End of March 2015 start civil work. It have been impacting to our scheduling construction work, such as civil foundation, piping and metering installation, E & I installation, including commissioning metering skid. Anyhow if the nitrogen gas couldn't supply on time your required as MOM A1303-PTTME-VCX Linde-N-0002==>Item no. 1.9 ==>VCX will require nitrogen at the end of April 2015, that didn't impact to your schedule commissioning period, could you please let we know the target or expected the Nitrogen supply date to us? Anyway, I would like to propose to extension from enf of March to 20 June 2015 to completed construction work and supply Nitrogen to Vencorex plant. Anyhow if your have any comment or concern please advise and discussion krub. Thank you.
