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 BIM-
eSubmission, 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.
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.

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.

The respective

necessary
All drawing views of your project must be compiled into one single DWF/PDF file for
BIM-Submission1. 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 software2, 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.
Page 10 May-2010, v100409b BIM–Submission Guide Book (Structural)
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.
BIM–Submission Guide Book (Structural) May-2010, v100409b Page 11
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”.
Page 12 May-2010, v100409b BIM–Submission Guide Book (Structural)
� 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.

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.

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.
Page 16 May-2010, v100409b BIM–Submission Guide Book (Structural)
� 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
BIM–Submission Guide Book (Structural) May-2010, v100409b Page 17
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” sub-
task 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.
Page 18 May-2010, v100409b BIM–Submission Guide Book (Structural)
� 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.

1.14. 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.

Minimum Information Required
• Project Grid• Boundary Lines• Reference Datum Point
with Northing/Easting/ Reduced Level
See Section 1.3, 1.4 and 1.5
This step is usually identified by the
Structural Engineer after discussions with Architects
The information here is provided by the
Engineer and this step is quite iterative; structural
member size, location & properties are subjected to changes based on
Design & Analysis
If the Architectural BIM did not set
Structural identifier to the Structural
members, you may
have to manual create them
