     item, supplied to any person/organization and such stores have not been offered/sold by me/us to any
     person/organization at a price lower than the price charged under this contract upto the date of this bill.‟


     The bids may be invited either on „firm price basis‟ or on „variable price basis‟, but not on both. Tender
     Inviting Authority may invite any or all the items/components in supply/works/turnkey project tenders on

     The bids may be invited on variable price basis in respect of transmission lines packages, supply of tower
     members and different conductors and major equipments like power and instrument and distribution
     transformers, HV circuit breakers, EHV grade transformer oil or any other materials/packages at the
     discretion of TIA. In such cases Standard Price Variation Formula, based on PV formula published by
     IEEMA/CACMAI or similar recognised sources or adopted by power utilities like NTPC/PGCIL etc shall be
     prepared by TIA for the purpose of price variation of equipments/materials and shall be indicated in the bid
     document.    Bid   document      shall   also   indicate   the   standard   source   of   different   indices   (for

     30 days prior to the last date of submission of price bid or as decided by TIA for this purpose and shall also
     to be indicated in the bid document. The cut off date for different indices in the PV formula for the purpose of
     calculating price variation may be considered as 2 to 4 months ahead of scheduled delivery period or as

     particular date will be applicable.
     Such bids shall be evaluated on the basis of offered price without any loading on account of price variation.
     In case a specific ceiling limit is mentioned in the bid document, payment shall, however, be restricted to the
     actual extent of variation that would take place limited to the ceiling limit. For bids on variable price basis
     without any ceiling limit, payment will also be effected on actuals as per PV formula without any ceiling limit.

     the quantum of CST/VAT, if applicable and F&I Charges embedded in all-inclusive FOR Destination Price.

     by them and to be directly supplied to DVC with ruling rates of taxes and duties which would be reimbursed

     completion period. All taxes and duties applicable on materials/equipment supplied as finished goods to
     DVC through Sub-vendor/Sub-contractor as bought out items are to be included in the price quoted by the
     bidder for such items, which will remain firm throughout the pendency of the contract. This will also cover
     raw material, component, special assembly procured for manufacturing finished goods, material/equipment

     scheduled or actual date of completion unless the contractor is not responsible for the delay and/or it is
     otherwise decided by the authority granting the extension of time. Changes in the tax rate dependant on the
     volume of turn over shall not come under the purview of reimbursement and should be spelt out in the bid
     documents itself.
     For reimbursement of Sales/VAT/Service Tax, self-attested/notarized copy of registration certificate will
     normally be accepted as documentary evidence.
     In case of change of source of supply from Sub Vendor to bidder or Sub Vendor to contractor (if approved
     by DVC), no additional payment shall be made by DVC towards reimbursement of taxes and duties as they
     are deemed to be included in the contract price.
     In the event of change of source of supply from bidder/contractor to Sub Vendor (if approved by DVC), taxes
     and duties will be reimbursed at actual against documentary evidence restricted to the amount of taxes and
     duties as originally payable to the bidder in terms of the contract.

     provisions in the following:
            In case of discrepancy between the original and copies of bid, the original bid will be considered correct.
            If there is a discrepancy between the unit price and the total price, which is obtained by multiplying the unit
             price and quantity of any item, or between sub-total and the total price, the unit or sub-total price shall
             prevail, and the total price shall be corrected accordingly.
            If there is a discrepancy between words and figures, the amount in words will prevail.
            If there is a discrepancy between the quantity specified by DVC in the bidding document and that indicated
             by the bidder in his bid, the former shall be taken to arrive at the computed price on pro-rata basis.
            In case the unit rate of an item is not quoted but the total price is indicated, the same shall be taken to arrive
             at the computed price. The computed price arrived at, as above, shall be considered for the purpose of
             award also.
            If the bidder does not accept the correction of errors as worked out by above methodology, its bid will be

             bidding documents and will be binding on them. Bidders are required to immediately acknowledge receipt of

       Inspection by Purchaser and/or his authorized representative or failure by the Purchaser and/or his
       authorized representative to inspect the material/equipment shall neither relieve the Vendor of any
       responsibility or liability under this Purchase Order/contract in respect of such material/ equipment nor be

       purpose. Alternatively, vendor may arrange transit insurance coverage at his own risk and cost. The
       insurance charge as claimed by the vendor will be payable by DVC on actuals against production of
       documentary evidence.
       In Turnkey Project Contracts, the bidders have to supply materials/ equipments from the vendors approved
       by DVC (which may also include the bidder as manufacturer of the product), which is normally firmed up
       after placement of order. The quoted freight & insurance charges for this purpose are, therefore, irrespective
       of the vendors and geographical locations of their works. The bidder is, therefore, entitled to the fixed freight
       & insurance charges and no documentary evidence in support of the claim may be insisted upon.

       material/equipment is not found in conformity with the specifications, the same shall be rejected by the

       normally within 30 days from the date of Receipt of the material at the Works/Site/consignee‟s end.
         The Vendor on receipt of notification shall arrange removal of the rejected items within 15 days from the
         date of notification at his own cost. In the event the Vendor fails to lift the materials within the said 15 days,
         the Owner without any further notice or information to the vendor, shall be at liberty to dispose of such
         rejected items in any manner as he may think fit. All expenses shall be recoverable from the Vendor.
14.2     In the event, the equipment and materials or any portion thereof are damaged or lost during transit, the
         owner shall give notice to the Supplier/vendor detailing the particulars of such equipments & materials

      and post bid stage.
      For QR related supply items, if any new sub-vendor is proposed by the bidder, it may be approved if it is

      consideration of documents furnished by the sub-vendor and further assessment, if required, may be done
      in the pre-award/post award stage.
               For non-QR items of supply, if new Sub Vendor is proposed by the bidder, it will be obligatory on the
      part of bidder to furnish the details/documents in support of their claim which would be reviewed and

      may be examined keeping in view the qualification requirement applicable for the quantum of job proposed
         to be sub-contracted and other relevant aspects related to the site condition and overall responsibility of the
