The project appraisal, which is carried out in the preparation phase, builds on a set of prioritised
projects, as determined in the identification phase, and results in the defined scope and
standards of a project, which will feed into the design phase, where the project will eventually
be prepared for tendering. The implementation and operation and maintenance phases complete
the cycle. The Code of Procedures provide a description of the various elements of the
preparation phase, aimed towards appraising the projects, as illustrated i This will
apply to the projects which are ranked highest in the prioritisation process.

Feasibility Brief description
Technical Technical feasibility focuses on identifying the technical parameters that will
be addressed in undertaking such projects. Concept designs for roads,
pavements and concepts forms for major structures that will be required are
identified, as well as other major cost items that will be encountered in
implementing the project. Industry norms to determine costs should be
applied.
Environmental
and social
Environmental scoping of potential impacts relating to identified road
projects, including the evaluation of alternatives, needs to be carried out and
social and sustainability issues investigated. Opportunity for initial interaction
