GSA BIM series 02) in concert with requirements for: Energy Performance Analysis (GSA BIM series 05) Circulation/Security Analysis (GSA BIM series 06) Quantity Takeoff and Cost Estimating (GSA BIM series 07) The MVD which integrates all of these requirements and enables 4 types of analysis on one BIM submission from the building designer is called the 'Concept Design BIM 2010.' Several building owner/property management organizations, including US GSA, Statsbygg, and Senate, will begin requiring submission of BIMS that satisfy these exchange requirements beginning late in 2010 or early in Their intent is to use consultants and/or analysis applications to perform the target analyses in order to provide feedback to the design team. The motivation for this process is to ensure better design of buildings --- designs that deliver all of these owner organizations' spatial program requirements.

5 Process Map [PM] for Spatial Program Validation Page 4 of 10 Specification of Process Concept Design Phase Spatial Program Validation [1.1] Develop the Concept Design BIM [1.2] Address BIM Guide Requirements [1.3] Check BIM Against BIM Guide Requirements The architects or designers will use an approved or certified BIM authoring application to create a Building Information Model (BIM) that will be used by the building owner organization for spatial program validation. The architects or designers must then extend/expand the BIM to address the requirements defined in the building owner organization's BIM Guide for spatial program validation. The final step before submitting a BIM to the building owner organization is for the architects or designers to check the BIM for conformance to the building

6 Process Map [PM] for Spatial Program Validation Page 5 of 10 [1.4] Submit Concept Design BIM owner organization's BIM Guide requirements. This could be done manually, but will most likely use a model checking application like that Spatial Program Validation plug-in to the Solibri Model Checker (SMC), developed in the US GSA BIM program. When the architects/designers are satisfied that both the spatial program and BIM Guide requirements have been met, they will submit the BIM for review by the building owner organization. [1.5] Initiate Design Validation After receiving the BIM from the architect, the building owner organization's design management team will initiate a design analysis process in order to ensure an optimal design in this case, from the points of view of design performance relative to spatial program requirements defined by the building owner organization at the outset of design. This analysis may be done inhouse, by specialists within the building owner's organization, or it may be contracted out to a consultant. [1.6] Pre-Check BIM The BIM will first be checked for correct model structure (i.e. structured as specified in the IFC BIM standard model schema) and for completeness (i.e. includes all of the information required in the ER_Spatial_Program_Validation_(concept) exchange requirements. Exceptions will be reported in a standard format. [1.7] Report Pre-Checking Results After ensuring that all of the pre-checking criteria have been checked (i.e. space geometry and data sufficiency), the building owner organization's specialist or consultant will return the checking results, including their comments, to the building owner organization's design management team. [1.8] Review and Comment Pre-Check Results The building owner organization's design management team will review the prechecking results, decide which of the reported issues must be resolved, and document these for discussion with the architects. [1.9] Check BIM for Spatial Program Conformance After all of the pre-checking criteria are met, the building owner organization's specialist or consultant will check the BIM for conformance to Spatial Program requirements. Results will be reported for interpretation by the building owner organization's design management team.

7 Process Map [PM] for Spatial Program Validation Page 6 of 10 [1.10] Review Spatial Program Validation Results The building owner organization will review the Spatial Program Validation checking results, decide which of the reported issues must be resolved, and document these for discussion with the architects. [1.11] Report Spatial Program Design Issues to be Resolved Real design issues are then discussed with the architects for resolution in the next design iteration. [1.12] Update Spatial Program to Address Program Issues Spatial Program issues will sometimes be resolved by the building owner organization's Spatial Programming team -- through adjustments to the Spatial Program, instead of changes to the design. [1.13] Design/Property Management Sign-Off At some point in this iterative design cycle, the building owner organization's design management team will approve the concept design with a final set of comments. [1.14] Update Design/BIM Design/Property Management Final Comments The architects or designers will then update the design to address final comments from the building owner organization's design management team. [1.15] Coordinate Owner Review After signing off on the Concept Design, the building owner organization's design management team will schedule reviews with their upper management and/or by tenant organizations that were significant in driving the spatial program for the building.. [1.16] Present to Building Owner The architects or designers will then present to the building owner management for approval. [1.17] Sign/Send Building Owner Comments The building owner's design management team will be responsible for securing the owner's approval and final comments. These will be addressed by the architects or designers before final concept design submission.

With all approvals and contingent approvals addressed, the architects or designers will make the final Concept Design submission to the building owner, including the final Concept Design version of the BIM. [1.20] Approve Transition to Design Development After verifying all the requirements for final submission have been delivered, the building owner's design management team will give approval for the design team to proceed to the next phase of design = Design Development.

Project Stage 0 Portfolio requirements 1 Conception of need 2 Outline feasibility 3 Substantive feasibility 4 Outline conceptual design 5 Full conceptual design 6 Coordinated design and procurement 7 Production information 8 Construction 9 Operation and maintenance 10 Disposal Overview Please ensure that you have read the process mapping document PM_Concept_Design_BIM_2010 Spatial_Program_Validation_v1.2.doc before proceeding with this exchange requirement. The scope of this exchange requirement is the exchange of sufficient information to support performance assessment of the concept design --- relative to the building owner's Spatial Program requirements provided to the designers at the outset of the design process. The exchange requirement assumes that a building model is developed by the project architect, using a BIM authoring application capable of capturing and including in the BIM, sufficient information to support this performance assessment. It is anticipated that the building model will provide context information about the project including project units of measure, coordinate systems, etc. As described in the Process Map document for this IDM, GSA, Statsbygg, and Senate Properties have been performing such Spatial Program Validation on significant projects since early The 'Concept Design BIM 2010' will expand BIM requirements in this area --- in support of expanded/improved Spatial Program Validation, beginning in Q or early in GSA/Statsbygg/Senate Properteis will either perform these analyses internally or will contract specialists in Spatial Program Validation. Submission of BIMs including the information defined in this exchange will be mandated by GSA, Statsbygg, and
