The log shall then be presented to QC for material verification and signature.
Welding material shall be controlled in accordance with CPM-6.98.
2.1.2 Material Identification Prior to cutting, the heat or identification (MIC, code, etc.)
numbe'r shall be transferred by mechanical marking, and this mark-ing shall remain distinguishable throughout the fabrication pro-cess. Additionally, the support assembly shall be mechanically identified with the hanger mark number which shall remain dis-tinguishable throughout the installation.
NOTE:
Heat numbers must be recorded for Class I support materials.
3.0 PROCEDURE 3.1 HANGER PACKAGES 3.1.1 Fabrication / installation o.f component supports will be in accord-ance with the hanger package for supports. The package will consist of BRH drawing, Material Identification Log (MIL), Weld Data Card (WDC) and Weld Filler Material Log (WFML) for each hanger.

Where the design shows 0" on one side and 1/16" on the other side, 0" must be maintained while 1/16" 1/32" is required on the other side.
3.
Where the design shows 0" on one side w/1/16" on the other side, if 0" cannot be maintained on the side shown, the situation will have to be investi-gated and resloved by Site Engineering.

9/3/80 ATTACHMENT 1 BASE PLATES INSTALLATION GUIDELINES SCOPE Construction guidelines for the installation of pipe support base plates and concrete anchor bolts which deviate from the original design.
GENERAL These guidelines apply only to pipe support base plates attached to structure with four concrete anchor bolts.
Any of the following conditions require engineering evaluation, on a case-by-case basis, prior to design deviation in excess of construction tolerances:
A.
Base plates attached with more than or less than four con-crete anchors.
B.
Base plates attached with Ih" Super Hilti anchor bolts (all lengthes.)
C..
Core drilled base plate anchors.
D.
Base plates ik" or greater in thickness.
E.
All violations of minimum Hilti spacing.

i' DRILLING ANCHOR BOLT HOLES 1.
If the first anchor bolt hole cannot be drilled at original design location because of rebar, relocate it in an out-wardly direction (away from steel member attachment) a short distance.
Continue moving outwardly until hole can be successfully drilled.
2.
Locate remaining holes in such a way that the final bolt hole pattern is as symmetrical as possible.

9/3/80 SUBSTITUTION OF ANCHOR BOLTS 1.
If the new anchor bolt location varies from the original location, less than or equal to 2 inches, then use anchor size as specified on bill of material.
2.
If new anchor bolt location is greater than 2 inches from original bolt location, substitute the next larger size anchor bolt with the greatest stocked length. This is pro-viding that the minimum Hilti bolt spacing criteria is met for that particular Hilti bolt size.
3.
If next size anchor bolt cannot be installed due to spacing requirements, increase bolt length to the greatest stocked length of the original bolt diameter.
In the case of 1" x 12" Hiltis, substitute with " Super" Hiltis of equal length.
NOTE:
Anchor bolt embedment length cannot exceed 80% of the thickness of the concrete slab or wall being attached to.
4.
All structural steel attachments to base plates (i.e., wide flange, structural tubing, channel, etc.) must always be s
within the inner confines of the bolt hole pattern.
