Wapda
The Water and Power Development Authority (WAPDA) is a government-owned public
utility maintaining power and water in Pakistan, although it does not manage thermal power.
WAPDA includes Tarbela and Mangla dams among its resources. Its headquarters are in Lahore.
WAPDA was established in February 1959 to unify the maintenance of infrastructure previously
overseen by provincial agencies. Its Chairmen included outstanding civil servants like Ghulam
Ishaq Khan, Ghulam Faruque Khan and Aftab Ghulam Nabi Kazi who were
subsequently President of Pakistan, Minister for Commerce and Economic Adviser, respectively.
In October 2007, thermal power management was split into the newly formed Pakistan Electric
Power Company (PEPCO)
Initially it has two chief engineers
 East chief engineer
 West chief engineer.
Members of Wapda
Wapda is consisted on four members
 Chairman Wapda (head)
 MD water
 MD power
 MD finance
When these four members have a meeting, it is called "authority meeting"

 Price control
Area Electricity Board in 1982, in which these distribution companies were named base on the
areas, like LESCO was known at that time as “Lahore Electricity Area Board”
Company Act
In 1994, according to Company Act, distribution companies were formed.
The ultimate goal was to privatize all these distribution companies

Material Procurement
Definition of Procurement
The act of obtaining or buying goods and services.
The process includes preparation and processing of a demand as well as the
end receipt and approval of payment.
Steps in Procurement
It often involves:
(1) purchase planning,
(2) standards determination,
(3) specifications development,
(4) supplier research and selection,
(5) value analysis,
(6) financing,
(7) price negotiation,
(8) making the purchase,
(9) supply contract administration,
(10) inventory control and stores, and
(11) disposals and other related functions.
The process of procurement is often part of a company's strategy because the ability to purchase
certain materials will determine if operations will continue. A business will not be able to survive
if its price of procurement is more than the profit it makes on selling the actual product.

Types of Bidding
There are many types of Bidding, but two of them are mostly common
1. Single stage single envelop Bidding
2. Single stage Double envelop Bidding
3. Two stage bidding
Single Stage one-envelope bidding procedure:
In the Single Stage one-envelope bidding procedure, bidders submit one envelope
containing the price proposal and the technical proposal. The envelope is opened in the
presence of bidders’ representatives who choose to attend. The total amount of each bid
and any alternative bid, and other relevant details are read out and recorded. The bid is
evaluated and the award of contract is made to the lowest evaluated substantially
responsive bidder.
The Single Stage one-envelope bidding procedure should be utilized for contracts where
the civil works content is very high and the design works are related to conventional type
of works where there is not likely to be wide variance in the prices such as for roads,
pipelines, industrial buildings and power transmission line projects. This option assumes
prequalification.
Bidding Example
Bidder must submit Earnest Money mentioned above along with the bid in the form of Pay
Order/Demand Draft of the total bid value, not less than 2%, otherwise bid may be rejected.
- Bidders are requested to submit all relevant documents with the bid including acknowledgement
conforming to the terms and conditions of the contract.
- Those bidders who conform to technical specifications & requirements including terms & conditions of
the contract shall be eligible for award of contract.
- Information given, if found to be incomplete/ false at any stage, will result in immediate rejection of
bid.

12. 12 | P a g e
- The bidder may require to furnish proof regarding past experience of similar works and financial
strength to accomplished desired job(s), where adequacy of the bidder is not found to be appropriate, shall
be rejected.
- PSO may ask for any further information and details at any time during evaluation period if required.
- All queries for the subject tender (if any) should be posted on procurement@psopk.com at least 05
working days prior to bid opening date.
- PSO reserve the right to reject all bids according to PPRA rule 33.
- This advertisement is for one time procurement of the Captioned Goods / Services / Work only, which
does not qualify for other similar future jobs in PSO. Sealed bid should be dropped in Tender Box marked
“PROCUREMENT” at Ground Floor, PSO House, Khayaban-e- Iqbal, Clifton, Karachi or mailed to
reach this address before aforementioned due date and time.
- Bids will be opened in the presence of bidders or their authorised representative having valid authority
letter from their respective company.
Single Stage two-envelope bidding procedure:
The Single Stage two-envelope bidding procedure should be used in situations similar to the Single-
Stage one envelope procedure except that in this case the design concept and skill required
is more advanced although there is not likely to be problems in the evaluation of alternative
proposals for machinery or equipment. The two envelope procedure is preferred so as not
to let the price influence the technical evaluation. This option assumes prequalification to
ensure that only experienced and financially capable firms will submit bids for civil works
Design-Build contracts, and contracts for the fabrication of expensive and technically
complex items.
Where the Public Body considers that the project under reference is not complex
and is below the threshold requiring pre-qualification, it may opt to use the bidding documents for the single
stage without prequalification (Circular N0. 9 of 2012). In such cases the following amendments have to
brought to the documents:

13. 13 | P a g e
Submit proposals regarding work methods, scheduling and resourcing which shall be, provided in sufficient
detail to confirm the bidders’ capability to complete the works in accordance with the Employer’s
Requirements, the specifications and the time for completion.
Two-Stage bidding procedure:
For the Two Stage Bidding the following procedure shall apply:
(a) The first stage bid will consist of a technical bid only, without any reference to
prices, and a list of any deviations to the technical and commercial conditions set
forth in the bidding documents or any alternative technical solutions a Bidder
wishes to offer, and a justification therefore, always provided that such deviations
or alternative solutions do not change the basic objectives of the project. Following
evaluation of the first stage bids, the Employer will invite each Bidder who meets
the minimum acceptable qualification criteria and who has submitted a technically
responsive first stage bid to a clarification meeting, during which the Bidder’s bid
will be reviewed and all required amendments, additions, deletions and other
adjustments will be noted and recorded. Only those bidders submitting a
technically responsive and acceptable first stage bid will be invited to submit a
second stage bid.
(b) The second stage bid will consist of:
(i) an updated technical bid incorporating all changes required by the Employer
or as necessary to reflect any amendment to the bidding documents issued
subsequent to submission of the first stage bid, and
(ii) The commercial bid.
The Two-Stage bidding procedure should be utilized for projects where alternative
technical proposals are possible such as for certain types of machinery or equipment or for
certain types of manufacturing plants. As only experienced bidders are expected to submit
bids for such projects and as prequalification is not generally required for equipment and
machinery, post-qualification of bidders is included in the bidding documents. In the
detailed evaluation of the bidders' technical proposals, the qualifications of the bidders in
respect of experience and financial capacity are evaluated in the first instance and bidders
who do not meet the post-qualification criteria are not considered further.
