1. INTRODUCTION

National Library of South Africa (NLSA) identified as a key priority the need to maintain high

standards of equipment and facilities within its building. Results from the inspection of

problems surrounding electrical infrastructure and need for full compliance identified the need

to appoint service providers to conduct an audit, and consequently develop specifications for

the appointment of electrical contractors to conduct works regarding the aforesaid problems.

Therefore, this document is a result of the audit work undertaken which summarises the

problems and needs required to develop scope and specifications for conducting work

required to undertake this assignment.

2. OBJECTIVES

The objective of the proposed project is to review the key systems including BMS, UPS,

Distribution Boards and other general electrical installations. The current systems have

limitations towards promoting the effective and efficient operations of the general electrical

systems. Consequently they need to overhauled to improve the operation of the Library which

is desirable for its efficient and successful management.

3. BACKGROUND

2

Following the identification by National Library of South Africa, the need to evaluate the

problems associated with electrical management systems which includes UPS, BMS,

Distribution Boards and General electrical installations, service providers were appointed to

undertake the audit. The audit informed the need to undertake specific projects aimed at

improving or solving the electrical problems. Based on the above, the audit identified

numerous non-compliance issues surrounding the problems on the current electrical

infrastructure and its operation.

Circuits, rewiring and testing of the Distribution boards (DBs) is desirable to be done.

Conductors for lights circuits on Building Management (BM) System is currently not working.

Legend Cards which guides the identification of features requiring attention need to be

corrected since these features do not correspond with circuits. Therefore new Legend Cards

should be revised and issued.

Below is a summary of some of the key areas requiring attention:

3.1 UPS

The main server room consists of one 10KVA UPS that supplies only the IT equipment in the

server room. The UPS installed does not serve the purpose because critical equipment such

as CCTV, Access Control, Fire Detection and Security Systems are not connected to this unit.

The UPS batteries of the existing 10KVA unit are also incomplete. Therefore there is a need to

increase the UPS capacity to serve other critical equipment as highlighted above.

3.2 BMS

The Building Management system (BMS) is currently not functioning as it should be, making it

difficult to identify where the faults are and the causes of these faults. This makes it difficult for

the management team to diagnose, manage and address the electrical issues they are facing

in the building. Therefore resulting from the electrical audit which was conducted, the proposal

is that the BMS should be replaced.

3.3 Distribution Boards 3

Circuits rewiring and testing of the DBs is essential. Conductors for lights circuits on Building

Management (BM) System is not working. Legends Cards do not correspond with circuits

therefore new Legends Cards should be issued.

3.4 General Electrical (Plugs, Sockets, Lights, Sensors etc)

The electrical installation is in a functional state in some of the library areas, but the wiring and

contactors inside distribution board fittings needs attendance. The fittings (light fittings,

sockets, switches, circuit breakers, etc.) are recently installed. The luminaires lamps used in

the building are fluorescent lamps, MH and HPS which are not energy efficient compared to

LED. As part of the above, occupational sensors will equally receive attention as highlighted

in this specification. The electrical light fittings (Bulkhead lights) installed on the wall were

stolen. Therefore the proposal is that vandal proof light fitting must be installed along the

ramps. In addition, all IT equipment, Access control, fire detection, CCTV, emergency lights

(escape route) and dedicated plugs must be connected to emergency load (Existing

Generator). See photograph annexure 1.

3.5 Summarised quantities of problems

3.5.1 Currently, 761 lights are neither operating nor working. These lights are categorised as

fluorescent (346), Down Lights (170) and other lights (245) which require attention, within the

overall building. This highlights the status of the problems which are currently experienced and

require attention.

3.5.2 With regard to plugs, there are approximately 94 plugs which are not working. Apart

from these plugs, other problems relate to earthing on some of the plugs, network and blank

covers, replacement and addition of dedicated plugs, rewiring of wires and labelling of these

plugs.

The power trunking must comply with SABS 1197. The Contractor must ensure that the power

trunking is installed to satisfaction of the Department’s representative before commencing with

the wiring of the power trunking.

[The method of installing and wiring of the power trunking must be specified in detail.]

6.13 Power points

Allow for the installation of power points and equipment as listed in the schedule, indicated on

the drawings and described below:

conductors and cable must be listed in the Schedule of Power Points.]

Example: Water Heaters

The Contractor must electrically connect all water heaters as specified and listed in the

Schedule of Power Points.

