PREFACE This guide shall serve only as a quick guide to facilitate construction supervision for Resident Engineers (REs) and Resident Technical Officers (RTOs) . REs and RTOs MUST still refer to approved drawings, building specifications, codes, other relevant documents and relevant authorities’ requirements for the exact execution of the works. References are made to BC1: 2012 Design guide on use of alternative steel materials published by BCA. Technical Editor: A/Prof Er. Dr. Chiew Sing-Ping Nanyang Technological University Foreword by President, IES Dear Resident Engineer / Resident Technical Officer, The supervisory role that you play at the worksite is of paramount importance when it comes to safety and in ensuring the quality of the work. Most accidents at the worksite can be prevented if the site supervisors are more careful or alert to the process and procedures applied. Neglect and non-conformance to standards and guidelines were the two main factors that caused accidents. It is with this in mind that this Steelwork Supervision Guide for Qualified Site Supervisors is launched to provide guidance on the supervision of structural steel works at construction site in the areas of material, fabrication, erection, testing, corrosion, fire protection, as well as proper documentation, which is also an important area when handling structural steelworks at worksite, as the documentation will also ensure that the job has been done correctly. I hope that all Res / RTOs will make full use of the guidelines in this guidebook and apply them in the course of their work so that the workplace could be made safer. I would like to thank A/Prof Er. Dr Chiew Sing-Ping of National Technological University for editing this guidebook so as to provide easy understanding of the areas that site supervisors would need to pay attention to when supervising structural steel works at worksite. Er. Ho Siong Hin President , The Institution of Engineers, Singapore Foreword by President, ACES The importance of our QSS as part of our consultancy work cannot be underestimated in the Built Environment. We depend heavily on the professionalism of our QSS on the ground to help ensure that our designs are followed through on sites and the products delivered safely and according to specifications to our ultimate clients. In this regard I must commend the JAC for the superb work that they have contributed to these two sets of guide books

FAQs

What is the purpose and scope of the Steelworks Supervision Guide for QSS?

It provides guidance for supervising structural steelworks on construction sites, including material, fabrication, erection, testing, corrosion, fire protection, and the documentation needed to ensure correct execution.

What must QSS check for materials during factory inspection?

Materials must be new and supplied with manufacturer test certificate (MTC), produced under manufacturers with valid factory production control (FPC) certificates, and the tag/printing with heat numbers should match submitted manufacturer certificates.

How does the guide define quality and certification for structural steelworks?

It requires submission of a QA/QC manual (including fabrication and erection processes, inspection and testing plan, and lists of WPS and qualified welders). It also distinguishes class qualification based on whether valid FPC certificates exist and whether steel standards comply with referenced codes.
