Getting EPC risk allocation wrong is one of the fastest ways to stall a Vietnamese PPP infrastructure financing. Lenders will not close on a fixed-price turnkey EPC contract that leaves design risk, completion risk, or change-in-law exposure sitting in the wrong place, and project companies caught between an unbankable contractor position and an impatient government counterparty often discover the problem only at financial close — when it is most expensive to fix.
This article sets out how FIDIC Silver Book conventions are actually used (and adapted) in Vietnamese PPP transactions, where lenders insist on step-in rights, how liquidated damages caps are negotiated without destroying bankability, and how interface risk across a multi-contract structure gets allocated between the EPC contractor, the project company, and the State.
What EPC Risk Allocation Means in a Vietnamese PPP Project
EPC risk allocation is the contractual exercise of deciding which party — the EPC contractor, the project company (as owner/borrower), or, indirectly, the government as grantor — bears the financial consequence of a defined category of project risk: design error, construction delay, cost overrun, latent ground conditions, force majeure, or a change in the regulatory regime. In a standalone commercial construction contract, this is primarily a two-party negotiation.
In a Vietnamese PPP infrastructure project, it is a three-way (and often four- or five-way, once an operator and offtaker are added) problem, because the lenders financing the project company sit behind the EPC contract as the ultimate credit support for their debt.
Under Vietnam’s Law on Public-Private Partnership Investment 2020 (Law No. 64/2020/QH14) and its implementing decrees, the project company signs a PPP contract with the competent state authority and then subcontracts construction through a separate EPC contract.
That structural separation is precisely why allocating risk between these contracts has become a specialised discipline in its own right: the PPP contract and the EPC contract must be read together, clause by clause, to confirm that no risk — change in law, site handover delay, force majeure — falls into a gap between the two instruments.
Why Misallocated Risk Kills Bankability
A lender’s credit committee does not ask whether a risk exists; it asks who pays for it if it materialises, and whether that party can actually afford to pay. A project company with no balance sheet beyond the project itself cannot absorb an unallocated risk, so any risk-allocation gap in the EPC contract effectively shifts that risk back onto the lender — which is precisely what project finance is structured to avoid.
This is the single biggest reason the risk-allocation review takes longer in Vietnamese PPP deals than in conventional construction financings.
The FIDIC Silver Book Framework for Turnkey EPC Contracts
The FIDIC Conditions of Contract for EPC/Turnkey Projects (the Silver Book), first published in 1999 and updated in the 2017 second edition, is the template most frequently referenced — directly or as a drafting baseline — in Vietnamese PPP and limited-recourse project financings. It was designed specifically for privately financed infrastructure where the owner wants maximum price and time certainty and is prepared to pay the contractor a premium for taking on that certainty.
Why Lenders Favour Silver Book Conventions
Under the Silver Book, the contractor takes on nearly all design responsibility, site data verification, and the risk of unforeseeable physical conditions, in exchange for a fixed lump-sum price and a fixed completion date.
Lenders favour this allocation because it converts a wide range of construction-phase uncertainties into a single, quantifiable counterparty risk — the EPC contractor’s performance — which can then be supported by performance bonds, parent company guarantees, and insurance, all of which a lender can underwrite far more easily than diffuse project risk.
Adapting Silver Book Drafting to Vietnamese Law
FIDIC’s standard conditions are a drafting baseline, not a plug-and-play instrument under Vietnamese law. Provisions on governing law, dispute resolution (commercial arbitration is generally preferred to Vietnamese courts for cross-border EPC disputes), currency of payment, and statutory retention/warranty periods under the Law on Construction 2014 (as amended) must be reconciled with the Silver Book’s default drafting before the contract is bankable in a Vietnamese PPP context.
Fixed-Price Turnkey Structures and Their Risk Implications
A fixed-price, fixed-date EPC contract is the backbone of nearly every bankable Vietnamese PPP infrastructure financing, because it removes construction-cost and schedule variability from the lenders’ credit analysis almost entirely — provided the contractor can actually perform at the agreed price.
Design Responsibility and the Contractor’s Warranty
Under a true turnkey structure, the contractor warrants that the completed works will be fit for the purpose defined in the employer’s requirements, not merely that the works comply with a specification the employer itself drafted. This single shift — from an input-based obligation to a fitness-for-purpose outcome obligation — is what makes the Silver Book’s risk split meaningfully different from a traditional Red Book design-bid-build arrangement.
