NEC4 Alliance Contract: the basics


The NEC4 Alliance Contract was published in June 2018. The much-anticipated new standard form contract allows parties to construction projects to more closely collaborate and equally share in that project's risks and rewards.

The Alliance Contract is the last outstanding piece from the fourth edition of the standard form New Engineering Contracts produced by the Institution of Civil Engineers, following the publication of the rest of the NEC4 suite in June 2017. It is effectively a 'design and build' form, intended for the delivery of long-term, complex infrastructure programmes where the volume of work justifies full investment from the client in the processes and fostering the long-term relationships necessary to deliver a successful project.

Contractors on both the demand and supply side are likely to have an interest in understanding this form and how it works. It marks a genuine move away from transactional relationships to long-term collaborative ones at least at tier 1 of the supply chain.

The alliance structure

The Alliance Contract is unusual in that it relies on the establishment of a complex governance regime, similar to what might exist to regulate the relationship between unincorporated joint venture parties. It does not, however, create a 'joint venture' in the way typically encountered between contracting entities.

The main roles in the alliance are:

  • the client – has a number of duties typically associated with an employer. These include selecting the members of the alliance, setting the alliance objectives, initial scope, client's requirements and the performance table. The client's role in appointing the alliance means that it will have to review its selection criteria to ensure that adequate weight is given to those aspects of bids that demonstrate a collaborative aptitude to make alliancing a success;
  • the alliance board – consisting of 'partners', who are individual tier 1 members of the alliance and the client. The alliance board sets the strategy, allocates work, appoints the alliance manager, makes (unanimous) decisions and is the first point of referral for disputes. All alliance board members have an equal voice and voting rights and must act unanimously;
  • the alliance manager – equivalent to the project manager role. The alliance manager manages the alliance in accordance with the contract and implementation plan, and must obey instructions from the alliance board and the client;
  • the alliance delivery team (or 'alliance') – delivers the work of the alliance. This consists of the client and each individual partner, which could be a combination of civil contractors, designers and equipment suppliers (effectively the tier 1 supply chain).

How the alliance model works

The Alliance Contract is a multi-party contract, under which the alliance delivery team all signs up to a single set of terms. The idea is that all parties in the alliance share the risk of the success or failure of the project.

Delivering the project in accordance with the scope remains a central obligation, as it does under all other NEC contracts. The other main responsibilities of the alliance members are:

  • to collaborate with each other to achieve the alliance objectives, as well as the 'partner objectives' of each partner;
  • to work collaboratively to support the delivery of the contract on a 'best for project' basis;
  • to develop and use common systems and processes, as set out in the implementation plan;
  • to give advice, information and opinion fully, openly and objectively to the alliance board, and to other members of the alliance when asked to do so by the alliance board;
  • to establish an integrated alliance delivery team based on a best for project basis and support the sharing of knowledge, information and best practice.

Whilst all NEC contracts require the parties to act in a spirit of mutual trust and co-operation, the wording of the Alliance Contract goes much further by defining the extent of interdependency that the alliance expects of its members. This requires the tier 1 supply chain to adopt a wholly different approach to that which they may be accustomed.

For clients, two critical elements to get right are the alliance objectives and the implementation plan. The alliance objectives are effectively the alliance-wide key performance indicators (KPIs), defined as "an aspect of performance by the alliance ... for which a performance target is stated in the performance table". These could be a wide range of measures that are important for the client and could include, for example, key dates or even the completion date.

The implementation plan combines the governing documents and operating rules of the alliance. These cover the management structure of the alliance, the roles and responsibilities of each alliance member, delegations by the alliance board and, crucially, the common systems and processes that are to be adopted for the operation of the alliance.

The pricing structure of the alliance

The alliance contract form is effectively a reimbursable contract, equivalent to NEC option E, overlaid with a performance regime which consists of targets for meeting alliance objectives set out in a performance table. There are no main options A-F as in the ECC. There are a limited number of secondary option X clauses.

The definition of 'defined cost' simply refers to "the cost of components in the schedule of cost components less disallowed cost", like in the ECC option E. Disallowed cost is simply "cost which is not justified by a partner's accounts and records". This means that, provided that the cost falls into one of the categories of the schedule of cost components and can be substantiated, it will be reimbursed. For any supply chain partner, the content of the schedule of cost components will therefore need to be carefully scrutinised.

Incentivisation under the alliance contract works as follows:

  • at dates stated in the performance table, the alliance manager assesses the alliance's performance in accordance with the performance table. If actual performance exceeds the stated target, then the partners are paid a stated amount for that target. If the target is not met, then the partner pays a stated amount;
  • the 'pain-gain' equivalent works similarly to that in the NEC Option C target cost, although the language is different. At pre-agreed intervals specified in the performance table, the alliance manager assesses the difference between the alliance cost and "the proportion of the budget for the work which has been completed". If the budget is greater than the alliance cost then the partners are paid the amount stated in the performance table. If there is any over-spend, the partners pay that amount. Amounts stated in the performance table are carved out of the liability cap. The critical difference between the alliance contract and other NEC forms is that the calculation of pain-gain takes into account the client's cost as well.

