THE CURRENT STAGE

GENERAL

The Project is currently at Phase 2 of the TII Project Management Guidelines as outlined in Figure 1.

Figure 1: TII Project Management Guidelines – Project Phases The purpose of Phase 2 is to examine alternative options to determine a Preferred Option.

A key attribute of Phase 2, and indeed Project development, is the facilitation of stakeholder engagement by the Road Authority.

TII PROJECT MANAGEMENT GUIDLINES

FEASIBLE OPTIONS

During this Phase all reasonable / Feasible Options are examined (Option Selection Process) and their costs, benefits and effects on the environment are interrogated to identify a preferred option that will progress to Phase 3 (Design and Environmental Evaluation) Options which have been presented at this stage of the process are broad options which have been established based on expert judgement and opinion; it is important to note that they have not been subjected to rigorous assessment and comparison, this is an ongoing process which will continue into early 2021.

The option design process is iterative and flexible, as the options reduce in number, the design’s and assessment’s will become more focussed, targeting specific areas for improvement. This may include the amalgamation of certain options and in some instances the examination of further design options.

OPTIONS ASSESSMENT

PRELIMINARY
OPTIONS ASSESSMENT

The assessment and appraisal process will consist of 3 Stages (Figure 2). The first stage will include an analysis under the 3 headings of Engineering, Economy and Environment.

These headings are further sub-divided under a wide range of specific disciplines which include: Transport, Safety, Economics, Socio-Economics, Population, Human Health, Air Quality, Climate Change, Noise & Vibration, Biodiversity, Property, Agriculture, Landscape & Visual, Archaeology, Architecture & Cultural Heritage, Hydrology & Hydrogeology, Soils & Geology, etc.

Independent experts have been appointed to each of these roles.

Phase 2: Options Selection

Figure 3: TII Project Appraisal Guidelines
(PAG) Assessment Criteria

PROJECT APPRAISAL

The best option’s arising from the Preliminary Options Assessment, together with any other potential beneficial options which may be established during the process, will progress to a more detailed appraisal conducted under the 6 headings of: Economy, Safety, Accessibility & Social Inclusion, Integration (Policy), Environment, and Physical Activity (Figure 3). These headings will also be subdivided into a range of sub-disciplines similar to those described at Stage 1 above.

PREFERRED OPTIONS(S)

The final stage of the process will relate to the selection of a Preferred Option. More detail will be considered at this stage under the same criteria described for the Stage 2 – ‘Project Appraisal’ Stage.

DESIGN PROCESS

A key aspect of the process will be the iterative and flexible nature of the design/option evolution as outlined in Figure 4.

TIME LINE’S
AND EVOLUTION

A general overview of the Project timelines is provided in Figure 5. In addition to timelines, this figure also provides an analogy with regards to how the project will evolve over time and how uncertainty will be reduced throughout the various different project phases. Figure 6 describes the symbols provided in Figure 5.

STAGE

DESCRIPTION OF CLARITY / DETAIL/ EVOLUTION

FEASIBLE OPTIONS

Start of Preliminary
Options Assessment.

A Long List of Options is developed. These options are considered ‘Feasible’
but have not yet been tested against the ‘Objectives’and the effects on the
‘Environment’. Clarity is Low.

REFINED
FEASIBLE OPTIONS:

Start of Project Appraisal.

The number of options reduce. More time is spent working on the detail and improving options to increase performance and reduce impacts. Clarity increases slightly, but is still relatively Low.

THE EMERGING OPTION

is put on Public Display

One Option is established; however, this is at a broad level. Details will be refined down during the proceeding Phase 3 (Design and Environmental Evaluation) and will further examine modal opportunities, geometry, junctions, road type, access requirements, ancillary infrastructure etc. At this stage a wide 500m corridor will be established. Clarity is high in terms of general geographical location but is still Low in terms of detail.

STATUTORY CONSENT

(Planning/ CPO).

The option is set down in terms of its detail and how it interacts with the existing environment. Clarity and Detail are High.
