Summary Matrix

Cautionary note: The summary matrix identifies typical risk allocation on an aggregated basis. For each risk allocation, however, there are generally exceptions. For the full discussion on typical risk allocation arrangements, please see the detailed guidance provided in the matrix below.

Purpose of Matrix

This page contains a matrix of risks typically found in a water desalination PPP transaction, together with guidance on how those risks are typically allocated between the Contracting Authority and the Private Partner, the rationale for such risk allocation, mitigation measures and possible government support arrangements. It aims to provide governments (and, additionally, private sector stakeholders) with targeted guidance on the appropriate allocation of project risks in a PPP contract.

Cautionary Note

This matrix contains an indicative - but not exhaustive - list of the main risks typically to be considered in water desalination PPP projects and their typical allocation between the Contracting Authority and the Private Partner. It may be used as a starting point for understanding the risk allocation issues commonly arising in water desalination projects and for developing an individual risk matrix for the project in question. A project’s individual circumstances and its jurisdiction will influence the appropriate contractual risk allocation and there may be additional risks that need to be considered.

See Detailed Risk Identification and Analysis in the Introduction.

Key Risks

  • Environmental and social risk: The Private Partner will bear the risk of obtaining and complying with environmental consents, but there will be an element of shared risk in relation to changes in approach from permitting authorities and external environmental events. Desalination projects are particularly sensitive to external marine environmental events, such as jellyfish or algae blooms, or pollution spills, the risk for which is in principle shared to the extent it goes beyond that which could reasonably have been provided against/ is reasonably capable of mitigation through design. If an impact cannot be mitigated by design (e.g. because it is a necessary consequence of the selection of the project site by the Contracting Authority) then this would in principle be borne by the Contracting Authority. Lenders/other funding institutions involved (such as development finance institutions) are unlikely to allow a project to reach financial close if there are any significant adverse impacts on the environment or the local community. See External environmental events under Environmental risk and Social risk.

  • Power supply: Desalination requires a significant amount of power, and the Contracting Authority is typically responsible for providing the required power (and bearing the risk of any increase in power prices) unless the project is developed as a combined power and water project. In emerging markets or markets where the electricity grid is not sufficiently robust, this places a significant amount of risk on the Contracting Authority. See Operational resources or input risk in Operating risk.

  • Reliance on key membrane supply sub-contract if using reverse osmosis technology: Reverse osmosis (or “RO”) technology requires membranes which need to be replaced on a comparatively regular basis during the life of the project. Membrane supply is comparatively specialised and this can leave the Private Partner/the project exposed should the chosen membrane supplier fail to perform or cease to exist. See Operational resources or input risk in Operating risk.

Type of Project and Scope Considerations

This matrix addresses the common risks for the build, own, finance, operate, maintenance and transfer to the Contracting Authority (at the end of the PPP contract) of a new PPP water desalination project where the potable water is sold to a state-owned single buyer.

Project scope may include associated infrastructure, such as water pipelines and, if necessary, electricity transmission or generation facilities.

Assumptions

The Private Partner finances the development of the new water desalination project and only starts to receive payment from the Contracting Authority (and/or where applicable, users) once the water desalination project is in operation.

Risk in relation to demand for potable water is taken by the Contracting Authority.

Site selection is determined by the Contracting Authority, the potable water produced from the project is sold to the Contracting Authority (generally a state-owned single buyer) and the project will connect to the existing water grid which the Contracting Authority owns (or will own to the extent the Private Partner is required to build infrastructure that is to be transferred to the Contracting Authority once completed).

Market Approaches

The structure outlined in this matrix is a common approach for water desalination projects, although there are other contractual structures and procurement models that Contracting Authorities can use to deliver water desalination infrastructure, such as direct procurement of certain required construction or operational elements of a water desalination project.

The risks and associated guidance included in this matrix will be relevant to different contractual structures and procurement models, but will need to be adapted appropriately taking into account the scope and duration of the relevant contract and financing methods (such as whether there is a need for long term third party lending and how the pricing mechanism works).

