4Why Do Mega Projects Fail?
- Unrealistic estimates?
- Lack of governance accountability?
- Appraisal optimism?
- Is delusion necessary for projects to proceed?
(re. Flybjerg Mega Projects Risk) - Flawed execution plan?
- Owner role not performed effectively?
- Poor contractor performance?
- Doing what weve always done (and expecting
better results)?
5Estimating Costs Risks
6Reasons
- Size of the project
- Many resources required
- Complexity of projects
- Technological complexity
- Executed by virtual teams
- Project organization structure
- Multiple owners that do not share same culture
7Reasons
- JV of Project contractors and engineering firms
are not aligned - Different cultures
- Need to ensure that their own responsibilities
are executed as well as possible - May be at the expense of the overall project
8Reasons
- Unrealistic Expectations
- The original cost estimate and schedules are for
project sanctioning, not to provide a realistic
goal for the project teams - Poor/incomplete scope definition i.e. inadequate
front end loading - Poor quality/overly optimistic cost estimates
9Reasons
- Contracting strategies
- Not appropriate for the situation
- Project control
- Nobody has single point responsibility except the
client who does not control much of the work - Underestimation/under appreciation of project
complexity - Inadequate plan of execution
10Reasons
- Unrealistic schedule
- Poor project controls
- Poorly defined tasks and division of
responsibility - Lack of knowledgeable leadership in E, P, C,
Start-up of major facilities - Inexperienced/poorly equipped project management
personnel and supervisors
11Reasons
- Shortage of skilled labour and lower than
anticipated labour productivity - High labour turnover
- Changing customer requirements
- Lack of understanding the costs of changes
12Reasons
- Poor communication and follow-up
- Poor site organization leading to excessive time
wastage - Inability to understand, plan, adapt, implement
procedures or systems
13The Feasibility Study
- A very comprehensive document
- Considerable amount of work to scope the project,
select the technologies to be used and present a
business case - Lots of time and effort
- What Owner wanted to do
- How much it would cost
- What the economics of the investment would be and
- What the risks might be
14The Feasibility Study
- No sufficient level of detailed work done to
achieve the level of accuracy and confidence that
the owners decision makers place in it when a
project is approved - To achieve a level of accuracy of the estimate of
10-15, we need a 30 engineering completion - The right 30 - not just any 30
- in particular considerable technical information/
engineering is required from equipment vendors
15The Feasibility Study
- Limited input from Operations
- May be unknown at this time
- Operations input is invaluable when considering
- Plant and equipment layout
- Equipment selection
- Determining the ongoing operations costs and
staffing needs - Laying out the pre-commissioning and
commissioning requirements and costs, start-up
and early production projections.
16The Feasibility Study
- Downplays or overlooks Organizational Performance
- both at the Joint Venture level and at the
Project level - New companies with new and unproven technology in
industry new to partners - Complexity on complexity
- Benchmarking and Risk Analysis services
- External reviews
- Several concerns are usually raised
- Cost and schedule projections are not
aggressively challenged
17The Feasibility Study
- Not challenged aggressiveness of start-up and the
production ramp up curves - Optimism and a lack of meaningful operations
input contributes to false hopes on the part of
the owners - Overlooking potential impact of new technology
and the inefficiencies and problems that could
result from a new joint venture and sometimes new
players
18The Feasibility Study
- How seriously the project team takes the concerns
that are raised in the external reviews and
respond to them? - Not referred to at all
- Acknowledgement of the concerns and with a
comment that they are being addressed and that
mitigating actions will be taken.
19Delays in Engineering
- Early delays in achieving key milestones such as
- Substantial Completion of Engineering
- Freezing Process Flow Diagrams (PFDs)
- PID issued for design
- Delays do not seem to be reflected on final
project completion date - Fast-tracking the fast-track!
20Delays in Engineering
- A number of development steps
- Production of PFDs - show the logic of the
various chemical steps that will be used in the
new facility. - The quantities of each of the process streams
will be shown - Review and approval of owner before the next
development step is released
21Delays in Engineering
- Develop the Process and Instrument Diagrams
(PIDs) - Identify all the pieces of equipment required for
the process to work - Identify all piping required together with
identification number, size, wall thickness and
metallurgy, valve locations and type as well as
control logic and hook-up - PIDs contain critical engineering detail that
must be agreed upon before the construction
drawings can be started
22Delays in Engineering
- Series of extensive reviews before PIDs are
approved and the detailed discipline engineering
can begin. - PFDs and PIDs Milestones are some of the first
Milestones and it is only once they have been
reached that succeeding activities can be
started. - In fact the Engineering build up can only take
place once these early Milestones have been
achieved - hence their importance.
23Delays in Engineering
- This would put pressure on the completion of the
succeeding activities. - The delay in Engineering can also be caused by
- Additional work by the steady stream of trends
- Either adding to original scope or requiring work
already completed to be re-done - Slower build-up of the engineering workforce than
planned - Lower engineering productivity than expected
- Whatever the reason(s), how do Project Managers
react?
24Trend System
- Changes to the base (AFE) are documented so that
the potential cost and schedule impact can be
flagged and estimated.
25Trend System (cont.)
- When a trend is raised, the originator has to
indicate not only the estimated cost but the
schedule impact of the trend. - Early trends would not change the Mechanical
Completion date - PM can mitigate the delays, by adding people ...
