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

regulatory agency

reserves the right to

verification, where

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.


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.


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”.


� 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.


� 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


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.


� 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.

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.

Copy Structural Members

START

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

Modeling Workflow (New Project)

See Section 1.7


You need to verify

Project Grid and Boundary are set to

the True coordinates,

orientation and Elevation Datum.

Otherwise you may have to perform task

in Section 1.3, 1.4

and 1.5
