Public–Private Partnerships (PPPs) and Delay Claims: A Ticking Time Bomb?

Public–Private Partnerships are often sold as the safe option. They provide:

Balanced risk allocation.
Bankable contracts.
Clear interfaces.
Strong governance.

On paper, PPPs look like the antidote to claims and disputes. But how do they look in reality?

They may be one of the most delay-sensitive project models ever created.

And many stakeholders are sitting on a ticking time bomb without realizing it.

Why PPPs Are Different When It Comes to Delay

In a traditional construction contract, delay usually means one thing: time and money between Employer and Contractor. In a PPP, delay is never just “a construction issue”.

A single delay event can cascade across:

construction milestones
availability payments
financing covenants
debt service schedules
ender step-in rights
termination regimes

Suddenly, a 60-day delay is no longer a scheduling problem.

It becomes a financial and political problem.

The Silent Killer: Revenue-Based Risk

Here’s the uncomfortable truth:

In many PPPs, delay equals lost revenue, not just prolongation cost.

Availability payments start late.

Shadow tolls shift.

Unitary payments are reduced.

Performance deductions bite earlier than expected.

Yet I regularly see:

weak delay entitlement strategies
late or defensive notices
schedules prepared “for progress”, not for claims
risk registers that ignore delay-revenue interaction

That’s how PPP projects sleepwalk into disputes.

Why Delay Claims in PPPs Fail (Even When Delay Is Real)

From a forensic delay perspective, PPP claims fail for three recurring reasons:

1. The baseline programme was never bankable

It satisfied procurement—but not forensic scrutiny.

2. Delay responsibility is blurred by interfaces

Public Authority. SPV. O&M contractor. EPC contractor. Lenders.

Everyone owns a piece of the delay—until no one owns it.

3. Time is analysed in isolation from finance

Yet in PPPs, time is finance.

If your delay analysis cannot explain:

when revenue should have started
how delay affected cash flow
whether mitigation protected lenders

you are already on the back foot.

The Dangerous Illusion of “Risk Transfer”

PPPs love the phrase risk transfer.

But delay risk is rarely transferred cleanly.

Instead, it is:

fragmented across contracts
diluted through interfaces
misunderstood during execution
weaponized during disputes

By the time arbitration or expert determination starts, the delay story has been rewritten five

times—often inconsistently.

That’s not risk transfer.

That’s risk postponement.

What PPP Projects Should Be Doing (But Often Don’t)

From experience, the projects that survive delays without imploding do three things early:

Treat the baseline programme as a legal instrument, not just a planning tool
Link delay analysis directly to payment mechanisms and financing models
Document mitigation decisions in real time, not retrospectively

Delay analysis in PPPs is not about proving who is late.

It’s about proving who carried the economic consequence of time.

Final Thought

PPPs don’t fail because they are complex.

They fail because teams underestimate how fast delay becomes systemic.

If you’re involved in a PPP—public authority, SPV, contractor, lender, or advisor—ask

yourself one question:

If a major delay occurs tomorrow, do we already know who pays, how much, and why?

If the answer isn’t crystal clear, the clock is already ticking.
