ABSTRACT

Building Information Modelling (BIM) is an approach in which utilise a 3D parametric modelling as a primary technology. The approach brings many advantages and has attracted many players in Malaysian Construction industry and has led the industry to develop a roadmap to strategize the implementation. The roadmap is important to coordinate many activities amongst the industry groups working with adopters of BIM in Malaysia. The aim of the study is to support the development of BIM national roadmap by providing the data of the stakeholders' Interest of BIM implementation at the industrial level. Research methodology used in this research is qualitative in nature by engaging a workshop. The workshop was organised by Construction Industry Development Board (CIDB) Malaysia. In the workshop, six groups of stakeholders were formed to provide data and information regarding to the stakeholders' interest for BIM implementation. The stakeholders were academics, vendor & BIM consultant, facilities management, contractor & quantity surveyor, design consultant and public agency. Result from the workshop shows that the stakeholders interest basically tied to the three main objectives of construction delivery which are the quality, cost and time. Combining all the interests, 47 factors of interests were identified with some of them are overlapped between one stakeholders to another. Based on the occurrence that takes place during the discussion, the most discussed factors are the accuracy of BIM data, reduction of delivery time and improve understanding of the project information.

CHAPTER 1

INTRODUCTION

1.1 BACKGROUND OF RESEARCH

Building Information Modelling (BIM) is now become natural phenomenon in

construction industry in Malaysia. BIM utilize 3D parametric object tools which give

more advantages to the user. In order to maximise the benefit of BIM, at the national

level a roadmap is important as one of the strategies to implement BIM. The

importance lies on the need to coordinate many activities amongst the industry

stakeholders working with BIM adopters in Malaysia.

On July 24th, 2013 at CIDB Malaysia headquarters in Putra World Trade

Centre, Kuala Lumpur the first meeting was held to establish BIM Steering Committee

at the national level, which was officiated by the Chief Executive Officer of CIDB

Malaysia, Dato' Sri Jr. Dr. Judin Abdul Karim The meeting was chaired by Dato' Jr.

Hj Salehudin Bin Mohd Isa, Senior Director of Cawangan Pengurusan Projek

Kompleks, Jabatan Kerja Raya (JKR) Malaysia and attended by industrial participants

representing Persatuan Arkitek Malaysia, Board of Engineers Malaysia (BEM), Royal

Institute of Surveying Malaysia (RISM), PRiMA, Sime Darby Properties, Economic

Planning Unit (EPU'), Academician from Local Universities etc. The establishment of

the steering committee is to undertake a huge and critical task to oversee and manage

the adoption and implementation of BIM in Malaysia.

1.2 PROBLEM STATEMENT

The key objective of the roadmap is to coordinate the many activities amongst

the industry groups working with adopters of BIM in Malaysia, which unless

coordinated, have the potential to be overlapping, or a duplication of resources,

technically different and incompatible, and not comprising a complete enough solution

that will benefit the Malaysian Construction sector. Many private organisations and

government agencies have interests in the National BIM Roadmap and will identify

stakeholders to ensure a representative position is taken across the industry in

Malaysia. This will not only include direct BIM users, but also take into account Local

Government, the need for coordination with the Infrastructure sector, government

agencies such as major facility procurers - PRiMA, Health, EPU - and agencies

responsible for Geo-spatial data, land information etc.

The roadmap consists of four major elements which are Stakeholders' Interest,

Stakeholders' Objectives, Key milestone and KPI platform. The Stakeholders' Interest

are crucial in the development of the roadmap as all the motivation, expectation and

problems associated with the construction industry and BIM are tied to it. Therefore, a

study must be conducted to explore and identify the stakeholders' Interest and was set

as the main.

1.3 AIM & OBJECTIVE OF RESEARCH

The aim of the study is to support the development of BIM national roadmap by

providing the data of the stakeholders' Interest and Objectives of BIM implementation

at the industrial level. The objectives of the study are:

1. To explore, appraise and systhesise relevant literature related to BIM with

specific focus on the concept, usage, implementation requirement and success factors

2. To explore, appraise and systhesise relevant literature related to roadmap

development with specific focus on the stakeholders' interest.

3. To explore and identify the stakeholders' interest'.

1.4 SCOPE OF STUDY

The scope of the study is important as a guidance to minimize the area to focus

on the research. For this research there are three main scope of study need to focus on.

