International Building Code Section 1707


International Building Code 1707.1

Special inspections for seismic resistance. Special
inspections itemized in Sections 1707.2 through 1707.10,
unless exempted by the exceptions of Section 1704.1, are
required for the following:
1. The seismic-force-resisting systems in structures
assigned to Seismic Design Category C, D, E or F, as
determined in Section 1613.
2. Designated seismic systems in structures assigned to
Seismic Design Category D, E or F.
3. Architectural, mechanical and electrical components in
structures assigned to Seismic Design Category C, D, E
or F that are required in Sections 1707.7 and 1707.8.

International Building Code 1707.10

Seismic isolation system. Periodic special inspection
is required during the fabrication and installation of isolator
units and energy dissipation devices that are part of the seismic
isolation system.

International Building Code 1707.2

Structural steel. Continuous special inspection is
required for structural welding in accordance with AISC 341.
Exceptions:
1. Single-pass fillet welds not exceeding 5/16 inch (7.9
mm) in size.
2. Floor and roof deck welding.

International Building Code 1707.3

Structural wood. Continuous special inspection is
required during field gluing operations of elements of the seismic-
force-resisting system. Periodic special inspection is
required for nailing, bolting, anchoring and other fastening of
components within the seismic-force-resisting system, including
wood shear walls, wood diaphragms, drag struts, braces,
shear panels and hold-downs.
Exception: Special inspection is not required for wood
shearwalls, shear panels and diaphragms, including nailing,
bolting, anchoring and other fastening to other components
of the seismic-force-resisting system, where the fastener
spacing of the sheathing is more than 4 inches (102 mm) on
center (o.c.).

International Building Code 1707.4

Cold-formed steel framing. Periodic special inspections
is required during welding operations of elements of the
seismic-force-resisting system. Periodic special inspection is
required for screw attachment, bolting, anchoring and other
fastening of components within the seismic-force-resisting
system, including struts, braces, and hold-downs.

International Building Code 1707.5

Pier foundations. Special inspection is required for
pier foundations for buildings assigned to Seismic Design Category
C, D, E or F in accordance with Section 1613. Periodic
special inspection is required during placement of reinforcement
and continuous special inspection is required during
placement of the concrete.

International Building Code 1707.6

Storage racks and access floors. Periodic special
inspection is required during the anchorage of access floors
and storage racks 8 feet (2438 mm) or greater in height in structures
assigned to Seismic Design Category D, E or F.

International Building Code 1707.7

Architectural components. Periodic special inspection
is required during the erection and fastening of exterior
cladding, interior and exterior nonbearing walls and interior
and exterior veneer in structures assigned to Seismic Design
Category D, E or F.
Exceptions:
1. Special inspection is not required for architectural
components in structures 30 feet (9144 mm) or less in
height.
2. Special inspection is not required for cladding and
veneer weighing 5 psf (24.5 N/m2) or less.
3. Special inspection is not required for interior
nonbearing walls weighing 15 psf (73.5 N/m2) or less.

International Building Code 1707.8

Mechanical and electrical components. Special
inspection for mechanical and electrical equipment shall be as
follows:
1. Periodic special inspection is required during the anchorage
of electrical equipment for emergency or standby
power systems in structures assigned to Seismic Design
Category C, D, E or F;
2. Periodic special inspection is required during the installation
of anchorage of other electrical equipment in
structures assigned to Seismic Design Category E or F;
3. Periodic special inspection is required during installation
of piping systems intended to carry flammable, combustible
or highly toxic contents and their associated
mechanical units in structures assigned to Seismic
Design Category C, D, E or F;

?
4. Periodic special inspection is required during the installation
of HVAC ductwork that will contain hazardous
materials in structures assigned to Seismic Design Category
C, D, E or F; and
5. Periodic special inspection is required during the installation
of vibration isolation systems in structures
assigned to Seismic Design Category C, D, E or F where
the construction documents require a nominal clearance
of 0.25 inches (6.4 mm) or less between the equipment
support frame and restraint.

International Building Code 1707.9

Designated seismic system verifications. The special
inspector shall examine designated seismic systems requiring
seismic qualification in accordance with Section 1708.5 and
verify that the label, anchorage or mounting conforms to the
certificate of compliance.
