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.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

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. Details of

ISO 10845-4:2021(E)
Introduction

Procurement is the process which creates, manages and fulfils contracts. There are accordingly three

phases to the procurement process associated with the delivery and maintenance of construction

works, namely:

— a planning phase during which decisions are made as to what, where and when goods and services

are required, how the market is to be approached and what is the number, type, nature and timing

of the required contracts;

— an acquisition phase during which contracts are entered into following the execution of a selection

procedure; and

— a contract management (or contract administration) phase during which compliance with

requirements, changes in requirements and risk events which manifest during the execution of

contracts are managed.

Expressions of interest form part of the acquisition phase and are used to 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.

Calls for expressions of interest are associated with the use of the nominated and qualified selection

methods as described in ISO 10845-1 in order to admit respondents to an electronic database or

shortlist of pre-qualified tenderers (or both) so that they can be invited to submit tender offers in

respect of a particular procurement, respectively.

Calls for expressions of interest, when used to pre-qualify or shortlist tenderers, provide the market

with an advance warning of a tendering opportunity and reduce unnecessary abortive costs in

processing and preparing tenders offers. They can also be used to:

a) give the employer time to finalize the procurement documents and eliminate the need for

advertising tenders as only those tenderers who are shortlisted are invited to submit tender offers;

b) ensure that tenders are only invited from tenderers who potentially have the necessary capabilities

and capacities to perform the contract;

c) ensure that a limited number of respondents are invited to submit tender offers (usually not less

than three), where the evaluation of tender submissions is resource intensive or to make the

procurement more attractive to potential tenderers due to the demands made on tenderers during

the tender process in preparing a submission; or

d) allow capability and capacity to deliver the required goods, services and construction works to be

evaluated in two stages or to be omitted in the evaluation of tender offers.

Annex A contains guidance on the application of this document and suggestions on good practice.

Annex B provides guidance on how to develop the submission data for a call for expressions of interest

using this document. Annexes C and D offer guidance on the evaluation of expressions of interest and

the structuring of evaluation reports, respectively.

ISO 10845-2 establishes the manner in which calls for expressions of interest should be formatted

and compiled. The standard conditions contained in this document can, by reference, be readily

incorporated in procurement documents formatted and compiled in accordance with the provisions of

ISO 10845-2.

This document is part of the ISO 10845 series which covers various aspects of procurement within the

construction industry. Each part of the ISO 10845 series relates to a different aspect of procurement.

The objective of the ISO 10845 series is to provide a generic and standard set of processes, procedures

and methods for a procurement system that is fair, equitable, transparent, competitive and cost-

effective and which can be used to promote objectives additional to those associated with the immediate

objective of the procurement itself.

ISO 10845-4:2021(E)
4 General requirements
4.1 Actions

The employer and each respondent submitting an expression of interest shall comply with the standard

conditions for calling for an expression of interest in this document. In their dealings with each other,

they shall discharge their duties and obligations, as set out in Clauses 5 and 6, in a timely manner

and with integrity, behave equitably, honestly and transparently, and not engage in anti-competitive

practices.

The employer and the respondent and all their agents and employees involved in the submission process

shall avoid conflicts of interest and where a conflict of interest is perceived or known, declare any such

conflict of interest, indicating the nature of such conflict. Respondents shall declare any potential

conflict of interest in their submissions. Employees, agents and advisors of the employer shall declare

any conflict of interest to whoever is responsible for overseeing the procurement process at the start of

any deliberations relating to the procurement process or as soon as they become aware of such conflict,

and abstain from any decisions where such conflict exists or recuse themselves from the procurement

process, as appropriate.

The respondent shall not make a submission without having a firm intention and the capacity to

proceed with the next stage of the procurement process.

NOTE 1 A conflict of interest can exist even if there are no improper acts as a result of it. This can arise due to

a conflict of roles which can provide an incentive for improper acts in some circumstances or positions. A conflict

of interest can create an appearance of impropriety that can undermine confidence in the ability of that person to

act properly in said circumstance or position.

NOTE 2 Conflicts of interest with respect to those engaged in the procurement process include direct, indirect

or family interests in the tender or outcome of the procurement process and any personal bias, inclination,

obligation, allegiance or loyalty which can in any way affect any decisions taken.

