5.6 General stipulations regarding the design and development of switchgear

5.6.1 Introduction The RMU shall meet the criteria for compact, metal-enclosed outdoor switchgear in accordance with IEC 62271-200. It shall include, within the same metal enclosure, the number of MV functional units required for connection, power supply and protection of transformers, i.e.

- 2 “network” switch disconnectors, - 1 “transformer protection” feeders, - earthing switches.

5.6.2 Switchgear The switchgear and busbar shall all be contained in an earth screened cast resin enclosure filled with SF6 at either 0.35/0.55 bar G relative pressure to ensure the insulation and breaking functions. Sealed for life, the

58

enclosure shall meet the “sealed pressure system” criterion in accordance with the IEC 298 standard (appendix GG § 2.3 and 3.3): a system for which no handling of gas is required throughout the 25 years of service life. There shall be no requirement to ‘top up‘ the SF6 gas. In addition, manufacturer shall confirm that maximum leakage rate is lower than 0,1 % / year. It shall provide full insulation, making the switchgear insensitive to the environment (temporary flooding, high humidity…). Thus assembled, the active parts of the switchgear shall be maintenance-free and the unit shall be minimal-maintenance. Welded steel/stainless steel SF6 enclosures or a dual skin type design shall not be acceptable. The cast resin enclosure and RMU housing shall have a design such that in the event of an internal arc fault, the operator shall be safe. This should be in accordance with IEC 62271-200. The switchgear enclosure shall be Dark Grey Code 632 to BS 381C. Each switchboard shall be identified by an appropriately sized label which clearly indicates the functional units and their electrical characteristics. The switchgear and switchboards shall be designed so that the position of the different devices is visible to the operator on the front of the switchboard and operations are visible as well. The MV system shall be totally encapsulated in a resin insulating medium. There shall be no access to exposed MV conductors. In accordance with the standards in effect, the switchboards shall be designed so as to prevent access to all live parts during operation without the use of tools. 5.6.3 Dielectric medium SF6 gas shall be used for the dielectric medium for MV RMUs. Oil filled switchgear will not be considered. SF6 gas used for the filling of the RMU shall be in accordance with IEC 376. It is preferable to fit an absorption material in the tank to absorb the moisture from the SF6 gas and to regenerate the SF6 gas following arc interruption. The SF6 insulating medium shall be constantly monitored via a gas pressure indicator offering a simple go, no-go indication. 5.6.4 Earthing of metallic parts There shall be continuity between the cast resin earth screen and metallic parts of the switchboard and cables so that there is no electric field pattern in the surrounding air, thereby ensuring the safety of people. 5.6.5 Earthing of the main circuit The cables shall be earthed by an integral earthing switch with short-circuit making capacity, in compliance with IEC 129 standard. The earthing switch can only be operated when the switch is open.

Scope of Work, but the quantity of work which is not measured in any units.

2.3.4 A rate, sum, percentage fee and/or price as applicable, is to be entered against each item in the pricing

schedule. An item against which no price is entered will be considered as a no offer and will not be

evaluated.

2.3.5 The rates, sums, percentage fees and prices in the pricing schedule are to be fully inclusive prices under the several items. Such prices and rates are to cover all costs and expenses that may be required in and for the execution of the work described, and shall cover the cost of all general risks, liabilities, and obligations set forth or implied in the tender, as well as overhead charges and profit.

2.3.6 Where quantities are given in the pricing schedule, these are provisional and do not necessarily represent

the actual amount of work to be done. The quantities of work accepted and certified for payment will be used

for determining payments due and not the quantities given in the pricing schedule. In respect of time-based

services, the allocation of staff must be agreed with the employer before such services are rendered.

2.3.7 All rates, sum, percentage fees or prices (as applicable) tendered in the pricing schedule shall be final and

binding and shall not be subject to any variation throughout the period of the contract.

2.3.8.1 The pricing to be indicated in Section A is based on estimated quantities from the previous year and is only

used for evaluation purposes.

SECTION 4.6 MBD 9: CERTIFICATE OF INDEPENDENT BID DETERMINATION

1. This Municipal Bidding Document (MBD) must form part of all bids¹ invited.

2. Section 4 (1) (b) (iii) of the Competition Act No. 89 of 1998, as amended, prohibits an agreement between, or concerted practice by, firms, or a decision by an association of firms, if it is between parties in a horizontal relationship and if it involves collusive bidding (or bid rigging). ² Collusive bidding is a pe se prohibition meaning that it cannot be justified under any grounds.

3. Municipal Supply Regulation 38 (1) prescribes that a supply chain management policy must provide

measures for the combating of abuse of the supply chain management system, and must enable the accounting officer, among others, to:

a. take all reasonable steps to prevent such abuse; b. reject the bid of any bidder if that bidder or any of its directors has abused the supply chain

management system of the municipality or municipal entity or has committed any improper conduct in relation to such system; and

c. cancel a contract awarded to a person if the person committed any corrupt or fraudulent act during the bidding process or the execution of the contract.

4. This MBD serves as a certificate of declaration that would be used by institutions to ensure that, when bids

are considered, reasonable steps are taken to prevent any form of bid-rigging.

5. In order to give effect to the above, the attached Certificate of Bid Determination (MBD9) must be completed and submitted with the bid:

¹ Includes price quotations, advertised competitive bids, limited bids and proposals. ² Bid rigging (or collusive bidding) occurs when businesses, that would otherwise be expected to compete, secretly conspire to raise prices or lower the quality of goods and / or services for purchasers who wish to acquire goods and / or services through a bidding process. Bid rigging is, therefore, an agreement between competitors not to compete.

116