1. Phase of Lifecycle - Construction Lifecycle

2. Level of Implementation - Operational Level

3. Stakeholders' Interest - Industrial Level

2.2 DEFINITION OF BUILDING INFORMATION MODELLING (BIM)

BIM is modeling technology and associated set of processes to produce,

communicate and analyze digital information models for construction life-cycle

(Steering Committee, 2013). In another view, R. Vanlande et al. ( 2008) state that

Building Information Modeling (BIM) is defined as the process of generating, storing,

managing, exchanging, and sharing building information in an interoperable and

reusable way. According to Gu & London (2010), Building information modeling

(BIM) is an IR-based approach that involves applying and maintaining an integral

digital representation of all building information for different phases of the project

lifecycle in the form of a data repository. From the other view, BIM refers to a set of

interacting policies, processes and technologies that generate a methodology to manage

the essential building design and project data in digital format throughout the building's

life-cycle (Succar, 2012). In addition in the book of BIM Handbook;

5

According to Eastman (2008) the 3D parametric tool has the following characteristic;

1) Consisting of a geometric definition and associated data and rules;

2) Geometry is integrated non-redundantly and allows for no inconsistencies. When

an object is shown in 31), the shape cannot be represented internally

redundantly, for example as multiple 2D views. A plan and elevation of a given

object must always be consistent. Dimensions cannot be fudged.

3) Parametric rules for objects automatically modify associated geometries when

inserted into a building model or when changes are made to associated objects.

For example, a door will fit automatically into a wall, a light switch will

automatically locate next to the proper side of the door, a wall will automatically

resize itself to automatically butt to a ceiling or roof, etc.

4) Objects can be defined at different levels of aggregation, so the user can define a

wall as well as its related components. Objects can be defined and managed at

any number of hierarchy levels. For example, if the weight of a wall

subcomponent changes, the weight of the wall should also change.

5) Object rules can identify when a particular change violates object

feasibility regarding size, manufacturability, etc.

6) Objects have the ability to link to or receive, broadcast or export sets of

attributes, e.g. structural materials, acoustic data, energy data, etc. to other

applications and models.

Based on the statement by Eastman et al. (2011), BIM is 3D Parametric

Modeling that gives a lot of benefit to the construction industry. This proved by the

other source, the US National Institute for Building Sciences has given a following

vision and a definition for BIM. According to Eastman et al. (2011), BIM is "an

improved planning, design, construction, operation, and maintenance process using a

standardized machine-readable information model for each facility, new or old, which

contains all appropriate information created or gathered about the facility in a format

usable by all throughout its lifecycle."

6

According to the National Institute of Building Science (2007:12) Building

Information Modelling (BIM) is defined as "a digital representation of physical and

functional characteristics of a facility and a shared knowledge resource for information

about a facility forming a reliable basis for decisions during its life-cycle." The

definition however, appears to be generic to include any digital technology as long as it

could contribute to form information on a facility. As further explained by Onuma in

Smith & Tardif (2009), a spread sheet of spatial data is a building information model

and if the use of alphanumeric data contained in the spread sheet is to simulate an actual

business process in the life cycle of a building, then a Building Information Modelling is

engaged. The generic definition of Building Information Modelling is also supported

by Jernigan (2007) by pointing out that the interactions of spread sheets with the

complexity and an interrelationship of organisation is also Building Information

Modelling.

Within the context of Malaysia, Haron (2013) has defined BIM as an approach

to building design and construction through modelling technology, an associated set of

processes and people to produce, communicate and analyse building information

models. The definitions sets a boundary to differentiate BIM with other technologies

such as 2D/3D vector based means of creating objects, and 3D surface modelling

which is used for the purpose of visualisation only, which carries no attribute to the

element and therefore complemented by the definition of Building Information Model

which is defined by Kymmel (2008) as digital representation of physical and functional

characteristics of a facility where the information is contained or attached to the

component of the model. In both definition, the 3D parametric tools is identified as

main BIM tools as has been defined by Eastman et al. (2011) earlier in this subchapter.

Meanwhile, at the national level, according to CIDB (2013), the steering committee has

established the definition to be used by the industry. They define BIM as Modelling

Technology and associated set of processes to produce, communicate and analyze

digital information models for the construction life-cycle.

