6 1. Introduction 1.1. Purpose of Document BIM Submission Guideline 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 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.

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. Last Saved Model or Last Saved View Copyright 2010 Building and Construction Authority. All Rights Reserved. 5

11 Checking and approval from the regulatory agencies is based on the Last Saved Model, together with the Last Saved View of site plans, floor plans, elevations and sections submitted. Therefore, QPs are to ensure that the following items are checked upon submission: a. Maximum extent is saved for each drawing view; b. No hidden objects or annotations; c. Any link (3D model or BIM saved in other file) that is considered part of the submission is bind as a single integrated BIM; d. All other external references, irrelevant drawing layers, objects, annotations, draft work and construction lines, which are not part of the constructed building elements, are to be removed or purged upon submission; and e. No propriety fonts are used for annotations and all the fonts should be legible; and f. All objects and annotation in each phase were displayed in the last saved view Model for Addition and Alteration Works/ Re-submission (URA)/ Amendments The same BIM model (with changes incorporated to comply with the requirements) should be used in resubmission (i.e. no shifting of spatial coordinate system in the re-submitted model). The revised submission should be indicated clearly in the name of BIM file submitted, following the format at Section 2.4. For any plan of alteration or addition to an existing building, or, re-submission for regulatory approval, all the building objects or elements should be demarcated clearly by colours in Table 4 (in accordance with SS CP83 Part 5): Table 4 Colours used for A&A project Colour Usage Magenta Proposed elements Cyan Existing elements Yellow Deleted elements Any building works which are to be deleted, removed or demolished must be shown in dotted lines on the plans and presented in a manner that can be easily identified or distinguished, as shown in Figure 3.

13 3. High-Level Modelling Requirements (Optional) BIM is typically defined by a hierarchy of objects that contain the most intelligence to catalog the physical and characteristics of design and construction. The 3D modelling as practiced in the industry today normally contains only the 3D geometric objects, which comprises the foundation of BIM, but lacking in a wide array of information associated with each of these building elements and systems. For instance, walls are created using the application s Wall Tool, slabs using the Slab tool, and so on. This section is not intended to prescribe a step-by-step method to create 3D BIM, but to highlight best practices in creating 3D BIM enriched with information of objects or building elements BIM Objects and Properties In BIM environment, there are a few items that QPs should understand and are advised to follow: a. Objects and elements should be created using the designated toolset in BIM application. For example, Slab tool should be used to draw floor slabs only, but not the walls and columns. In cases where such tools are not available, or they are limited in some way (e.g. some applications cannot create sloped beam), the QPs should create a generic object that can be assigned the correct Building Element type. The ability of BIM applications to manage components and spaces with complex geometric shapes varies, thus QPs are advised to work with their vendors to understand the limitation and workaround, if any; b. For a multi-storey building, the objects and building elements, such as wall and column, should be split into level and drawn on floor-by-floor basis. These elements should not span more than one storey and should be trimmed to the bottom surface of the elements above (e.g. beam, ceiling, floor slab, etc); c. Objects are defined by their own properties or attributes. For example, wall objects must include the interior and exterior property. Most BIM applications will incorporate this, either as shared parameters or add-on module, which may require the QPs to set the property value in some cases. Please refer to respective vendor s documentation for instructions on how this property is set; and d. In some BIM applications, certain properties of objects and building elements are set using layers. For instance, separation between exterior Copyright 2010 Building and Construction Authority. All Rights Reserved. 8

14 and interior walls is done using layers. QPs are encouraged to consult their respective BIM vendor about drawing layer strategies that will support drawing production and the BIM requirements outlined in this submission guideline, and if or how these can impact the object properties. Note: This section only applies to any BIM applications that use layers as the primary mechanism for filtering and structuring content Spaces and Zones Space is also a 3D object in BIM and normally represented in plan drawing view with a room tag (Figure 5), while several spaces of similar function can be grouped to form a zone. QPs are advised to follow the best practice recommended below: a. The space is typically defined by the inside faces of its bound building elements (e.g. walls, floors and ceilings). To align with the outer face of the exterior walls (in accordance with URA requirements for GFA calculation), QPs have to define the external boundary lines of either the rooms or unenclosed spaces (e.g. balconies and terraces), using the special tools provided by the BIM applications. QPs should consult the vendors to learn the recommended method for creating space objects; and Note: QPs must ensure that space object geometry is updated to maintain its alignment with the surrounding walls, floors or ceilings, if these space-bounding elements are moved. b. Spaces should be defined and modelled with a vertical extent from the finished floor to the finished ceiling. If the spaces (e.g. balcony and terrace) are unbounded by physical elements, the height should be set equal to the height of adjacent spaces at the same building floor. Note: A typical modelling error is to model the spaces with zero height. Copyright 2010 Building and Construction Authority. All Rights Reserved. 9