Price Certainty Versus the Contractor’s Risk Premium
Fixed-price certainty is never free. Contractors price a risk premium into the lump sum to cover design risk, ground-condition risk, and currency and inflation exposure over a multi-year construction programme. Sponsors negotiating this allocation need to weigh that premium against the alternative cost of carrying residual risk on the project company’s own balance sheet, which is usually far more expensive once financing-cost consequences are included.

Lender Step-In Rights and Bankability Requirements
Lenders financing a Vietnamese PPP project will not accept an EPC contract they cannot step into if the project company defaults under the financing documents. Step-in rights are therefore a non-negotiable bankability requirement, not a negotiating preference, and their absence is one of the fastest ways an otherwise well-drafted EPC contract fails due diligence.
Direct Agreements and Step-In Mechanics
Lenders typically require a tripartite direct agreement between the lenders, the project company, and the EPC contractor, under which the contractor acknowledges the lenders’ security over the EPC contract and agrees that the lenders (or their nominee) may step into the project company’s position following a payment or performance default, without the contractor being entitled to terminate for that default alone during an agreed cure period.
Cure Periods and Bankability Triggers
The length and structure of cure periods — how long the contractor must wait before it can terminate, and what notice obligations it owes the lenders before doing so — is frequently the most heavily negotiated clause in the entire bankability package. Contractors want short, certain cure periods; lenders want enough time to assess the default and decide whether to exercise step-in rights before the contract is lost.
Core Bankability Requirements Lenders Expect
Beyond step-in rights, lenders typically require: an assignable performance security (on-demand bond or parent guarantee); insurance proceeds payable to a controlled account; no unilateral contractor termination rights inconsistent with the direct agreement; and EPC completion tests aligned with the conditions precedent to term conversion under the financing documents.
Liquidated Damages Caps: Balancing Protection and Bankability
Liquidated damages are the project company’s (and, indirectly, the lenders’) primary remedy for late completion or underperformance, but an uncapped LD regime is rarely commercially achievable, and an undercapped one is rarely bankable — so the cap itself becomes a central point of EPC risk allocation.
Delay LDs and Performance LDs Serve Different Functions
Delay LDs compensate for late completion and are usually set at a daily or weekly rate calibrated against the project company’s financing costs and lost revenue during the delay period. Performance LDs compensate for a shortfall against guaranteed output or efficiency parameters at completion testing, and are typically calculated against the capitalised value of the shortfall over the project’s revenue life, not merely the construction cost.
Caps, Carve-Outs, and Exceptions to the Liquidated Damages Cap
Market practice in Vietnamese PPP infrastructure deals typically caps aggregate delay LDs in the range of 10–20% of the contract price, with a separate, often higher, sub-cap for performance LDs, and an overall liability cap — frequently 100% of the contract price — above which the contractor’s exposure is limited for most breach categories, but carved out entirely for fraud, wilful default, and certain indemnities such as IP infringement or death and personal injury.
Force Majeure and Change-in-Law Risk Allocation
Force majeure and change-in-law clauses decide who bears the cost when an event outside any party’s control disrupts the project, and in a Vietnamese PPP structure, this risk allocation question runs across three contracts at once: the PPP contract, the EPC contract, and (where relevant) the offtake or concession agreement.
Allocating Force Majeure Between Contractor and Project Company
Under Silver Book-based drafting, the contractor typically bears the schedule and cost consequences of force majeure events within its control or reasonably insurable, while “political force majeure” events — war, expropriation, or government-imposed restrictions — are usually passed through to the project company, which in turn looks to the PPP contract and the government guarantee or support framework to recover that cost.
Change in Law and Relief Events Specific to Vietnam
Because Vietnam’s regulatory and tax framework continues to evolve, change-in-law clauses in Vietnamese PPP financings are drafted with particular care to distinguish a general, non-discriminatory change in law (ordinarily a project company risk, passed through commercially where possible) from a discriminatory change targeted at the specific project or sector, which is typically allocated to the government under the PPP contract’s compensation or tariff-adjustment mechanism.
Interface Risk in Multi-Contract PPP Structures
Few Vietnamese PPP infrastructure projects are built under a single EPC contract covering every scope item; most involve a primary EPC contract plus separate contracts for specialised works, equipment supply, or utility connections, each with its own interface risk.
Wrap-Around Contracts and Interface Agreements
Where a project company splits scope across multiple contractors, lenders generally require a “wrap” structure — either a single EPC contractor assuming overall interface responsibility for all other package contractors, or a dedicated interface agreement allocating responsibility for coordination failures, scheduling clashes, and defects that cannot be traced to a single package.
