INTRODUCTION
1. COMPANY PROFILE
1.1. Incorporation and Mandate
Kenya Pipeline Company (KPC) Limited was incorporated on 6th September 1973 under the Companies
Act (CAP 486) and started commercial operations in 1978. The Company is 100 percent owned by the
Government and complies with the provisions of the State Corporations Act (Cap 446) of 1986. The
company operations are also governed by relevant legislations and regulations such as; the Finance Act,
the Public Procurement Regulations, amongst others.
1.2. Pipeline System
The pipeline system currently consists of 450 km of Line-1 running from the port of Mombasa to
Nairobi, 325 km of Line-4 from Nairobi to Eldoret, 325 km of Line-2 also from Nairobi to Eldoret, 121
km of Line-3 from Sinendet to Kisumu, and 121 km of Line-6 from Sinendet to Kisumu making a total
of 1342 km. Presently, a 450 km of Line-5 from Mombasa to Nairobi is under construction.
2. JUSTIFICATION
Kenya Pipeline Company Pumping Stations 2 and 4 (PS02, Samburu, PS04, Manyani, and PS06,
Makindu) are located along Line 1, and were commissioned in 2008 as a capacity enhancement project
for the Line one, alongside PS06 (Makindu) and Konza (PS08). These Stations are white petroleum
products’ pumping stations comprising three mainline pumps per station. Each of the pumps is driven by
medium voltage induction motors of about 2,200 Horsepower each, operating at 6600 Volts. The
Stations are supplied with electrical power from the Rabai-Juja 132KV Transmission Line, stepped
down to the required 6600 Volts by 132/6.6KV 5MVA Step-down power transformers. Each of the
pumps is driven by medium voltage induction motors of about 2,145 Horsepower each, operating at
3300 Volts.
Consequently, at these Stations, there are 132KV, and 6.6KV, control panels and switchboards for
which 110 Volts DC control power is supplied by Rectifier/Chargers and associated Battery Banks.
The 110VDC Rectifier Chargers installed PS02, PS04, and PS06 Stations at commissioning in 2008
have been failing regularly, frequently interrupting availability of these Stations which are critical to
maintaining Line 1 flowrates at desired levels. These rectifier chargers were of a 2+1 design comprising
three 10A chargers. Presently, only one charger is available per Station, the others having failed at
various points in the past. Compounding the problem is the fact that spares have been difficult to find,
the chargers being ex-China.
This tender for ‘SUPPLY, INSTALLATION, AND COMMISSIONING OF 110VDC RECTIFIER
CHARGERS FOR PS02 (SAMBURU), PS04 (MANYANI), AND PS06 (MAKINDU))’ therefore is
to procure replacement for these 110VDC rectifier chargers to ensure availability of reliable control
voltage for the Stations.

result in the rejection of the tenderer’s tender.
22 Clarification Tenders
22.1 To assist in the examination, evaluation and comparison of tenders, the Employer may
ask tenderers individually for clarification of their tenders, including breakdown of unit
prices. The request for clarification and the response shall be in writing or by cable,
facsimile or telex, but no change in the price or substance of the tender shall be sought,
offered or permitted except as required to confirm the correction of arithmetical errors
discovered by the employer during the evaluation of the tenders in accordance with
clause 24.
Page 17 of 78
22.2 No Tenderer shall contact the Employer on any matter relating to his tender from the time
of the tender opening to the time the Contract is awarded. If the tenderer wishes to bring
additional information to the notice of the Employer, he shall do so in writing.
23 Determination of Responsiveness
23.1 Prior to the detailed evaluation of tenders, the Employer will determine whether each
tender is substantially responsive to the requirements of the tender documents.
23.2 For the purpose of this clause, a substantially responsive tender is one which conforms to
all the terms, conditions and specifications of the tender documents without material
deviation or reservation. A material deviation or reservation is one which affects in any
substantial way the scope, quality, completion timing or administration of the Works to
be undertaken by the tenderer under the Contract, or which limits in any substantial way,
inconsistent with the tender documents, the Employer’s rights or the tenderers obligations
under the Contract and the rectification of which would affect unfairly the competitive
position of other tenderers who have presented substantially responsive tenders.
23.3 Each price or unit rate inserted in the Bills of Quantities shall be a realistic estimate of the
cost of completing the works described under the particular item including allowance for
overheads, profits and the like. Should a tender be seriously unbalanced in relation to the
Employer’s estimate of the works to be performed under any item or groups of items, the
tender shall be deemed not responsive.
23.4 A tender determined to be not substantially responsive will be rejected by the Employer
and may not subsequently be made responsive by the tenderer by correction of the non-
conforming deviation or reservation.
24 Correction of Errors
(a) There shall be no correction of arithmetic errors.
(b) The completed Bills of Quantities shall match KPC requirements (BOQ). Any
amendments to the KPC BOQ shall be considered non-responsive and result in
disqualification of the bid.
