PREFACEThis handbook is a companion publication to the design guide BC1: 2012 which has been updatedto include design recommendations to both BS 5950 and SS EN 1993 provisions, and additionalsteel materials, including re-used steel materials.The main objective of this handbook is to provide clearer explanations on how to interpret and usethe design guide BC1: 2012, i.e. how to classify the steel into the different classes, and the criteriato qualify for certified, non-certified and re-used steel materials.Where appropriate, both British Standards and Eurocode’s symbols are used in this handbook.As a handbook, it only provides guidance and recommendations for material usage and it shouldnot be construed as mandatory requirements from the Building and Construction Authority. TheQualified Persons should ensure that the ensuing design and execution of his/her projects are inaccordance with the Authority’s requirements.Additional references should be made to the appropriate chapters in BS 5950 and SS EN 1993.ACKNOWLEDGEMENTThe Building and Construction Authority of Singapore (BCA) acknowledges the contribution ofA/Prof Chiew Sing-Ping of the School of Civil and Environmental Engineering, NanyangTechnological University for compiling this handbook for BCA.i
1.0INTRODUCTIONIn Singapore, the current approved design code for structural steel design is BS 5950. SS EN 1993is being phased in and will eventually replace BS 5950. Specifically, these design codes willspecify clearly the steel materials which can be used to design to these codes.This is a critical consideration as design codes are formulated taking into account the type ofmaterials manufactured to specific material production standards, in this case, it will be thosematerials manufactured to BS EN production standards. The implication of this is that buildersshould only procure such steel materials to comply fully with the design adopted by the QualifiedPerson (QP) and the building regulations. Strictly speaking, other steel materials manufactured tonon BS EN production standards cannot be used as they will be in conflict with the designrequirements.The Building and Construction Authority has taken steps to allow a wider choice of steel materialsto achieve greater economy and sustainability, and to promote greater usage of structural steel inthe building and construction industry. In the ensuing process, it will be necessary to ensureproduct conformity, quality and traceability in materials coming from various sources, and onlyadequate and reliable alternative materials are used to ensure public safety.In this connection, the design guide BC 1: 2012 was written specifically for this purpose and a listof certified materials manufactured to BS ENs as well as non BS EN materials such as ASTM,AS/NZS, JIS and GB are compiled for design to both BS 5950 and SS EN 1993 design codes. Thedesign guide also gives guidance on how to optimize the usage of such alternative materials, i.e. touse the full design strength for more competitive design if the certified materials can demonstrateadequately that they meet all the reliability requirements and qualify as Class 1 steel materials.This handbook serves as a complimentary publication to the design guide BC 1: 2012 and theprimary intention is to provide some background information and explain how to classify steel intothe different classes in BC 1: 2012. In addition, it provides the design parameters to be adopted forBS EN, ASTM, JIS, AS/NZS and GB steel materials as well as a list of certified and non-certifiedsteel materials.1
2.0DESIGN PROCEDUREBC 1: 2012 classified the certified steel material into Class 1, 2 and 3. The design approaches aredifferent based on this classification. This section explain in details the various design procedureswhich can be adopted during the design stage and the design implications based on therecommendations given in BC 1: 2012.The design procedure is first based on classifying the steel materials by means of adequacyassessment and reliability assessment into the appropriate classes. The classified steel materialsshall then be designed to BS5950 or SS EN 1993 based on the design requirements for thatmaterial class. The design flow chart is shown in Figure 2.1. A brief summary of the adequacyassessment and reliability assessment are given in Table 2.1.Adequacy AssessmentOption 1: CertificationSelect certified steel materials from Appendix A of BC 1: 2012DesignCalculationStageorOption 2: Material TestingEngage an accredited laboratory to conduct material testing in accordance to AppendixB of BC 1: 2012.