21

NOTE: The hot water installation must be approved by the Department’s

Representative/Agent. Detail with regard to the size and type of water heaters that must be

provided must be obtained from the Architect.

6.14 Cables

The Contractor shall supply and completely install all distribution cables as indicated on the

drawings, and listed in the Schedule of Cables.

The storage, transportation, handling and laying of the cables shall be according to first class

practice, and the contractor shall have adequate and suitable equipment and labour to ensure

that no damage is done to cables during such operations.

All joints in underground cables and terminations shall be made either by means of compound

filled boxes according to the best established practice by competent cable jointers using first

class materials or by means of approved epoxy-resin pressure type jointing kits such as

“Scotchcast”. Epoxy-resign joints must be made entirely in accordance with the

manufacturer’s instructions and with materials stipulated in such instructions. Low tension

PVC cables are to be made off with sealing glands and materials designed for this purpose

which must be of an approved make. Where cables are cut and not immediately made off, the

ends are to be sealed without delay.

The laying of cables shall not be commenced until the trenches have been inspected and

approved. The cable shall be removed from the drum in such a way that no twisting, tension or

mechanical damage is caused and must be adequately supported at intervals during the

whole operation. Particular care must be exercised where it is necessary to draw cables

through pipes and ducts to avoid abrasion, elongation or distortion of any kind. The ends of

such pipes and ducts shall be sealed to approval after drawing in of the cables.

Backfilling (after bedding) of the trenches is to be carried out with a proper grading of the

material to ensure settling without voids, and the material is to be tamped down after the

addition of every 150mm. The surface is to be made good as required.

22

On each completed section of the laid and jointed cable, the insulation resistance shall be

tested to approval with an approved “Megger” type instrument of not less than 500 V for low

tension cables.

Earth continuity conductors are to be run with all underground cables constituting part of a low

tension distribution system. Such continuity conductors are to be stranded bare copper of a

cross-sectional area equal to at least half that of one live conductor of the cable, but shall not

be less than 4mm² or more than 70mm². A single earth wire may be used as earth continuity

conductor for two or more cables run together, branch earth wires being brazed on where

required.

6.15 Laying, jointing and making off of electrical cables

[The requirements specified hereafter, are aimed essentially at high tension cable but are also

valid for low tension cable, where applicable.]

The use of the term “Inspector”, includes the engineer or inspector of the NLSA or an

empowered person of the concerned supervising consulting engineer’s firm.

After the cable has been laid and before the cable trench is back-filled the inspector must

ensure that the cable is properly bedded and that there is no undesirable material included in

the bedding layer.

All cable jointing and the making off of the cables must only be carried out by qualified

experienced cable jointers. Helpers of the jointers may not saw, strip, cut, solder, etc. The

cable and other work undertaken by them must be carried out under the strict and constant

supervision of the jointer.

Before the Contractor allows the jointer to commence with the jointing work or making off of

the cable (making off is recognized as half a joint) he must take care and ensure:

That he has adequate and suitable material available to complete the joint properly and

efficiently. Special attention must be given to ensure the cable ferrules and cable lugs are of

tinned copper and of sufficient size. The length of the jointing lugs must be at least six times

the diameter of the conductor,

23

That the joint pit is dry and that all loose stones and material are removed,

That the walls and banks of the joint pit are reasonably firm and free from loose material which

can fall into the pit,

That the necessary coffer-dams or retaining walls are made to stop the flow of water into the

joint pit,

That the joint pit is provided with suitable groundsheets so that the jointing work is carried out

in clean conditions,

That the necessary tents or sails are installed over the joint pit to effectively avert unexpected

rainfall and that sufficient light or lighting is provided,

That the necessary means are available to efficiently seal the jointing or cable end when an

unexpected storm or cloudburst occurs, regardless of how far the work has progressed,

That the cables and other materials are dry, undamaged and in all respects are suitable for the

joint work or making off,

That the heating of cable oil, cable compound, plumbers metal and solder is arranged that

they are at the correct temperature when required so that the cable is not unnecessary

exposed to the atmosphere and consequently the ingress of moisture (care must be taken of

overheating)

Flow temperatures of cable oil and compound must be determined with suitable thermometers.

Cable oil and compound must not be heated to exceed the temperatures given on the

containers and precaution must be taken to ensure that the tin is not overheated in one

position. The whole mass must be evenly and proportionally heated. (Temperatures of solder

and plumbers metal may be tested with brown paper (testing time: 3 seconds). The paper

must colour slightly - not black or burnt).