25 Conversion to Single Currency
25.1 For compensation of tenders, the tender price shall first be broken down into the
respective amounts payable in various currencies by using the selling rate or rates of the
Central Bank of Kenya ruling on the date twenty one (21) days before the final date for
the submission of tenders.
25.2 The Employer will convert the amounts in various currencies in which the tender is
payable (excluding provisional sums but including Dayworks where priced
competitively) to Kenya Shillings at the selling rates stated in clause 25.1.
Page 18 of 78
26 Evaluation and Comparison of Tenders
26.1 The Employer will evaluate only tenders determined to be substantially responsive to the
requirements of the tender documents in accordance with clause 23.
26.2 The Employer reserves the right to accept any variation, deviation or alternative offer.
Variations, deviations, alternative offers and other factors which are in excess of the
requirements of the tender documents or otherwise result in the accrual of unsolicited
benefits to the Employer, shall not be taken into account in tender evaluation.
26.3 Price adjustment provisions in the Conditions of Contract applied over the period of
execution of the Contract shall not be taken into account in tender evaluation.
26.4 If the lowest evaluated tender is seriously unbalanced or front loaded in relation to the
Employer’s estimate of the items of work to be performed under the Contract, the
Employer may require the tenderer to produce detailed price analyses for any or all items
of the Bills of Quantities, to demonstrate the relationship between those prices, proposed
construction methods and schedules. After evaluation of the price analyses, the
Employer may require that the amount of the Performance Security set forth in clause 29
be increased at the expense of the successful tenderer to a level sufficient to protect the
Employer against financial loss in the event of subsequent default of the successful
tenderer under the Contract.
26.5 Firms incorporated in Kenya where indigenous Kenyans own 51% or more of the share
capital shall be allowed a 20% preferential bias provided that they do not sub-contract
work valued at more than 50% of the Contract Price excluding Provisional Sums to a
non-indigenous sub-contractor.
26.6 The tender evaluation committee shall evaluate the tender within 30 days of the validity
period from the date of opening the tender.
26.7 Persons not officially involved in the evaluation of tender shall not attempt in any way to
influence the evaluation.
27. Preference where allowed in the evaluation of tenders shall not exceed 20%
AWARD OF CONTRACT
28 Award criteria
28.1 Subject to clause 27.2, the Employer will award the Contract to the tenderer whose tender is
determined to be substantially responsive to the tender documents and who has offered the
lowest evaluated tender price subject to possessing the capability and resources to effectively

SECTION VIII: SPECIFICATIONS
Notes for preparing Specifications
1.0 Specifications must be drafted to present a clear and precise statement of the required standards
of materials, and workmanship for tenderers to respond realistically and competitively to the
requirements of Kenya Pipeline Company Limited and ensure responsiveness of tenders. The
Specifications should require that all materials, plant, and other supplies to be incorporated in the Works
be new, unused, of the most recent or current models, and incorporating all recent improvements in
design and materials unless provided otherwise in the Contract. Where the Contractor is responsible for
the design of any part of the permanent Works, the extent of his obligations must be stated.
2.0 Specifications from previous similar projects are useful and it may not be necessary to re- write
specifications for every works contract for universal application.
3.0 There are onsiderable advantages in standardizing General Specifications for repetitive Works
in recognized public sectors, such as highways urban housing, irrigation and water supply. The General
Specifications should cover all classes of workmanship, materials and equipment commonly involved in
constructions, although not necessarily to be used in a particular works contract. Deletions or addenda
should then adapt the General Specifications to the particular Works.
4.0 Care must be taken in drafting Specifications to ensure they are not restrictive. In the
specifications of standards for materials, plant and workmanship, existing Kenya Standards should be
used as much as possible, otherwise recognized international standards be used.
5.0 Kenya Pipeline Company Limited should decide whether technical solutions to specified parts of
the Works are to be permitted. Alternatives are appropriate in cases where obvious (and potentially less
costly) alternatives are possible to the technical solutions indicated in tender documents for certain
elements of the Works, taking into consideration the comparative specialized advantage of potential
tenderers.
Kenya Pipeline Company Limited should provide a description of the selected parts of the works with
appropriate reference to Drawings, Specifications, Bills of Quantities, and Design or Performance
criteria, stating that the alternative solutions shall be at least structurally and functionally equivalent to
the basic design parameters and specifications.
Such alternative solutions shall be accompanied by all information necessary for a complete evaluation
by Kenya Pipeline Company Limited, including drawings, design calculations, technical specifications,
breakdown of prices, proposed construction methodology, and other relevant details. Technical
alternatives permitted in this manner shall be considered by Kenya Pipeline Company Limited each on
its own merits and independently of whether the tenderer has priced the item as described in Kenya
Pipeline Company Limited’s design included with the tender documents.
