Deiadra We will confirm that the newly established control ties with the original points that we were able to find. There was no elevation given for the new control points so we will have to run elevations to them from the old points. We should know by Wednesday morning if the newly established control ties into the old control points or not. After that we would be able to proceed. Todd Henson Sr. Project Manager Austin Bridge & Road 214-681-2128 From: Chris Yarbrough Sent: Friday, July 16, 2010 11:47 AM To: Todd Henson; Jeffrey Gray Subject: RE: Survey Control Todd, I did talk to Bruce this morning about the control he sent on 7/9/10 titled “WO4568, COORDS.PDF”. I informed him that we typically do not use property corners to establish control. His original email (on the 9th) did not specify that his firm had recently established that control or that they were not property corners from the original plat (which is what the control points are illustrated on). He explained (today) that those two points were established on the 9th. I then told him that we would try to verify that those two points match the other control specified in the plans and the existing conditions of the job site (horizontal and vertical). We will not lay out anything until this is done. Jeff Gray will be coordinating the survey portion of the project from this point on. I have attached the file “WO4568, COORDS.PDF” for clarity.
