Risk Managment Flashcards
(36 cards)
Examples of risk in a construction site
External risks - economic incertainty, inflation rates, legislation changes.
Financial Risk - excahnge rate changes, increased cost of borrowing
Site Risks - restricted access, planning difficulties, environmental issues.
Client Risks - lack of expereince,
Design Risks - inappropriate consultant team, poor team ethos.
Construction and delivery risks - adverse weather, asbestos, availablity of materials
Define Risk
Risk is defined as an uncertain event or circumstance that, if it occurs, will affect the outcome of a programme/project.
Define Opportunity
An uncertain event which should it occur will have a positive effect on the achievement of the construction project
Define an ‘Issue’
An event that has occurred and has impacted on a construction project OR an uncertain event that is no longer able to be controlled by the project (and requires escalation)
What is risk management?
Risk Management is the process of identifying, assessing, responding and reviewing risks associated with the delivery of an objective e.g. construction project.
Risk Management establishes a set of procedures by which risks are managed.

Why is Risk Management Important? What are the benefits of risk management?
Construction projects in their nature are inherently risky, they are unique, constrained and complex. All have time, cost and quality targets that must be met. Risk management reduces likelihood of cost and time overruns
Enables decision making to be made and an assessment of known variables that are available. Assigns contingency to reduce delays in getting paid.
What are the mitigation strategies for risk?
STARR
Risk Sharing – client and contractor share the risk. E.g. provisional sum (JCT).
Risk Transfer – transfer risk to the contractor
Risk Avoidance – try to avoid the risk e.g. don’t build on terrible ground conditions, Alternative design solution.
Risk Reduction – where level or risk is unacceptable – risks are mitigated to reduce risk e.g. conduct a site investigation.
Risk Retention – appropriate risk allowance identified in the cost plan to be reserved and managed by the employer.
How does the NRM deal with risk?
Risk management
- needs to be identified, assessed, monitored and controlled appropriately and effectively.
At the time of prepating a BoQ there will still be several risks to be managed by the client and thier team. This is called Employer’s residual risk exposure (aka residual risks).
The risk response will be either:
Risk transfer to the contractor
risk sharing by both employer and contractor
risk retention by the employer
Risk that can be designed out or avoided should have been addressed by this stage of the design development proces. If this is unacheivable, they will be dealy with using one of the above strategies.
It is recommended that separate allowances be made for each of the following:
Design development risks, Construction risks, Employer change risks, Employer other risks:
Describe the format of a risk register?
Typically include:
* Description of the risk
* The risk owner
* Probability of occurrence
* Impact of its occurrence
* Risk factors (probability x impact)
* Actions required
* Review date
* Status (open/closed)
What is a Risk Event?
An event that can be predicted to at least some degree, generally based on historical data or experience and making a decision according to the probability of a particular event occurring.
What is an uncertain or unforeseen event?
A random event that defies predictions
What are the stages of risk management?
- Identification
- Analyses
- Response
- Monitor and control
What is Quantitative Risk Assessment?
- Quantitative analysis: probability and impact are given a value and multiplied to produce an objective score.
What is Qualitative risk assessment?
- Qualitative analysis: describes and understands each risk to assess its likelihood and consequences.
- The purpose of qualitative analysis is to prioritise the risks in terms of importance, without quantifying (costing) them. This should be carried out during the first phases of the risk-management process.
What is the difference between Quantitative and Qualitative risk assessment?
Qualitative describes and understands risk in relation to likelihood and impact in a range from very high to very low, whereas Quantitative is probability and impact given as a value.
How risk is managed post contract?
Risk is managed in NEC ECC through early warning register, implementing change control and reviewing and updating risk allowance.
What is a risk management workshop and how is it undertaken?
Risk workshops are conducted to identify, assess and analyse the risks associated with the strategic brief. The following steps are undertaken.
1. Prepare the workshop – objectives, scope and agenda, participants, roles and responsibilities and logistics (venue, date, time & equipment).
2. Conduct the workshop – follow agenda and use various techniques to identify risk (brainstorming and SWOT).
3. Document the risk – in a risk register. Add description, probability and owner of risk.
4. Analyse the risk – determine their significance & implications through qualitative and quantitative analysis.
5. Plan the response – on how to address them STARR or acceptance of the risk.
6. Review the response – communicate workshop response and monitor and control.
In you initial cost estimate how much contingency did you hold? [amend]
At Initial cost estimates I provide a % against contruction risk and design risk, as these are unknown at this stage. For training facility this was at 5% using a previous similiar project to help decide on this %.
Employer risks are included in a risk register and are typical risks that can be quanitified (be it at a 3 point estimate and a larger range between min, ml and max).
- The amount included should reflect the risks and unknowns specific to the project.
- During early estimates when little information is available it is common to include a %
- This should reduce as more information becomes available and the unknowns decrease % will differ based on the type of project
How do you determine a risk allowance?
At early stages I can provide an early stage allowance. For example, for Armoury cost plan there was a 5% allowance of the total CAPEX cost for design development risk and construction risk.
This was determined by looking at previous similiar projects. In this case a armoury at RAF Lakenheath.
The Employer change and employer other risk was quantified from the risk register, at around 20-25%. This is then inputted into the Monte Carlo to produce an overall risk allowance.
What is the difference between risk allowance and contingency?
- Contingency is a sum of money for a future event or circumstance which is possible but cannot be predicted with certainty and is effectively an unknown outside of the risk register
- Risk allowances can be quantified and estimated via a risk register and the risk pot is drawn down from if and when the risk occur.
Please provide an example of risks associated with your area of business
For my role specifically there is optimism bias.
A typically risk for a construction project is asbestos being found, this is high probabiltiy because the buidings that are being refurbed were built before asbestos was banned in 1999.
Another example is risk of UXOs,
Both asbestos and UXOs can be mitigated, by conducting surveys. This does not reduce the risk, but makes an unforseen a certainty. The removal of asbestos and UXOs can be managed by including in the programme and a specialist subcontractor brought in to remove these.
There is however a chance that undetected asbestos and UXOs could be found, expecially in non-intrusive site investigations take place, as well as excavations uncovering UXOs therefore a risk allowance should still be included for these. The risk probability can be reduced as the project progresses and this will happen during risk workshops, as the probability of finding furhter asbestos and UXOs decrease as the project progresses.

How do you carry out risk analysis and risk management?
- Experienced clients may have access to a risk register from previous schemes that can be used as a starting pint if the project is being undertaken within a wider programme of similar projects.
- A risk management workshop can be organised with the design tram coming together and identifying risk items.
- The risk register can be updated during the meeting and will form the basis of risk management for the project.
- There risks will be continuously monitored as the project progresses.
- Identified risks can either be removed or we can aim to reduce their probability of occurring and put in mitigation measures if they do occur.
