Safety is an underlying value!
Safety is the foundation on which we build projects & conduct our business:
Technology selection Facility layout Detailed design / procurement Construction Commissioning & start-up Ongoing operation
We manage safety as a fundamental part of conducting our business

Net Present Value (NPV)… “Show Me The Money”
Definition: • Sum of the Net Cash Flow discounted to time zero using a
discount rate
Benefits: • Incorporates time value of money ; easy to understand;
recognizes magnitude of profit• Can be used for screening and ranking
Disadvantages: • Independent of the size of the cash flows
Profitability Criteria
Nick Lavingia 8
Profitability Criteria
Rate Of Return (ROR)…“Interest Rate”
Definition: • Discount rate which equates the sum of the Net Cash
Flow after tax to zero
Benefits: • Incorporates time value of money • Easy to understand• Easy to compare with the cost of capital
Disadvantages: • Independent of the size of the cash flows• Can be difficult to determine• Assumes reinvestment at same rate
Nick Lavingia 9
Profitability Criteria
Payout… “Time The Money Is Hanging Out There”
Definition:
• Time for Cumulative Net Cash Flow after tax = Investment
Benefits:
• Simple
• Indicator of investment risk
Disadvantages:
• Ignores time value of money
• No indication of what happens after payout
Nick Lavingia 10
Profitability Criteria
Discounted Profitability Index (DPI)…“Bang For The Buck”
Definition: • DPI = 1 + (NPV of Net Cash Flow / NPV of Investment)
Benefits: • Accounts for the relative size of the cash flows• Used for screening / ranking • Recognizes magnitude of profits
Disadvantages:• Does not give as good an indication of sensitivity to additional
investment as NPV

Project Time Management - Scheduling
Project Time Management includes the processes required to ensure timely completion of the project:• Activity Definition - identifying the specific activities that
must be performed to produce the various project deliverables
• Activity Sequencing - identifying and documenting interactivity dependencies
• Activity Duration Estimating - estimating the number of work periods which will be needed
• Schedule Development - analyzing activity sequences, activity duration and resource requirements to create the project schedule
• Schedule Control - controlling changes to the project schedule

Estimates are inaccurate because they are predictions
of future events and the amount of variation that will actually occur is unknown.
Contingency or Float is Added to Estimates to Reduce the Risk of Overrun.

Current Trends in Contracting & Procurement
Materials & Equipment
• Lead times are increasing
• Prices are increasing
• Inventories are decreasing
• Material shortages
Services
• Contractor capacity is decreasing
• Craft workforce shortage
• Labor rates increasing
Fabrication
• Shop loading is high
• Pricing is volatile
Marketplace
• Marketplace is strong
• Global mega projects
• Suppliers have choices
Nick Lavingia 26
What Can Buyers Do?
Demand Planning
• Plan requirements well in advance
• Aggregate demand
• Leverage volume
Market Intelligence
• Use market data to mitigate cost increases
• Monitor supply/demand
• Investigate new market entrants
Supplier Relationships
• Exploit long term relationships
• Qualify additional suppliers
• Don’t let supplier know you are desperate
Commercial Considerations
• Have and stick to Strategy
•Tie cost increases (future decreases) to major underlying cost components
• Leverage volume & spend
• Lengthen term of agreement
• Define work scope & manage contractors

Progress Report No. 3
1. Cost Variance (CV) = Earned Value (EV) – Actual Cost (AC)
CV = 1200 - 2000 = - 800
2. Schedule Variance (SV) = Earned Value (EV) – Planned Value (PV)
SV = 1200 - 1600= - 400
3. Cost Performance Index (CPI) = Earned Value (EV) / Actual Cost (AC)
CPI = 1200 / 2000 = 0.6
4. Schedule Performance Index (SPI) = Earned Value (EV) / Planned Value (PV)
SPI = 1200 / 1600 = 0.75
5. Estimate To Complete (ETC) = [Budget At Completion (BAC) – Earned Value (EV)] / Cost Performance Index (CPI)
ETC = (3000 - 1200) / 0.6 = 3000
6. Estimate At Completion (EAC) = Actual Cost (AC) + Estimate To Complete (ETC)
EAC = 2000 + 3000 = 5000
