Abstract
In large EPC and turnkey projects, delays are often treated as operational problems to be solved through acceleration, coordination, and resource deployment. However, in disputes governed by modern EPC contracts—particularly FIDIC Silver Book—the real battle is rarely about fixing delays. It is about who controls the legal narrative of causation. This paper examines how design delays, especially IFC (Issued For Construction) information failures, can evolve into high-risk legal situations, and how contractors must distinguish between factual responsibility and contractual causation in order to protect their commercial and legal position.
The Illusion of Technical Problems
Most engineers and project managers instinctively view delays as technical failures:
- Drawings were late
- Shop drawings were not submitted
- Fabrication was delayed
- Erection sequencing collapsed
These are treated as problems of:
- Planning
- Coordination
- Competence
- Resourcing
But in EPC contracts, especially lump-sum turnkey forms, these are not the real issues.
The real issue is always:
Who will be legally held responsible for the consequences of these failures?
Because responsibility determines:
- Liquidated damages
- Termination risk
- Loss of EOT
- Arbitration exposure
In other words, delays are not engineering events.
They are liability allocation events.
Two Realities: Factual vs Legal
Every major project operates under two parallel realities:
a) Factual Reality
What actually happened:
- Which party missed deadlines
- Which department failed
- Which consultant delayed
- Which drawing was not issued
This is the reality engineers live in.
b) Legal Reality
What can be proven under the contract:
- Who controlled the process
- Who owned the risk
- Who prevented performance
- Who created impossibility
This is the reality tribunals decide cases in.
The dangerous mistake is assuming these two realities are the same.
They are often completely different.
The Brutality of EPC Risk Allocation
Under traditional construction contracts, employers retain substantial design risk. Under EPC / turnkey contracts—particularly FIDIC Silver Book—this is reversed:
- The contractor carries most risk.
- Design responsibility is pushed downstream.
- Internal failures are irrelevant externally.
From the employer’s perspective:
“You are one contractor. Your internal structure does not matter.”
This creates a structural problem:
Even when delays are clearly caused by:
- Design consultants
- JV partners
- Specialist engineers
The employer still legally sees:
One entity. One liability.
This is why EPC contracts are not “fair” contracts.
They are risk concentration instruments.
The Prevention Principle (The Only Real Defence)
The single most important doctrine in EPC delay disputes is the Prevention Principle:
A party cannot insist on performance of an obligation which it has itself prevented.
This sounds simple, but its implications are profound.
It shifts the question from:
“Who failed?”
to:
“Who controlled the conditions necessary for performance?”
In practice, tribunals ask:
- Was the contractor willing and able to perform?
- Was performance made impossible by external constraints?
- Who controlled those constraints under the contract?
This is not about blame.
It is about control of the contractual system.
Why Design Information Is Legally Explosive
Design information (IFC, AFC, approved drawings) occupies a unique legal position because:
- It is essential for performance.
- It cannot be substituted easily.
- It is governed by formal approval processes.
- It is often controlled by the employer’s representative.
Even if the contractor or its partners prepare the drawings, they are not legally usable until:
- Approved by PMC
- Accepted by employer
- Released as IFC
This creates what lawyers call:
Employer-controlled information flow
Which means:
Even contractor-generated drawings may legally belong to the employer’s risk domain.
The Most Common Strategic Mistake
The most common mistake contractors make is saying:
“Our partner delayed.”
“Our designer failed.”
“We had internal problems.”
These statements feel honest.
They are also legally catastrophic.
Because once you admit internal failure, you destroy:
- The prevention argument
- The impossibility defence
- The EOT pathway
- The causation link
And you replace it with:
Self-inflicted default.
Narrative Control: The Real Battlefield
In every EPC dispute, there are only two competing stories:
Employer’s Narrative:
“The contractor failed to perform.”
Contractor’s Narrative:
“The contractor was prevented from performing.”
Everything else—letters, meetings, schedules, logs—exists only to support one of these two stories.
Whoever controls this narrative usually controls:
- Arbitration outcome
- Financial exposure
- Termination justification
- Damages recovery
This is why correspondence is more important than meetings.
And wording is more important than intentions.
Why Silence and Politeness Are Dangerous
Many engineers avoid confrontation and prefer “working it out”.
Legally, this is fatal.
Silence is interpreted as:
- Acceptance
- Waiver
- Admission
Polite cooperation without reservation is interpreted as:
- Voluntary risk assumption
- Waiver of entitlement
- Acceptance of default
In law:
Good behaviour does not protect you.
Only documented position does.
The Separation of Internal and External Reality
Professionally mature contractors learn to operate in two parallel modes:
Internally:
- Identify real causes
- Fix real problems
- Hold real parties accountable
Externally:
- Frame everything as process failure
- Focus on contractual systems
- Avoid personal attribution
This is not dishonesty.
It is legal causation analysis.
Tribunals do not care who made mistakes.
They care who controlled the system that made compliance impossible.
Why Engineers Lose Arbitrations
Engineers lose disputes because they:
- Speak in technical language
- Admit operational problems
- Focus on fixing instead of framing
- Underestimate the power of records
Lawyers win disputes because they:
- Control causation narratives
- Separate fact from liability
- Use prevention logic
- Treat letters as future evidence
The difference is not intelligence.
It is mental model.
The Fundamental Lesson
This entire subject reduces to one uncomfortable truth:
In EPC contracts, disputes are not about what happened.
They are about what can be legally attributed.
And legal attribution depends on:
- Control
- Process
- Documentation
- Narrative consistency
Not effort, sincerity, or competence.
Conclusion
Design delays are not merely project problems.
They are latent legal weapons.
Every delayed drawing, every missing approval, every unclear interface is a potential liability trigger.
The difference between:
- A recoverable claim
and - A terminal default
is rarely engineering.
It is whether the contractor understood that:
The real project is not the plant.
The real project is the contract.
Those who master this distinction stop reacting to delays.
They start architecting legal reality.
And in EPC contracting, that is the only form of control that ultimately matters.
