1. Introduction The quality requirements contained in this document has been developed specifically for steel

structures fabricated to the New Zealand Steel Structures (NZS 3404.1) and Welding Standards

(AS/NZS 1554 series) in order to safeguard safety and reliability of our structural steelwork in New

Zealand seismic environed.

The document takes into account a risk-based approach introducing four Construction Categories

(CC) for steel structures covering a wide range of applications. While CC1 and CC2 apply for low risk

structures such as low rise buildings, car parks, etc., CC3 and CC4 are specified for critical seismic

applications, railway bridges, etc.

Construction Categories are defined and allocated to the structural steelwork and/or its individual

components by the Design Engineer. Guidance on specifying construction categories is given the SFC

Framework – Part 3 document. .

In order to undertake structural steelwork to the requirements of the individual Construction

Category, the fabricator shall be certified to this Construction Category before the fabrication work

commences.

This document sets certification requirements for the Construction Categories referred to as Steel

Fabrication Certification Scheme (SFC).

The scheme is largely based on the requirements of the above standards taking into account a

quality management standard for welding AS/NZS ISO 3834. A graphic overview of the SFC Scheme is

given below:

Overview of the SFC Scheme

2. Scope This document sets out minimum requirements for the construction of structural steelwork

fabricated to NZS 3404.1 and to the AS/NZS 1554 standard series. It applies to complete structures,

individual members and components and manufactured components pre-fabricated for inclusion in

a steel structure.

It covers buildings, general structures, crane runway girders, monorails, roadway bridges, railway

bridges and pedestrian bridges. Its application includes complete structures, individual members and

manufactured components subject to seismic actions or to fatigue.

The requirements of this document are based on NZS 3404.1 1997, NZS 3404:2009 and AS/NZS 1554

standard series as well as Structural Steelwork Fabrication and Erection Code of Practice developed

in cooperation with Australian Steel Institute.

6. Materials of construction

6.1. Materials A product that used for fabricating a component and which remains as part of it shall be subject to

full or partial traceability as subject to the requirements of Construction Categories and Customer’s

specification.

6.2. Full traceability Full traceability requires all material (including cleats, brackets etc.) to be traceable to the material

test certificates supplied to the fabricator, at all stages of fabrication and erection

6.3. Partial traceability The delivered material must be accompanied by test certificates to verify that the steel grade is

correct. Once issued from stock into the manufacturing/fabrication system, the grade of steel shall

remain identifiable, but individual plate and section components need not be traced back to the test

certificate for example by the heat number. Copies of test certificates shall be retained in the project

documentation. The grade of each piece of an assembled component shall recorded for example on

as built drawings.

7. Requirements for Construction Category Normative requirements for the Construction Category are given in the Table 2. Compliance of the

Fabricator with requirements related to the selected Construction Category shall be verified by a

third party audit conducted by the SFC Certification Body that shall issue a corresponding certificate.

Compliance with a higher Construction Category also covers lower Construction Categories.

NOTES:

1. Compliance of the Fabricator with all normative requirements of AS/NZS 1554.1 shall be verified by a

third party audit conducted by the Certification Body.

2. Secondary attachments as designated by the Design Engineer may require only partial traceability

subject to agreement between fabricator and Design Engineer.

3. The fabricator shall be certified by a third party audit to AS/NZS ISO 3834 Part 2.

4. The minimum extent of non-destructive examination (NDE) shall be specified by the Design Engineer.

Guidance is given in NZS 3404.1:2009, Section 8.

5. The following shall be undertaken by the Design Engineer or his/her nominated representative before

prior to the start of welding:

a. The Design Engineer shall specify welding requirements in accordance with AS/NZS 1554 Part

1 to 7 as applicable. This includes weld category, weld size and extent of inspection [ref.

clause 14.3.4, NZS 3404.1:1997]

b. All welding requirements shall be adequately reviewed by the Design Engineer, who on the

basis of experience or qualifications is competent to undertake the review. The extent of

review to be undertaken shall be nominated by the Design Engineer, taking into account

those materials and workmanship factors which are likely to influence the ability of the

finished construction to perform in the predicted manner [Ref. clause 1.6.3.1 NZS

3404.1:1997].

c. The fabricator’s welding procedures shall be approved for the job by the Design Engineer or

by his/her nominated representative who is competent to undertake the review prior to the

start of welding [Ref. clause 1.6.3.2 Note (4) NZS 3404.1:1997 Part 1].

d. The extent of non-destructive examination (NDE) shall be nominated by the Design Engineer.

