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

Economic Analysis

Nick Lavingia 7

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

Cost Estimating

What is a Cost Estimate?

• Realistic representation of final project cost at any stage of project development to meet a specific project objective

• Basic Components:

Planning / Scheduling

Nick Lavingia 20

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
