1. GENERAL REQUIREMENTS Building Information Modeling (BIM) is the process of generating and managing building data during its life cycle. Typically it uses three-dimensional building modeling software to increase productivity in building design and construction. The process produces the Building Information Model (also abbreviated BIM), which encompasses building geometry, spatial relationships, geographic information, and quantities and properties of building components. (Abstract from http://en.wikipedia.org/wiki/building_information_model). Therefore, to enable BIMeSubmission, all projects drawings will need to be prepared and presented in 3- Dimension (3D). This Chapter outlines some background, and the specifications required to deliver your project in BCA s BIM esubmission format. To jump-start your effort in BIM, BCA together with the Software Vendors, has developed a BIM esubmission Template that you will help manage your project regulatory submission requirement. You can obtain a copy of this template from BCA, or from your software vendor. Most BIM software is more complex than conventional 2D software; we strongly recommend that you equipment yourself with fundamental skills through authorized training sites before you embark on your BIM journey. Step 1 Step 2 Step 3 Step 4 Step 5 Check Latest Submission Template Version Modeling, Detailing & Presentation Prepare Submission Views/Sheets Modeling, Detailing & Presentation Submit to Regulatory Agency CORENET Environment BIM Environment CORENET Environment Figure 1 - Steps in Preparing the BIM Project for Submission The diagram above gives a high level 5-steps process flow of how BIM esubmission can be carried out in a BIM environment. The rest of the section in the chapter will guide you to making this possible with your BIM software. BIM Submission Guide Book (Structural) May-2010, v100409b Page 7

1.1. Drawings Deliverable Format For every Project BIM-eSubmission, QP only needs to prepare 2 Packages for submission as opposed to what you would do in current practice; today if you have 50 drawings files associated to your project, you will be encrypting all these documents individually for submission into CORENET. For BIM-eSubmission, these 2 packages are a 3-D model (aka BIM native file) of your project, accompanied by a Light-Weight File (either DWF or PDF). This Light-Weight File is a static equivalent of your BIM Native File. This diagram below illustrated conceptually, the differences between current esubmission with 2D documents against BIM esubmission. Current esubmission Method BIM-eSubmission Method Table 1 sums up todays approved file format for BIM-Submission. Currently, the Regulatory Agency do not required the BIM native file to be submitted for Approval, but you are advice to keep a backup of this document as the Authority reserves the rights to request for it anytime, should they decide to verify the information presented in the equivalent Light-Weight File. All formal endorsement and approval by the Regulatory Agency will be done on the Light-Weight File submitted (either DWF or PDF) instead of the BIM Native File. The 2 primary reasons are a) The Light-Weight File is non-editable and static, that means its content cannot be tempered. And their formats are generally accepted as neutral. b) Singapore s National Archival has guidelines in place to ensure information captured in documents / drawings can be archival and retrieved. Note all BIM-Submission using CORENET esubmission System is limited to 100MB per file for each submission. If the file size is greater than 100MB, alternative means would be to submit via CD-ROM to the respective agency. Page 8 May-2010, v100409b BIM Submission Guide Book (Structural)