Before the paper-insulated cables are joined, they must be tested for the presence of moisture

by the cable jointers test. This consists of the insertion of a piece of unhandled insulated

impregnated paper tape in warm cable oil heated to a temperature of 130 ± 5°C.

24

Froth on the surface of the oil is an indication that moisture is present in the impregnated

insulation and the amount of the froth gives an indication of the moisture present.

If the cable contains moisture or is found to be otherwise unsuitable for jointing or making of

the inspector is to be notified immediately and he will issue the necessary instruction to cope

with the situation.

The joint or making off of paper insulated cables must not be commenced during rainy

weather.

Once a joint is in progress the jointer must proceed with the joint until it is complete and before

he leaves the site.

The jointer must ensure that the material and his tools are dry at all times, reasonably clean

and absolutely free from soil.

Relating to the jointing of the cable the following requirements apply:

All jointing must be carried out in accordance with recognized and tried techniques and comply

strictly with the instructions given by the supplier of the jointing kit.

The cables must be twisted by hand so that the cores can be joined according to the core

numbers. If necessary the cable is to be exposed for a short distance to accomplish this.

Under no circumstances may the cores in a joint be crossed so as to enable cores to be joined

according to the core numbers. If it is not possible to twist the cables so that the preceding

requirements can be met, then cores are to be joined in the normal way without any

consideration of the core numbers.

Normally the cables will have profile conductors. The conductors shall be pinched with gas

pliers to form a circular section, bound with binding wire so that they do not spread, and then

tinned before jointing.

Jointing ferrules, the length of which are at least 6 times the diameter of the conductors, must

be slid over the conductor ends to be joined and pinched tightly. Then they are soldered by

means of the ladle process whilst being pinched further closed.

25

Use resin only as a flux. The slot opening in the ferrule must be completely filled, including all

depressions.

Remove all superfluous metal with a cloth dipped in tallow. Work during the soldering process

must be from top to bottom. Rub the ferrule smooth and clean with aluminum oxide tape after

it has cooled down to ensure that there are not any sharp points or edges.

NB: The spaces between the conductor strands must be completely filled by soldering

process and must be carried out quick enough to prevent the paper insulation from burning or

drying out unnecessarily.

After the ferrules have been rubbed smooth and clean, they and the exposed cores must be

treated with hot cable oil (110°C) to remove all dust and moisture. These parts are to be

thoroughly basted with the oil.

The jointer must take care that his hands are dry and clean before the joint is insulated. Also

the insulating tape which is to be used must first be immersed in warm cable oil (110°C) for a

sufficient period to ensure that no moisture is present.

After the individual cores have been installed they must be well basted with hot cable oil and

again after the applicable separator and/or belt insulation tape is applied before the lead joint

sleeve is placed in position.

The lead joint sleeve must be thoroughly cleaned and prepared before it is placed on the cable

and must be kept clean during the whole jointing process. Seal the filling apertures of the

sleeve with tape until the sleeve is ready for compound filling.

The plumbing joints employed to solder the joint sleeve to the cable sheath, must be cooled off

with tallow and the joint sleeve is to be filled with compound while it is still warm. Top up

continuously until the joint is completely filled to compensate for the compound shrinkage.

The outer joint box must be clean and free from corrosion. After it has been placed in position

it must be slightly heated before being filled with compound. Top up until completely full.

As far as cable end boxes are concerned the requirements as set out above are valid where

applicable.

THE NATIONAL INDUSTRIAL PARTICIPATION PROGRAMME

INTRODUCTION

91

The National Industrial Participation (NIP) Programme, which is applicable to all government procurement contracts that have an imported content, became effective on the 1 September 1996. The NIP policy and guidelines were fully endorsed by Cabinet on 30 April 1997. In terms of the Cabinet decision, all state and parastatal purchases / lease contracts (for goods, works and services) entered into after this date, are subject to the NIP requirements. NIP is obligatory and therefore must be complied with. The Industrial Participation Secretariat (IPS) of the Department of Trade and Industry (DTI) is charged with the responsibility of administering the programme.