26Trend System (cont.)
- PM should regularly be assessing the cumulative
effects on the overall schedule. - As the number of trends climbs, one thing is
certain - more work and more costs are being
added to the project, and more hours must be
spent before the project is completed. - This means that either the end dates slip or the
additional work identified will take away from
the flexibility that was originally in the
schedule (if any) thus making the probability of
achieving the schedule less likely
27Cost Allowances and Contingencies.
- To cover for design changes, material quantity
increases - Historical and risk based
- The PM should be running down the allowances
and contingencies according to some agreed upon
plan - The huge number of trends raised at the early
stage of a project can provide Warning signal to
the PM that events are not evolving as expected
28GOLDEN RULES FOR AN UNSUCCESSFUL PROJECTS
29- NEVER prepare a realistic cost and schedule
estimate
30Project Estimate
- NEVER provide a good quality cost estimate
- Underestimate/under appreciate project complexity
- Make sure the final completion date is cast in
stone - Be optimistic and any delay during front end or
engineering will be absorbed by construction!
31- NEVER conduct a sufficient Front End Planning
32 Front-end Planning
- NEVER define the scope of work properly
- Highly schedule driven
- Push everything to construction
- NEVER develop alternatives and then select the
best alternative - NEVER make clear what is in scope and what is out
of scope - NEVER consider a proper risk analysis and
management with contingencies for both Tactical
and Strategic risks
33Strategic Risks
- Global Risk Examples
- Broad political uncertainty such as country and
regional instability or changes of government - Product Market issues that affect the spread
between production costs and product price - Project Market issues that affect product and
service availability or pricing for project - Public opposition
- Global and regional economic trends
34Strategic Risks
- Enterprise Risk Examples
- Quality of Project Delivery System- (Governance,
People and Systems) - General business provisions that limit choice or
action - Partners and issues above the project
- Issues with the local government
- Organizational alignment on project goals
- Scope - (Does the project as represented to the
project team identify every element that will
eventually be required?)
35Tactical Project Risks
- Definition (Degree of scope definition in
relation to stage of project) - Contracting strategy effectiveness
- Front End Loading effectiveness
- Issues with compliance with local government laws
/ requirements - Effectiveness of Management of Change
- Materials identification and management
- Logistics risks
- Procurement (pricing) risks
- Engineering Productivity and schedule adherence
- Construction Productivity and schedule adherence
- Site related risks
36Categorize Project Risks to Better Understand Them
Authority / Accountability
Management
- e.g.
- Management intervention in PMT tactics leads to
internally driven risks
- e.g.
- Political
- Global economic trends
- Partner / NOC issues
- Organizational alignment
- e.g.
- Project definition
- Contractor performance
- Pricing
- Logistics
- e.g.
- Unmitigated strategic risks become tactical
problems for PMT

Risk
37- NEVER develop an appropriate contract strategy
38Contract Strategy
- NEVER break the Project to Manageable chunks
- NEVER select the right contractual arrangement
and payment structure - Always adopt fast-track strategy
- With Lump sum combination
- On Mega Oil Sands Projects adopt a cost plus
approach - ALWAYS ASSUME that
- Multiple owners share same culture
- JV of contractors and engineering firms are
aligned and set up to work effectively
39- NEVER apply a proper project control system re
schedule, cost, safety, quality
40Project Control
- NEVER make clear who has single point of
responsibility - NEVER freeze the design
- NEVER worry about early warning signs such as
number of trends, changes, consumption of
contingency and project float - NEVER pay attention to interface management
41- NEVER pay attention to labour productivity
42Construction Productivity
- NEVER consider the following
- Labour relations and morale
- Communications
- Material
- Equipment
- Scaffolding
- Subcontractors
- Supervision and leadership
- Overtime and acceleration
- Workface planning
43- NEVER FAMILIARIZE YOURSELF WITH THE CONTRACT
44ALWAYS ASSUME
- CONTRACT JUST LIKE OTHERS
- MUST BE FAIR and reasonable
45No Damage for Delay
- The contractor shall not have any claim for
compensation for damages against the owner for
any stoppage or delay from any cause whatsoever.
46- NEVER IDENTIFY SCHEDULE EFFECT
47Never document delays and impacts Never request
appropriate extension of time Never make clear
who pays for additional costNever make clear
who pays for acceleration
48- NEVER QUALIFY YOUR CHANGE ORDER PRICE
49ALWAYS ALLOW OWNER TO ASSUME PRICE OF CHANGE
ORDER INCLUDES
- SCHEDULE EFFECT
- IMPACT ON CONTRACT WORK
- CUMULATIVE EFFECT
- PRODUCTIVITY IMPACT
50NEVER WAIT FOR WRITTEN AUTHORIZATION BEFORE
PROCEEDING WITH A CHANGE
51ALWAYS
- ASSUME People are fair and reasonable
- Time is of the essence
- Engineers and contractors focus on getting the
work done!!
52- NEVER MAINTAIN PROPER JOB RECORDS
53PROPER RECORDSMIGHTALLOW YOU TO JUSTIFY
QUANTIFY THE REQUEST FOR ADDITIONAL
COMPENSATIONTHIS SHOULD BE AVOIDED!
54- NEVER READ AND IF NECESSARY OBJECT TO MINUTES OF
MEETINGS
55Thats all and thank you
