Construction Project Risk Control
Insurance
Contractor’s liability insurance Workers’ compensation Employers’ liability Commercial general liability Automobile liability Owner’s liability insurance Usually general liability insurance Management protective liability insurance Professional liability insurance Property insurance Project owner’s obligation
Construction Project Risk Control
Major measures
Improved procurement method to minimize implementation risks Safety programs to reduce on-site accidents Strict construction measurements to confine environmental hazards Various insurance to reallocate risks Bond company involved to share risks with owner and contractor
To To To To To avoid risk remove/reallocate risk share risk reduce risk mitigate damage caused by risk
Construction Project Risks
List of risks
Planning and selection risks Contract formation risks Entity formation risks Entity management risks Site risks Resource risks Environmental risks Technology risks Communication risks Expectation risks
Construction Project Risk Control
Improved procurement method
Performance based procurement Construction management / management contracting Contractor prequalification in competitive bid Contract negotiation after bid opening Partnering or building long-term relationship
Risk Assessment Techniques
Cause-consequence analysis
A blend of fault tree and event tree analysis Based on both deductive and inductive logic The risk level of the system can be established by calculating probabilities of various consequences with the probabilities of various events
Risk Assessment Techniques
Fault tree analysis
Used to identify the causal relationships leading to the undesirable event Based on deductive logic Can be qualitative or quantitative
Risk Identification
To locate and identify the potential risks existing within the system or in the environment Methods
Previous statistical data Previous experience Survey Brainstorm …
Construction Project Risk Control
Safety programs
On-site safety management program including owner, contractor, sub contractor, etc. Regulatory safety control by government bodies Safety control and education by professional organizations, i.e. OSHA, BG, HSC, etc.
High Medium Low Low Mediuຫໍສະໝຸດ Baidu High Severity
Risk Control
To identify, select, and implement measures that can be applied to reduce the risk identified and evaluated during the previous phases Measures
Project Risk Identification
Methods
Survey or brainstorm
Applicable for small project
Systematic approach
Component analysis Process analysis Participant analysis Project objective analysis Project environment
Risk Assessment
Basic procedure
To clarify the risks which have significant or measurable impacts on project To analyze the consequences of the risk’s occurrence To evaluate the severity of the impact caused by the risk To prioritize risks by calculating risk impact, and then formulate possible improvements or preventive measures
Project Risk
Any loss, damage, or undesirable event that may impact the project to be accomplished on time, under budget, and to required quality standard
Risk Assessment Techniques
Frequency
Frequency/severity diagram
Used to evaluate the impact of risks and prioritize the preventive measures Based on consequence evaluation and probability calculation Can be semiquantitative or quantitative Risk value = Severity x Frequency
Construction Project Risks
List of risks
Financial risks Completion risks (cost) Completion risks (time) Completion risks (quality) Payment risks Project administration risks Force majeure risks Political risks Currency risks

Contractor classification and prequalification Review of contractor’s financial sustainability Assurance of contractor’s performance and behavior
Methodologies
Qualitative To distinguish risks as high, medium and low level Semi-quantitative To prioritize risks in relation to one another Quantitative To measure, calculate and analyze the value of risks and the impact
Risk Assessment Techniques
Event tree analysis
Used to illustrate the sequence of the outcome after the occurrence of a selected initial event Based on inductive logic Mainly used in consequence analysis
Risk Assessment
Concept
A scientifically based process of evaluating risks and the likelihood of exposure to those risks, and then estimating the resulting impact
