BC1:2012 Design Guide on Use of Alternative Structural Steel to BS 5950 and Eurocode 3
This is the 2nd edition of the design guide BC1 which serve as Singapore's national code of practice for the use of alternative structural steel materials in design to the British Standard "BS 5950 Structural Use of Steelwork in Building" and Eurocode 3 "EN 1993 Design of Steel Structures", including those maufactured to British and European Standards. Where applicable, Eurocode 3 refers to the suite of Structural Eurocodes adopted under Singapore Standards SS EN 1993 as well as the Signapore National Annexes to SS EN 1993. Steel materials not covered in BS 5950 and Eurocode 3 by default shall be allowed with or without restrictions if they are in comliance with the provisions of this design guide.
This design is expanded to cover additional new steel as well as re-use steel materials previously not considered for applications related to earth retaining or stabilizing structures such as steel strutting system and sheet piles only. The key objective is to ensure that only adequate (in terms of material performance) and reliable (in terms of quality assurance) steel materials, regardless of the standards to which the materials are manufactured to, are used in the design of permancent and temporary structural steelworks to ensure quality and public safety.
This design guide only gives provisions for structural design based on BS 5950 and Eurocode 3, and therefore only serves as guidance at the design stage. It has been assumed in the drafting of this design guide that the execution of its provisions is entrusted to appropriately qualified persons, in compliance with appropriate execution standards to control materials, fabrication and erection of steelwork.
As a code practice, this design guide takes the form of guidance and recommendations. It should not be quoted as if it was a specification and particular care should be taken to ensure that claims of compliance and not misleading. Reference for additional design recommendations other than those given in this design guide shall be made to relevant parts of BS 5950 and Eurocode 3.

FACTORY PRODUCTION CONTORL CERTIFICATES
SSSS has discontinued the FPC Listing. Users are encouraged to contact the certified bodies on FPCs.
FREQUENTLY ASKED QUESTIONS
FPC-FAQ1
Who is BC1 applicable to?
Where a submission is being made to BCA for structural plan approval,
structures with steel elements being submitted for approval would have to meet
BC1 requirements.
FPC-FAQ2
Obtaining FPCs for structural bolts and nuts is proving difficult
(up to 6th March 2009).
What is BCA’s position regarding bolts and nuts
having no FPC certificates? How will they be treated?
As of 1st January 2009, structural bolts and nuts are to meet BC1 requirements.
Without FPC, the bolts and nuts are treated as Class 3.
However, the supplier may wish to qualify the bolts and nuts for Class 2,
subject to meeting the recommendations within BC1 for testing and the
relevant British Standards for sampling.
FPC-FAQ3
Where can I find a list of certification agencies acceptable to BCA?
Are there any other certification agencies acceptable to BCA apart from
those listed (e.g. CARES, Universitat Karls ruhe (TH))?
The list of certification agencies acceptable to BCA can be found in Annex B
within the Explanatory Notes for BC1:2008.
Reference to be made to BCA on certification agencies not currently
listed in Annex B of the Explanatory Notes for their acceptance.

FPC-FAQ4
Does a structural steel designer have to design his structure base on Class 2
materials because he anticipates a lack of availability of Class 1 materials?
FPC requirement is not an excuse for a designer to over-design a structure.
It is a means for ensuring material quality by ensuring manufacturers have
undergone a quality audit.
Over-designing steel structures is not advantageous to the developer
because they will have to assume the additional cost.
Therefore it is advised that the designer still approach designs
on the assumption of the availability of Class 1 materials.
FPC-FAQ5
Are there are any mills in China where they have FPC/CE mark for steel sections
(ie I-beams, columns, angles, channels etc).
Feedback from industry is that there are no mills with FPC in China
where they can source for steel sections.
There are manufacturers of steel sections in China with FPC certificates.
Reference can be made at www.ssss.org.sg for examples.
FPC-FAQ6
For structural steel materials (i.e. plates and sections) that are manufactured
to BC1 certified specifications but the manufacturer is unable to provide an FPC,
what is the testing required to classify such materials to be Class 2?
Reference should be made to Appendix B within BC1.
FPC-FAQ7
Can steel specifications and grades not listed within BC1 be certified
by accredited assessors?
Using steel sections in JIS Grade SS400 as an example, since this grade
is not a certified specification within BC1, an FPC issued for Grade SS400
is not acceptable within the guidelines of BC1.
FPC-FAQ8
Can JIS Grade SS400 be used without FPC certificate?
No.
FPC-FAQ9
Who can I direct queries or feedback on FPCs to?
Queries or feedback with regard to Factory Production Certifications issued by the respective certification agencies in compliance with BC1 can be directed to their email contacts listed below.
