Use Less Water

•  Canadians –  Use an average of

390L/day of water –  Are the second-largest

per-capital users of water in the world

•  Buildings –  Use only 3% of clean,

treated water for drinking!

Risk

11 11

Risk Mitigation Strategies Risks in a project are always present. It is identifying them up front and taking proactive measures to mitigate the negative effects on the project that requires a systematic approach to risk management such as:

•  Identify and quantify

•  By making them explicit they are easier to manage

•  Have a plan to deal with each one, control them and thus minimize potential damage

•  Identify risks as part of value management

•  Ensure good Health and Safety Management plans are in effect

•  Maximize and pre-qualify major subtrades for quality, performance and fiscal responsibility

12

Risk

•  Overall Project Risk: – DesignBidBuild/Lumpsum = lower risk – DesignBuild/ConstrMgmt = Higher Risk

•  Compliance Path Risk: – Simple Prescriptive = low risk/flexibility – Simple/Detailed Trade Off = med risk/flexibility – Performance = low risk/med flexibility

The Pre-Design Phase

•  Pre-conception: •  What, Where, When

•  Conception: •  What, Where, When

•  Project Definition: •  What, Where, When

•  Budget: •  Who •  Estimate

•  (Ball Park?, Order of Magnitude?, Unit price?) 14
