GENERAL PROGRAM GUIDELINES
A. Purpose of Special Inspection: Special Inspection is the monitoring of the materials and workmanship
that are critical to the integrity of the building structure. It is a review of the work that the contractors and
their employees to assure that the approved plans and specifications are being followed and that relevant
codes and ordinances are being observed. The special inspection process is in addition to those inspections
conducted by the municipal building inspector and by the engineer or architect of record as part of periodic
structural observation. The special inspectors furnish continuous or periodic inspection as prescribed in
IBC 1704 for that construction which requires their presence. Good communication between the special
inspector and the designers, contractor, and building department is essential to project quality assurance.
B. Duties and Responsibilities of the Special Inspector: Though not required by code, special inspectors
and/or inspection agencies can document acceptance of their responsibilities and scope of work for a
project by signing an agreement that includes a detailed schedule of services, commonly known as the
Special-Inspection and Testing Agreement and the Special-Inspection and Testing Schedule. Duties of
special inspectors and\or inspection agencies include the following:
1. Signify presence at job site. Special inspectors should notify contractor personnel of their
presence and responsibilities at the job site. If required by the building official, they shall sign in
on the appropriate form posted with the building permit.
2. Observe assigned work. [IBC Section 1704] Special inspectors shall inspect all work for which
they are responsible for conformance with the building department approved (stamped) plans and
specifications and applicable provisions of the IBC.
3. Signify presence at job site. Special inspectors should notify contractor personnel of their
presence and responsibilities at the job site. If required by the building official, they shall sign in
on the appropriate form posted with the building permit.
4. Provide timely reports. The special inspector should complete written inspection reports for each
inspection visit and provide the reports on a timely basis determined by the building official. The
special inspector or inspection agency shall furnish these reports directly to the building official,
engineer, or architect of record, and others as designated. [IBC Section 1704.1.2] These reports
should be organized on a daily and weekly format and may be submitted weekly at the option of
the building official. In these reports, special inspectors should include:
a. Describe inspections and tests made, with applicable locations b. Indicate how nonconforming items were resolved
c. List unresolved items, parties notified, time and method of notification
d. Itemize changes authorized by the engineer or architect of record if not included in the
nonconforming items.
5. Submit final report. Special inspectors or inspection agencies shall submit a final signed report to
the building department stating that all items requiring special inspection and testing were fulfilled
and reported, and to the best of their knowledge, in conformance with the approved plans,
specifications, and the applicable provisions of the IBC. [IBC Section 1704.1.2] Items not in
conformance, unresolved items, or any discrepancies in inspection coverage (i.e. missed
inspections, periodic inspection when continuous inspection was required, etc) should be
specifically itemized in this report.
C. Duties and Responsibilities of the Project Owner: The project owner, the engineer, architect of record,
or an agent of the owner is responsible for funding special inspections services. The special

inspector\agency shall not be in the employ of the contractor, subcontractor, or material supplier. [IBC
Section 106.3.5] In the case of an owner\contractor, the special inspector\agency shall be employed as
specified by the building official.
D. Duties and Responsibilities of the Design Professional in Responsible Charge: The design professional
in responsible charge should be a consenting party by written acknowledgement of special inspection and
testing agreements. The design professional in responsible charge has many duties and responsibilities
related to special inspection, including the following:
1. Prepare special inspection program. The design professional in responsible charge shall list the
items for which special inspection is required; and shall indicate any items for which the IBC or
the building official approves periodic inspection and the frequency of such inspection. The design
professional in responsible charge should coordinate with the project owner in the selection of
special inspectors [IBC Section 1704.1] and is required to list special inspectors and their duties
on the special inspection program. The standard of the industry for employing a qualified
inspection agency is its compliance with the requirements of ASTM E-329. The choice of special
inspector should include the following considerations:
a. Project size and complexity: experience with similar projects
b. Inspection staffing: sufficient qualified inspectors
c. Site location: proximity of inspection and testing facilities
d. Off-site inspection: capabilities for inspecting at remote locations
E. Duties and Responsibilities of the Contractor: The contractor’s duties include the following:
1. Notify the special inspector. The holder of the building permit or their duly authorized agent is
responsible for notifying the special inspector or agency regarding individual inspections as
required by the building department. [IBC Section 109.5] Adequate notice shall be provided so
that the special inspector has time to become familiar with the project.
2. Provide access to approved plans. The contractor is responsible for providing the special
inspector access to approved plans. [IBC Section 106.3.1]
3. Retain special inspection records. When required by the building official, the contractor is
responsible for retaining, at the job site, all special inspection records submitted by the special
inspector, and providing them for review to the building department’s inspector upon request.
F. Duties and responsibilities of the Building Official: Of all the team members involved in the construction
process, the building official is the only one with the legal authority to enforce the special inspection
provisions of the code. [IBC Section 104.4] The employment of a special inspector or agency shall not
relieve the building department of responsibility for progress or called inspections as required by the code.
Building department inspections of items also requiring special inspection should not be signed off without
the concurrence of the special inspector.
The specific duties and responsibilities of the building official relating to he special inspection include the
following:
1. Review submittal documents for compliance with special inspection requirements. The
building official is charged with the legal authority to review the plans, specifications, special
inspection program, and other submittal documents for the compliance with code requirements.
[IBC Section 104.2, 106.3, 106.5]
2. Approve special inspection program. The building official is responsible for approving the
special inspection program submitted by the design professional in responsible charge [IBC
Section 1704.1] and may require a preconstruction conference to review the program with all
appropriate members of the construction team.
3. Approve special inspectors/inspection agencies. The building official is responsible for
determining the competence of special inspectors for the types of work they will be inspecting.
[IBC Section 1704]
4. Monitor special inspection activities. The building official should monitor the special inspection
activities at the job site to assure that qualified special inspectors are performing their duties when
work requiring special inspection is in progress.
5. Review inspection reports. The building official receives and reviews special inspection progress
reports and final reports for conformance with the approved plans, specifications, and
workmanship provisions of the code. [IBC Section 1704.1.2]
6. Perform special inspection. The building official should not perform the final inspection and
approval of a project [IBC Section 109.3.10] until the final special inspection report has been
reviewed and approved.
The use of special inspectors is not discretionary. IBC Section 1704 clearly states the conditions under
which they must be utilized, but there is a provision for the building official to waive the special inspection
for work of a minor nature.
It is the responsibility of the building official to determine the competency of special inspectors. The IBC
does not make specific requirements for the determination of an inspector’s qualifications, but that in no
way lessens the importance of being selective in this crucial process.
A qualified special inspector usually has skills that are significantly more specialized than those of regular
municipal inspectors. A municipal inspector is required to have a general knowledge of a great number of
code requirements, whereas special inspectors focus on limited areas of structural inspection and materials
testing.
G. Duties and Responsibilities of the approved fabricator Special inspections required by this code are not
required where work is done on the premises of a fabricator registered and approved to perform such work
without special inspection. Approved shall be based upon review of the fabricator’s written procedural and
quality control manuals and periodic auditing of fabrication practices by an approved special inspection
agency. At completion of fabrication, the approved fabricator shall submit a certificate of compliance to the
building official stating that the work was performed in accordance with the approved construction
documents.
