A.2 SPECIAL INSPECTIONS
Special Inspections Scope:
Typical required inspections:
1 Epoxy bolts. No epxoy bolts are used on his project.
2 Welding of main structural members. There are no structural welded connections on this job. All connections are through bolted.
There is not a requirement for any special inspections on this project because the typical triggers for that requirement are not present.

4.1 HAND/GUARD RAILS ARE MADE UP OF A TOP RAIL WHICH SHALL BE 2"X2"X1/4" ANGLE
WITH A 1"X1 1/4"X1/4" ANGLE MIDSPAN AND 1"X1/4" FLAT BARS FOR THE REMAINING
COMPONENTS. ALL RAILS SHALL BE A MIN. 42" HIGH TO UPPER FACE OF TOP RAIL WITH 1/2"
PICKETS AT 4" O.C. MAX OR 1/8" CABLE RAILS SYSTEM AT 3 1/2" O.C. TENSIONED TO ALLOW
MAXIMUM FLEX TO NO MORE THAN 4". ALL ANGLE RAILS AND POSTS ARE 3/8" BOLTED
CONNECTIONS WITH ONLY NON-STRUCTURAL SHOP FABRICATED WELDING
CONNECTIONS AT THE TOP AND BOTTOM OF PICKETS. SEE NOTE 6.
4.2 RAILS AT THE FIXED UPPER RUN OF A CANTILEVER STAIR SHALL BE OF A LOW PROFILE 2"X1/4"
TO ALLOW THE LOWE CATILEVER STAIR'S STRINGER AND HAND RAIL TO PASS THEM WHEN
RAISED OR LOWERED.
5.ALL MAJOR FRAMING SUPPORT CONNECTIONS SHALL BE A MIN. OF (2) -1/2"X4 1/2" BOLTS OR
GREATER . ALL MINOR SUPPORT CONNECTIONS SHALL BE 3/8" BOLTS.
6.THERE IS NO SPECIAL INSPECTION WELDING WORK ON ANY FIRE ESCAPE COMPONENTS IN
THIS PROJECT. ALL WELDING IS SHOP FABRICATED AND ON MINOR SUPPORTS ONLY.