2.1ADEQUACY ASSESSMENTThe first step in the classification approach involves the verification of the steel material propertiesagainst the material performance requirements given in Section 2 of BC 1: 2012. Failure in theadequacy assessment shall result in the downgrade of the material class to Class 3. Two modes ofadequacy assessment are possible, either by certification or material testing. The differences in theimplementation these two modes of assessment and the respective results are given in Table 2.2.2.1.1CertificationCertification is the process of evaluating the material properties against the material performancerequirements in Section 2 of BC 1: 2012 for British/European, American, Japanese, Australian/NewZealand and Chinese material standards. Materials which meet these requirements are classifiedas certified steel, whereas those which do not meet the requirements are classified as non-certifiedsteel.A list of certified steel materials in which their material properties comply with the relevant materialperformance requirements is listed in Appendix A of BC 1: 2012. The use of any steel materialfrom this list of certified materials shall be considered as meeting the material performancerequirements given in Section 2 of BC 1: 2012 and satisfying the adequacy assessment.During the design stage, QPs shall select the steel material from the list of certified steel materials.The QPs shall then carry out the design and calculation using the design parametersrecommended in Section 5.1 of BC 1: 2012 for the steel material selected. It is assumed that thematerials will be sourced from manufacturers who can meet the quality assurance requirementsand this will have to be verified during material procurement and delivery stage.2.1.2Material TestingBasically, Material Testing is the process to demonstrate the adequacy of alternative steel otherthan those already considered in Section 2.1.1 through appropriate sample testing and test methodgiven in Appendix B of BC 1: 2012.Testing carried out for the purpose of adequacy assessment during the design stage shall notexempt the purchasers from performing the obligatory inspection and testing in accordance withappropriate regulations during contract execution stage.Test reports from accredited laboratories under the Singapore Laboratory Accreditation Scheme(SINGLAS) or other laboratories accredited under a mutual recognition agreement with SINGLASare required to prove that such materials are able to comply with all the material performancerequirements given in Section 2 of BC 1: 2012.When the limiting values are not given in Section 2 of BC 1: 2012, linear interpolation shall beallowed to determine the limiting value for the test parameters.During the design stage, if the QPs decided to select a non-certified steel material, the QPs shallengage an accredited laboratory to conduct material sample testing in accordance to Appendix Bof BC 1: 2012 and submit a test report containing the necessary information (see Table 2.3) toshow that the materials complies with all the material performance requirements given in Section 2of BC 1: 2012.3
For non-certified steel which meet the test requirements, the QPs shall carry out the design andcalculation using the design parameters recommended in Section 5.2 of BC 1: 2012. It is alsoassumed at this stage that the materials will be sourced from manufacturers who can meet thequality assurance requirements.CertificationBased on Section 2 of BC 1:2012InitiationQPs to initiate testingClass 1, if also pass thereliability assessmentAny material not listed inAppendix A of BC 1: 2012manufactured to materialstandards which are currentand confirmed, regardless ofthe country or region of originQPs to engage an accreditedlaboratory to conduct materialtesting in accordance toAppendix B of BC 1: 2012 andshow that the steel materialsare in compliance with all therelevant requirements given inSection 2 of BC 1: 2012Class 2, if also pass thereliability assessmentClass 3, and review designClass 3, and review designSteel materials coverageCertified steel materials, asgiven in Appendix A of BC 1:2012Condition to pass theassessmentQPs to select steel materialsfrom the list of certified steelmaterials given in Appendix Aof BC 1: 2012Class of material, if pass theassessmentClass of material, if fail theassessmentMaterial TestingTable 2.2: Implementation of Certification and Material TestingxxxxType of steel materialsSteel platesHot rolled sectionsHollow sectionsSteel for cold formingxxxxxxxxNon-preloaded boltingassembliesPreloaded bolting assembliesxxxxxxxWelding consumablesxxxxMandatory test resultsYield strengthTensile strengthElongation after fractureImpact energyChemical content based on ladle or product analysis, ofcarbon, sulphur, phosphorous, silicon, manganese, copper,chromium, molybdenum, nickel, aluminum, niobium,titanium, vanadium, nitrogen and any other elementintentionally addedCarbon equivalent value computed based on equation:%Mn %Cr %Mo %V %Cu %NiCEV(%) %C 6515Yield strength (bolts)Tensile strength (bolts)Elongation after fracture (bolts)Hardness (bolts, nuts and washers)Proof load stress (nuts)Chemical content, based on product analysis, of carbon,sulphur and phosphorous (bolts and nuts)Yield strengthTensile strengthElongation after fractureImpact energy4

