Revise as follows:
1705.3 Concrete construction. The special inspections and verifications for concrete construction shall be as
required by this section and Table 1705.3.
Exception: Special inspections shall not be required for:
1. Isolated spread concrete footings of buildings three stories or less above grade plane that are fully supported
on earth or rock.
2. Continuous concrete footings supporting walls of buildings three stories or less above grade plane that are
fully supported on earth or rock where:
2.1. The footings support walls of light-frame construction;
2.2. The footings are designed in accordance with Table 1809.7; or
2.3. The structural design of the footing is based on a specified compressive strength, f′c, no greater than 2,500
pounds per square inch (psi) (17.2 Mpa), regardless of the compressive strength specified in the approved
construction documents or used in the footing construction.
3. Nonstructural concrete slabs supported directly on the ground, including prestressed slabs on grade, where
the effective prestress in the concrete is less than 150 psi (1.03 Mpa).
4. Concrete foundation walls constructed in accordance with Table 1807.1.6.2.
5. Concrete patios, driveways and sidewalks, on grade.
1705.11.6 Mechanical and electrical components. Special inspection for mechanical and electrical components
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 anchorage of other electrical equipment in structures
assigned to Seismic Design Category E or F;
3. Periodic special inspection is required during the installation and anchorage of piping systems designed to
carry hazardous materials 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 and anchorage of ductwork designed to carry
hazardous materials in structures assigned to Seismic Design Category C, D, E or F; and
5. Periodic special inspection is required during the installation and anchorage of vibration isolation systems in
structures assigned to Seismic Design Category C, D, E or F where the approved construction documents
require a nominal clearance of 1/4 inch (6.4 mm) or less between the equipment support frame and restraint.
1705.12.3 Seismic certification of nonstructural components. The registered design professional shall specify
on the approved construction documents the requirements for certification by analysis, testing or experience data for
nonstructural components and designated seismic systems in accordance with Section 13.2 of ASCE 7, where such
certification is required by Section 1705.12.
2105.1 General. A quality assurance program shall be used to ensure that the constructed masonry is in compliance
with the approved construction documents.
The quality assurance program shall comply with the inspection and testing requirements of Chapter 17.
2105.2.2.2.1 General. The compressive strength of clay and concrete masonry shall be determined by the prism
test method:
1. Where specified in the approved construction documents.
2. Where masonry does not meet the requirements for application of the unit strength method in Section
2105.2.2.1.
2204.2.1 Anchor rods. Anchor rods shall be set in accordance with the approved construction documents. The
protrusion of the threaded ends through the connected material shall fully engage the threads of the nuts, but shall
not be greater than the length of the threads on the bolts.
2207.4 Steel joist drawings. Steel joist placement plans shall be provided to show the steel joist products as specified
on the approved construction documents and are to be utilized for field installation in accordance with specific project
requirements as stated in Section 2206.2. Steel placement plans shall include, at a minimum, the following:
1. Listing of all applicable loads as stated in Section 2206.2 and used in the design of the steel joists and joist
girders as specified in the approved construction documents.
2. Profiles for nonstandard joist and joist girder configurations (standard joist and joist girder configurations are as
indicated in the SJI catalog).
3. Connection requirements for:
3.1 Joist supports;
3.2 Joist girder supports;
3.3 Field splices; and
3.4 Bridging attachments.
4. Deflection criteria for live and total loads for non-SJI standard joists.
5. Size, location, and connections for all bridging.
6. Joist headers.
Steel joist placement plans do not require the seal and signature of the joist manufacturer’s registered design
professional.
SECTION 202
DEFINITIONS
SPECIFIED COMPRESSIVE STRENGTH OF MASONRY, f’m. Minimum compressive strength, expressed as force
per unit of net cross-sectional area, required of the masonry used in construction by the approved construction
documents, and upon which the project design is based. Whenever the quantity f’m is under the radical sign, the
square root of numerical value only is intended and the result has units of pounds per square inch (psi) (MPa).
Reason:
The purpose for the proposal is to update references to “construction documents” in the building code. Section
107.1 contains the requirements for the submittal of construction documents with each permit application and Section
107.3 requires the building official to approve the construction documents for permit issuance. The building code
typically specifies “construction documents” before permit issuance and “approved construction documents” after
permit issuance but there are exceptions and this proposal adds “approved” for those cases.
The instances of “construction documents” not preceded by “approved” in the building code typically occur in
provisions that require the designers to specify information in the construction documents or to design the building or
structure to meet specified requirements. Compliance with these provisions is only possible before the construction
documents are approved. These are located in Sections 104.2, 105.3(4), 105.3.1, 105.4, 107.1, 107.1, 107.2, 107.2.1,
107.2.2, 107.2.3, 107.2.4, 107.2.5, 107.3.1, 107.3.2, 107.3.3, 107.3.4.1, 414.1.3, 907.1.1, 909.2, 909.3, 909.4,
909.21.2, 1603.1, 1603.1.6, 1603.1.9, 1607.5, 1705.11.6(5), 1705.12.3, 1901.3, 2101.3, 2101.3.1, 2207.2, 2403.2,
3103.2, 3303.2, G104.2, H105.2, K104.1, K104.2 and K105.5.
The instances of “approved construction documents” in the building code are located in Sections 107.4, 107.5,
114.4, 202 (“certificate of compliance” and “structural observation”), 1704.2.4, 1704.2.5.1, 1704.2.5.2, 1705.2-Exc.,
1705.6, 1705.8, 1705.9, 1705.13, 1705.14, 1810.3.5.2.2-Exc., 1910.7, 2207.5, and 2403.1; and Table 1705.2.2. Note
that “approved” precedes “geotechnical report and the construction documents” in Sections 1705.6, 1705.8 and
1705.9. In Section 1705.7, however, “approved” precedes “instruction documents,” which is apparently an advertent
error made during the development of the 2012 IBC. On August 9, 2011, I submitted a request to the ICC that this be
posted as errata but, as of January 3, 2012, the submittal deadline for Group A change proposals, a posting for the
2012 IBC had not yet been made on the ICC website.
All instances of “construction documents” in the building code were considered and are either in the proposal or are
listed in the paragraphs immediately above.
A separate proposal (Sxx-12/13) places the provisions of Section 1705.12.3 into two subsections (Sections
1705.12.3 and 1705.12.4) to provide effective charging language for the corresponding provisions in ASCE 7-10.
Should both proposals be approved by the ICC membership, our intent is that Sections 1705.12.3 and 1705.12.4 both
read: “…the registered design professional shall specify on the approved construction documents the requirements…”
A separate proposal (Sxx-12/13) deletes the definition of “specified” in Section 202. Should both proposals be
approved by the ICC membership, our intent is that the definition be deleted.
Cost Impact: The code change proposal will not increase the cost of construction.