Project Revenues, Including Payment Mechanisms

Project revenues are typically generated through the Private Partner receiving (a) availability payments from the Contracting Authority (which will cover the Private Party’s finance costs, fixed operating and maintenance costs and return, and will be paid to the Private Partner to extent the desalination project is available, irrespective of how much it is actually dispatched) and (b) production payments from the Contracting Authority based on the actual quantity of potable water produced and delivered to the Contracting Authority (which are structured to compensate the Private Partner for its variable operating and maintenance costs).

Other Considerations

Technology choice: The two main technologies for desalination are reverse osmosis or distillation (of which the main sub-technologies are multiple stage flash distillation and multiple effect distillation). Technology is usually specified by the Contracting Authority but the choice of technology does impact on the cost and technological risks for the project. For example, although reverse osmosis technology is more energy efficient, it is more susceptible to seawater quality including blooms of algae such as red tide and may be reliant on specific suppliers to provide membranes (which need to be replaced periodically throughout operation).

Combined power and water: Desalination is a power-intensive process and, without a dedicated power source, is dependent on sufficient electricity being provided by the Contracting Authority. To avoid risk associated with this, Contracting Authorities sometimes combine desalination projects with power projects, with the Private Party then responsible for managing the internal load required for the desalination process.

Staged operation commencement: Although a single operation commencement regime is more common, the Contracting Authority may wish to implement a multi-staged operation commencement process enabling the Private Partner to begin to receive payment once significant components of the project are substantially completed (e.g. one of several distillation boilers or significant parts of the reverse osmosis system). This can help increase cash flow during the overall construction process, reduce the Private Partner’s financing costs and incentivise the phasing of construction works in order to ensure critical components are completed on time. On the other hand, staged completion dates may also increase the complexity of the construction programme, limit the Private Partner’s ability to mitigate construction delays and/or have agreed damages attached to them, which can increase the risk to the Private Partner and increase the risk of claims for extensions of time/prolongation costs. This is likely only to be suitable where distinct sections of the water desalination project can become operational in phases and where commencement of operation will not distract from ongoing construction requirements.

Private Sector Risk Mitigation

Allocation of risks to sub-contractors: See Risk Allocation in PPP contracts in the Introduction and Cost increases and Works completion delays under Construction risk. As regards construction, the Private Partner will often enter into a lump sum construction contract with a construction sub-contractor to pass down its obligations under the PPP contract and to manage the risk of cost increases and delays (subject to certain relief to which the sub-contractor will be entitled under the sub-contract). The Private Partner will bear the risk of liability caps agreed under the sub-contract being reached or warranty periods under the sub-contract being shorter than the Private Partner’s defect rectification obligations towards the Contracting Authority.

As regards operation, the Private Partner will similarly typically enter into an agreed price operating sub-contract with an operating sub-contractor to pass down its operating phase obligations to the extent practicable. The operating sub-contractor may not be willing to wrap the risk of membrane supply (due to the specialised nature of this supply) (see Operational resources or input risk under Operating risk), meaning that the Private Partner will likely need to procure these under a separate supply contract (with provision of membranes then being the Private Partner’s risk should the chosen membrane supplier fail to perform or cease to exist). In addition, although there may be agreed damages and/or other incentive regimes under either or both of the operating sub-contract or the membrane supply contract, the comparatively small value of these contracts compared to the value of the Private Partner’s revenue under the PPP contract means that the level of such agreed damages and/or incentive payments that these sub-contractors will agree to bear is unlikely to fully compensate the Private Partner for the full amount of its loss of revenue. The Private Partner may require sub-contractors to provide performance security (e.g. bonds, parent company guarantees and/or letters of credit) against non-performance of the sub-contract by the sub-contractor.

Insurance: See Risk Allocation in PPP contracts in the Introduction.

Effective implementation of social and environmental management plan: See Environmental risk and Social risk.

Additional equity and other funding support: See Market Conditions in the Introduction.

