THS scoreboard Hi Greg, If you are comfortable with the depth, I would have no issue as it appears to be within an inch or so of the depth requirement in the calculations The plan and calculations that we received and approved show a requirement for a 60" diameter hole For the city to be able to approve the footing and allow work to continue, we would need revised calculations showing that the 50" to 52" (his description to me) would be adequate I do not see any part of the hole in • the photo that appears to meet the 60" minimum diameter shown in the Pole footing calculations I was on -site today and did not see any additional constraint from adjacent paving It is possible that one of the footings may have some abutment, but one footing does not for sure Please let me know if you have any other questions Thank you, Mark VanDomelen Building Official City of Tigard markv@tigard -or gov (503)718 -2448 From: Greg Munsell fmailto:gmunsell©wdyi.comj Sent: Thursday, October 27, 2011 3:00 PM To: Mark VanDomelen ' Subject: THS scoreboard Description from Robert Gray Partners* Hole dug to 13' -4" +/- where water was encountered Belled the bottom as best they could to prevent cave -in placed 'A yard concrete in bottom of each hole for WF base Measurement in photo is next day with depth at 12' -4" to curb (+ yard in bottom) Hole width varies from 4' -3" min to 4' -5" With the actual width, hole depth requirement is right at excavated depth I would not think there was much to gain by drilling deeper into the saturated layer Also, there is some constraint with the adjacent paving so I am comfortable with what they have done Let me know if you need further clarifications Greg G Munsell WDY Structural - Civil Engineers 6443 SW Beaverton - Hillsdale, Suite 210 Portland, Oregon 97221 ph 503 203 8111 fax 503 203 8122 www wdyi corn Confidentiality Note The information contained in this message and any attachments, may contain confidential and/or privileged material It is intended solely for the person(s) or entity to which it is addressed Any review, retransmission, dissemination, or taking of any action in reliance upon this information by persons or entities other than the intended recipient(s) is prohibited If you received this in error, please contact the sender and delete the material from any computer DISCLAIMER E -mails sent or received by City of Tigard employees are subject to public record laws If requested, e-mail may be disclosed to another party unless exempt from disclosure under Oregon Public Records Law E -mails are retained by the City of Tigard in compliance with the Oregon Administrative Rules' City General Records Retention Schedule " • 2