2.3 BUILDING INFORMATION MODELLING (BIM) CONCEPT

BIM concept is differed with 2D Computer Aided Design (CAD). In the CAD

approach, the focus is given on the drawings production. Contrary with the CAD

approach, the focus of BIM is centred on the 3D BIM models. The models become the

main deliverables where they are first authored before project information can be

extracted from the model. Therefore, the project information are centralised and

coordinated within the same source of model and the model itself becoming the

database of project information (Hardin, 2009). The examples of project information

are the drawings, bill of quantity, specifications and etc. Since the project information

is sourced from the same model, they are all consistent and accurate where changes on

the model will automatically change the interrelated drawings and specification. Within

this approach, the heart of BIM lies on the use of 3D parametric tools. According to

Smith &Tardif (2009) the concept of Building Information Modelling is to build a

building virtually, prior to building it physically, in order to work out problems and

simulate and analyse potential impacts. The heart of Building Information Modelling

lies in an authoritative building information model.

According to Kymmel (2008) virtual building implies that it is possible to

practice construction, to experiment and to make adjustments in the project before it is

constructed. Virtual mistakes generally do not have serious consequences provided that

they are identified and addressed early enough so that they can be avoided in the actual

construction of the project. When a project is planned and built virtually, most of its

relevant aspects can be considered and communicated before the instructions for

construction are fmalized. It is like running a simulation of a construction project by

considering all aspects of the construction life cycle.

In terms of the types of information or data that can be derived within a

Building Information Model, generally, Elvin (2007) and Hardin (2008) explained that

a Building Information Model could provide 2-D and 3D drawing with non-graphical information including specifications, cost data, scope data, and schedules. Kymmel

(2008) on the other hand, categorised several types of information within Building Information Model based on the nature of the link between information and the model.

7

8

This pertains to all information that is part of, or connected to, the components as well

as the physical information inherent in the model itself such as size, location, etc. It is

important that all information required in making an actual analysis be available from

the BIM. The categories of information, as can be summarised from Kymmel (2008) is

as follows:

a) Component Information

Component information is the basic information contained in the 3D model file

where it provides visual information and resides in the nature of the model part

itself. Components in a 3D model also have specific locations in relation to an

origin and to one another. An example of component information is a wall with

material information or quantitative information such as part numbers.

b) Parametric Information

Parametric Information is information contained in the parametric object which

can be edited. It is embedded in the object and the model. Some of this

information can be graphical, while much of it can also be intellectual, such as

area, volume or material-32 related qualities, such as density (providing weight

based on the geometry of the object), R value, etc.

c) Linked Information

Linked Information refers to information that is actually not part of the model,

but is connected to the model through external links. Visible links can be

"flags" that will open a window or file when clicked to display that file.

Invisible links could be, for example, connections to a database with cost

information. When two files are linked, changes in one will result in adaptations

in the other linked file, and vice versa.

d) External Information

External Information refers to information that is generated separate from the

BIM, such as manufacturers" specifications of products. External information

may be linked to the model or remain autonomous. It is possible to provide a

reference to a catalogue without creating a link to an electronic file. Since not all

9

information will be available in a compatible format it may be necessary to keep

it accessible in printed form such as an external reference.

Elvin (2007) further added that another important feature of Building

information Modelling is how it creates an object-oriented database, meaning that it is

made up of intelligent objects, for example representation of doors, windows, and walls

which are capable of storing both quantitative and qualitative information about the

project. So while a door represented in a 2D CAD drawing is just a collection of lines,

in BIM it is an intelligent object containing information On its size, cost, manufacturer,

schedule and more. But BIM goes further by creating a relational database. This means

that all information in the BIM is interconnected, and when a change is made to an

object in the database, all other affected areas and objects are immediately updated. For

example, if a wall is deleted, doors and windows within the wall are also deleted and

all data on project scope are instantly adjusted.

