The name, identification and number of lots (contracts) of this RFB are specified in the BDS.

1.2          Throughout this bidding document:

(b)         if the context so requires, “singular” means “plural” and vice versa; and

The Borrower intends to apply a portion of the funds to eligible payments under the contract for which this bidding document is issued.

2.2           Payment by the Bank will be made only at the request of the Borrower and upon approval by the Bank in accordance with the terms and conditions of the Loan (or other financing) Agreement. The Loan (or other financing) Agreement prohibits a withdrawal from the Loan account for the purpose of any payment to persons or entities, or for any import of goods, if such payment or import is prohibited by decision of the United Nations Security Council taken under Chapter VII of the Charter of the United Nations. No party other than the Borrower shall derive any rights from the Loan (or other financing) Agreement or have any claim to the proceeds of the Loan (or other financing).

3.      Fraud and Corruption

3.1            The Bank requires compliance with the Bank’s Anti-Corruption Guidelines and its prevailing sanctions policies and procedures as set forth in the WBG’s Sanctions Framework, as set forth in Section VI.

3.2            In further pursuance of this policy, Bidders shall permit and shall cause their agents (where declared or not), subcontractors, subconsultants, service providers, suppliers, and their personnel, to permit the Bank to inspect all accounts, records and other documents relating to any initial selection process, prequalification process, bid submission, proposal submission, and contract performance (in the case of award), and to have them audited by auditors appointed by the Bank.

4.      Eligible Bidders

4.1          A Bidder may be a firm that is a private entity, a state-owned enterprise or institution subject to ITB 4.6, or any combination of such entities in the form of a joint venture (JV) under an existing agreement or with the intent to enter into such an agreement supported by a letter of intent. In the case of a joint venture, all members shall be jointly and severally liable for the execution of the entire Contract in accordance with the Contract terms. The JV shall nominate a Representative who shall have the authority to conduct all business for and on behalf of any and all the members of the JV during the Bidding process and, in the event the JV is awarded the Contract, during contract execution. Unless specified in the BDS, there is no limit on the number of members in a JV.

4.2           A Bidder shall not have a conflict of interest. Any Bidder found to have a conflict of interest shall be disqualified. A Bidder may be considered to have a conflict of interest for the purpose of this Bidding process, if the Bidder:

(b)      receives or has received any direct or indirect subsidy from another Bidder; or

(c)      has the same legal representative as another Bidder; or

(d)      has a relationship with another Bidder, directly or through common third parties, that puts it in a position to influence the Bid of another Bidder, or influence the decisions of the Purchaser regarding this Bidding process; or

(f)       or any of its affiliates has been hired (or is proposed to be hired) by the Purchaser or Borrower for the Contract implementation; or

(g)      would be providing goods, works, or non-consulting services resulting from or directly related to consulting services for the preparation or implementation of the project specified in the BDS ITB 2.1 that it provided or were provided by any affiliate that directly or indirectly controls, is controlled by, or is under common control with that firm; or

(h)      has a close business or family relationship with a professional staff of the Borrower (or of the project implementing agency, or of a recipient of a part of the loan) who: (i) are directly or indirectly involved in the preparation of the bidding document or specifications of the Contract, and/or the Bid evaluation process of such Contract; or (ii) would be involved in the implementation or supervision of such Contract unless the conflict stemming from such relationship has been resolved in a manner acceptable to the Bank throughout the Bidding process and execution of the Contract.

4.3           A firm that is a Bidder (either individually or as a JV member) shall not participate in more than one Bid, except for permitted alternative Bids. This includes participation as a subcontractor. Such participation shall result in the disqualification of all Bids in which the firm is involved. A firm that is not a Bidder or a JV member, may participate as a subcontractor in more than one Bid.

4.4           A Bidder may have the nationality of any country, subject to the restrictions pursuant to ITB 4.8.

This criterion also shall apply to the determination of the nationality of proposed subcontractors or subconsultants for any part of the Contract including related Services.

The list of debarred firms and individuals is available at the electronic address specified in the BDS.

4.6          Bidders that are state-owned enterprises or institutions in the Purchaser’s Country may be eligible to compete and be awarded a Contract(s) only if they can establish, in a manner acceptable to the Bank, that they (i) are legally and financially autonomous (ii) operate under commercial law, and (iii) are not under supervision of the Purchaser.

