Services Administration GSA Public Buildings Service PBS Office of the Chief Architect OCA established the National 3D 4D BIM Program http www gsa gov bim As part of this program OCA has evaluated an array of 3D 4D BIM applications on a number of capital projects Since circulation issues are of extreme importance for the correct functioning of most federal buildings and especially courthouses circulation validation is a useful aspect to review early and thoroughly OCA has been working with a number of PBS offices BIM vendors the building industry leading research institutions and professional organizations to establish requirements for an application that supports circulation validation assessment This guide is a result of the work the GSA BIM team has done to ensure that high quality models will be submitted for Circulation and Security Validation GSA has been working with a number of BIM authoring software vendors to ensure that architects and engineers A Es are able to comply with the new GSA spatial requirements using a broad range of available software via the Industry Foundation Classes IFC open standard GSA is also testing and validating these requirements on pilot projects with A E teams across the nation Objective of Circulation and Security Validation using BIM The overall purpose of Circulation and Security Validation using BIM is to efficiently and accurately assess design performance relative to GSA courthouse circulation design requirements In the past GSA used to validate circulation programs using visual review and redlining of circulation paths By using BIM models GSA can automate the circulation validation process to ensure that all designs in the Concept Design phase adhere to the circulation requirements set forth by US Courts Design Guide Requirements and deliverables For the accurate assessment of circulation conditions A Es are required to generate a valid 3d geometrical representation produced in a BIM authoring tool for all the spaces identified in the design proposal For all those spaces identified in the BIM model having a GSA net area over 9s f A Es need to provide the following BIM object types and required attributes Space containing space name space ID number space security levels and optionally additional circulation use Elevator containing space name space ID number and space security levels executive summary Circulation and Security Validation iv GSA BIM Guide Series 006 www gsa gov bim Stair containing space name space ID number and space security levels Ramp Ramp slope Wall no specific attributes required Door no specific attributes required In addition to the listed requirements for individual space objects A Es must also provide the full building floor containing space names and space numbers for every floor defined in their design and they should consult their regional GSA project team and OCA to determine if additional requirements are necessary for their submission The deliverables required by the GSA Circulation Validation Tool in the Concept design stage includes A single file containing the BIM model exported to IFC 2x2 format or IFC 2x3 format The purpose of this guide is to help A Es prepare the correct development of their BIM models regarding Circulation Validation for courthouse design The following points highlight some of the most important requirements of BIM modeling for Circulation Validation If the following points are not properly defined by A Es when modeling the Circulation validation process of their BIM models will be incorrect A Es must accurately define spaces using the names included in the Circulation Validation Naming Convention see Appendix A A Es should use the appropriate BIM tool and objects when creating their models For example when modeling stairs the stair assembly needs to be created using the stair tool so that the object can be properly interpreted When A Es need to model objects used in the circulation validation assessment but whose geometry is not supported by the appropriate BIM tool A Es will need to consult with their BIM authoring vendor the best way to model those entities Conclusion With Circulation Validation GSA expects to help A Es to efficiently evaluate their designs and ensure their compliance with circulation guidelines defined for courthouse design The