Public Sector Risk Mitigation

Carrying out detailed feasibility and ground surveys: See PPP Project Preparation and Delivery in the Introduction. In addition, studies for water desalination projects should include identification and suitability of site, additional land needs (e.g. laydown), interface with existing and future water desalination projects and/or local water grids (and corresponding impact on the project), and social and environmental impact of both the construction and operation of the water desalination project, in particular in relation to water intake and brine containment/disposal and impacts on marine life. Detailed ground surveys should also be carried out where practicable. Where such information is provided to bidders to rely on in pricing their bids, Contracting Authorities may elect to guarantee accuracy but not necessarily completeness or interpretation - this will depend on project-specific factors including the experience of the bidders and the ability to obtain other relevant information.

Running an efficient and fair procurement process: See PPP Project Preparation and Delivery in the Introduction. Enacting enabling legislation (if required) and complying with domestic procurement laws in relation to the project are primarily the Contracting Authority’s risk and responsibility. As the Private Partner will be affected by the consequences of breach of such legislation, it will carry out due diligence itself on these matters. Interference with the tender process and other issues attributable to the Private Partner will remain a Private Partner risk.

Timely consultation on social and environmental impact: It is key for the Contracting Authority to consider the effect of the project on people, wildlife and habitat and to implement effective management of stakeholder interests and public perception before and (in conjunction with the Private Partner) during the project. See Environmental risk and Social risk.

Having competent advisers: See Detailed Risk Identification and Analysis in the Introduction.

Timely involvement of internal stakeholders and contract management team: See Detailed Risk Identification and Analysis in the Introduction.

Careful assessment and quantification of risk: See Detailed Risk Identification and Analysis in the Introduction.

Taking performance security: The Contracting Authority may seek certain security directly from the Private Partner and its sub-contractors, or their parent companies, in respect of certain contractual (or tender) obligations. This may be in the form of bid bonds during the tender stage and, following the tender stage, completion bonds, performance bonds and guarantees. As an alternative, cash reserving mechanisms could be used during the life of the contract. The Contracting Authority will be able to call on this security in certain circumstances (such as performance failures by the Private Partner), Security has a cost attached which will feed through to pricing. Disproportionate security requirements will negatively affect value for money.

Public Sector Support Measures

The Contracting Authority/government may provide certain financial support to the project, in terms of subsidies or guarantees, although the consequences of such commitments and the potential liabilities for the public sector should be carefully considered, including how such support may dilute the risk/reward distribution under the PPP contract and affect value for money.

Where the Contracting Authority’s own credit is weak or uncertain, additional credit support may be sought by the Private Partner and its lenders in respect of the Contracting Authority’s contractual financial obligations. This may be the case, for example, in projects where the Contracting Authority is not part of central government or it is a local authority. To mitigate this Contracting Authority counterparty risk, a sovereign or central government (e.g. finance ministry) guarantee (or equivalent support) may be needed, though the full implication for the public sector should be carefully assessed, including the potential impact on the government’s contingent liabilities and fiscal sustainability. See Demand risk, Project Revenues, Including Payment Mechanisms above and Strength of Contracting Authority payment covenant under Early termination risk.

Land Availability, Access and Site Risk Land Availability, Access and Site Risk

The risk associated with selecting land suitable for the project; providing it with good title and free of encumbrances; addressing indigenous rights; obtaining necessary planning approvals; providing access to the site; site security; and site and existing asset condition.

Risk Category and Description

PublicSharedPrivate

Provision of required land - general

Public Risk
Shared Risk
Public Risk
Shared Risk

[Public Risk]
The Contracting Authority typically bears the risk of selecting the site and acquiring the required land interests for the project, whether through compulsory acquisition/expropriation or other powers, because it has powers to do so which the Private Partner does not. It is also in the Contracting Authority’s interest because on expiry of the contract the asset will typically revert to public ownership and operation (and/or the contract will be subsequently re-tendered). The Contracting Authority is generally responsible for providing a “clean” accessible site, with no restrictive land title issues.

During the feasibility stage (see PPP Project Preparation and Delivery in the Introduction), the Contracting Authority should undertake detailed assessments as regards ownership of the relevant land and ensure that it has a complete understanding of the risks involved in acquiring the site and those that will affect the construction and operation of the water desalination project. 