4.7          A Bidder shall not be under suspension from Bidding by the Purchaser as the result of the operation of a Bid–Securing Declaration or Proposal-Securing Declaration.

4.8           Firms and individuals may be ineligible if so indicated in Section V and (a) as a matter of law or official regulations, the Borrower’s country prohibits commercial relations with that country, provided that the Bank is satisfied that such exclusion does not preclude effective competition for the supply of goods or the contracting of works or services required; or (b) by an act of compliance with a decision of the United Nations Security Council taken under Chapter VII of the Charter of the United Nations, the Borrower’s country prohibits any import of goods or contracting of works or services from that country, or any payments to any country, person, or entity in that country.

4.9           A Bidder shall provide such documentary evidence of eligibility satisfactory to the Purchaser, as the Purchaser shall reasonably request.

4.10       A firm that is under a sanction of debarment by the Borrower from being awarded a contract is eligible to participate in this procurement, unless the Bank, at the Borrower’s request, is satisfied that the debarment;

30.3      Provided that a Bid is substantially responsive, the Purchaser shall rectify quantifiable nonmaterial nonconformities related to the Bid Price.  To this effect, the Bid Price shall be adjusted, for comparison purposes only, to reflect the price of a missing or non-conforming item or component in the manner specified in the BDS.

(b)         if there is an error in a total corresponding to the addition or subtraction of subtotals, the subtotals shall prevail and the total shall be corrected; and

(c)          if there is a discrepancy between words and figures, the amount in words shall prevail, unless the amount expressed in words is related to an arithmetic error, in which case the amount in figures shall prevail subject to (a) and (b) above.

This is the Bid of the Bidder that meets the qualification criteria and whose Bid has been determined to be:

(a)   substantially responsive to the bidding document; and

(b)   the lowest evaluated cost.

34.2      To evaluate a Bid, the Purchaser shall consider the following:

34.5      The Purchaser’s evaluation of a Bid will exclude and not take into account:

(a)          in the case of Goods manufactured in the Purchaser’s Country, sales and other similar taxes, which will be payable on the goods if a contract is awarded to the Bidder;

34.6      The Purchaser’s evaluation of a Bid may require the consideration of other factors, in addition to the Bid Price quoted in accordance with ITB 14. These factors may be related to the characteristics, performance, and terms and conditions of purchase of the Goods and Related Services. The effect of the factors selected, if any, shall be expressed in monetary terms to facilitate comparison of Bids, unless otherwise specified in the BDS from amongst those set out in Section III, Evaluation and Qualification Criteria. The criteria and methodologies to be used shall be as specified in ITB 34.2(f).

35.  Comparison of Bids

 

35.1       The Purchaser shall compare the evaluated costs of all substantially responsive Bids established in accordance with ITB 34.2 to determine the Bid that has the lowest evaluated cost.

The evaluation of prices shall not take into account custom duties and other taxes levied on imported goods quoted CIP and sales and similar taxes levied in connection with the sale or delivery of goods.

36.  Abnormally Low Bids

 

36.1      An Abnormally Low Bid is one where the Bid price, in combination with other constituent elements of the Bid, appears unreasonably low to the extent that the Bid price raises material concerns with the Purchaser as to the capability of the Bidder to perform the Contract for the offered Bid price.

36.2      In the event of identification of a potentially Abnormally Low Bid, the Purchaser shall seek written clarification from the Bidder, including a detailed price analyses of its Bid price in relation to the subject matter of the contract, scope, delivery schedule, allocation of risks and responsibilities and any other requirements of the bidding document.

The determination shall not take into consideration the qualifications of other firms such as the Bidder’s subsidiaries, parent entities, affiliates, subcontractors (other than specialized subcontractors if permitted in the bidding document), or any other firm(s) different from the Bidder.

37.3       An affirmative determination shall be a prerequisite for award of the Contract to the Bidder. A negative determination shall result in disqualification of the Bid, in which event the Purchaser shall proceed to the Bidder who offers a substantially responsive Bid with the next lowest evaluated cost to make a similar determination of that Bidder’s qualifications to perform satisfactorily.

