INSTRUCTIONS TO APPLICANTS

1. General

1.1 The Employer, as defined in the Prequalification Data, intends using the proceeds of a loan

from the European Bank for Reconstruction and Development (the Bank), to finance

contract(s) for which this Invitation for Prequalification is issued. Payments by the Bank will

be made only at the request of the Employer and upon approval by the Bank and will be

subject in all respects to the terms and conditions of the Loan Agreement. The proceeds of the

Bank’s loan will not be used for payments to persons or entities, or for any import of goods, if

such payment or import is prohibited by a decision of the United Nations Security Council

taken under Chapter VII of the Charter of the United Nations.

1.2 The Employer intends prequalifying firms and joint ventures to tender for the contract(s)

outlined in the Prequalification Data.

1.3 The tendering schedule is outlined in the Prequalification Data.

1.4 General information on the location, scope and duration of the contract and other relevant data

2. Eligibility and qualification criteria

2.1 Subject to paragraph 1.1, prequalification is open to firms and joint ventures from any country

or countries, unless specified otherwise in the Prequalification Data.

2.2 Prequalification will be based on the applicant meeting the minimum pass/fail criteria

regarding the applicant's general and particular experience, personnel and equipment

capabilities, and financial position, specified in the Prequalification Data, as demonstrated by

the applicant's responses in the forms attached to the Letter of Application and other requested

documentation. Specific requirements for joint ventures are also set forth in the

Prequalification Data. The Employer reserves the right to waive minor deviations from the

criteria, if they do not materially affect the capability of an applicant to perform the contract.

2.3 When the applicant intends obtaining highly specialised inputs (essential for execution of the

contract) from specialised subcontractors, application forms shall be completed for such

subcontractors and their inputs.

2.4 No affiliate of the Employer shall be eligible to tender or participate in a tender in any capacity

whatsoever, unless it can be demonstrated that there is not a significant degree of common

ownership, influence or control between the Employer and the affiliate.

2.5 Where a firm, its affiliates or parent company, in addition to consulting, also has the capability

to manufacture or supply goods or to construct works, that firm, its affiliates or parent

company normally cannot be a supplier of goods or works on a project for which it provides

consulting services, unless it can be demonstrated that there is not a significant degree of

common ownership, influence or control.


page 8 of 70

2.6 An applicant shall not be eligible to participate where it has been determined to have engaged

in corrupt, fraudulent, coercive or collusive practices in accordance with sub-paragraph 4.9(c).

3. Preparation and submission of applications

3.1 If specified in the Prequalification Data, a clarification meeting and/or site visit will be held at

the time, date and place specified. Prospective applicants may request in writing clarification

of the project requirements and the criteria for qualification at any time up to 21 days prior to

the deadline set for the submission of applications. The written responses will be sent to all

prospective applicants that have received the prequalification documents (including the query

but without identifying the source).

3.2 All information requested for prequalification shall be provided in the language specified in

the Prequalification Data. Where information is provided in another language it shall be

accompanied by a translation into the language of the prequalification documents. This

translation will govern and be used for interpreting the information. Information should be

submitted in the formats specified in the application forms in these prequalification

documents.

3.3 The application for prequalification shall consist of the following:

(a) the Letter of Application

(b) the forms and documentation specified in the Prequalification Data.

3.4 Failure to provide information which is essential to evaluate the applicant's qualifications or to

provide timely clarification or substantiation of the information supplied may result in

disqualification of the applicant.

3.5 Submission of applications for prequalification must be received in sealed envelopes, which

shall be delivered either by hand or by registered mail, to the address specified in the

Prequalification Data no later than the date specified in the Prequalification Data, and shall

bear the identification specified in the Prequalification Data. The Employer reserves the right

to accept or reject late applications.

3.6 The name and mailing address of the applicant shall be clearly marked on the envelope.


page 9 of 70

4. Prequalification and tendering

4.1 The Employer reserves the right to:

1 amend the scope and value of any contract(s) to be tendered, in which event only those

prequalified applicants who meet the amended requirements will be invited to tender for

the contract(s).

2 reject or accept any application; and

3 cancel the prequalification process and reject all applications.

The Employer shall neither be liable nor be under any obligation to inform the applicant of

the grounds for such action.

4.2 Applicants will be advised in writing by fax or telex, within the period specified in the

Prequalification Data, of the result of their application and of the names of the prequalified

applicants, without giving any reason for the Employer's decision.

4.3 Only firms and joint ventures that have been prequalified under this procedure will be

invited to tender. A firm may apply for prequalification both individually and as part of a

joint venture. However, a prequalified firm or a member of a prequalified joint venture

may participate as a tenderer in only one tender, either individually or as a partner in a

joint venture, for the contract. Submission or participation by a tenderer in more than one

tender for a contract (other than alternatives which have been permitted or requested) will

result in the disqualification of all tenders for that contract in which the party is involved.

However, this does not limit the inclusion of the same subcontractor in more than one

tender.