[Circumstance Dependent Risk]
In addition, studies for water desalination projects should include suitability of site, additional land needs (e.g. laydown), interface with existing and future water desalination projects and/or local water grids (and corresponding impact on the project), and social and environmental impact of both the construction and operation of the water desalination project, in particular in relation to water intake and brine containment/disposal and impacts on marine life.

Such information should be disclosed to bidders as part of the bidding process. This includes consideration of matters such as rights of way, covenants affecting use or disposal and historic encroachment issues that may encumber the land, as well as how the Contracting Authority is addressing such issues and the extent to which bidders are required to price certain risks. To the extent the Private Partner has relied on information provided and priced any such risks, it will share in those risks provided that the information relied on was accurate. Some Contracting Authorities will guarantee only correctness of data provided, not completeness or interpretation.

Land arrangements will need to extend beyond the central project site as required for water pipelines, electricity cables and other utilities to the extent the existing grids do not already have connection points proximate to the site.  Some responsibility for these may sit with the Private Partner if they are dependent on project design.

If the Contracting Authority needs to use its legislative powers to acquire the site (e.g. through compulsory acquisition/expropriation), this may increase social risk and other opposition to the project (e.g. due to delay caused by court cases). See also Social risk.

Market Comparison Summary

In certain markets, land rights (in particular reliable utilities records, and land charges and third party rights to (access) land) may be less clear than in other markets where established land registries and utility records exist and risks can be mitigated with appropriate due diligence. Where reliable information is not available, this will increase the risk of delay, cost increases and disputes. This makes it more likely that the Contracting Authority will need to bear the associated risk as the Private Partner will not be able to bear them.

The rights of private landowners against compulsory acquisition/expropriation might be stronger in developed markets, so the Contracting Authority may need to allow more time to acquire the land.

In emerging markets, if, as is sometimes the case, the land for the project does not have any title deeds, the Contracting Authority will be required to arrange for a contractual licence to use the land. The Private Partner and their lenders are generally comfortable with these arrangements, although such an interest will not be registrable.

Timing of provision of required land

Public Risk
Public Risk

Acquisition pre-signature: : The Contracting Authority should complete the process of land acquisition before the contract is awarded so that all issues and risks are known and managed. All relevant processes will need to be carried out in a timely manner. The timeframe will depend on the issues affecting the site and the applicable processes. The risk that all necessary processes have been satisfied will be the Contracting Authority’s risk.

Acquisition post-signature: : If the Contracting Authority is not able to provide the land by contract award, it will bear the risk of providing it in accordance with a contractually agreed programme. Failure to obtain the land by a certain date may entitle the Private Partner to terminate the contract (see also MAGA risk). If the risk of non-availability is too great, this may deter some investors and financiers from engaging in or continuing in the bid process.

Market Comparison Summary

In certain markets, land rights (in particular reliable utilities records, and land charges and third party rights to (access) land) may be less clear than in other markets where established land registries and utility records exist and risks can be mitigated with appropriate due diligence. Where reliable information is not available, this will increase the risk of delay, cost increases and disputes.

Provision of temporary additional land

Public Risk
Private Risk
Public Risk
Private Risk

Identification pre-signature: [Circumstance Dependent Risk]
Where temporary additional land needs (e.g. for materials or equipment storage during construction) are identified in the procurement phase and are common to all bidders, then the associated risk is usually treated in the same way as the original land. Usually the Contracting Authority will bear the risk of acquiring/providing such land, unless the need for such land is specific to a bidder (for example, due to its construction methods and equipment) – in which case the risk should be allocated to that bidder and the cost factored into its bid price.

The Contracting Authority may however find it needs to provide assistance in some cases, with the cost being borne by the Private Partner.

Identification post-signature: [Private risk]
Where temporary additional land needs (e.g. for materials or equipment storage during construction) are identified, they should be a Private Partner risk as such need should have been identified and factored into the Private Partner’s bid. The Contracting Authority may however find it needs to provide assistance in some cases, with the cost being borne by the Private Partner.

Heritage / indigenous land rights

Public Risk
Private Risk
Public Risk
Private Risk

[Circumstance Dependent Risk]
Land rights issues involving indigenous groups will be the responsibility of the Contracting Authority. The Private Partner will bear the risk of complying with legislation and contractual obligations imposed on it in this regard.

