The IIAF Gateway Review process provides for a series of short, focused, independent expert reviews, held at key decision points in a project's lifecycle (as depicted in Figure 3). The Gateway Reviews are appraisals of infrastructure projects, that highlight risks and issues, which if not addressed may threaten successful delivery.
The Gateway Review process is in place to strengthen governance and assurance practices and to assist delivery agencies to successfully deliver major projects and programs. Gateway Reviews are part of an assurance process which provides confidence to Government in the information supporting their investment decisions; the strategic options under consideration; and the delivery agency's capability and capacity to manage and deliver the project.
Gateway Reviews are supported by periodic Health Checks which assist in identifying issues which may emerge between decision points. Health Checks will be carried out, when required, by an independent team of experienced practitioners (industry experts including from the private sector), appointed by Infrastructure NSW.
The risk-based application of Gateway Reviews and Health Checks by Infrastructure NSW are depicted in Table 5 and Table 6.
Delivery agencies can nominate additional Gateway Reviews and Health Checks beyond those mandated by the IIAF.

27 Deep Dive Reviews are similar to a Health Check but focus on a particular issue or limited terms of reference rather than the full range of issues normally considered at a Health Check
28 Health Checks for Tier 1 - High Profile/High Risk projects are manadotry during delivery phase if this phase exceeds 6 months.
29 Health Checks may be called for Post Commissioning in an instance where Commissioning of a project/program is undertaken over a longer than usual time duration.