To extend the application of Building Information Modelling to integrated

practice in construction, according to Eastman et al. (2008), the building information

model should be used as a building model repository. A building model repository is a

database system whose schema is based on an object based format. It is different from

existing Project Document Management (PDM) systems and web-based project

management systems in that the PDM systems are file based and carry CAD and

analysis package project files. Building model repositories are object based, allowing

query, transfer, updating and management of individual project objects from a

potentially heterogeneous set of applications. In this context, the integration occurs at

the level of data and could also integrate with other dimensions such as the time

dimension (schedule) and cost dimension, which are known as 4D and 5D modelling

respectively (Zhou et al., 2009; Koo & Fischer, 2000, Dawood & Sikka, 2007; Fischer

& Kam, 2001). This application would allow construction phases to be analysed early

in the design phase which as a result could support early involvement of the contractors in design development.

Figure 2.0 shows the concept of whole BIM process cycle. The BIM process

cycle is take place in every part of the project from the conceptual design till the

demolition process.

2.4 MOTIVATION FOR BIM IMPLEMENTATION

The BIM Industry Working Group indicates that there are substantial

organisational impacts through BIM implementation for all stages of the construction

process. (Arayici et. Al, 2011). BIM is another key aspect leading to similar improved

accuracy, design and construction is 3D visualisation. (BIMhub, 2012). The benefits of

using BIM is one of the motivation why our construction industry and government

eager to implement BIM. The implementation of BIM brings a lot of benefits. The

benefits are better communication of design intent, knowledge gap reduction between

junior and senior staff, reduced risk of losing project information process; it was

11

streamline, and time saving. The details of the benefits are further discussed in the

following subchapter as adcording 'to Haron (2013)

2.4.1 Communicate the Design Intent Better

All of the interviewees agreed that the implementation of 3D parametric

modelling tools as part of BIM has improved the communication of design intent that

takes place within and outside the organisational boundary. The improvement lies on

the 3D visualisation and drawings consistency where everyone involved has the same

understanding of what is being designed.

2.4.2 Reducing the Knowledge Gap between Junior and Senior Staff

The BIM implementation reduce knowledge gap between junior and senior staff

as compared to using the 21) approach alone. The main reason is the fundamental

nature of 31) modelling where each component is represented with digital 31)

objects that carry attributes and parametric, rules. The tools have assisted the junior

designer to understand every component that they are authoring by providing 3D

visualisation and the attributes that. need "to be assigned. In 2D approach on the

other hand, every

object is made of a collection of lines and requires the designers interpretation and

imagination to define what the object is. The 21) approach therefore requires a longer

technical site experience to understand each component and its attributes and thus

makes it difficult for the junior staff with a lack of experience. Furthermore, the 3D

modelling tool has enabled the junior staff to try and experiment with the design

which helps a lot in sharpening their skills and understanding.

2.4.3 Reducing Risk of Losing Project's Information

BIM help to keep the structure of the projects data and information in .a

digital repository.: somebody in charge is moving out, the newcomer can

simply refer to the BIM database and continue the job from there.

12

2.4.4 Process Streamline and Time Saving

In previous CAD-based process flows, one of the biggest challenges

faced by the industry is to ensure drawings consistency and clash free design.

The massive number of drawings that were produced individually in a project has

made document consistency and clash checking a very time consuming and tedious

process through the manual approach. Therefore, most of the time was spent on

documentation and checking rather than focusing on the aspect of engineering and

design. With the implementation of BIM, since the virtual 3D model is the source for

all drawings, design errors caused by inconsistent drawings are all eliminated.

Meanwhile, the clash checking process and Material Taking Off are taken

automatically by using the software which also shortens the time duration. As an

overall result, the time spent for documentation, checking and taking off material is

reduced significantly and the people can give extra focus to the aspect of

engineering and design. Thus, the company has managed to streamline the process

flow and save time.

CHAPTER 3

RESEARCH METHODOLOGY

3.1 INTRODUCTION

Research methodology is important and it is refer as the procedure to develop

the research. This statement had been explained by Fellows & Liu (2007), "research

methodology refers to the principles and procedures of logical thought process which

are applied to a scientific investigation." The procedure of the project had been

explored before the research start to ensure that the research achieved their goal. In this

research there are five stages of methodology used, there are;

First stage - Preliminary Study

Second stage -Area of focus andconcept development

Third stage - Research Design and Devôlopment

Fourth stage - Exploratory Data Collection

Fifth stage - Data analysis and validation

This five stages of research methodology will be explained further in the next

subsection. The figure below shows that overall stage involved in this research.