Table 1 - Accepted File Format in BIM esubmission for Regulatory Approval Ref Regulatory Agencies BIM Submission File Format Remarks 1 Regulatory Agencies - BCA A single Light-Weight File published from the equivalent BIM native file, either - DWF (.dwf) - PDF (.pdf) The respective regulatory agency reserves the right to request BIM native for verification, where necessary All drawing views of your project must be compiled into one single DWF/PDF file for BIM-Submission 1. If you are not familiar on the procedure to export DWF (or PDF) you need to seek assistance from your respective software vendors, or software manual to use this feature. This task may require a 2-step action to publish the document for submission a) Publish plans, elevations, sections, layout and / or sheet views (refer to XXX for the specifics to each regulatory agency) b) Publish the 3D model, which needs to be merged into the published file in Step (a) to produce a single PDF / DWF file. 1.2. Project Model Scale When you are modeling your Project in the BIM software 2, your project model must be presented in Real-World measurements. That means if a wall in its physical state reads 5metres by 3metres, you will draw that wall in the BIM software as 5metres by 3metres. If you intend to use millimeters as the base unit of measure, in your model within the software, then all objects modeled must be in millimeters. Do note that most BIM software has a utility to setup the project unit of measurements. If you not familiar on how to do this, please consult your software vendor for assistance. See also Chapter xxx. Project Basic Composition for related information. 1 As of 1 st May 2010, the composition of the light weight file includes Architectural Drawings and Structural Drawings. According to Building Control Act (Chapter 29) Building Control Regulations 2003, Part 2, Submission and Approval of Plans, there is no role for PE to sign on Architectural Plans. If this act is to be strictly enforced, BIM Structural esubmission will require 2 DWF (or PDF) files to be submitted, one for Building Plans, and the other for Structural Plans. 2 BCA currently acknowledges Autodesk Revit Structure, and Tekla Structure as BIM-enabled software for Structural Engineers. This list is not exhaustive and will progressively include additional software to the list. BIM Submission Guide Book (Structural) May-2010, v100409b Page 9

1.3. Site Configuration / Layout This requirements is an additional task that is now required for any BIM Project Submission. You will need to present at least the followings in this section, to ensure consistent information across different engineering discipline documents, The Project Grids The architecture project grids must be re-produced into the structural project correctly The Project Site Boundary It must coincide within the structural project When you model the project site into the BIM software, you need to ensure they are positioned in its real world coordinates and the site orientation must be aligned to True- North. You can obtain this information from your Architect; this information is available from Land Surveying Plans, and you can overlay them into your project. But if you cannot have this information, you would need to use the paper plans that you have and input those coordinates, bearing and distance into your project. Take note that most Land Surveyors Plans units of measurements are in meters whereas Architectural Plans are in millimeters. If you are fortunate enough to obtain the building plans in the form of a BIM document, you only need to attach this document to your working structural document; most BIM software will allow you to copy over the coordinates and orientation already established in the building plans model so you do not need to perform this task of Site Setup. Otherwise, you will have to perform this task ensure the right position and orientation are established. This task needs to be completed in 2 steps a. Setup consistent project grids and site boundaries between engineering disciplines. The steps to perform this task is generalized as follows Create a Site Plan View in your current BIM environment Attach Building Plan Site View as reference to this created Site Plan View Use tools (or features) in your BIM software to create project grids You are expected to key-in the inter-grid values instead of copying from the building plans, to ensure there are no discrepancies in project grid values You can now copy the project site boundaries across to your structural project b. Allocate project position to the its equivalent real-world coordinates You need to know which boundary point is your datum. This is usually represented with Northing, Easting and Reduced Level. Next you have to associate this boundary point datum to the real world values in Northing and Easting; this process is synonymous to moving your entire project to the equivalent X and Y value in AutoCAD environment. For most BIM software, there will be a feature in the software to associate these readings to a pre-defined point on the project space virtually, without having to physically moving the entire project. Page 10 May-2010, v100409b BIM Submission Guide Book (Structural)

