d. Bolt heads and- nuts shall rest squarely against the metal or washer.
e. Where bolts are used on surfaces having slopes greater than 1-in-20 'with a plane nonnal to the bolt axis, beveled washers shall be provided to give full bearing to the head or nut.
f. When " Turn-of-nut" method is used for bolt tightening, the impact wrench or other pneumatic device does not require calibration. However, the device shall be of adequate capacity and sufficiently supplied with air to perfonn the required tightening of each bolt in approximately ten seconds. When this method is used, the following steps will be followed by construction:
1. All bolts in each joint shall first be brought to a " snug tight" condition (snug tight is defined as the tightness attained by a few impacts of an impact wrench or the full effort of a man using an ordinary spud wrench).
2. All the nuts shall then be match-marked using an approved industrial ma rker, i.e.: Nissen; which has certified contents.
3. All the bolts in the joint shall then be tightened

~ by the applicable amount of nut rotation specified in Attachment 4.

4. Tightening shall progress systematically fran the most rigid part of the joint to its freest edges.
5. There shall be no rotation during tightening of the part not turned by the wrench.
6. The end of all bolts shall be marked with the industrial marker when required nut rotation has been attained.

FSE-00159 detail drawings have been prepared for specific hanger fabrication. The FSE-00159 provides the basic support type as illustrated on the design 2323-S-900 series of drawings. Design changes against 2323-S series drawings shall be utitized by QC inspectors for inspection purposes and shall be used in conjunction with all appropriate CPSES Engineering approved design drawings. The QC Ins pector shall use the FSE-00159 only for location of cable tray

~

hanger, verify hanger unique number, and hanger elevation unless directed by the engineer with a Design Change Document regardless of the referenced document. Again attachments to concrete or embedded plates are shown for reference only. The detennination of detail to be used will be in accordance with design drawings and FSE-00179. If the engineer has provided the installation criteria for a support on a Design Change document, then QC verification should be per the Design Change drawing, di sregarding the FSE-159 NOTE: FSE-00159 detail drawings issued prior to 5-26-81 '

my not show the location of the support, and may

. not necessarily be revised to add the location of

the support. _ In cases where hangers are stacked and no location is provided on the FSE-159 series drawings, Engineering will provide location coordinates and elevation on appropriate design drawing. In cases where hangers are not " stacked" the FSE map drawings may be used for verification of hanger identification.

3.1.4.2 Configuration The QC Inspector shall verify the completed support is .in accordance with the design drawing- and applicable design

. change documents. This verification shall include the following attributes:

a. Support type
b. Support Member (s) shape (i.e., angle, channel, etc) and size
c. Location of members in accordance with design drawing

- dimensions including " work points" when shown 3.1.4.3 Use of Drawings for Rework .

.I the QC inspector for verifying the hanger unique neber for inspection of rework. In any case, where the proper unique neber is considered questionable (i.e., not readable, covered or , improperly stamped), then the FSE-00159 shall be used for verification.

" Stacked" hangers that are reinspected shall have the unique number of the hanger verified with the FSE-00159 drawings. ,

Once the hanger is identified by the FSE-00159 drawing, l

, physical identification of the unique number on the hanger is not' necessary, and inspection doceentation shall reference the applicable FSE-00159 drawing. Hangers that

'a re . reinspected shall not have their unique numbers restamped unless directed by the QC Supervisor.

3.1.5 Verification of Baseplates for Grouting An Inspection Report indicating . bearing (" Satisfactory or Unsatisfactory") shall be completed as required per Reference 1-F. .

3.1.6 Welding Inspection Welded cable tray, camponents, and supports shall be c inspected for acceptance per Reference 1-G.

t NOTE: Existing travelers that specify welding inspection i in accordance with procedures other than Reference 1-G or in accordance with procedures which have since been deleted shall be inspected in accordance wi th Reference 1-G. Addi tionally, previously approved generic travelers that require e fit-up inspections for skewed fillet welds are not s a requirement of this instruction or Reference 1-G.

.~ When this occurs, the traveler operation shall be marked "N/A per QI-QAP-11.10-2".

3.1.7 Pluo Welding Unused holes which are spaced 2" or less as measured center

, to center from a used or an unused hole shall be plug welded.

Otherwise, as long as there are no unused holes in the same cross-sectional plane as the used one, the unused holes need not be plug welded. Unused holes in the same cross-sectional

,'_ plane must be plug welded in accordanc, e with reference 1-H.

Plug welded holes shall be -inspected using the acceptance 4

g criteria of Reference 1-G.

, hangers shall be inspected in accordance with following criteria:

~

. a. Friction type clamps shall be installed on transverse rK '. , cable tray supports and shall be inspected to meet the requirements outlined in Paragraph 3.1.8.2b, c, and d.

NOTE: Areas accepted by monitor per previous u' revision of this instruction are not governed

, , by this requirement.

b. Proper bolt installation and bolt type , including

, connection of tray to clip and clip to hanger. See Attachment 5 for ASTM bolt type and marking.

1. All A307 bolts shall be snug tightened and shall

.. meet the applicable requirements of Paragraph 3.1.3.2 and should be " torque sealed" with Inspector's lacquer.

2. All high strength bolts (A-325 or approved substitute) shall be tightened per Paragraph 3.1.3.
