1. INVITATION TO TENDER

1.1 Background

The SCADA system plays a major role in enabling the organization to meet the obligatory

requirements for quality of service and supply according to the national standards SZNS026 and

SZNS028, as regulated by SERA, through remote monitoring and controlling of the power

network. To achieve this function remote terminal units (RTUs) are installed at the remote

substations for automation. A significant number of these RTUs is the now obsolete IST Talus

RTU type, installed in year 1998 to 2000.

The Eswatini Electricity Company (EEC) intends to replace obsolete Talus type Remote

Terminal Units (RTUs) at Bigbend, Mpisi and Mpaka substations. A RTU is an equipment

installed at the substation end to enable remote monitoring and control of that site. The project is

done in phases depending on budget availability and the decommissioned system components are

used as spares for the RTUs that are still running in the power network.

1.2 Objective

The primary objective of this project is to improve the reliability of the SCADA system in the

above mentioned substations by providing more reliable RTU systems whilst at the same time

optimizing costs by using the replaced components as spares to the remaining Talus RTUs.

1.3 Scope of Work

evidence of their presence.


of 19

Envelopes marked “Withdrawal” shall be opened first and the name of the Tenderer shall be read

be opened.

The Tenderer’s names, the Tender Prices including any alternative Tender Price or deviation any

any such other details as the Employer may consider appropriate, will be announced by the

Employer at the opening.

Subsequently, all envelopes marked “Modification” shall be opened and the submissions therein

No Tender shall be rejected at Tender opening except for late Tenders

The Employer shall prepare minutes of the Tender opening, including the information disclosed

to those present.

During the Tender evaluation, the Employer may, at its discretion, ask the Tenderer for

clarification of its Tender.

The request for clarification and the response shall be in writing and no change in the price or

substance of the Tender shall be sought, offered or permitted.

Preliminary Examination of Tenders

The Employer will examine the Tenders to determine whether they are complete, whether any

computational errors have been made, whether required sureties have been furnished, whether

the documents have been properly signed, and whether the Tenders are generally in order.

Arithmetic errors will be rectified on the following basis. If there is a discrepancy between the

unit price and the total price, which is obtained by multiplying the unit price and quantity, or

between subtotals and the total price, the unit or subtotal price shall prevail, and the total price

shall be corrected. If there is a discrepancy between words and figures the amount in words will

prevail. If the Tenderer does not accept the correction of errors its Tender will be rejected.

Prior to the detailed evaluation, the Employer will determine whether each Tender is of

acceptable quality, is complete and substantially responsive to the Tender Documents. For

purposes of this determination, a substantially responsive Tender is one that conforms to all

terms, conditions and specifications of the bidding documents without material deviations and

objections, conditionality or reservations. A material deviation, objection, conditionality or

reservation is one (i) that affects in any substantial way the scope, quality or performance of the

contract; (ii) that limits in any substantial way, inconsistent with the Tender Documents, the

Employer’s rights or successful Tenderer’s obligations under the contract; or (iii) whose

rectification would unfairly affect the competitive position of other Tenderers who are presenting

substantially responsive.


of 19

If a Tender is not substantially responsive, it will be rejected by the Employer, and may not

subsequently be made responsive by the Tenderer by correction of the non-conformity. The

Employer’s determination of a Tender’s responsiveness is based on the contents of the Tender

itself without recourse to extrinsic evidence.

Contacting the Employer

From the time of the tender opening to the time of Contract award, if any Tenderer wishes to

contact the employer on any matter related to its Tender, it should do so in writing.

Any effort by a Tenderer to influence the Employer in the Employer’s Tender evaluation, Tender

comparison or Contract award decisions may result in rejection of the Tenderer’s Tender.

2.1.12 Award of Contract

Award Criteria

The Employer may award the contract to the Tenderer whose Tender has been determined to be

substantially responsive and provided that the Tenderer is determined to be qualified to perform

the Contract satisfactorily. The Employer is not bound to accept the lowest Tender or any at all

and no reasons will be given for non-acceptance of Tender.

Employer’s Right to Accept Any Tender and to Reject Any or All Tenders

The Employer reserves the right to accept or reject any Tender, and to annul the Tendering

process and reject all Tenders at any time prior to award of Contract, without thereby incurring

any liability to the affected Tenderer or Tenderers or any obligation to inform the affected

Tenderer or Tenderers of the grounds for the Employer’s action.

Employer’s Right to Vary Quantities at Time of Award

The Employer reserves the right at the time of award of Contract to increase or decrease the

quantities of goods and services up to 25% of the Total Tender Price without any change in unit

prices, Preliminary and General cost, or other terms and conditions.

Pre-Award Negotiations

Prior to the expiry of the period of Tender Validity, the Employer will invite the successful

Tenderer to his office for Contract negotiations.

The successful conclusion of the Contract Negotiations will constitute the formation of the

Contract.

The Employer shall prepare the Minutes of Contract Negotiations which shall form part of the

Contract.

Upon the successful Tenderer’s furnishing of a Performance security the Employer will promptly

notify each unsuccessful Tenderer and will discharge its Tender security.
