The CISC Code of Standard Practice for Structural Steel is a compilation of usual industry. practices relating to the design fabrication and erection of structural steel These practices. evolve over a period of time and are subject to change as improved methods replace those of. an earlier period The Code is revised whenever a suf cient number of changes have occurred. to warrant a new edition, The rst edition of the Code was adopted and published in November 1958 A second edition. incorporating minor revisions was published in October 1962 The third edition published. in September 1967 and revised in May 1970 incorporated minor changes throughout with. principal changes in Section 2 De nition of Structural Steel and Section 3 Computation of. Weights for Unit Price Bids, The fourth edition adopted in June 1980 revised December 1980 broadened the scope to in. clude bridges and other structures It also incorporated the CISC Guide to Tendering Proced. ures into Section 3 and Appendices B and C The Code was converted to SI metric units and. provided conversion factors and Imperial units in Appendix E. The fth edition 1991 re ected the steel standard s recognition of the preparation of ve types. of fabrication and erection documents which may be produced in ful lling a steel construc. tion contract These documents may be in the form of drawings diagrams sketches computer. output hand calculations and other data which can be supplied by the fabricator erector This. data is generally referred to in contract documents as shop drawings The computation of. mass has been changed by deleting the mass of welds and the allowances for paint and other. coatings Appendix B Guideline for Unit Price Application for Changes and Appendix C A. Suggested Format for Price Per Unit of Mass or Price Per Item Contracts were substantially. revised To foster uniformity two new appendices were added Miscellaneous Steel and A Sug. gested Format for a Monthly Progress Claim Form, The sixth edition 1999 clari ed the role of the fabricator the information required and where. that information is expected as stipulated in the governing technical standards Added were. de nitions of Design Drawings and Quotations clauses on quotations discrepancies shims. for bearing surfaces the allowance for return of documents the information required when. painting is speci ed and Appendix H Suggested De nitions for Progress Invoicing and Sub. stantial Performance Changes were also made to Appendix C the terminology for Unit Price. contracts connection types and anchor rods the latter two to be consistent with the changes. in CSA Standard CAN CSA S16 01, This seventh edition adds two new appendices I Architecturally Exposed Structural Steel. AESS and J Digital Modelling in order to give guidance to designers owners and contract. ors on these two important topics As each of these topics involves issues that vary widely and. approaches differ the Code endeavours to identify and clarify the main points that should be. addressed by the interested parties to avoid con icts during actual construction In addition. de nitions of AESS STEEL DETAILER and WORK and a time frame for accepting erected. steelwork have been added,7 6 CISC Code of Standard Practice. Whenever a gender speci c term is used it shall be read as gender neutral. By documenting standard practices the Code aims to promote a clear understanding between. the Canadian structural steel fabrication and erection industry and its clients.