The Private Partner’s obligations with regard to indigenous rights is well legislated for in some markets. In the absence of legislation, indigenous land rights issues and community engagement can be managed by the Contracting Authority through the adoption of internationally recognised social and environmental standards and practices for the project (e.g. compatible with the Equator Principles). This will be particularly relevant if international financing options are desirable.

See also Social risk.

Market Comparison Summary

This issue is coming under increasing focus from multilateral agencies and other finance parties, as well as   civil society and human rights organisations. For example, the World Bank’s commitment to sustainable development is set out in its Environmental and Social Framework which includes standards that both it and its borrowers must meet in projects it is to finance. Many finance parties (including commercial finance parties) adhere to the Equator Principles, committing to ensure the projects they finance (and advise on) are developed in a manner that is both socially responsible and reflects sound environmental management practices (as described in the Equator Principles).

Examples of specific legislation are native title legislation in Australia and the equivalent First Nations law in Canada. These include a requirement to seek consent from the indigenous parties affected and to enter into indigenous land use agreements.

Resettlement

Suitability of land

Public Risk
Shared Risk
Private Risk
Public Risk, Shared Risk
Private Risk

General: [Shared Risk]
The risk that the land is not suitable may be shared as the Contracting Authority may be able to secure the availability of the site, but the suitability of the site may be dependent on the Private Partner’s design and construction plan. Studies for water desalination projects should include environmental impact of both the construction and operation of the water desalination project, in particular in relation to water intake and brine containment/disposal and impacts on marine life.

 See also Environmental risk and Design risk.

Underground: [Circumstance Dependent Risk]
Risk with regard to stability and suitability of the underground conditions sits with the Contracting Authority if no or unreliable data is available and the risk cannot be transferred (or transferring the risk does not represent value for money). To the extent reliable data is available in the tender phase and can be relied upon by the Private Partner, the risk sits with the Private Partner. See also Site condition under Land availability, access and site risk.

Key planning consents

Public Risk
Private Risk
Public Risk
Private Risk

Pre-signature: [Public Risk]
In most projects, there will be a benefit if planning consent for key permits and other key approvals can be obtained by the Contracting Authority before procurement - these may include key environmental consents, although it is possible that some planning consents may remain to be obtained by the Private Party following signature.

Post-signature: [Circumstance Dependent Risk]
If consents for key permits are not obtained before contract signature and the Contracting Authority wants to sign the contract, it will typically bear the risk of the consents being delayed or not obtained (subject to the Private Partner complying with any reasonable requirements) - this may be treated as a compensation event. Failure by the Contracting Authority to obtain the consents by a certain date is likely to entitle the Private Partner to terminate the contract. Permit risk may be complicated further if there are different levels of authorities involved, and interaction between levels of design and authorisations may impact the timeline. If the risk of non-availability is too great, this may deter some investors and financiers from engaging in or continuing in the bid process. See also MAGA risk, Design risk and Environmental risk.

Market Comparison Summary

In some jurisdictions, it may not be possible to obtain the requisite planning consents until such time as the Private Partner has been identified and/or detailed design is known.

Subsequent planning approvals

Public Risk
Private Risk
Private Risk
Public Risk

Obtaining subsequent detailed planning consent and other approvals will be a Private Partner risk. However, the Contracting Authority will share this risk to the extent the relevant authority does not act properly or within approval process deadlines - this may be treated as a compensation event. See also Environmental risk and MAGA risk.

Access to the site and associated infrastructure

Public Risk
Public Risk

Construction phase: In principle the Contracting Authority will be responsible for ensuring the Private Partner can access the site during construction. This will depend on the nature of the access required.  Failure to provide access may be treated as a compensation event. See also MAGA risk.

Operation phase:  Access to the water grid will be the Contracting Authority's risk during the operations phase. The Private Party will be responsible for delivering potable water to the contractual delivery point (which is likely to be at the site boundary) and its responsibility ceases at that point. If there are issues with the wider water grid meaning that the project's production cannot be transported from the delivery point, the project would continue to be paid availability payments and would just not be required to deliver potable water to the Contracting Authority. See also Project Revenues And Payment Mechanisms.

