Ebasco transits " Preliminary" CTH drawings (Redlines) to Impe11 for analysis. During the design verification processi Impe11 may
~
note deviations that may require drawing modification. -
Informational exhanges between Impell and Ebasco are made which l
may rwsult in re-issuance of the Redline CTH drasing.
2.
Ebasco site transmits Redline drawings to Ebasco drafting (AE-CAD) concurrent with their transeittal to Impell. Periodic issues of -
the NF CAD drawings are transmitted to TUG (X>-DCC and Impe11.
These drawings incorporate the As-built data recorded on the Redline drarings.
They are issued to TUGOD-DCC for TUG (X>-QC Verification.
Additions and/or clarifications may be made by Impell.
3.
Ebasco has generated SPAN drawings to assist in their Walkdown verification of the CTH (Redlines). Those SPAN drawing pertinent to Impe11 scope have been transmitted; Additions and/or clarifications may be made by Impe11.

luGCX)-QC may generate, as a result of their inspection of a CTH, and MINSAT* report. These reports are reviewed by Ebasco. They O
are responsible to determine if the report is a result of r drafting error or if it is a noreconforming condition (N(R). The "UNSAT* report may be resolved by a reyiston of the JG-CAD, ~1f it is a drafting error.
If the report is an NCR and it is in our scope, it is transmitted to Impe11 for engineering evaluation.
i 5.
Interdtsciplinary interf ace may be required.. For example, a CTH may partially be supported f rom a pipe support. When a condition such as this occurs the pipe support responsible ~ ongineer will generate a Request For Information (RFI) requesting the loading that the CTH contributes to the pipe support.
If the CTH is within Impell's work scope, we are responsible to respond to the RFI. The response is transeitted through Ebasco to the responsible engineering discipline. _

1.0 IK1RG1lCTION The Ommanche Peak Steam Electric Station specif1 cation EI-20 for installation of Hilti drilled-in bolts (Reference 1) allows the removal of an existing Hilti anchor by core drillfag a hole around the existing anchor and then installing the next larger anchor in the core drilled hol e.
The issue develope in that Hilti does not guarantee the bolt allowables when the holes were drilled with anything other than Hilti masonry carbide bits. There is a concern that due to the difference in hole contour and size es Hilti bolt may not develop the full capacity.
Our rwiew of the installation procedure indicates that Hilti bolts installed in core drilled holes in accordance with ee Reference 1 will be able to develop the required capacities.
I 2.0 Standard M11tf Installation Procedure The Hilti installation procedure calls for a hole of es same nominal diameter as the bolt to be drilled with a Hilti masonry carbide bit.
hole eat is formed with this bit is irregular in shape but sized so as to O
provide a firm fit for the bolt.
The Hilti bolt is then driven into the hole far enough to allow at least six threads to be below the fixture.
Hilti bolts are then tightened using a turn-of-thenut meeod. By turning the nut 3 to 4 revolutions a load slightly above the working load i
allowable is achtwed.
The anchorage is locked in place by the wedges i
being forced against the side of the bolt hole as the tappered cone at the l
and of the bolt is drarn up.
1 3.0 1trani STANDARD INSTALLATION Rt0GI111E FOR HILTI B(LTS l
l The 1DGoo procedure calls for the drilling of holes using Hilti carbide bits in compliance with Hilti requirements. The bolt is then driven into the hole and torquod to specified torque level. This torque value is l
based on tests conducted by Hilti at the 1DG00 $1to.
The TUGCo installation procedure limits the amount that the bolt may be pulled out of the hate during torquing to one nut thickness.
One nut thickness is slipitly more een the 3-4 turns recommended by Hilti. However, there l
appears,to be sufffciont bolt end cono to allou a one nut pull out v12out
=
slipping past the wedges.

,8 4.0 luGiB HILE_MPLAMENT Rt0Et0E The TUGoo installation specification for Hilti bolts allows for the replacement of an existing Hilti bolt using a diamond core bit of the same nominal outstde dimeter as the replacement expansion bolt. Once the now hole has been made the bolt is then installed in accordance with a regular TUGOs procedure.
It should be noted that a core drilled hole is generally round in shape and may be s11ptly larger than that drilled with a Hilti carb1de masonry bit. The insta11atton of the rep 1acoment bolt is then done with the same procedure as for the original bolts. This means that the torque limits specified in the TUGoo procedure must be achtwed and the increase in bolt predoction must be limited to the one nut thickness value specified in the installation specification for bolts installed in carbide btt drilled holes.
5.0 CONCLUSION
The Hilti anchors are essentially a pro stressed connection in that the torquing dono during installation pre loads the bolt and assures that th working load capacity has been achtwed.
When a bolt is installed in a dimond core drilled hole the hole size may deviate free that required t achieve maxian capacity.
However, the requirment for the same bolt O-torque in the core drill hole as in the carbide bit det11ed hole should assure that the required preload has been achtwed.
The limitation on bolt pullout during setting must still be maintained for the dissond core drilled hole installatton.
Based on the torque and pullout limits it can be concluded that the bolt will have the required preload and capacity and that the wedges will have the same amont of margin against slip through as the bolts in the carbide btt drilled hole. The requirement to achtwo the mintam torque level and the limitation of bolt pullout during setting is considered adequate to assure that the Hilti expansion anchor will adieve an acceptable capacity in the diamond core drilled hole.
