Introduction 1.1. Purpose of Document The objective of this Document is to assist qualified persons (QPs) in developing BIM models to meet new requirements of Building Information Model (BIM) submission. It describes the requirements and guidance for creating BIM with specific object types, associated properties and presentation format to the following regulatory agencies for visual processing: a. Building and Construction Authority (BCA) b. Urban Redevelopment Authority (URA) c. National Environment Agency (NEA) d. Public Utility Board (PUB) e. Fire Safety and Shelter Department (FSSD) f. National Parks Board (NParks) g. Land Transport Authority (LTA) h. Housing and Development Board (HDB) i. JTC Corporation Note: The respective regulatory agency reserves the right to reject and request for necessary correction of any required deliverables or formats that do not meet the requirements. 1.2. Scope This submission guideline contains a list of requirements written in a concise form to guide QPs in preparing BIM submission to the above mentioned regulatory agencies. It is by no means an exhaustive list of requirements of the building works which must be complied with when making a building plan or planning submission. The items in this Standard Guideline may also be amended or revoked when new written laws come into force. For more information or enquiries on the specific submission requirements, please consult the appropriate regulatory agency above. CAD vendors and retailers have developed their own application dependent user manuals. These user manuals should be read carefully as this Document cannot take into account all the special features of individual BIM application. For any submission requirements mentioned in the Appendices that require customisations to a certain extent, QPs are also advised to make reference to the training materials distributed or to consult the respective software vendor for any enquiries on the application. If there are contradictions between this submission guideline and vendor’s instructions, BCA BIM team shall be contacted for clarification. Copyright © 2010 Building and Construction Authority. All Rights Reserved. 1 BIM Submission Guideline for Architectural Discipline 2. General Requirements 2.1. Deliverable Format QPs are required to submit BIM saved in the file format, as summarised in Table 1, upon submission to each of the above mentioned regulatory agencies. Note: All BIM e-submission through CORENET e-Submission System is limited to not more than 100MB per file per submission. If the file size is larger than 100MB, QPs are requested to deliver in CD-ROM to the respective agency. Table 1 Accepted file format in BIM submission for regulatory approval Regulatory Agencies Accepted File Format for BIM Submission Remarks 1) All BIM submissions to URA a. A single BIM in the native format 1: For Major project (e.g. phase i. Autodesk Revit (.rvt); or condominium development), ii. Graphisoft ArchiCAD (.pla) separate BIM native files can be submitted for each building block. b. A single light-weighted file format, as However, a SITE BIM file linking published from the similar BIM native file: all the buildings should be i. DWF (.dwf); or submitted. ii. PDF (.pdf) 2) BIM submissions to other a. A single light-weighted file format, as The respective regulatory agency regulatory agencies: published from the similar BIM native file: reserves the right to request BIM a. BCA; i. DWF (.dwf); or native file for verification, ONLY if b. CBPU; ii. PDF (.pdf) necessary. c. PUB; d. FSSD; e. NParks; f. LTA; g. HDB (if any); and h. JTC All drawing views below should be compiled in a single DWF/PDF file. Refer to Appendix C for detailed steps in publishing to DWF/PDF. a. Plans, elevations, sections, layout views or sheets (refer to Appendix A for specific requirements from each regulatory agency); and b. A 3D model. 1 These are based on the IFC certified BIM applications that are commonly used by the local industry and are prepared for BIM submission to-date by going through a series of pilot runs with the authority. The accepted file format may be expanded when new BIM vendor(s) has met the requirements and ready for local BIM submission. Copyright © 2010 Building and Construction Authority.

Model Scale All 3D CAD models or BIM submitted for approval have to be drawn in real size as built (1:1) in metric scale. 2.3. Model Orientation and Site Configuration The site, building model or its adjacent buildings should be drawn in the real orientation or spatial coordinate system and with reference to Singapore Standard Datum (>100M), rather than project reference level at zero ground. 2.4. Standard Naming of File and Drawing Views File naming convention below (as modified from SS CP83 Part 3) should be used for all project files submitted: Sample: Project ID Author Zone Version User-defined M L P 1 _ A - 0 1 _ A - Table 2 Naming convention for each 3D model or BIM file submitted Name of Field Indicators Description Project Identification User defined field for the project Author A- Architect C- Civil engineer E- Electrical engineer L- Land surveyor M- Mechanical engineer Copyright © 2010 Building and Construction Authority.

Annotations and Dimensions Except for 3D model view, all other submitted views such as plans, elevations and sections should be indicated clearly with the necessary annotations, dimensions, scalebar and north point, as specified by the respective regulatory agency in Appendix A. Within each of the model view, QPs are also required to include the related name of view, as shown in Figure 2. Figure 2 Sample of new erection project with name of plan indicated at the bottom 2.6.
