1. INTRODUCTION OF PROJECT

The North Karanpura Coalfield is the western most and second largest (1230 km2) coal basin of the Hazaribagh, Palamu and Chatra districts of Jharkhand, India. It is situated about 60 km northwest of Ranchi and 20km SW of Hazaribagh. North Karanpura CBM Block (NK-CBM-2001/1) is a part of the North Karanpura Coal field covering an area of 340 sq. Kms. Subsequent to relinquishment of 68.5 sq.km area after initial assessment, 271.5 sq.km are left for CBM exploration and development. Presently, approx. 49 sq. kms area has been carved out for initial development with a provision for further development in future. The North Karanpura block area is sparsely populated with a forest cover of over 20% of the area. Active coal mines are few in this coalfield and all are located outside the block area. The block area is approachable from Ranchi on the southern side and Hazaribagh on the northern side by all-weather metaled road, which in turn connects to nearby towns by fair-weathered metaled roads. The nearest domestic airport is located at Ranchi. Ramgarh is the nearest town with railway station.

4.2.1. Delay in Mobilisation and Liquidated Damages:

i. CONTRACTOR (successful bidder) shall mobilize and deploy the required

manpower and complete CBM gas Compressor and Dehydration unit, so as to commence the services at the specified site within a maximum of 120 days from the date of email order / LOA.

ii. If the CONTRACTOR (successful bidder) fails to mobilize and deploy the

required manpower /equipment and / or fails to commence the services within the period specified in sub clause (i) above, PEPL shall have, without prejudice to any other right or remedy in law or contract including sub clause (iii) below, the right to terminate the contract.

iii. If the CONTRACTOR is unable to mobilize / deploy and commence the services

within the period specified in sub clause (i) above, it may request PEPL for extension of the time with unconditionally agreeing for levy and recovery of LD. Upon receipt of such a request, PEPL may at its discretion, extend the period of mobilization and shall recover from the Contractor, as an ascertained and agreed Liquidated Damages, a sum of equivalent to ½% of the total contract value, for each week of delay on prorata basis , subject to a maximum of 10% of the total Contract value.

iv. Delay in mobilization of additional compressor (10,000 SCMD): If the

CONTRACTOR is unable to mobilize / deploy and commence of additional compressor within the period 120 days, it may request PEPL for extension of the time with unconditionally agreeing for levy and recovery of LD. Upon receipt of such a request, PEPL may at its discretion, extend the period of mobilization of additional compressor and shall recover from the Contractor, as an ascertained and agreed Liquidated Damages, a sum of equivalent to ½ % of the calculated total contract value for additional compressor, for each week of delay on prorata basis, subject to a maximum of 10% of the total Contract value for additional Compressor.

Example: If Contractor quotes total contract value of compression and dehydration charges of 20,000 SCMD gas as ‘X’. After award of Contract, PEPL give callout for mobilization of additional compressor 10,000 SCMD after 14 months. However, contractor delays mobilization of equipment by 10 days for initial mobilization and 12 days for subsequent (additional mobilization). The procedure for calculating the LD for initial mobilization and additional mobilization will be as follows:


16

Calculation of LD for Initial Mobilization Total Contract Value– X Contract Period – 5 years Delay in Mobilization – 10 days LD on Mobilization = X * ½% * 10 / 7 Calculation of LD for additional Mobilization Total Contract Value– X Contract Period – 5 years Delay in Mobilization – 12 days Call out given after 14 months LD on Mobilization = (Total contract period (yrs) – time after callout for mobilization of additional compression given/12) * X * ½% * 12 / 7 *compression capacity of callout/compression capacity of as per contract LD on Mobilization = (5 – 14/12) * X * ½% * 12 / 7 * 10000 / 20000

v. Liquidated Damages for Delay in Demobilization: In case Contractor fails to demobilize, or delays in demobilization of Gas compressor package and dehydration system beyond 30 days’ time permitted for the same, liquidated damages will be charged @ Rs. 10,000 per day, subject to a maximum 10% of annualized total Contract value.
