The planning and design for N17 Knock to Collooney Project Road commenced in 2018. The project’s development will follow the structure of the 2017 NRA Project Management Guidelines which divides the evolution and progression of a project into 8 phases as illustrated below;

The purpose of Phase 0 is to ensure the project is in alignment with current TII strategic programmes and plans.

1. Processes – Identify Project with a Project Information Sheet.
2. Deliverables – Project Dossier, Cost Management Deliverables and Project Appraisal Deliverables (PAG).

The purpose of Phase 1 is to identify the need for a scheme and to establish a Project Management Structure including the appointment of Service Providers, where necessary. Phase 1 can also include feasibility studies that may be carried out investigating whether a scheme is warranted/necessary.

The purpose of Phase 2 is to identify a suitable Study Area for the examination of alternative routes, to identify key constraints within that Study Area, to develop feasible route options and to carry out a systematic assessment of these options leading to the selection of a Preferred Route Corridor which will form the basis for the detailed design to follow.

The purpose of Phase 3 is to develop the design of a scheme, following the selection of a Preferred Route Corridor, to a stage where sufficient levels of detail exist to establish land-take requirements and to progress the scheme through the statutory processes. The design may be completed to sufficient detail to identify junction types, locations, accommodation works etc. and to assist in the scoping of the environmental assessments required to develop proposals to go forward to the statutory process in Phase 4.

The purpose of Phase 4 is to prepare the relevant environmental assessments/reports/statements necessary to confirm that the proposed scheme is in accordance with planning and environmental legislative and procedural requirements. In tandem with this, the mapping necessary for land acquisition is prepared in accordance with the statutory processes.

The purpose of Phase 5 is to prepare any Advance Works Contracts and to prepare the tender documentation, assessment of tenders and award of the Main Construction Contract.

The purpose of Phase 6 is to administer the Main Construction Contract and manage the entire Scheme during the Construction and Implementation Phase.

The purpose of Phase 7 is to complete all outstanding contractual and residual issues relating to the Scheme leading to the closeout of the entire project and on the review of the Scheme to ascertain the key lessons to be learned for future Schemes.
