Dear Hans,
Mr. Niu called me, he said, now, the foundation is finished from column 2/15 to 1/13.
Now, they are preparing the civil work of column 1/13 to 1/10. But they found column 1/10 is in same line with the 3 existing leaching tanks.
That means, column 1/10 will not be started before the existing leaching tanks being removed.
My suggestion is we can stop in column 11 and keep the extension possibility. Pls. feed back your comments.