4.2 Supporting documents

The documents issued by the employer for the purpose of obtaining expressions of interest are listed in

the submission data.
4.3 Interpretation

The submission data and additional requirements contained in the submission schedules that are

included in the returnable documents are deemed to be part of the conditions for the calling for

expressions of interest.
4.4 Communication and employer's agent

Each communication between the employer and a respondent shall be to or from the employer's agent

only, and in a form that can be readily read, copied and recorded, and in the language stated in the

submission data. The employer shall not take any responsibility for non-receipt of communications from

or by a respondent. The name and contact details of the employer's agent are stated in the submission

data.
5 Respondent's obligations
5.1 Eligibility

Submit an expression of interest only if the respondent satisfies the eligibility criteria stated in the

submission data and if the respondent or any of the respondent's principals is not under any restriction

to do business with the employer.
© ISO 2021 – All rights reserved 3
---------------------- Page: 9 ----------------------
ISO 10845-4:2021(E)
5.2 Cost of submissions

and delivery of a submission.
5.3 Checking documents

Check the submission documents on receipt and notify the employer of any discrepancy or omission.

5.4 Acknowledging addenda

Acknowledge receipt of addenda to the submission documents, which the employer may issue, and, if

necessary, apply for an extension to the closing time stated in the submission data, in order to take the

addenda into account.
5.5 Clarification meetings

Attend, where required, clarification meetings, the details of which are stated in the submission data,

at which respondents may familiarize themselves with the proposed work, services or supply (and

location, etc.) and raise questions.
5.6 Seeking clarification

Request clarification of the submission documents, if necessary, by notifying the employer at least five

working days before the closing time stated in the submission data.
5.7 Making a submission

Return all returnable documents and the number of copies of such documents stated in the submission

data to the employer after completing them in their entirety, either electronically (if they were issued in

electronic format) or by writing legibly in non-erasable ink.

Seal the original and each copy of the submission as separate packages, marking the packages

as “ORIGINAL” and “COPY”. Each package shall state, on the outside, the employer's address and

identification details stated in the submission data, as well as the respondent's name and contact

address.

Accept that the employer does not assume any responsibility for the misplacement or premature

opening of the submission if the outer package is not sealed and marked as stated.

5.8 Information and data to be completed

Accept that submissions which do not provide all the data or information requested, completely and in

the form required, may be regarded by the employer as being non-responsive.
5.9 Closing time

Ensure that the employer receives the submissions at the address specified in the submission data

not later than the closing time stated in the submission data. Proof of posting shall not be accepted as

proof of delivery. The employer shall not accept submissions submitted by telegraph, telex, facsimile or

e-mail, unless otherwise stated in the submission data.

Accept that, if the employer extends the closing time stated in the submission data for any reason, the

requirements of the conditions for expressions of interest apply equally to the extended deadline.

ISO 10845-4:2021(E)
Introduction

Procurement is the process which creates, manages and fulfils contracts. There are accordingly three

phases to the procurement process associated with the delivery and maintenance of construction

works, namely:

— a planning phase during which decisions are made as to what, where and when goods and services

are required, how the market is to be approached and what is the number, type, nature and timing

of the required contracts;

— an acquisition phase during which contracts are entered into following the execution of a selection

procedure; and

— a contract management (or contract administration) phase during which compliance with

requirements, changes in requirements and risk events which manifest during the execution of

contracts are managed.

Expressions of interest form part of the acquisition phase and are used to 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.

Calls for expressions of interest are associated with the use of the nominated and qualified selection

methods as described in ISO 10845-1 in order to admit respondents to an electronic database or

shortlist of pre-qualified tenderers (or both) so that they can be invited to submit tender offers in

respect of a particular procurement, respectively.

Calls for expressions of interest, when used to pre-qualify or shortlist tenderers, provide the market

with an advance warning of a tendering opportunity and reduce unnecessary abortive costs in

processing and preparing tenders offers. They can also be used to:

a) give the employer time to finalize the procurement documents and eliminate the need for

advertising tenders as only those tenderers who are shortlisted are invited to submit tender offers;

b) ensure that tenders are only invited from tenderers who potentially have the necessary capabilities

and capacities to perform the contract;

c) ensure that a limited number of respondents are invited to submit tender offers (usually not less

than three), where the evaluation of tender submissions is resource intensive or to make the

procurement more attractive to potential tenderers due to the demands made on tenderers during

the tender process in preparing a submission; or

d) allow capability and capacity to deliver the required goods, services and construction works to be

evaluated in two stages or to be omitted in the evaluation of tender offers.