38.  Purchaser’s Right to Accept Any Bid, and to Reject Any or All Bids

Section VI - Fraud and Corruption

(Section VI shall not be modified)

 

  1. Purpose
    • The Bank’s Anti-Corruption Guidelines and this annex apply with respect to procurement under Bank Investment Project Financing operations.
  2. Requirements
  • The Bank requires that Borrowers (including beneficiaries of Bank financing); bidders (applicants/proposers), consultants, contractors and suppliers; any sub-contractors, sub-consultants, service providers or suppliers; any agents (whether declared or not); and any of their personnel, observe the highest standard of ethics during the procurement process, selection and contract execution of Bank-financed contracts, and refrain from Fraud and Corruption.

 

  • To this end, the Bank:
  1. Defines, for the purposes of this provision, the terms set forth below as follows:
  2. “corrupt practice” is the offering, giving, receiving, or soliciting, directly or indirectly, of anything of value to influence improperly the actions of another party;
  3. “fraudulent practice” is any act or omission, including misrepresentation, that knowingly or recklessly misleads, or attempts to mislead, a party to obtain financial or other benefit or to avoid an obligation;
  • “collusive practice” is an arrangement between two or more parties designed to achieve an improper purpose, including to influence improperly the actions of another party;
  1. “coercive practice” is 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;
  2. “obstructive practice” is:
  • deliberately destroying, falsifying, altering, or concealing of evidence material to the investigation or making false statements to investigators in order to materially impede a Bank investigation into allegations of a corrupt, fraudulent, coercive, or collusive practice; and/or threatening, harassing, or intimidating any party to prevent it from disclosing its knowledge of matters relevant to the investigation or from pursuing the investigation; or
  • acts intended to materially impede the exercise of the Bank’s inspection and audit rights provided for under paragraph 2.2 e. below.
  1. Rejects a proposal for award if the Bank determines that the firm or individual recommended for award, any of its personnel, or its agents, or its sub-consultants, sub-contractors, service providers, suppliers and/ or their employees, has, directly or indirectly, engaged in corrupt, fraudulent, collusive, coercive, or obstructive practices in competing for the contract in question;
  2. In addition to the legal remedies set out in the relevant Legal Agreement, may take other appropriate actions, including declaring misprocurement, if the Bank determines at any time that representatives of the Borrower or of a recipient of any part of the proceeds of the loan engaged in corrupt, fraudulent, collusive, coercive, or obstructive practices during the procurement process, selection and/or execution of the contract in question, without the Borrower having taken timely and appropriate action satisfactory to the Bank to address such practices when they occur, including by failing to inform the Bank in a timely manner at the time  they knew of the practices;
  3. Pursuant to the Bank’s Anti- Corruption Guidelines, and in accordance with the Bank’s prevailing sanctions policies and procedures, may sanction a firm or individual, either indefinitely or for a stated period of time, including by publicly declaring such firm or individual ineligible (i) to be awarded or otherwise benefit from a Bank-financed contract, financially or in any other manner;[1] (ii) to be a nominated[2] sub-contractor, consultant, manufacturer or supplier, or service provider of an otherwise eligible firm being awarded a Bank-financed contract; and (iii) to receive the proceeds of any loan made by the Bank or otherwise to participate further in the preparation or implementation of any Bank-financed project;
  4. Requires that a clause be included in bidding/request for proposals documents and in contracts financed by a Bank loan, requiring (i) bidders (applicants/proposers), consultants, contractors, and suppliers, and their sub-contractors, sub-consultants, service providers, suppliers, agents personnel, permit the Bank to inspect[3] all accounts, records and other documents relating to the procurement process, selection and/or contract execution, and to have them audited by auditors appointed by the Bank.

2.1       WORK INCLUDED

Work of this Section consists of the design and supply of conductors as specified.

 

2.2       TERMINOLOGY

Unless otherwise defined below technical terminology is defined in IEC-50 (latest edition).

Sag

Sag of a length of conductor supported at each end only, shall mean the maximum

vertical distance in the span measured between the conductor and the hypothetical

straight line joining the two points of support.

Initial Sag

Initial Sag of a conductor shall mean the sag at the time of installation prior to being subjected to any loading or long term creep.

Final Sag

Final Sag of a conductor shall mean the sag as may be expected after having been subjected to the design loading or after being in service over a minimum period of ten (10) years, whichever causes the greater permanent stretch.

 

2.3       QUALITY ASSURANCE

Except where otherwise specified or approved the GzTACSR Conductors shall be tested in accordance with IEC 61089.

 

 2.4      SUBMITTALS

Submit the following items:

List of precise conductor details, including but not limited to type, code name, cross-section areas, diameters, number of strands, coefficients of expansion, modulus of elasticity, electrical resistance to alternating current and direct current, current rating, annealing temperature, rated tensile strength, mass and as applicable, details of alloy and grease.

