1 OVERVIEW

1.1 Configuration Standard Summary

This Configuration Standard Technical Order (CSTO) emphasizes the need for Special Inspections per Chapter 17, International Building Code (IBC). It clarifies the roles of owner, Authority Having Jurisdiction (AHJ), Building Official (BO), and Permit Applicant. It is issued in response to a High Potential (HIPO) MISHAP that resulted from inadequate design detail and inspection.

1.2 Applicability

This CSTO potentially applies to the design and construction surveillance of all category codes except land, in cases as specified in the IBC. It is especially applicable to structural connections, weight handling equipment mounting, and towers.

1.3 Roles and Responsibilities

The technical authority for this configuration standard is SILC Commander. Table 1-1 enumerates the roles and responsibilities for executing the standards defined in this technical order. The following “RASCI” codes are used:

R = Responsible: Those who do the work (typically only one Responsible per task).

A = Approver: The one ultimately accountable for the deliverable or task (must have only one Approver per task).

S = Supports: Those who provide resources, information, expertise or other assistance in completing of the task. A Supports role indicates more intensive and consistent involvement than just being identified in a Consulted role.

C = Consulted: Those whose opinions are sought (two-way communications).

I = Informed: Those who are kept up-to-date on progress (one-way communication).

2 TECHNICAL REQUIREMENTS

2.1 Organization

The Coast Guard has adopted the International Building Code as the design standard in Chapter 11, Civil Engineering Manual COMDTINST M11000.11C. This CSTO provides modifications to IBC Chapter 17, Special Inspections. It is organized by the same sections found in the IBC, with the following conventions:

[Addition] Indicates an added requirement for USCG projects.

[Deletion] Indicates the language in the IBC should be deleted for USCG projects.

[Replacement] Indicates language that is substituted in the IBC for USCG projects.

[Supplemental] Indicates additional information for interpreting the IBC when applied to USCG projects.

2.2 Modifications to IBC Chapter 17 Special Inspections

2.2.1 Section 1701 – GENERAL

1701.1 – Scope [Supplemental]

The IBC does not contemplate federal ownership of facilities or federal contracting mechanisms. When the USCG advertises a project, it is effectively granting the building permit (not other environmental permits). Hence, when interpreting the code, apply the following substitutions:

“Owner” COMDT (CG-43)

“Authority Having Jurisdiction” COMDT (CG-43)

“Building Official” SILC Commander

“Permit Applicant” The general or construction inspection contractor

2.2.2 Section 1703 – APPROVALS

1703.1.1 – Independence [Supplemental]

In consideration of efficiency, staffing limitations, and contracting workload, it is acceptable for a special inspection agency to be a subcontractor of either the construction surveillance contractor, when used; or of the general contractor when a separate construction surveillance contractor is not used.

1703.4 – Performance [Replacement]

New, unusual, or innovative materials, systems or methods previously untried by the Coast Guard may be incorporated into designs when evidence shows that such use is in the best interest of the Government for reasons of economy, lower life-cycle costs and/or quality construction. Supporting data, where necessary to assist in the approval of material or assemblies not specifically provided for in the code, must consist of valid evaluation reports from International Code Council Evaluation Service (ICC-ES), or other qualified testing and evaluation service with prior approval of the Building Official.

1703.4.1 – Research and Investigation [Deleted}

Delete the paragraph in its entirety.

1703.4.2 – Research Reports [Delete]

Delete the paragraph in its entirety.

2.2.3 Section 1704 – SPECIAL INSPECTIONS AND TESTS, CONTRACTOR

RESPONSIBILITY, AND STRUCTURAL OBSERVATIONS

1704.2.3 - Statement of special inspections [Replacement]

Replace the first paragraph with:

The Engineer of Record shall state any required Special Inspections on the project documents (drawings and specifications). The statement must be in accordance with Section 1704.3. A template for the Statement of Special Inspections may be found in Appendix A.

1704.4.6 – Structural Observations [Replacement]

Replace the first two sentences with:

When special inspections are called for in the project documents, the provisions of Section 1704.6.1 structural observations, must be performed by the Engineer of Record, or their designated representative, who must be a registered design professional.

Structural observation does not include or waive the responsibility for the inspections in Section 110 or the special inspections in Section 1705 or other sections of this code.

1704.7 – Special Inspector of Record [Addition]

When the provisions of Section 1704.6.1 apply, the services of a Special Inspector of Record (SIOR) must be retained by the Contractor as a third-party quality assurance agent, or must be provided by the Government. The SIOR must be either a licensed professional engineer in a state or territory of the project location, and must be involved in the project, and acceptable to the Building Official, and/or an International Code Council (ICC) certified inspector. The SIOR may be the project’s Engineer of Record as well. The SIOR qualifications shall be a submittal under the contract.

1704.7.1 – Duties of the Special Inspector of Record (SIOR) [Addition]

Insert from UFGS specifications (01 45 35 for DBB; 01 45 35.05 for DB)

1704.2 – Final Inspection Report [Addition]

When work requiring Special Inspections is completed and any nonconforming items are resolved to the satisfaction of the Engineer of Record, the Contractor shall notify the SIOR to submit a Final Special Inspection Report to the Contracting Officer, Engineer of Record, and Contractor. The Final Special Inspection Report must attest that the Special Inspection was performed on all work requiring Special Inspections and that any nonconforming work and corrections of all discrepancies were resolved to the satisfaction of the Engineer of Record and Contracting Officer. The Final Special Inspection Report must be signed, dated, and bear the name, seal and signature of the

SIOR.

2.2.4 Section 1705 – REQUIRED SPECIAL INSPECTIONS AND TESTS

1705.3.3 – Adhesive Anchors [Addition]

The Engineer of Record is required to determine the proof load (per ACI 318-19 Section 26.7.1(k)) to be used for field testing, and to indicate the in the construction documents which anchors are considered critical for testing.

SCHEDULE OF SPECIAL INSPECTIONS

Reference UFGS 01 45 35 for all requirements not noted as part of this schedule.

INSPECTION DEFINITIONS:

PERFORM: Perform these tasks for each weld, fastener or bolted connection, and required verification.

OBSERVE: Observe these items randomly during the course of each work day to insure that applicable requirements are being met. Operations need not be delayed pending these inspections at contractor’s risk.

DOCUMENT: Document, with a report, that the work has been performed in accordance with the contract documents. This is in addition to any other reports required in the Special Inspections guide specification.

CONTINUOUS: Constant monitoring of identified tasks by a special inspector over the duration of performance of said tasks.

PERIODIC: Special inspection by a special inspector who is intermittently present where the work to be inspected has been or is being performed.

The Seismic Design Category for this project is: ☐ A, ☐ B, ☐ C, ☐ D, ☐ E, ☐ F (check appropriate box)

DESIGNER NOTES (delete this box after reviewing):

1. This schedule contains minimum requirements. Do not delete applicable inspection tasks unless notes in blue indicate it is acceptable to do so.

2. Blue text = designers notes. The designer must review and edit all blue text in this schedule prior to inserting this schedule into the special inspections spec (UFGS 01 45 35).

3. Check section boxes with ANY inspection tasks applicable to your project. You may choose to delete unchecked sections or leave them in the schedule unchecked.

4. Individual rows/tasks that are not applicable to the project may be left in the section, as the inspector can determine whether they occur/apply (e.g. metal trusses in the light gauge framing section for example).

5. Design discipline sections are color coded for easier reference by designers. This schedule does NOT need to be printed in color.

6. When finished editing, delete this note box and save this schedule as a PDF and insert into the project specifications (special inspections section).
