in reference with the below mail and the clarification of Borehole depth if rock formation will be encountered during the execution.
As per NG Consultant recommendation on the matter, we are required to continue the borehole activity until to reach the portion that the said rock formation
is really firmed then we need to ask confirmation from the NG site witnesses to stop the work due to rock condition.
In that case, based on actual accomplishment of the borehole works we can calculate the required additional depth under rock formation to be paid by our side as per mentioned in the PO agreement.
This is as per our Civil Technical Coordinator's recommendation as per site condition in relation with NG Standard.
