Construction Project Procurement and Risk Management

SECTION –A
(This section has three questions. Answer any two full questions from this section)
Question 1 [Note: To attempt this question, answer all 3 parts 1(a), 1(b) & 1(c)]
Question 1 (a): By assuming a Design-Build project delivery arrangement, you are required to
outline any four key differences between (a) public sector procurement of a bridge contractor;
and (b) private sector procurement of architectural consultancy services for a Hospital project.
Question 1 (b): A large international construction company has recently secured a major urban
development project in overseas. By assuming a procurement officer role in this main
contractor organisation, you are required to identify five relevant criteria for selecting a
specialist subcontractor for this overseas project. Also, suggest a weighted scoring
subcontractor selection template and illustrate with an example of choosing a suitable
specialist subcontractor (Assume that you have received competitive proposals from 3
subcontractors).

Answer 1(b)

Question 2 [Note: To attempt this question, answer both 2(a) AND 2(b)]
Question 2 (a): You are the safety & risk auditor for a multi-use tunnel infrastructure project
procured by a “Public Private Partnership” arrangement. This is an urban side underground tunnel
infrastructure, which include: utility lines such as electricity, gas, water, and sewer. By means of a
‘preliminary hazard analysis’ (i.e. with suitable assumptions):
(i) identify four health hazards/ safety risks for the maintenance works in
underground/ confined space;
(ii) prepare your basic recommendations for those hazard/ risk items
(4 marks)
Answer 2(a)
Identified Hazard/ Risk Basic/ Initial Recommendations
Hint: Your recommendations could be in the form of acceptance,
recommended controls, design specification or requests for more
detailed assessment

 Egress and Access
 Communications
 Explosive or flammable atmospheres
 Combustible materials
3. Flooding  Training

Question 2 (b): Assume that you are the risk management consultant for an Australia based offshore oil
and gas facility. The top management has decided for comprehensive refurbishment of
rest rooms and dining areas in this high hazard offshore facility. You are assigned to
provide independent consultancy for safety and technical risks in this refurbishment
project. In this regard, prepare a basic bow-tie analysis report of a typical risk event that
might occur in this refurbishment project.
(6 marks) Answer 2(b)

The risk event in this project that has been considered for answering the question 2(b):
Pre-event:
Root causes / Mechanisms Preventions/ Escalation Controls
Occupancy
Cabin size
Cabin Design
Storage space
Sanitary facilities
Corridors
Mess/Dining Rooms
Risk of sleep disruption
There should be adequate space for free
circulation space for the occupants
The comfort is always related to the design and
the space made available after designing
Sufficient storage space would allow some
space for the individuals to roam around
The facilities should include hygiene and
sanitation
The corridors should have enough space to
move
Enough and bulk space for dining or eating
Post-event:
Consequences / Impacts Mitigations / recovery controls
Two-berth cabins with washroom facilities,
toilet, -suite shower, and shared between the
cabins
Allowing spaces can have the single berth
cabins
Four birth cabins should not be preferred
Cabin size should have following
specifications:
 900 mm among the births facing each
other
 600 mm among the nearest and single
birth obstruction
 1000 mm to join two or more aisles
Proper planning
Proper designing
Proper establishment
Proper design