PILLARS OF THE PROGRAMME

1.1 The NIP obligation is benchmarked on the imported content of the contract. Any contract

having an imported content equal to or exceeding US$ 10 million or other currency equivalent to US$ 10 million will have a NIP obligation. This threshold of US$ 10 million can be reached as follows:

(a) Any single contract with imported content exceeding US$10 million. or (b) Multiple contracts for the same goods, works or services each with

imported content exceeding US$3 million awarded to one seller over a 2 year period which in total exceeds US$10 million. or

(c) A contract with a renewable option clause, where should the option be exercised the total value of the imported content will exceed US$10 million. or

(d) Multiple suppliers of the same goods, works or services under the same contract, where the value of the imported content of each allocation is equal to or exceeds US$ 3 million worth of goods, works or services to the same government institution, which in total over a two (2) year period exceeds US$10 million.

1.2 The NIP obligation applicable to suppliers in respect of sub-paragraphs 1.1 (a) to 1.1 (c) above

will amount to 30 % of the imported content whilst suppliers in respect of paragraph 1.1 (d) shall incur 30% of the total NIP obligation on a pro-rata basis.

1.3 To satisfy the NIP obligation, the DTI would negotiate and conclude agreements such as

investments, joint ventures, sub-contracting, licensee production, export promotion, sourcing arrangements and research and development (R&D) with partners or suppliers.

1.4 A period of seven years has been identified as the time frame within which to discharge the

obligation. REQUIREMENTS OF THE DEPARTMENT OF TRADE AND INDUSTRY

2.1 In order to ensure effective implementation of the programme, successful

92

bidders (contractors) are required to, immediately after the award of a contract that is in excess of R10 million (ten million Rands), submit details of such a contract to the DTI for reporting purposes.

2.2 The purpose for reporting details of contracts in excess of the amount of R10 million (ten million Rands) is to cater for multiple contracts for the same goods, works or services; renewable contracts and multiple suppliers for the same goods, works or services under the same contract as provided for in paragraphs 1.1.(b) to 1.1. (d) above.

BID SUBMISSION AND CONTRACT REPORTING REQUIREMENTS OF BIDDER AND SUCCESSFUL BIDDERS (CONTRACTORS)

3.1 Bidders are required to sign and submit this Standard Bidding Document (SBD 5) together with the bid on the closing date and time.

3.2 In order to accommodate multiple contracts for the same goods, works or services; renewable contracts and multiple suppliers for the same goods, works or services under the same contract as indicated in sub-paragraphs 1.1 (b) to 1.1 (d) above and to enable the DTI in determining the NIP obligation, successful bidders (contractors) are required, immediately after being officially notified about any successful bid with a value in excess of R10 million (ten million Rands), to contact and furnish the DTI with the following information:

• Bid / contract number. • Description of the goods, works or services. • Date on which the contract was accepted. • Name, address and contact details of the government institution. • Value of the contract. • Imported content of the contract, if possible.

3.3 The information required in paragraph 3.2 above must be sent to the Department of Trade and Industry, Private Bag X 84, Pretoria, 0001 for the attention of Mr Elias Malapane within five (5) working days after award of the contract. Mr Malapane may be contacted on telephone (012) 394 1401, facsimile (012) 394 2401 or e-mail at Elias@thedti.gov.za for further details about the programme.

PROCESS TO SATISFY THE NIP OBLIGATION

4.1 Once the successful bidder (contractor) has made contact with and furnished the DTI with the information required, the following steps will be followed:

a. the contractor and the DTI will determine the NIP obligation;

b. the contractor and the DTI will sign the NIP obligation agreement; c. the contractor will submit a performance guarantee to the DTI;

93

d. the contractor will submit a business concept for consideration and approval by the DTI;

e. upon approval of the business concept by the DTI, the contractor will submit detailed business plans outlining the business concepts; f. the contractor will implement the business plans; and

g. the contractor will submit bi-annual progress reports on approved plans to the DTI.

4.2 The NIP obligation agreement is between the DTI and the successful bidder

(contractor) and, therefore, does not involve the purchasing institution.

CERTIFICATE OF INDEPENDENT BID DETERMINATION

1 This Standard Bidding Document (SBD) 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.

102

3 Treasury Regulation 16A9 prescribes that accounting officers and accounting authorities must take all reasonable steps to prevent abuse of the supply chain management system and authorizes accounting officers and accounting authorities to:

a. disregard the bid of any bidder if that bidder, or any of its directors have abused the institution’s supply chain management system and or committed fraud or any other improper conduct in relation to such system.

b. cancel a contract awarded to a supplier of goods and services if the supplier committed any corrupt or fraudulent act during the bidding process or the execution of that contract.

4 This SBD 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 (SBD 9) 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.
