4 3.2.2.2 Monitoring shall be performed by using the " Recipient Trace" issued

, to each satellite and the several control numbers by the central DCC, which will indicate:

1. Those documents they are shown as having
2. Appropriate revision of each document
3. The number of copies of the document they have.

To monitor the design change logs, the' monitoring team will compare the Master DCC logs with satellite and control number logs. When that has been done, the physical design change files shall be

checked at each file location.

3.2.2.3 The monitoring team group leader shall write a memo to the DCC Supervisor indicating the monitoring activity has been completed and noting any discrepancies and corrective action taken. These monitoring reports shall be maintained in the DCC central office.

e. Where bolts are used on surfaces having slopes greater than 1-in-20 with a plane normal to the bolt axis, beveled washers shall be provided to give full bearing to the heau or nut.
f. Threaded bolts on friction-type connections shall be tightened with properly calibrated wrenches or by turn-of-nut method. Threaded bolts on bearing-type connections shall be tightened snug tight to prevent -

the nuts from loosening and falling off accidentally.

These requirements shall prevail unless otherwise noted on Engineering drawings.

NOTE: High strength steel bolts for bearing connections may be installed as a minimum snug tight.

g. When " Turn-of-nut" method is used for bolt tightening , <

the impact wrench or other pneumatic device does not l 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 corstruction:

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 ordinan spud wrench).
2. All the nuts shall then be match-marked using an approved indus trial 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 2.

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.
h. When using the " Calibrated Wrench" method for tightening bolts, the following steps will be followed by construction:
1. Impact wrench shall be calibrated prior to use each morning and afternoon for each adjusted tension setting.
2. Impact wrenches shall be recalibrated at any time significant changes are made in the equipment; i.e., air hose length changed by more than 200 feet or a significant difference is noted in the condition of the bolts, nuts, or washers.
3. By use of Bolt-Tension Calibrator adjust impact wrench until 3 consecutive bolts are tightened to required tension; (See Attachment 3 for required tension).
4. Use new bolt and nut each time the calibrator is used, i.e., 3 bolts tightened require 3 -new bolts and nuts; if a washer is to be used in the structure, then a washer shall also be used when calibrating the impact wrench.

5. When several bolts are installed in a single joint, the impact wrench shall be returned to

" touch-up" bolts previously tightened to assu re that any bolts which may have been loosened by the tightening of subsequent bolts are tightened to the prescribed amount.

i. When Richmond inserts are used, thread engagement into the insert shall be at least 2 X the bolt diameter +

1/ 8" . Therefore, the required length of the bolts used = [(2 x bolt diameter) + 1/8 inch] + [ grout -

thickness + thickness of structural member attached

+ thickness of washer (as applicable)].

J. When field connections are to be made by use of A325 or A490 bolts and tightened with a calibrated torque wrench, a hardened flat washer shall be used under the turned element and shall be tightened as follows:

ASTM A-325 ASTM A490 Bolt Size Torque Torque

(Inches) (Ft. Lbs.) (ft. lbs.)

1/2 93 5/8 228 3/4 387 500 7/8 518 650 1 725 1350 1 1/4 - 2620 1 1/2 - 4565

k. A490 and Galvanized A325 bolts shall not be reu.;ed. Other A325 bolts may be reused if approved by Eng'neering.

Retightening previously tightened bolts which may have been loosened by the tightening of adjacent bolts shall not be considered as a reuse.

1. ASTM A-449 bolts may be substituted for A-325 bolts,
m. ASTM A 307 bolts shall be tightened to a " snug tight" condition.

3.8 H0LES All holes in structural steel shall be punched or drilled.

. No holes shall be made or enla rged by burning without approval by designer.