6. Traceability of welders to individual welds shall be available either by documentation (e.g. weld plan)

or welder ID stamp for primary connection welds.

7. Documentation allowing traceability of welding procedures (WPS) to individual welds shall be

available.


7 | P a g e

8. The fabrication supervisor shall have sufficient technical knowledge and experience suitable for the

scope of work. Competency of fabrication supervisor should be verified through the professional

interview.

9. Sub-contractors should comply with the same Construction Category as the main fabricator. However,

a lower level may be appropriate, depending on the extent of the sub-contract and the services or

products provided. It is the responsibility of the main fabricator to ensure that the sub-contractor’s

activities are controlled according to the applicable Construction Category. This may require auditing

of a sub-contractor’s premises by the main fabricator.

8. Welding requirements - ISO 3834 Welding is a so-called “special” process, which means that a complete verification of the welded join

is not possible without destroying it. Therefore, to ensure the proper quality of the welded product

and to optimise manufacturing cost, the whole welding process must be controlled from the very

start. For structural steel applications, this is achieved by applying a quality management system ISO

3834.

A key feature of this standard is the requirement to ensure that people with welding responsibilities

are competent to discharge those responsibilities. This is achieved by incorporation of another

standard: ISO 14731 “Welding Co-ordination – Tasks and responsibilities”.

Certification of the Fabricator to ISO 3834 Part 2 is normative for the Construction Category CC3 and

CC4. ISO 3834 is considered the key element of the SFC Scheme approximately covering two third of

the requirements of the SFC. Therefore the Scheme is sometimes referred to as ISO 3834 “PLUS”.

Elements of the ISO 3834 Part 2 are listed in the Table 3.

9. IIW MCS ISO 3834 The International Institute of Welding (IIW) has developed an integrated and specialised Certification

Scheme to assure companies’ compliance with ISO 3834. This Scheme is referred to as the IIW

Manufacturer Certification Scheme according to ISO 3834 (IIW MCS).

The IIW Rules establish the mechanism by which the the IIW Manufacturer Certification

Scheme according to ISO 3834 is implemented uniformly by all countries involved.

In New Zealand, IIW MCS ISO 3834, which is the part of the SFC, is provided by HERA ANBCC, the IIW

Authorised National Body for Company Certification.

10. Welding requirements of AS/NZS 1554 Design standard NZS 3404.1 requires all welded fabrication to comply with AS/NZS 1554 applicable

part. Therefore, for the Construction Category CC2, CC3 and CC4, compliance of the Fabricator with

all normative requirements of AS/NZS 1554.1 shall be verified by a third party audit conducted by

the Certification Body

A check list to assess compliance with normative requirements of NZS 3404.1 and AS/NZS 1554 is

given in the Appendix A.

11. Competency of Personnel Staff competency is a key element of the SFC. For all tasks assigned, staff shall be able to

demonstrate adequate technical knowledge to ensure satisfactory performance of the tasks

assigned.

Welding coordination is one of the key concepts of ISO 3834. That is why Fabricators must appoint

only competent personnel as the responsible welding coordinator (RWC) and supervisors taking into

consideration ISO 14731. A minimum recommended qualification for the Welding Supervisor is AS

2214. IIW qualification as International Welding Specialist (IWS) or higher is the recommended

option.

For Construction Category CC3 and CC4, welding coordination personnel shall demonstrate

“specific” and “comprehensive” technical knowledge to ISO 14731. Technical knowledge of the


9 | P a g e

welding coordinators is verified by a professional interview conducted by the assessors within the

scope of the product standards applied.

For Construction Category CC2, qualification of the welding supervisor shall be in accordance with

Section 4.12.1 Item (a) to (e), AS/NZS 1554.1.

Other staff members including welding inspectors, NDE personnel and welders shall also be suitably

qualified to carry out the welding procedures for which they will be employed. Qualification

requirements for are spelled out in this document.

12. Documentation and quality In any control system there is a need for documentation. The term documentation embraces a range

of different types of documents such as quality manual, procedures, records, instructions and

certificates.

