CON 2001 & CVE 4070 Construction Engineering Risk Management Prof. Ralph V. Locurcio, PE
2
Views of risk taking…
3
What is risk??? An outcome different from what you expected or estimated… Or… different from what you bid!
4
Sources of risk in construction… Construction operations are hazardous Labor capacity, capability, competence… Subsurface conditions; physical factors Contractual provisions; timing, LDs… Economic conditions; prices, labor… Political & public; new laws, opposition
5
Basic premise… All risks accrue to the owner unless assigned by contract to another party Assigning risk to another they must be (a)able to assess the risk fairly, (b)competent to do the task, and (c) result in a better solution
6
Risk allocation… at start Owner DesignerBuilder Not yet involved
7
Risk allocation… traditional Owner DesignerBuilder
8
Risk allocation… design-build Owner Designer+ Builder
9
Risk Management Tools Best Value procurements Two stage bid process Contractor helps finalize design Incorporates VE Risk Management Risk identification Analysis Response
10
Pareto Principle 80/20 rule… States that 80% of the value comes from 20% of the activities. Therefore, we need a method to focus on the 20% of the activities that have the most influence on the outcomes. And… we should avoid the 80% of activities that produce little gain
11
Risk identification Identify areas of risk intensity 1.Buildability, logistics, health & safety 2.Environmental, permits 3.Cost environment Develop risk registers 1.Catalog all risk factors 2.Assign responsibility to team members
12
Risk analysis Use decision & simulation theory Quantify maximum effect of each risk Identify probability of occurrence Determine economic impact of each Determine impact of combinations
13
Risk response Plan mitigation strategies Specific action to be taken Avoidance, sharing, protection, etc. Accountable team member Account for inter-relationships Account for multiple risk scenarios
14
Risk Management Strategies Avoidance Transfer or Sharing Mitigation Insurance Recovery
15
Construction Risk Management Avoidance Retention Insurance Education & Training Exemption Clauses Risk sharing Protection Clauses Retention Money Liquidated Damages Rescind contract Contingencies
16
Basic risk management-1… Build a Risk Allocation Matrix Identify all potential risk of loss Assign to Owner, Contractor or Designer Quantify your potential loss Develop a risk management strategy
17
Basic risk management-2 Management strategies… Avoid the potential loss Transfer the risk Share risk with another firm Mitigate the potential for loss Recover any unavoidable loss Claim Insurance Litigation
18
Basic risk management-3 Keys to allocation of risk… Must be a reward for any risk assigned Asignee must be able to control risk Must produce “best” solution Must have financial capability Must follow terms assigned
19
Avoidance… Careful estimating & bidding Study the contract terms Study the owner’s style & record Study limits of insurance Prior planning for construction Examine the plans, specs & conditions Examine the contract requirements Examine the site for unknowns & hazards Examine each process & plan your method
20
Transfer or sharing… Reduce source & size of risk Use the contract terms General conditions Plans & specs Negotiate new terms May not work with government Change strategic approach Merger or joint venture with another firm Hire subcontractor for high risk work Purchase additional insurance
21
Mitigation… Good planning & communication Quality control processes Use/acquire the right skills Use/acquire the right equipment Use your experience wisely Act promptly if the unexpected occurs
22
Insurance… Covers unexpected situations Situations beyond your control Your track record is important Cost is a factor Do not overuse
23
Recovery…if all else fails Read the contract Good record keeping… especially impacts Follow correct procedures Demonstrate mitigation efforts Make a convincing presentation Attempt settlement at lowest level Seek legal help
24
Cost recovery 101 Read the contract Begin mitigation immediately to minimize loss Stay within contractor’s authority Determine risk allocation for each problem Comply with all notification requirements Request contract change when required Establish new activity code for all added work Track cost of new work Quantify delay to other work