Market Comparison Summary

Third party rights to (access) land may not be easily identifiable in some jurisdictions, increasing risk of delay, cost increases and disputes. This makes it more likely that the Contracting Authority will need to bear the associated risks.

Site security

Public Risk
Private Risk
Public Risk, Private Risk

Construction phase/operation phase: Risk allocation with respect to site security will depend on the political climate, opposition to the project, nature of the risk and the stage of the project. Parties should aim to have a complete understanding of the risks involved in physically securing the site and those that will affect the construction and operation of the water desalination project.

Ordinarily the Private Partner will be responsible for day to day site security. However, the Contracting Authority may need to use statutory means to properly secure the site for the Private Partner (such as police involvement or eviction) and in some circumstances may be required to provide additional site security / assistance during operations to manage this risk. Failure may be treated as a compensation or MAGA event. See also Force majeure risk, MAGA risk, Social risk and Vandalism under Construction risk and Operating risk.

Market Comparison Summary

For example, where there is public opposition to the water desalination project, there may be protestor action, or there may be issues safeguarding the equipment and installation.

Utilities and installations

Public Risk
Shared Risk
Private Risk
Shared Risk, Private Risk
Public Risk

Costs or delays caused by relocation of /access to utilities: [Private Risk]
To the extent reliable data is available and shared during the tender process, the Private Partner can bear and price the corresponding risk of any costs or delays caused by statutory undertakers and utility providers in carrying out work on existing utilities that cross or impinge upon the project site and need to be diverted or relocated prior to implementation of the project. Costs and delays caused by re-location or diversion of existing utilities for the purposes of the project which are due to the Private Partner’s design or construction plan are usually allocated to the Private Partner. For connections to existing infrastructure (such as the water grid), see Access to the site and associated infrastructure above and Project management and interface with other works/facilities under Construction risk.

[Circumstance Dependent Risk]
The Contracting Authority will bear risk if no reliable information is available. It will also bear risk to the extent data provided by it and relied upon by the Private Partner in its bid proves inaccurate.

Lack of data on existing utilities location can make it difficult for the Private Partner to assess (and price) the cost and time needed for relocation or diversion which can impact on the construction timetable and ultimately on meeting the operation commencement date. If the Private Partner bears this risk, the Contracting Authority may need to share the risk by capping the Private Partner’s liability or by having a cost sharing mechanism.

Where existing utilities will remain in place at or in the vicinity of the site, the Private Party may be required (or wish) to enter into crossing agreements or proximity agreements with the owners of the relevant utilities.  

MARKET COMPARISON SUMMARY

In some markets or challenging locations, there may be little data on location of utilities (water, sewage, oil, gas, optical fibre etc.) and the Private Partner may be unable to accept all or part of this risk.

Costs or delays caused by utility provider: [Circumstance Dependent Risk]
Costs and delays caused by a utility provider could arise in both phases and the risk will be allocated according to the relevant circumstances and market and ownership of the utility. The risk could be shared or allocated to the Contracting Authority.

MARKET COMPARISON SUMMARY

In markets where the utility provider is a private entity, this risk is likely to be treated as a relief event (and the utility company will bear the risk) - this is common in mature markets. In less mature markets, particularly where the utility provider is a state-owned entity, the risk is likely to be allocated to the Contracting Authority as a compensation or MAGA event.

Site condition

Public Risk
Shared Risk
Private Risk
Public Risk, Shared Risk, Private Risk

Surveyed: [Circumstance Dependent Risk]
The Contracting Authority usually undertakes detailed geotechnical and ground/soil surveys during the feasibility stage (if not already publicly available) and discloses such information as part of the bidding process. Sharing the surveys will save bidders’ costs (all which would otherwise feed through to the Contacting Authority in the contract price). To the extent reliable data is available and shared during the tender process, the Private Partner can bear and price the corresponding risk of such conditions causing cost and delay.

