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"

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 | 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 | 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.