Managing the Gap Between the EPC Contract and the O&M Contract
A second, frequently underestimated interface sits between the EPC contract and the long-term operation and maintenance contract: defects discovered after the EPC defects notification period expires but attributable to construction (not operational) causes can fall into a contractual gap unless the O&M contract and the EPC contract’s warranty and indemnity provisions are drafted back-to-back.
FIDIC Silver Book vs Red Book: A Comparative View of Risk Allocation
The table below summarises how the two most commonly referenced FIDIC forms allocate the risks most relevant to Vietnamese PPP infrastructure financings.
| Risk Category | FIDIC Silver Book (EPC/Turnkey) | FIDIC Red Book (Construct) |
|---|---|---|
| Design responsibility | Contractor, fitness-for-purpose standard | Employer/engineer, contractor builds to spec |
| Site/ground conditions | Contractor, limited exceptions | Employer bears unforeseeable physical conditions |
| Price basis | Fixed lump sum, limited adjustment | Measured/re-measurable, more adjustment grounds |
| Completion certainty | High — preferred by lenders | Lower — more contractor claims exposure |
| Typical use in Vietnamese PPP | Primary reference for bankable EPC drafting | Used for simpler, non-limited-recourse works |
Practical EPC Risk Allocation Strategies for Project Sponsors
Sponsors negotiating a Vietnamese PPP infrastructure project can reduce financing delay and renegotiation risk by addressing these risk-allocation issues before the EPC contract is signed, not after term sheet circulation with lenders.
An EPC Risk Allocation Checklist Before Signing
At a minimum, sponsors should confirm: the EPC contract and PPP contract use consistent force majeure and change-in-law definitions; LD caps and the overall liability cap are set at levels the identified lender group has previously accepted in comparable Vietnamese transactions; step-in and direct agreement terms are agreed in principle with the contractor before financial close discussions begin; and interface responsibility for any split-package scope is assigned to a single accountable party.
Early Lender Engagement on Risk Allocation
Because lenders’ bankability requirements are the ultimate test of any EPC risk allocation package, sponsors who circulate a draft EPC contract to prospective lenders before finalising terms with the contractor consistently reach financial close faster than those who negotiate the EPC contract first and the financing second.
Force Majeure Risk Allocation and PPP Infrastructure Vietnam Practice
Lenders in PPP infrastructure Vietnam transactions usually read the force majeure clause first. Clear force majeure risk allocation between the contractor, the project company and the grantor prevents disputes over who funds delay and extra cost.
Sound risk allocation is not about pushing every risk to the contractor. Balanced risk allocation prices each risk with the party best able to control it, and lenders scrutinise that risk allocation closely during due diligence.
Sponsors should document risk allocation decisions in a single matrix mapped to the EPC contract, the concession and the financing documents. A consistent risk allocation matrix helps avoid gaps where no party carries a risk.
When risk allocation changes late in negotiations, sponsors should re-run the base case and re-test lender covenants, since even small shifts in risk allocation can alter debt sizing and the required contingency.
Ultimately, disciplined risk allocation is what makes a Vietnamese PPP project financeable, and early engagement with lenders on risk allocation saves time at financial close.
Frequently Asked Questions
What is EPC risk allocation in a PPP project?
It is the contractual division of construction, design, delay, and force majeure risk between the EPC contractor, the project company, and the government, structured so each risk sits with the party best placed to manage or insure it.
Why do lenders prefer the FIDIC Silver Book for Vietnamese PPP projects?
The Silver Book shifts design and site risk to the contractor under a fixed price and date, converting construction uncertainty into a single, insurable counterparty risk that lenders can underwrite more easily.
What is a typical liquidated damages cap in a Vietnamese EPC contract?
Market practice commonly caps delay LDs around 10–20% of the contract price, with a separate performance LD sub-cap and an overall liability cap, often around 100%, subject to standard carve-outs.
Who bears change-in-law risk under a Vietnamese PPP contract?
General, non-discriminatory changes are typically a project company risk; discriminatory changes targeting the specific project are usually allocated to the government through the PPP contract’s compensation mechanism.
Why do lenders require step-in rights over the EPC contract?
Step-in rights let lenders preserve the EPC contract after a project company default, preventing contractor termination from destroying the project’s value before the lenders can appoint a replacement sponsor or operator.
Sponsors, lenders, and contractors preparing an EPC contract for a Vietnamese PPP infrastructure project should commission an independent bankability and risk-allocation review of the draft EPC contract alongside the PPP contract before signing, rather than after lender due diligence begins.
