These qualifications are in addition to qualifications specified in other sections of the Chicago Construction Codes. The owner shall make this documentation available to the building official upon request.
The registered design professional in responsible charge and engineers of record involved in the design of the project are allowed to act as the special inspection agency and their personnel are permitted to act as special inspectors for the work designed by them, provided they qualify as special inspectors.
1704.2.1.1 Evidence of qualifications.
A special inspection agency shall provide all information as necessary for the owner to determine that the agency meets the applicable requirements specified in Sections 1704.2.1.1.1 through 1704.2.1.1.3.

Reports shall indicate that work inspected or tested was or was not completed in conformance to permitted construction documents. Discrepancies shall be brought to the immediate attention of the contractor for correction. If they are not corrected, the discrepancies shall be brought to the attention of the building official and to the registered design professional in responsible charge prior to the completion of that phase of the work. The building official may require that a final report documenting required special inspections and tests, and correction of any discrepancies noted in the inspections or tests, be submitted to the building official prior to occupancy."
5. Revise the last sentence of Section 1704.2.5.1 to read:
"At completion of fabrication, the fabricator shall submit a certificate of compliance to the owner stating that the work was performed in accordance with the permitted construction documents. The certificate of compliance shall be made available to the building official."

11. Revise Section 1704.5, item 7, by replacing "Seismic Design Category B, C, D, E or F" with "Seismic Design Category C or D."

"1704.6 Structural observations.
Where required by the provisions of Section 1704.6.1 or 1704.6.2, the owner shall employ a registered design professional to perform structural observations. Structural observation does not include or waive the responsibility for the inspections required by Chapter 5 of the Chicago Construction Codes Administrative Provisions or the special inspections in Section 1705 or other sections of this code.
Prior to the commencement of observations, the structural observer shall submit to the owner a written statement identifying the frequency and extent of structural observations. The statement shall be made available to the building official.
At the conclusion of the work included in the permit, the structural observer shall submit to the owner a written statement that the site visits have been made and identify any reported deficiencies that, to the best of the structural observer’s knowledge, have not been resolved.