'Client's costs' is a new definition. It is made up of the components of cost incurred by the client as a member of the alliance calculated using the rates and prices contained in the client's cost schedule; plus amounts paid to other people for correcting defects; plus costs and charges identified as payable by the client in the client's cost schedule; less any amount recovered by the client from insurers.

The client's cost schedule is not part of the alliance contract as the schedule of cost components is. Presumably, this will have to be developed by the client with some careful preparation.

Compensation events

One of the main selling points of the Alliance Contract at consultation stage was that it placed limited risk on the supply chain, with most risk being shared in agreed portions. However, there are only eight compensation events, as opposed to 21 under the standard ECC Option E.

The idea behind compensation events is to enable the alliance to be compensated if they occur. They cover circumstances where the client or alliance board do not allow access when stated; changes to scope; suspension by the client; notification of a correction to an assumption which the alliance manager stated about a compensation event; and any others stated in the contract data.

The final compensation event is 'force majeure', which is invariably deleted by employers. However, if it is retained, it is worth focussing on the subtle differences between the alliance force majeure event and that typically contained in ECC Option E. The new wording reinforces the general approach that risks under the alliance contract are carried by the alliance as a whole. For example, to qualify, the event must have been something which the alliance could not prevent, rather than any specific member of it. It must also be such an event that "people or organisations experienced in works similar to the works would have judged at the contract date to have such a small chance of occurring…".

A successful compensation event results in changes to the budget, the completion date and the performance table. Unlike in the ECC, there is no eight-week cut-off for notifying compensation events. The whole procedure is shorter than in the ECC, but there are likely to be discussions around how a procedure which is untested will operate in practice. For example, a compensation event cannot succeed if it "arises from a fault of the alliance". Since some compensation events are likely to result in part from the fault of the client, there needs to be some clarity about what 'the alliance' as a collective body means in this context.

Crucially, weather events and site conditions are not considered compensation events. The alliance contract guidance anticipates that "members of the alliance share the majority of the risk and reward under the contract through the performance measurement process". Such events, where they occur, will continue to incur defined cost plus fee. However, since they are not compensation events their occurrence will not result in the adjustment of the budget, completion date or performance table. Such events could therefore adversely impact pain-gain.

Any time component (usually the critical factor for weather risk) would be treated very differently to how it would be under an ECC. For starters, there is no X7, so no delay damages for failure to achieve completion date. The completion date should be one of the alliance objectives, for which a performance target is stated in the performance table. As the performance table sets out the adjustments to payment if the performance is higher or lower than the target, the partners will be incentivised to manage such risks to minimise their impact on delayed completion of the works.

Risk apportionment

The Alliance Contract adopts a unique approach to risk allocation. It loosely follows the ECC format, with a split into the client's liabilities and the partners' liabilities. Liabilities that do not fall into either category are classed as "other liabilities".

Client's liabilities are limited to four categories:

  • third party claims arising from the client providing a part of the works that are a result of "an intentional act or omission to not comply with the client's obligations stated in these conditions of contract";
  • loss or damage to parts of the works taken over by the client except loss or damage occurring before the issue of the defects certificate which is due to a defect which existed at take over, an event occurring before take over that was not a client's liability, or the activities of the alliance in providing the works on the site after take over;
  • loss or damage to property occupied by the client other than the works, unless it arises from the alliance providing the works;
  • any additional client liabilities set out in the contract data.

Partner's liabilities are third party claims arising from the partner providing the works or resulting from an intentional act or omission not to comply with the conditions of contract. In addition, individual partners are liable for breaches of third party intellectual property rights; death or bodily injury to employees of the partner; and any other liabilities stated in the contract data.

Crucially, certain risks that fall on the client under the ECC are now carried by the alliance as an alliance cost, unless that cost is recoverable through insurance. These include fault in the client's design; loss or damage to plant and materials in the client's possession; and 'specified perils'-type risks such as loss or damage to the works plants and materials caused by war, strikes and radioactive contamination.

What happens if things go wrong?

Successful alliancing depends on all partners pulling their weight. The Alliance Contract therefore includes processes for where a partner is in breach, and allows other members to vote an offending partner out of the alliance. Breach of contract can ultimately lead to termination, as the contract also includes termination for fault provisions.

In keeping with the ethos of shared risk, the contract includes a 'no blame no claim' provision which encourages parties to avoid adopting adversarial positions.

The alliance board should play a significant role in resolving disputes. An independent expert can be called on to give a non-binding opinion, and senior representatives must play an active role (supported by mediation if agreed).

The contract recognises that the statutory right to adjudicate cannot be excluded but, unlike in other NEC forms, does not facilitate adjudication by way of any extended contractual provisions. The expectation is that the Scheme for Construction Contracts would apply.