Conductor design sag and tension data for the design wire heights, for initial and final loaded and unloaded conditions at various ruling span lengths and in temperatures ranging from 10ºC to 75ºC in 5ºC increment. The ruling span increment shall not be greater than 25 meters. Consider 10 year creep in calculation.

Design wind pressures will be provided by the Engineer.

Detail drawing and descriptions of proposed stringing methods.

Description of tools and erection equipment to be used for stringing.

Manufacturer’s company profile, experience record, quality certification and authorization form.

The test reports showing compliance of GzTACSR conductor according to IEC 61089, 62420, 62004 and ASTM B941 technical data schedules and the technical specifications.

Stringing sag data in tabular format listing each ruling span section and length, the sags and tensions for that ruling span, and the sags for each individual span within each ruling span section. The temperature increment shall be 5ºC.

 

 2.5      PRODUCT DELIVERY AND HANDLING

2.5.1  Delivery of Materials and Equipment

Ship conductor on reels suitable for export shipment and to suit the type and length of conductor being shipped. Nail or otherwise firmly attach lagging at each end of the reel flange and secure with not less than two steel straps. Ensure there is no space between lagging.

Over and above the specified shipping marks and address stamp the following on aluminium plates and firmly attach to each side of reel.

Serial number

Length of conductor in meters

Conductor size and type

Gross, fare, net and legal weight in metric units

Volume in cubic meters

Also place above information on typed tags and attach to inside of reel or lead end of conductor.

Ensure reels have large clear arrows indications roll direction.

 

2.5.2  Handling of Material

When transported by fork truck, ensure hub axis is parallel to direction of travel. When lifting by crane or hoist use a spreader bar in conjunction with a bar through the hub.

Do not lift or move by threading chains, ropes or wires through the hub or by slings around the lagging. Non-empty reels shall always be kept upright. Do not drop reels.

Do not set or roll reels over rough surfaces. Always roll reels in the direction of the arrow.

Empty reels shall be removed from the site and either returned to the manufacturer or disposed on in a satisfactory manner.

 

 2.6      PRODUCTS

2.6.1    General

The stranding of each layer of the conductor shall be as close and even as possible. The outermost layer shall be right-handed.

  • List of Assumptions for Design of tower Members

(a)        Shear is distributed equally between the two members of a double web system, i.e., warren system.

(b)        Shear is carried by the diagonal member under tension in a Pratt system with members designed for tension only, the other member being inactive.

(c) Torsion shears applied at cross arm level for square tower are resisted by all the four tower faces equally.

(d) Plan members at levels other than those at which external loads are applied or where the leg slope changes, are designated as redundant members.

(e) Any face of the tower subjected to external loads lies in the same plane, so far as the analysis of the particular face is concerned, except earth wire cross arm and peak.

(f) Transverse loads are shared by the members on the transverse faces of the towers equally. Similarly, the longitudinal loads are shared equally by the two longitudinal faces.

(g) The torsion loads are resisted by all the four faces in inverse proportion of the width of each face.

(h) All members, placed horizontally or at an angle less than 15° to the horizontal, will be checked independently for specified point on load, causing bending stresses.

  • Unit Stresses

 

General

Members and accessories shall be of such size, shape and length as to preclude damage or failure from vibration, stress reversal or fatigue.

 

Any recognized design practice may be used provided that all parts of structures are designed so that unit stresses in members and connections produced by most critical combination of specified design loads when multiplied by appropriate overload factors do no exceed values derived from the following paragraphs.

 

Compression

Compressive stress – The values given in Section C of the American Society of Civil Engineers Manual N° 10-97, “Guide for Design of Latticed Steel Transmission Towers”.

 

Tension

Tensile stress: The minimum guaranteed yield stress

 

The net area of member is used when computing the tensile strength. In deducting the area of bolt holes from the gross area of member, the diameter of the hole (for calculation purposes) is taken as 1.5 millimetres (1.5 mm) larger that the nominal diameter of the bolt.

