The Alliance contract is a multi-party contract, which does not allow parties to take legal action against each other, thereby eliminating claims, outside of highly defined occurrences of willful default. It is a true collaborative contract. The Alliance model utilizes a joint governance and management structure between owners and private sector parties. The contract aligns the interest of the parties through pain-share/gain-share provisions, which share risk and reward among the parties of the alliance. If the actual cost of the project exceeds the target cost, the extra costs are shared between the public sector and private sector participants on a 50/50 basis until the overhead and profit of the private sector participants reach zero. After this point, all extra costs are borne 100 percent by the public sector. The same principle applies to situations where the project’s actual cost is less than the target cost, where the public and private sector share savings on a 50/50 basis. The only difference between the pain-share and gain-share is there is no cap on the gain-share.
In addition to the pain-share/gain-share provisions around cost, there is normally a pain-share/gain-share mechanism around key performance indicators that are directly related to the owner’s project objectives (e.g., schedule, apprentices trained, sustainability targets, stakeholder engagement).
The Alliance model is typically associated with complex infrastructure projects where the project scope is difficult to define fully, risks cannot be adequately defined or measured, or the cost of transferring risk to the contractor is too high. Additionally, this model may be chosen for projects with tight timeframes, where the owner is able to provide value through involvement in the delivery and implementation of the project or in the case of challenging stakeholder issues that need to be managed.
There are two different procurement approaches regarding Alliance, Single Target Outturn Cost (TOC) and Competitive Alliance (aka dual TOC). Both are described below.