Annex A contains guidance on the application of this document and suggestions on good practice.

Annex B provides guidance on how to develop the submission data for a call for expressions of interest

using this document. Annexes C and D offer guidance on the evaluation of expressions of interest and

the structuring of evaluation reports, respectively.

ISO 10845-2 establishes the manner in which calls for expressions of interest should be formatted

and compiled. The standard conditions contained in this document can, by reference, be readily

incorporated in procurement documents formatted and compiled in accordance with the provisions of

ISO 10845-2.

ISO 10845-4:2021(E)

This document is part of the ISO 10845 series which covers various aspects of procurement within the

construction industry. Each part of the ISO 10845 series relates to a different aspect of procurement.

The objective of the ISO 10845 series is to provide a generic and standard set of processes, procedures

and methods for a procurement system that is fair, equitable, transparent, competitive and cost-

effective and which can be used to promote objectives additional to those associated with the immediate

objective of the procurement itself.

ISO 10845-4:2021(E)
4 General requirements
4.1 Actions

The employer and each respondent submitting an expression of interest shall comply with the standard

conditions for calling for an expression of interest in this document. In their dealings with each other,

they shall discharge their duties and obligations, as set out in Clauses 5 and 6, in a timely manner

and with integrity, behave equitably, honestly and transparently, and not engage in anti-competitive

practices.

The employer and the respondent and all their agents and employees involved in the submission process

shall avoid conflicts of interest and where a conflict of interest is perceived or known, declare any such

conflict of interest, indicating the nature of such conflict. Respondents shall declare any potential

conflict of interest in their submissions. Employees, agents and advisors of the employer shall declare

any conflict of interest to whoever is responsible for overseeing the procurement process at the start of

any deliberations relating to the procurement process or as soon as they become aware of such conflict,

and abstain from any decisions where such conflict exists or recuse themselves from the procurement

process, as appropriate.

The respondent shall not make a submission without having a firm intention and the capacity to

proceed with the next stage of the procurement process.

NOTE 1 A conflict of interest can exist even if there are no improper acts as a result of it. This can arise due to

a conflict of roles which can provide an incentive for improper acts in some circumstances or positions. A conflict

of interest can create an appearance of impropriety that can undermine confidence in the ability of that person to

act properly in said circumstance or position.

NOTE 2 Conflicts of interest with respect to those engaged in the procurement process include direct, indirect

or family interests in the tender or outcome of the procurement process and any personal bias, inclination,

obligation, allegiance or loyalty which can in any way affect any decisions taken.

4.2 Supporting documents

The documents issued by the employer for the purpose of obtaining expressions of interest are listed in

the submission data.
4.3 Interpretation

The submission data and additional requirements contained in the submission schedules that are

included in the returnable documents are deemed to be part of the conditions for the calling for

expressions of interest.
4.4 Communication and employer's agent

Each communication between the employer and a respondent shall be to or from the employer's agent

only, and in a form that can be readily read, copied and recorded, and in the language stated in the

submission data. The employer shall not take any responsibility for non-receipt of communications from

or by a respondent. The name and contact details of the employer's agent are stated in the submission

data.
5 Respondent's obligations
5.1 Eligibility

Submit an expression of interest only if the respondent satisfies the eligibility criteria stated in the

as “ORIGINAL” and “COPY”. Each package shall state, on the outside, the employer's address and

identification details stated in the submission data, as well as the respondent's name and contact

address.

Accept that the employer does not assume any responsibility for the misplacement or premature

opening of the submission if the outer package is not sealed and marked as stated.

5.8 Information and data to be completed

Accept that submissions which do not provide all the data or information requested, completely and in

the form required, may be regarded by the employer as being non-responsive.
5.9 Closing time

Ensure that the employer receives the submissions at the address specified in the submission data

not later than the closing time stated in the submission data. Proof of posting shall not be accepted as

proof of delivery. The employer shall not accept submissions submitted by telegraph, telex, facsimile or