1.4. Project Model Orientation In almost all circumstances, QP / PE would prefer to work on their project orientation aligned to a horizontal line, something that they can easily associate for visualization. Thus in this context, the term that the industry has adopted is known as Project North. For all your project document views in your submission file, you can align them to Project-North, except for Site Layout. Site layout must be presented in True-North, which is aligned to the real-world orientation. In short, the North-Arrow symbol can only be pointed up and not elsewhere. Most BIM software supports this setting between Project-North and True-North in your project, usually configured within Project Setup. That means you do not need to physically rotate your project model, and the software will manage between both orientations virtually; you can toggle between these 2 orientations as and when the needs arises. If you are unfamiliar with this feature within your BIM software, please refer to your BIM Software manual, or contact your Software vendor for assistance. This task is typically a subsequent task after you have completed Site Configuration / Layout documented above. This task generally follows the sequence below if the reference file has not been set with the right orientation. Setup your Site Plan drafting view to read True North Using one of the boundary lines, create a reference line to represent the actual bearing of the project file. You can read this value from the site boundary lines; presented in degree, minutes and seconds. Note you probably need to use your boundary point datum as the starting reference to this orientation Once done, activate the command from within your BIM software, the tool to rotate the entire project to this newly created reference line. This will complete this task. For all other views in your BIM software, you need to ensure the viewing properties has been set to read Project North before you start any modeling or annotation works. 1.5. Project Model Elevation Datum Another element in project setting lies with Elevation View. Project Elevation Datum must be align to Singapore Standard Elevation Datum (>100m), and not placed on ground zero. Again this is typically a set-up function you need to configure in your BIM software; you do not need to physically move the project to actual elevation but virtually established this value in the environment setup. If you are problem setting up this requirement in your software, you may refer to your BIM software manual, or approach your software vendor for assistance. Please note that the unit of measurements for Singapore Standard Datum is usually represented in meters whiles your project measurement units maybe in millimeters. To complete this setup, you will generally follow the steps illustrated here. This task is typically done on conjunction with Site Configuration / Layout. BIM Submission Guide Book (Structural) May-2010, v100409b Page 11

Note the Reduced Level readings on your Elevation Datum point. It is usually located at one of the site boundary points. Also note that your Site Plan elevation is usually a duplicated view of your ground-level drafting view. Otherwise, you may need to adjust this difference. Next, activate the function within your BIM software to associate the reference point in your project to the actual elevation datum value. This step will complete this task. You can now switch to your project elevation view, and change the readings to show according to Singapore Standard Elevation Datum. 1.6. Standardized File Naming for BIM Submission This section suggests adopting SS-CP83, Part 3 to manage naming your file for submission if you do not have a standard within your organization. This section can be applied to your Light-Weight File as well as the Native BIM file. The followings describe briefly how this can be done. For full details on how this standard, you need to refer to SS-CP83 documents. The file naming convention is divided into 5 parts, where Part 1 to Part 4 is delimited by an underscore _ and they are mandatory fields. Part 5 is optional but it is recommended that you use it to give better meaning to the file. This is then followed by the file extension which represents the file format. The illustration shown below is a sample to naming a file. To decipher the meaning of the file name, see Table 2. Table 2 Abbreviations to use in File Naming Convention Name of Field Number of Characters Indicators Description Project Identification 4 (minimum) User defined field for the Project. Any meaningful abbreviations to describe your project. Author 2 A- Architect C- Civil Engineer E- Electrical Engineer L- Land Surveyor M- Mechanical Engineer N- Equipment Supplier Page 12 May-2010, v100409b BIM Submission Guide Book (Structural)

Name of Field Number of Characters Indicators Description T- Telecommunication / Signal Engineer V- Other Disciplines X- Contractor Zone (or Block) 2 NN Where N: zone or Block Number Eg. 01 for Block 1 A1 for Zone A1 -- For all blocks Version (Revision / 2 A- 1 st Submission Submission) B- 2 nd Submission C- 3 rd Submission User-defined (Optional) 3 (minimum) User defined code for in-house applications (Optional Field) 1.7. Standardized Drafting View Names in Project In almost all BIM software, you can present the 3D-Model that you have done, in a 2D perspective. These are commonly called Views ; some examples of these are Top Views, Sectional Views and Elevation Views. These views are automatically generated from the Model; you do not need to draw them in these views. For every BIM esubmission document, there will be composition of views and sheets with the relevant annotative information, so that downstream users such as Contractors and Manufacturers can utilize them for their works. To facilitate unambiguous understanding to these views for regulatory approval as well as information sharing among project members, we need to adopt a standardized definition to these views. This section explains a standardized format that must be adopted strictly within your BIM esubmission document. Failing which, your submission may be rejected which could delay your project. This section is divided into 2 main sub-sections, a. Renaming Views in project Submission (View Naming) b. Renaming Sheets in project submission (Sheet Naming) VIEW NAMING This naming pattern is divided into 3 parts, each part is delimited by an underscore _. All parts to this naming convention are mandatory and you are advice to adhere strictly. The illustration shown here is a sample to naming a view. To decipher the meaning, see Table 3. BIM Submission Guide Book (Structural) May-2010, v100409b Page 13

