ICE’s collaborative NEC contract suite is the infrastructure procurement route of choice in the UK, Hong Kong, South Africa and New Zealand. Ian Heaphy introduces the latest member of the family, the NEC4 Alliance Contract.

Following extensive industry consultation, ICE’s NEC division launched the NEC4 Alliance Contract (ALC) at the NEC Users’ Group annual seminar in London earlier this year.
The contract marks the next stage in NEC’s 25-year history of collaborative construction procurement and creates a ‘true’ alliance arrangement, where the client and all key members of the supply chain are engaged under a single set of conditions of contract.
All members of an ALC alliance have an equal voice and share in the performance of the alliance as a whole, as opposed to their own individual performance.
The contract is designed for use on major projects or programmes of work, where longer-term collaborative ways of working are to be created.
It can also be used to deliver a programme where a number of lower-value projects can be combined to create a major programme of work.
Further collaboration can be achieved using secondary option X12 multi-party collaboration, which incentivises multiple suppliers to collaborate to achieve a common set of objectives set by the promotor (commonly the client).
ALC takes this further, building option X12 into the core of the contract.
Members of the alliance are thus required to collaborate with each other to achieve alliance objectives and individual member objectives. They work collectively to support delivery of the contract and establish an integrated alliance delivery team on a best-for-project basis.
An alliance board has overall responsibility for the alliance and sets strategy, appoints an alliance manager, makes decisions and resolves disputes.
Each alliance member has an alliance board representative, including the client.
The alliance manager manages the contract on behalf of the alliance and undertakes many of the functions exercised by the project manager or service manager under other NEC contracts, as well as some aspects of the contractor’s role.
Reflecting the collaborative nature of the contract, the majority of decisions of the alliance have to be made unanimously by the alliance board.
Alliance members share the majority of risk under the contract and agree that there can be no claims made against other members of the alliance except for very limited exceptions, principally due to a deliberate breach of contact.
All partners are incentivised to achieve alliance objectives through a performance table, which sets out what performance is required and the reward or deduction regimes that apply if the performance targets are over- or under-achieved.
There’s already been considerable interest in the ALC from NEC users. The new contract also supports ICE’s Project 13 initiative to shift infrastructure procurement from transactions to enterprises.

NEC approach to alliancing
All contracts in the NEC4 contract suite, which was launched in 2017, and their predecessors are collaborative in nature. They allow all key members of the supply chain to be engaged under contracts that contain the requirement at clause 10.2 for the parties to, "act in a spirit of mutual trust and co-operation".Further collaboration can be achieved using secondary option X12 multi-party collaboration, which incentivises multiple suppliers to collaborate to achieve a common set of objectives set by the promotor (commonly the client).
ALC takes this further, building option X12 into the core of the contract.
Members of the alliance are thus required to collaborate with each other to achieve alliance objectives and individual member objectives. They work collectively to support delivery of the contract and establish an integrated alliance delivery team on a best-for-project basis.
Structure of the alliance
The client has a dual role in the ALC in that it has certain retained powers and functions that it performs outside of the alliance, as well as the power and functions of an alliance member.An alliance board has overall responsibility for the alliance and sets strategy, appoints an alliance manager, makes decisions and resolves disputes.
Each alliance member has an alliance board representative, including the client.
The alliance manager manages the contract on behalf of the alliance and undertakes many of the functions exercised by the project manager or service manager under other NEC contracts, as well as some aspects of the contractor’s role.
Reflecting the collaborative nature of the contract, the majority of decisions of the alliance have to be made unanimously by the alliance board.
Alliance members share the majority of risk under the contract and agree that there can be no claims made against other members of the alliance except for very limited exceptions, principally due to a deliberate breach of contact.
Performance table
Payment by the client to other alliance members, which are referred to as partners, is on the basis of defined cost.All partners are incentivised to achieve alliance objectives through a performance table, which sets out what performance is required and the reward or deduction regimes that apply if the performance targets are over- or under-achieved.
There’s already been considerable interest in the ALC from NEC users. The new contract also supports ICE’s Project 13 initiative to shift infrastructure procurement from transactions to enterprises.
