Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 10845-4 was prepared by Technical Committee ISO/TC 59, Buildings and civil engineering works.
ISO 10845 consists of the following parts, under the general title Construction procurement:
⎯ Part 1: Processes, methods and procedures
⎯ Part 2: Formatting and compilation of procurement documentation
⎯ Part 3: Standard conditions of tender
⎯ Part 4: Standard conditions for the calling for expressions of interest
⎯ Part 5: Participation of targeted enterprises in contracts
⎯ Part 6: Participation of targeted partners in joint ventures in contracts
⎯ Part 7: Participation of local enterprises and labour in contracts
⎯ Part 8: Participation of targeted labour in contracts

Introduction
Procurement is the process which creates, manages and fulfils contracts. Procurement can, as such, be
described as a succession of logically related actions occurring or performed in a definite manner and which
culminate in the completion of a major deliverable or the attainment of a milestone. Processes, in turn, are
underpinned by methods (i.e. a documented, systematically-ordered collection of rules or approaches) and
procedures (i.e. the formal steps to be taken in the performance of a specific task), which are informed and
shaped by the policy of an organization. Methods and procedures can likewise be documented and linked to
processes.
Expressions of interest request potential tenderers to register their interest in undertaking a specific contract
or to participate in a project or programme and to submit their credentials so that they can be invited to submit
a tender offer should they qualify or be selected to do so. Conditions for the calling for expressions of interest
are required to establish procedures from the time that expressions of interest are called for to the time that
respondents are invited to submit tender offers or are admitted to a database. Such conditions document the
procedures, the manner in which those engaged in these processes are to behave, the obligations of the
respondent, and the undertakings of the employer.

INTERNATIONAL STANDARD ISO 10845-4:2011(E)

Construction procurement —
Part 4:
Standard conditions for the calling for expressions of interest
1 Scope
This part of ISO 10845 sets out standard conditions for the calling for expressions of interest which
a) bind the employer and respondent to behave in a particular manner,
b) establish what is required for a respondent to submit a compliant submission,
c) make known to respondents the evaluation criteria, and
d) establish the manner in which the employer conducts the process of calling for expressions of interest.
This part of ISO 10845 is intended for use in procurements relating to goods, services and construction works
and certain disposals other than by auction.
NOTE 1 Annex A contains commentary on the clauses in this part of ISO 10845. Annex B provides guidance on how to
develop the submission data for a call for expressions of interest using this part of ISO 10845.
NOTE 2 ISO 10845-2 establishes the manner in which calls for expressions of interest should be formatted and
compiled. The standard conditions contained in this part of ISO 10845 can, by reference, be incorporated in procurement
documents formatted and compiled in accordance with the provisions of ISO 10845-2.