4.4 An applicant may be “conditionally prequalified” by the Employer, that is, prequalified

subject to certain specified requirements being met by the applicant prior to a prescribed

deadline, such as: the issuance of the Invitation to Tender. Requirements for “conditional

prequalification” include such factors as:

• revision to a preliminary joint venture agreement;

• substitution of a specialised subcontractor or collaborator which is determined to be

unqualified;

• improving critical project management;

• access to special equipment;

• recruiting experts in specialised fields;

• the applicant’s questionable ability to undertake the proposed contract due to the pending

award of other significant contracts;

• submitting bank reference(s) or evidence of line of credit.

4.5 At the time of submitting their tenders, prequalified tenderers shall update the relevant

information used for prequalification to confirm that they continue to comply with the

qualification criteria and verify that the information previously provided is still valid and


page 10 of 70

correct. A tenderer shall be disqualified if it no longer meets the qualification

requirements at the time of contract award.

4.6 Joint ventures must comply with the following requirements:

(a) The formation of a joint venture after prequalification, and any change in a

prequalified joint venture, will be subject to the written approval of the Employer prior

to the deadline for submission of tenders. Such approval may be denied if (i) partners

withdraw from a joint venture and the remaining partners do not meet the qualifying

requirements; (ii) the level of participation by partners or the structure of the joint

venture is substantially changed; (iii) the new joint venture is not qualified; or (iv) in

the opinion of the Employer, a substantial reduction in competition may result.

(b) Any tender shall be signed so as to legally bind all joint venture partners, jointly and

severally, and any tender shall be submitted with a copy of the joint venture agreement

providing for joint and several liability with respect to the contract.

4.7 The prequalification of a joint venture does not necessarily prequalify any of its partners

individually or as a partner in any other joint venture or association. In case of dissolution

of a joint venture, each of the constituent firms may prequalify if they meet all the

prequalification requirements, subject to the written approval of the Employer prior to the

deadline for submission of tenders.

4.8 Prequalified tenderers will be required to provide a tender security as outlined in the

Prequalification Data. The successful tenderer will be required to provide a performance

security. Details of these securities will be specified in the tender documents.

4.9 The Bank requires that clients (including beneficiaries of Bank loans), as well as tenderers, suppliers, contractors, concessionaires and consultants under Bank-financed contracts,

observe the highest standard of ethics during the procurement and execution of such contracts. In pursuance of this policy, the Bank:

(a) defines, for the purposes of this provision, the terms set forth below as follows:

(i) "corrupt practice" means the offering, giving, receiving, or soliciting, directly or indirectly,

anything of value to influence improperly the actions of another party;

(ii) "fraudulent practice" means any act or omission, including a misrepresentation, that

knowingly or recklessly misleads, or attempts to mislead, a party to obtain a financial or other benefit or to avoid an obligation;

(iii) “coercive practice” means impairing or harming, or threatening to impair or harm, directly or indirectly, any party or the property of the party to influence improperly the actions of a

party;

(iv) “collusive practice” means an arrangement between two or more parties designed to achieve an improper purpose, including influencing improperly the actions of another party;


page 11 of 70

(b) will reject a proposal for prequalification if it determines that an applicant recommended for prequalification has engaged in corrupt, fraudulent, coercive

or collusive practices in competing for the contract in question;

(c) will declare a firm ineligible indefinitely or for a stated period of time, to be prequalified under a Bank-financed contract if it at any time determines that:

• the firm has engaged in corrupt, fraudulent, coercive or collusive practices in competing for, or in executing, a Bank-financed contract; or

• the firm has been found by a judicial process or other official inquiry to have engaged in corrupt, fraudulent, coercive or collusive practices.

rehabilitation of a road), the value retained will be the one specifically related to bridge works.

In case that the applicant was member in a Joint Venture in a contract, the quantities of works

related to the applicant will be assessed the following way:

• where the applicant was performing all the works of a particular category, 100% of the

respective quantity of works is taken into consideration for the purpose of the evaluation;

• where the applicant had a share of more than 33% in the JV where all the resources were

put in common, 100% of the respective quantity of works is taken into consideration for

VOLUME II

The wider objective of this project is to complete maintenance and rehabilitation works on 7

bridges in Dobrogea area, in Romania. Generally speaking, the list of the rehabilitations works

refers to:

• Restoring to a former state and/or capacity

• Improving serviceability (structural and/or functional)

• Strengthening

The purpose of this Volume II is to provide general information which can help in knowing

bridges characteristics, in knowing each type of deterioration, the diagnosis of deterioration

executed on the structures by means of non-destructive and dynamics tests and in understanding

the designed solutions to rehabilitation.

The bridges and structures included in the projects present various static schemes and

configurations. The project includes:

• metallic truss bridges - bridge 7 at Cernavoda, bridge 8 at Borcea;

• precast concrete beam bridge - Bridge no. 10 over railway at Gaiseanca;

• arch bridges (bridge 4 in Poarta Alba, bridge 5 in Ovidiu and bridge 6 in

Basarabi),

• precast concrete beam bridge (bridge 9 in Mangalia);

The rehabilitation and maintenance works included in the Project mainly concern superstructure

and bridge deck, with only limited intervention on infrastructure.

The expected construction period for each Lot or any combination is of 24 months.

In the next paragraphs the main characteristics of all 3 bridges will be described.

Lot 4 – “Rehabilitation works for Bridge no. 07 at Cernavoda, on A2 km 157+600