SFC does not specifically require a quality management system. However, it identifies those

elements that shall be considered in order to demonstrate compliance with the Scheme.

Quality documentation required to confirm compliance with SFC are given in the Table 4

Table 4: Quality documentation required to confirm compliance with SFC (Normative)

Element Quality Documentation Description

1. Quality System Quality System Manual (QSM),

Quality Plans (QP),

Procedures,

Checklists, etc.

The fabricator shall operate an effective Quality System. The Quality System shall be documented in the Quality System Manual (QSM) and associated procedures. The QSM shall include following items:

a. Management’s commitment to the Quality System.

b. An organisation chart. c. Allocation of tasks and authority with

respect to the Elements of the system. d. Qualification of staff required to perform

assigned tasks. e. A document control procedures ensuring

that:

⎯ documents are maintained up to date,

⎯ those in receipt of documents are identified,

⎯ the latest issues of the documents are available at locations where they are used,

⎯ obsolete documents are withdrawn,

⎯ records are archived to avoid deterioration and to enable retrieval, and

⎯ records are not destroyed without authorization.

13. Essential steps to achieve SFC certification A Step-by-step procedure for certification of a quality management system to the requirements of

the Steel Fabricator Certification Scheme (SFC) is listed below. A fabricator considering achieving SFC

certification, as a first step, should establish compliance with welding requirements and then

address all other items of SFC.

Overview: Essential steps to achieve SFC certification

Step 1: The Fabricator contacts SFC in writing. The Scheme Manager sends to the Fabricator

all relevant SFC documentation. In order to provide the Fabricator with information

3 2 4 5

6 7 8 9

11 | P a g e

on the Scheme, a specific orientation meeting may be organised with the Fabricator

and Technical Experts

Step 2: The Fabricator defines the Construction Category and certification level required in

order to cover the range of structural steel products considered.

Step 3: The Fabricator establishes and implements a welding quality management system to

the requirements of the Construction Category (CC). For CC 3 and 4, the Fabricator

shall be certified to AS/NZS ISO 3834 Part 2. For CC 2, Compliance of the Fabricator

with all normative requirements of AS/NZS 1554.1 shall be verified by a third party

audit conducted by the SFC. This is usually performed within the same audit that

also covers other requirements of the SFC (see Step 4).

Step 4: The fabricator implements all other requirements of the SFC and applies for the

certification.

Step 5: Once the application has been accepted by the SFC, a pre-audit meeting will be

organised by the Scheme Manager and a contract signed.

Step 6: On receipt of the order from the Fabricator by SFC, the Scheme Manager will

appoint the Assessment Team that consists of the Lead Assessor and Assessor to

carry out an assessment and sign the contract.

Step 7: The Fabricator sends the Quality Manual and relevant documentation to the

Assessment Team, who then carries out a document review. Once the

documentation has been accepted an on-site audit by the Assessment Team is

conducted. The Audit can be conducted as a joint ISO 3834.2 (CC3&4) (or AS/NZS

1554 (CC2)) and SFC (other than welding), or as a SFC (other than welding) one in

case the Fabricator holds a current ISO 3834.2 certification.

Step 8: The audit report, a review of any corrective actions and a final report are submitted

to the Certification Panel of the SFC for approval.

Step 9: Once the final Audit report is satisfactory, a certificate confirming that the company

has proven its ability to fulfil the requirements of SFC will be issued. The Fabricator

shall not have nonconformities pending when the certificate is issued. The

Certificate is valid for a maximum of five years, subject to satisfactory annual

surveillance audits. The certificate is valid for the Construction Category the

Fabricator was assessed to.

The assessment audit using usually requires half a day. For the duration of the

ISO3834 audit.

Following the Fabricator’s application, the scope of certification can be extended to

a higher Construction Category. This step normally requires an audit visit.

Step 10: Annual Surveillance audits are required in order to maintain the SFC certification.

Step 11: Reassessment against SFC is required every five years (Step 6 to 9).

NOTE: Welding is recognised in ISO 9001 as “special processes” as the quality of welded products cannot be

fully verified by final inspection. Therefore, Section 1.7 of AS/NZS 1554.1:2011 requires the fabricator to

demonstrate that all welding and related activities are conducted under a suitable quality management

system. Such a system should comply with the requirements of AS/NZS ISO 3834.
