Building Information Modelling (BIM) awareness Seminar for Civil Engineering and Development Department on 6-Mar-2014 Speaker: Ir. Francis LEUNG - Founding Chairman of HKIBIM HKIBIM Website: www.hkibim.org HKIBIM Facebook: https://www.facebook.com/hkibim

1. The Hong Kong Institute of Building Information Modelling

2. BIM Awareness Seminar
 Introduction to BIM
 Current and future trend
 Use in civil engineering and its benefit

3. Introduction of BIM
 Building Information Modelling is the development and
use of a multi-faceted computer software data model to
not only document a building design, but to simulate the
construction and operation of a new capital facility or a
re-capitalised (modernised) facility.
 建築信息模擬是使用電腦數據模型但不單是把建築設計信
息保存，更是模擬建造和營運新建或改造的建築設施。

57. Public Consultation & Approval
 The Sequence was shown to:
 District Council
 MTR Station
 Gov’t Depts: Police, Transport Dept., …
 Neighbour developments
 Smooth process of approval
 Minimum negative concerns
 No irrational objection

58. Footbridge Demolition

59. Footbridge Demolition (Revised)

60. BIM Process
 Through BIM modelling, the bridge demolition schemes
were modelled, reviewed and revised for perfection
 Animations shown to public are coordinated schemes
 New ideas were updated to BIM to review and confirm
for construction

87. The Workflow

5. PS: Complete Box

before Rainy Season

88. When HyD works on the alignment, do
they know there is a 6-cell Box Culvert?

89. If they know there is a 6-cell Box Culvert,
have they even thought of re-alignment?

90. Or just leave it to downstream?

91. How do they see VALUE of project?
Best Alignment or Best Overall Value?

92. How do Engineers see EXCELLENCE?
Solution to solve complicated problem or
NO PROBLEM?

93. Can the alignment be revised?

94. Is it because it takes too much effort and cause
too much troubles so CANNOT be revised?

96. BIM Workflow
 Before start working on the alignment, the 6-cell Box
Culvert and all other site constraints are in the
Information Model (IM)

97. BIM Workflow
 Alignment is easily built

98. BIM Workflow
 Implication due to the alignment is immediately seen

99. BIM Workflow
 Options can be shown in parallel for comparison

100. BIM Workflow
 Alignment can be revised with little effort

101. BIM is not about the model
It is a process of