The reliability assessment is toensure that the steel materials are manufactured under stringent quality assurance system andthat it shall meet the quality assurance requirements given in Section 3 of BC 1: 2012. Failure inthe reliability assessment shall result in the immediate downgrade of the material to Class 3.The implementation of reliability assessment shall involve the submission of valid factoryproduction control certificates and manufacturer test certificates. The differences in theimplementation of the reliability assessment are summarized in Table 2.4.2.2.1Factory Production Control CertificationThe manufacturers shall have a factory production control (FPC) system attested by anindependent third party certification agency acceptable to or recognized by BCA through initialinspection and subsequent continuous surveillance of the FPC system by the certification agencyat least once per year. Examples of these certification agencies includes, but not limited to;American Bureau of Shipping (ABS), American Petroleum Institute (API), Bureau Veritas (BV),Korean Register (KR), Lloyd’s Register, TÜV Rheinland, DNV GL, Société Générale deSurveillance (SGS) etc.Valid FPC certificates issued by the certification agency shall be produced by the manufacturers asan indicator of a FPC system acceptable to BCA.General requirements on FPC are given in Section 3.1 of BC 1: 2012. However, the following shallbe noted: ISO 9001 certificate for quality management system is complimentary. Having an ISO 9001certificate alone is regarded as insufficient to demonstrate reliability of the FPC system formanufacturers in a production environment. FPC certificates shall form the only acceptable indicator for an attested production controlsystem in manufacturing a particular type of steel materials. FPC certificates for BC1’s certified steel materials should clearly indicate the validity periodof 3 years in the certificates. FPC certificates for BS EN steel materials under the European Union ConstructionDirectives or API Monograms, both which are already widely recognized in the Europeanmarket and the oil and gas industry respectively, shall be considered ‘acceptable in lieu’.The FPC system of such manufacturers in manufacturing the particular type of steelmaterials shall be considered already attested.5
Upon confirmation of the source of the steel materials, QPs shall evaluate the validated copy of theFPC certificate, obtained either directly from the manufacturer or through the stockist or trader. TheFPC certificate shall also be made available for subsequent inspection by BCA, if required.Requirements to meetObjective ofassessmentCertificate to beproduced by themanufacturersValid coverage of thecertificateCondition to passassessmentClass of material, ifpass both assessmentClass of material, if failone of the assessmentFactory production control(FPC) certificationFactory production control, asgiven in 3.1 of BC 1: 2012The manufacturer of steelmaterialsA valid factory production control(FPC) certificate issued by acertification agency acceptable toor recognized by BCAManufacturer test certification(MTC)Manufacturer test certificates, asgiven in 3.2 of BC 1: 2012The steel materialsxxA sample test certificateAn authenticated testcertificate containingcomplete information forevery batch of steel materialsdeliveredThe production control and qualityQuality assurance on theassurance provided by theparticular batch of steel materialsmanufacturer in producing thedeliveredparticular type of steel materialsx QPs are to evaluate thesample certificate uponconfirmation of source ofQPs are to evaluate the certificatematerialsupon confirmation of source ofx QPs are to evaluate thematerialsactual certificate which shallalso specify the actualquantity of steel materialsdeliveredx Class 1, if pass the adequacy assessment by certificationx Class 2, if pass the adequacy assessment by material testingClass 3Table 2.4: Implementation of Factory Production Control Certification and ManufacturerTest Certification2.2.2Manufacturer Test CertificationThe manufacturer shall issue an authenticated test certificate for every batch of steel materials asa form of quality assurance on the steel materials delivered to site.Mandatory information on test results corresponding to different type of steel materials issummarized in Table 2.3.It shall be noted that the use of the test results of feedstock materials, if any, shall be clearlyindicated.