Table 3 - Naming Convention for each Drawing View Field Name Number of Characters Indicators Description Discipline 4 ARCH Architectural Discipline STRU Structural Engineering Discipline MEPS Building Services Engineering Displace OTHS Others, for future use View SP Site Plan 2 (Type of FR Roof Plan View) FP Floor Plan FE Elevation FX Building / Project Section 3D Project 3D View DT Details sectional views LV Layout View (only for textual data information) User Defined 4 (minimum) This part can be use to describe the view meaningful. Some suggestions are list below but not exhaustive 1st Storey 2nd Storey 3rd Storey Nth Storey Lower Roof Roof Mezzanine N Basement N Elevation X or X Elevation Section N Architect s Declaration Engineer s Declaration QP s Declaration Where N = Storey Number Where N = Mezzanine number Where N = Basement Number Where X = Directions (eg. East, West, North, South or 1, 2, 3, 4) Where N = Section Number Page 14 May-2010, v100409b BIM Submission Guide Book (Structural)

SHEET NAMING This naming pattern is divided into 2 parts, each part is delimited by an underscore -. All parts to this naming convention are mandatory and you are advice to adhere strictly. Field Name Sheet Number User Defined Number of Characters 2 (minimum) 4 (minimum) Indicators Description Sheet Number 15. This must tally with the sheet 1 5 reference on the Title Block This part can be use to describe the Sheet meaningful. Some organization associate this part with the Drawing Number / Reference in the Title Block, followed by a descriptive text to explain the purpose of the sheet. 1.8. Last Saved Views Checking and approval from the regulatory agency will be based on the last saved views of your project model, including all peripheral views and sheets such as Site Plans, Floor Plans, Elevations and Sections. QP/PE is advised to ensure that the following actions are exercised before exporting to the Light-Weight File and doing BIM-submission. Maximize your all project s view extent before saving No hidden objects or annotations Any external links such as attached 2D drawing files, 3D model and Project Segment saved in other file, which is part of the submission must be bind into a single integrated Model All other external and internal references objects, regardless of drawing layers, annotations, draft work and construction lines, that are inside the Project Model and has no bearing for the submission purpose, must be removed or purged before doing BIM-Submission. Do not use propriety fonts for annotations and all the fonts must be legible For regulatory approval, no furniture needs to be presented in the model, unless they have implication to regulatory matters. All objects and annotation for each phase must be displayed in the last saved view. BIM Submission Guide Book (Structural) May-2010, v100409b Page 15

If you project is an A&A Works, ensure the relevant phase have been activated with the right colour-coding (reference SS-CP83). Ensure you have all the Project Basic Composition views in your project. See chapter 1.11 for information. Your BIM Native File may contain more than what is needed for submission but the Light-Weight File must contain only the listed composition 1.9. Addition and Alteration Projects If you are working on Addition and Alternation (A&A) projects, you are required to demarcate your project model accordance to SS-CP83, Part 5. You need apply colour identifier (see Table 4) to all the objects in your model before doing BIM-Submission. In most BIM software, you do not need to physically change the colour of these objects; it can be configured virtually through Phase Settings (or View Configuration). Do seek assistance from your software vendor on how you can activate this feature in your software. To present you re A&A project according to the SS-CP83 guidelines, any parts of the building project that will be demolished, you have to represent this information on your project model using Dotted Lines on the plan view. This dotted line must be presented explicitly. A sample of such presentation is illustrated in Figure 2. Table 4 - A&A Projects Objects Colour Coding Colour Usage Remarks Magenta Proposed Elements All additional works on existing structure needs to be added as new objects in your model Cyan Existing Elements All existing parts of your structure needs to be updated in your BIM repository with this status Yellow Deleted Elements Any parts of your project that has to be removed, before new additional works can be carried on existing structure, must be indicated. Because your project eventually will be printed for task such as construction site inspection or discussion, the colour mode may be difficult for communication; typically printed in black-and-white. As such, you much include clouding in your project, over the areas that will be affecting by the A&A works. Therefore, the task here will require 2 subtasks, as illustrated below. a. Applying Colour coding to your project model b. Clouding area/zone of A&A works Page 16 May-2010, v100409b BIM Submission Guide Book (Structural)