 

The net area of a single angle tie member connected through one leg only, or double angle connected on one side of a gusset plate, is calculated as follows:

 

Net Area = 3x2 + 4xy

                     3x + y

 

Where  x = net area of connected leg(s)

            y = net area of outstanding leg(s)

 

In multi bolt connections with more than one (1) gauge line, the net section of the connected leg is the least area which can be obtained by deducting from the gross, sectional area the area of all holes cut by any straight, diagonal, or zig-zag line across the member. In determining the total area of the holes to be deducted from the gross section, the full area of the first hole should be counted, plus a fractional part Z, of each succeeding hole cut by the line of holes under consideration.

 

The value of Z may be determined from the formula:

 

                                    Z=1 -  S2

                                             4GH

 

where S = longitudinal spacing (stagger) between two successive holes in the line of holes under consideration

G = traverse spacing (gauge) between the same two holes for S

H = diameter of hole. Bolt diameter plus 1.5 mm

 

The net area of single angle tension members with both legs connected is calculated as described above except that for holes in opposite legs of angles the value of G should be the sum of the gauges from the back of the angle less the thickness of the angle.

 

The net area used to determine tensile strength shall not exceed 85% of the gross area.

 

In determining the net section across plug or slot welds, the metal shall not be considered as adding to the net area.

 

Bending

 

Maximum secondary bending stress on extreme fibres: minimum guaranteed yield stress.

 

Maximum primary bending stresses shall be determined using appropriate bending stress formula.

 

Members simultaneously subjected to both axial compression and bending stress shall be designed to meet the following requirements:

 

fc  +    fb              =< 1.0

Fc    Fb(1-fc/Fe)

 

where fc = actual axial compressive stress (axial force divided by the effective cross-sectional area)

 

fb = actual bending stress, tension and compression of extreme fibres. (Bending moment divided by the section modulus)

 

Fb = 1970 x 10-6 kPa

             (L/R)2

 

The slenderness ratio (L/R) is computed about the axis of bending.

 

Shear

 

Maximum shear stress: 0.58 (zero point five eight) times the minimum guaranteed yield stress.

 

Bearing

 

Maximum bearing stress in abutting members: minimum ultimate tensile strength.

 

Maximum bearing stress in bolt holes based on the nominal bolt diameter and member thickness; either the applicable yield stress times two (2.0 Fy) or minimum ultimate tensile strength times one point two four (1.24 Fu), whichever is the least.

 

Bearing capacity is related to either the capacity of the member or the connection bolt, whichever is the lower value.

 

 

 

Tower Bolts

 

Connections shall be designed for bearing and shear, not friction.

 

(i) Maximum tensile stress on tensile stress area: for bolts having a specified proof load stress, the tensile stress does not exceed the  proof-load stress (Fp) determined by the length measurement method. For bolts having no proof load stress specified, the tensile stress shall not exceed 0.6 Fu (point six of the ultimate tensile strength)

(ii) Maximum shear stress on shank area: for bolts having a specified proof-load stress, the shear stress does not exceed 0.7 Fp for joint length up to 400 mm and does not exceed 0.6 Fp for joint length greater than 400 mm. For bolts having no proof load stress specified, the shear stress does not exceed 0.5 Fu for all joint lengths. (Joint length is the distance between centers of the leading and the trailing bolts in the connection).

(iii) Maximum bearing stress: bearing stress does not exceed twice the proof-load stress (2.0 Fp) or one point two times the ultimate tensile strength (1.2 Fu) whichever is the least.

 

  • Slenderness Ratios L/R

The maximum ratio of un-braced or unsupported length (L) to the least radius of gyration (R) of a member shall not exceed:

 

For Compression Members

Leg members, ground wire peak and cross arm chord members 120

Bracing and other member having calculated stress 200

Redundant or Secondary members without calculated stress 250

 

For Tension Members

All Tension Members 400

 

In assessing the unsupported length of compression members, the lengths are determined from working point to working point on the design drawings. Multiple bolt connections shall not be considered to offer joint restraints unless connection is made to a member having adequate flexural resistance to resist rotation of the joint. Connections made through gusset plates shall not be considered to provide joint restraint. Secondary members may be considered as providing full support in the plane in which they are placed. Double Warren Systems which are bolted at their intersections may be considered supported in both directions at these points.

 

  • Redundants

These members are designed for a force resulting from 2-1/2% of the load in the member being restrained, assessed in accordance with the method given in Figure 1 of Appendix 1.

 

Redundant members introduced to limit the slenderness ratio of tension members need only meet the requirements for limiting slenderness ratio.

 

 

  • Cross Arm Design for Longitudinal Loads
