[Dsg-rich] Questions and confirmations regarding RICH assembly anchoring

[Dario Orecchini]

*Hi Tyler,*
*following the required information.*

1.      In October 2016 (email below in blue), Sandro noted that the
assembly structure would need 3/4 inch Hilti bolt anchors. Have the Hilti
bolts been included in the crates that arrived at JLab in January?

      *No, they aren’t included in the crates.*



2.      Could you confirm that 3/4 inch diameter bolts will be used to
anchor the assembly structure?

*Yes, we confirm the ¾ inch diamenter bolts. *

*The anchor bolts system details are shown in the document: SMC
TA-STR-001.pdf. *

*I send it in attachement.*

*It consist of two components:*

-          *1) DROP-IN ANCHOR HDI ¾” *https://www.us.hilti.com/
anchor-systems/flush-anchors/336429,

-          *2) THREADED ROD 8” in lenght (Steel grade A).*



*In addition I send you the file: “Anchoring Template Layout In EEL124_Top
View”with:*

-          * the position of the drilling template;*

-          *The view of the drilling template assembled;*

-          *The typical section of the anchoring system.*



3.      Could the drilling to anchor the assembly structure occur prior to
INFN collaborator arrival at JLab? DSG could assemble the drilling template
and arrange the anchor holes drilling for the week of February 27 as the
blind drilling permit is valid starting February 27, 2017.

*Yes, you can procede about the realization of the drilling.*



4.      In October 2016, a CAD model containing the EEL124 layout for RICH
assembly was shared with the DSG. Attached is a top view of the model with
dimensions measured in inches. Could you confirm that this is the correct
layout for RICH assembly?

*To avoid any misunderstanding see* *the file: “Anchoring Template Layout
In EEL124_Top View*



*As you prefer, we can arrange a meeting (Skype or Blue Jeans) to clarify
any doubts. *


*Best regards*

*Dario & Sandro*
