21.1 “……. The extra cost, including that occasioned by the subsequent resumption of work, incurred by the Contractor in giving effect to the Owner's instructions under this Article 21.1 shall be borne and paid by the Owner unless such suspension is: a) otherwise provided for in the Contract, or b) necessary by reason of any default on

the part of the Contractor, or for which he is responsible or

c) necessary by reason of abnormal climatic conditions (i.e. climatic conditions which have not been observed in the project area during last 20 years) or the consequences thereof on the Site, or

d) necessary for the proper execution of the Works, or for the safety of the Works or any part thereof.”

The reasons mentioned at sl. no.a), c) & d) of this sub clause are not attributable to Contractor and therefore should be deleted from this clause.

As per prevailing industrial practices, if suspension of work is due to any reason which is not attributable to Contractor, then extra cost towards” idling of resources” is payable to contractor. The provisions of this clause should be similar to JKSPDC’s Lower Kalnai EPC Project.

This tender clause is one sided. If Owner is allowed to suspend the contract for certain reasons, then contractor should be allowed to suspend the contract for breach of contract by Owner. It is requested to kindly include the following clause pertaining to the suspension rights of the contractor also, as mentioned below:

“Suspension by the Contractor:”

The contractor may suspend performance of all or any part of his obligations for such period of time that the Owner is in delay with any of his obligations in connection with the Contract including, amongst others, payment of any due amount. Additionally, the contractor shall have the right to extend such suspension for the time the contractor reasonably may need

to resume his obligations (e.g. for reason of machine utilization, remobilization of workforce, etc.).

As per global practice, Final Acceptance of machine is the event when Field Efficiency & Output Tests are successfully conducted on Turbine and Generator in Hydro Power Plant. After acceptance of Generating Equipment, it is put on Commercial run by Owner. Final Acceptance Certificate is issued to Contractor at this point of time and not after Defect Liability Period as mentioned in this clause. It is requested to kindly modify this clause accordingly.

“ (a) The Owner will make, if so opted for by the Contractor, an interest bearing down payment to him exclusively for the costs of mobilization in respect of the Works in an amount not exceeding 10 (Ten) percent of the Contract Price,which shall be paid in four installments of 30%, 30%, 20% & 20%. Each successive installment shall be released after utilization of previous installment, duly supported by documentary evidence and verified by the Engineer-in-Charge.”

As per standard practice in Hydro Projects if Powerhouse contains multiple generating units of same design then Field Efficiency Tests are conducted on only one unit which is mutually decided by Owner and Contractor. The test results are applicable to all generating units. In case of JKSPDC’s Lower Kalnai EPC Project also the Field Acceptance Tests shall be conducted on one generating unit as selected by Employer. As per the tender provisions under clause no. 7, we understand that Field Efficiency Test is to be conducted on each generating unit. Each test takes around 15 to 20 days’ time for one unit and during this period Unit will not generate the power. To save time and also to save generation loss, all Power Utilities, including NHPC etc. are conducting Efficiency Test on one generating unit only and its results are applied to all other generating units of the Power House for the purpose of LD etc. This clause may please be modified accordingly.

component of the Contract Price respectively. The actual payment of esca-

lation at any stage shall not exceed 20% of cummulative Ex-Works Price or

FOB Price of Plant and Equipment already supplied, as the case may be.

Any escalation at any stage exceeding the aforesaid actual payment in either

the Ex-works Price Component or the FOB Price Component shall be kept

to the credit of the contractor and shall be released as and when the actual

payment of escalation falls below 20% of cummulative Ex-works Price or

FOB of Plant and Equipment already supplied, as the case may be. Any un-

adjusted credit shall however, lapse when the actual cumulative Price Adjust-

ment payments reach the respective ceiling amount of 20% of Ex-works

Price or FOB Price component of the Contract, as the case may be. The