Figure 2 - Sample of A&A Project / Project for re-submission (2D and 3D Views) COLOUR CODING This task can generally be executed in the following sequence with most BIM Software Highlight all objects in your model and update its phase (or status) properties to Existing Zoom in to the area that needs to be updated with additional works Select objects / members in the project model, and update their phase (or status) properties to demolished Your view will now hide these objects/members in the project model. You should also be able to switch the current view to present the colour coded view according to SS-CP83. When you have completed with the above, you can now add new objects/members to the structure. If your view has been set to SS-CP83 colour-coded view, these newly added members should be displayed in magenta colour. CLOUDING AFFECTED AREA This task can only be carried out once you have completed the Colour-Coding subtask outline above. The following sequence illustrates some process that some BIM Software may adopt to achieve this task. Toggle to one of the plan view in your project that is affected Switch the View Properties to display SS-CP83 colour codes In the View Properties, you should have additional options to display only demolished items. Select this option to do this. You will notice your current view will only show objects that are has colour yellow, and nothing else. Use the cloud tool available in most BIM software and circle around these yellow colour coded objects. BIM Submission Guide Book (Structural) May-2010, v100409b Page 17

Next, in the view properties, toggle back to display only Existing and New Works. You will notice all yellow colour coded objects has disappear and your clouds now overlay the project drafting view. You can repeat the above sequence for any views (plans, elevation and sections) to highlight all affected area with clouding. 1.10. Project Re-Submission In the event your BIM-Submission has clarifications, or you are required to perform Re-Submission, you to need to use the same revision of the Project Model that you initially submitted to the respective Agencies, and reflect the differences / changes with colour identifier accordance to Table 4. Once you have done this, only then should you publish it to the Light-Weight File for BIM-Submission. Note that the file name will have to be updated for this re-submission and you need to refer to chapter XXX for reference. Figure 2 above illustrates a sample of how a re-submission project model may look like. Again, cautions needs to be emphasized for line types presentation, and it must be explicitly identifiable. 1.11. Project Basic Composition Within your BIM software, you should see an Explorer-Like Browser (or Navigator), that describe the composition of your BIM project, such as Views, Sheets, Layouts and Libraries. But not all items in this Navigator are required for the BIM-eSubmission. You only need to export the fundamental compositions illustrated in the following section to the Light-Weight File (DWF or PDF). This file is then digitally signed and transmitted over CORENET esubmission to complete the BIM esubmission process. The list suggested here is subjected to addition for future needs. You are advised to check for revisions periodically. Do note guidelines identified in this document in order to ensure smooth approval process. Any non-compliance with the guidelines can result in rejection, which will delay approval process.

Modeling Workflow This section suggests a modeling workflow within your BIM software. Note the information is generalized to a certain degree. When you need to execute it within specific software, the details will vary from one platform to another. Thus, you may need to engage your software vendor or IT support engineers to work on the details. There are 2 workflow outlined here a. New project Modeling in your BIM Software b. A&A project Modeling in your BIM Software This section assumes you want to model existing structure and incorporate new works over it. If you decide not the model the existing structure, it is advisable to follow conventional 2D practices. This workflow will not be presented here. BIM Submission Guide Book (Structural) May-2010, v100409b Page 19
