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 10845-2 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 documents are required in order to
a) communicate the employer's procedures and requirements in calls for expressions of interest to
respondents who wish to qualify to be invited to submit tender offers or to be admitted to a database,
b) communicate the employer's procedures and requirements relating to the process of offer and
acceptance when tenders are invited, and
c) establish, in the contract between an employer and a contractor, the agreed terms and conditions, the
prices, and the nature and quality of the goods, services or construction works that are required.
A uniform format for the compilation of calls for expressions of interest and tender and contract documents
provides the platform for the standardization of the component documents and improved communications
between those engaged in the procurement process.