The Contracting Authority will bear risk to the extent data provided by it and relied upon by the Private Partner in its bid proves inaccurate. Some Contracting Authorities will guarantee only accuracy, not completeness or interpretation of the data.

MARKET COMPARISON SUMMARY

In a mature market, the Contracting Authority normally hands over the site to the Private Partner in an “as-is” condition on the basis of the surveys provided. The Private Partner can rely on the surveys but otherwise bears the risk.

In some markets, the bidders carry out the surveys during the tender process – this may be the best solution in some circumstances, but may also limit competition unless bidders are compensated for these costs.

Unsurveyed: [Circumstance Dependent Risk]
Where it is not possible to fully survey site condition prior to award, the risk for unsurveyable land will be allocated to the Contracting Authority (e.g. as a compensation event). The risk may be shared by the Private Partner (e.g. as a relief event) in some circumstances, for example where the risks were within the knowledge of the Private Partner when it priced its bid or an experienced contractor would have considered their existence as being possible. As water desalination projects are likely to be located in industrial/sparsely populated areas, this risk should be unlikely to arise.

Cultural / Archaeological finds: [Circumstance Dependent Risk]
Discovery of artefacts can cause delays and costs as there may be legal or other requirements in relation to reporting them and permitting archaeological study. The risk allocation will depend on the nature of the project, the extent to which the risk was known to and priced by the Private Partner, the reliability of data provided by the Contracting Authority and whether the project location is considered high risk. One approach is to share the risk such that the Private Partner bears the risk in respect of designated areas (such as a low risk area) and the Contracting Authority bears the risk outside such areas (such as a high risk area). Another approach is for the Private Partner to be obliged to coordinate work, but for the Contracting Authority to appoint specialised contractors and to bear cost/delay and interface risk.

MARKET COMPARISON SUMMARY

In markets where reasonable surveys/assessment can be made and the risk priced, discovery of finds is often treated as a relief event.

Unexploded bombs, land mines and other munitions: [Circumstance Dependent Risk]
Discovery of munitions can cause delays and costs as they will need to be defused and removed. The risk allocation will depend on the nature of the project, the extent to which the risk was known to and priced by the Private Partner, the reliability of data provided by the Contracting Authority and whether the project location is considered high risk.

MARKET COMPARISON SUMMARY

In markets where reasonable surveys/assessment can be made and the risk priced, discovery of munitions risk is often treated as a relief event. In some countries, the risk of unexploded land mines can be high and specific surveying and cost provisions may need to be agreed.

Pre-existing environmental pollution: [Circumstance Dependent Risk]
Pre-existing pollution is typically the Contracting Authority’s risk except to the extent it was known to and priced by the Private Partner. Remediation works for certain existing environmental conditions can be expensive so the ultimate risk allocation will depend on the project specifics and the surveys provided to the Private Partner.

Environmental issues caused by existing assets which cannot be adequately catered for or priced (such as intake water contamination) may be retained by the Contracting Authority.

See also Environmental risk and Change in law risk.

Existing asset condition

Public Risk
Private Risk
Private Risk
Public Risk

Where there are existing assets proposed to be used in the project, where practical they should be fully surveyed (and potentially warranted) by the Contracting Authority. To the extent reliable data relating to the condition of existing assets is shared by the Contracting Authority during the tender process and can be relied upon during implementation, the Private Partner can price the risk of using them, including the interface with other aspects of the project and latent defect risks. The Private Partner will then bear the corresponding risk. The Contracting Authority will bear risk to the extent such data proves inaccurate or insufficient, and to the extent of any warranties it provides. Some Contracting Authorities will guarantee only accuracy, not completeness or interpretation.

If latent defects are discovered in assets which are due to be replaced at some point in the life of the contract, the Contracting Authority may be able to mitigate its risk to some extent by having a contractual mechanism which brings forward the replacement date. See also Suitability of design under Design risk, Project management and interface with other works/facilities under Construction risk and Maintenance standards under Operating risk.

The Private Partner will have primary responsibility for managing the environmental and social strategy across the project, however environmental issues caused by existing assets which cannot be adequately catered for or priced (such as intake water contamination) may be retained by the Contracting Authority.
