(1) A procurement entity may select consultants by quality-based selection for the following types of assignments:

(a) complex or highly specialised assignments, where

(i) it is difficult to define precise terms of reference and the required input from the consultants;

(ii) the client expects the consultants to demonstrate innovation in their proposals;

(b) assignments that have a high downstream impact where the objective is to have the best experts; and

(c) assignments that can be carried out in substantially different ways where proposals will not be comparable.

(2) A procurement entity may use selection under a fixed budget approved by the Board where the assignment is simple and can be precisely defined.

(3) A procurement entity may use least-cost selection procedures for small value assignments subject to the value threshold in Schedule 3 where the assignment is of a standard or routine nature and well-established practices and standards exist.

(4) A procurement entity may use selection based on consultants' qualifications for very small value assignments subject to the value threshold in Schedule 3 where the need to prepare and evaluate competitive proposals is not justified.

(5) The procurement entity may select consultants by inviting proposals from a single consultant where there is

(a) only one eligible consultant;

(b) an emergency as specified in section 40(1)(b) and (c); or

(c) a follow-up assignment.
