How are you going? I just like to know if you could offer the update site contour line to us for calculation. After site visit we found there is some difference between the former contour map you offered 20160622, you know the construction has been done, the site at some point may be lower than following and also in the future there may some difference from now.
If you think there is no need for update we will follow the contour line sent at 20160622 for calculation.
