3 Introduction INTRODUCTION TO AT-PAC Since 1995, AT-PAC has offered Complete Scaffolding Solutions to our strategic clients throughout the world, matching our expertise to the specific needs of our Customers. With our extensive experience in the industrial market, we specialise in Oil, Gas & Chemicals, Power & Energy and Mining & Refining projects. AT-PAC hires and sells the highest quality products by ensuring that our production processes adhere to our rigorous quality assurance program and quality control. AT-PAC has locations throughout the UK, USA, Canada, Australia and South America. We currently supply Asia-Pacific, Africa, the Middle East and beyond. Our unparalleled expertise and professionalism enables us to consistently deliver Complete Scaffolding Solutions. Our experienced customer driven team provides a seamless service from product development, supply chain management, production, quality control, delivery with local engineering support available for fast effective solutions where required. AT-PAC Ring System is a modular system scaffold which has been combined with alternative similar components. When RINGLOCK components have been used together with components of a compatible system, all safe working loads in the following tables have been limited to the system with the lowest capacity. This enables users to quickly and efficiently erect, use and dismantle temporary work structures. The AT-PAC Ring System system conforms to European standards BS EN12810 and BS EN AT-PAC Ring System is compliant with The National Access & Scaffolding Confederation (NASC) Code of Practice for System Scaffold. This hire document is for Ringlock combined with alternative compatible components. AT-PAC LTD. is a Non-Contracting Full Member of the National Access & Scaffolding Confederation ISO 9001 Registered ISO Registered OHSAS Registered For more information please consult your local AT-PAC representative.

4 Ring System Quality Factors & Designation QUALITY FACTORS All of AT-PAC Euro range of Ring System products are engineered to meet the highest quality standards based on three simple factors: MATERIAL FIT FINISH We only use the highest quality steel in our products. Our steel is certified and tested, it conforms to or exceeds industry standards no matter the location or climate. AT-PAC products are engineered with versatility and usability in mind. Our modified product designs increase efficiencies and productivity, saving your projects time and money. Where applicable, our products are finished and protected by hotdipped zinc galvanising. This method of finishing maximises the utilisation and extends the product life. DESIGNATION OF The Designation of Ring System in accordance with BS EN :2003 is: Scaffold EN D SW109/307 H1 B LS Service Load Class 4 may be extended from Service Load Class 1 to Service Load Class 6 if required although there are restriction on bay length for Service Load Classes 5 and 6. This Technical Manual only considers Service Load Class 1 to Class 4 as the general loading required of a system scaffold under normal circumstances. Service Load Class 4: The following combinations of platform width and bay length are also available: SW06/73 to SW12/307 Cladding: Maximum permissible heights and tie patterns are given for both unsheeted, debris netted and sheeted scaffolds. All designations for Ring System Scaffold are on the Ring System Scaffold Designation Certificate of Compliance included at the rear of this document. 4 Copyright 2017 Atlantic Pacific Equipment.

16 Design Matrix DESIGN MATRIX FOR SYSTEM SCAFFOLD CATEGORIES Users of Ring System may find the following Design Matrix useful when assessing whether full Design or Technical Advice is required. The minimum requirements of information available to the Company management are split into three main categories and the following procedural notes and Design Matrix may be used to prepare the Method Statement and Risk Assessment for your project. CATEGORY 3 INFORMAL DESIGN TECHNICAL ADVICE NOT REQUIRED Refer to the Design Matrix for scaffolds that fall into this category. Scaffolds should be erected to comply with AT-PAC User Guide and the Work at Height Regulations, other current legislation, BS EN and where necessary TG20 (Latest Edition). Requirements for tying the scaffold to the permanent works, and the associated tying patterns are also included in this Ring System Technical Manual. Method Statements and Risk Assessments may be written using all data held here. CATEGORY 2 ESTIMATOR/SUPERVISOR DESIGNED SCAFFOLD TECHNICAL ADVICE REQUIRED If your own Design Department or Consultant is unable to assist, advice may be sought from AT-PAC UK Engineering team and this may be given verbally or be presented in the form of engineering solution advice or confirmation. Method Statements and Risk Assessments may be made using all data held in this Ring System Technical Manual. CATEGORY 1 ENGINEERED DESIGNED SCAFFOLD ENGINEERING DESIGN MANDATORY This category of scaffold requires your Design Department or Consultant to prepare a design and/or layout details using the technical information contained in this Technical Manual. All technical information held in this Guide has been independently tested and analysed in accordance with BS EN and BS EN We would recommend that a scaffold is not erected to a Preliminary Drawing because not all of the design may be complete and failure of the structure could arise in these circumstances. You should seek confirmation from your Design Department or Consultant. 16 Copyright 2017 Atlantic Pacific Equipment. All rights reserved. AP-UK-010-V3

18 Stabilising Scaffolds, Tying & Bracing Patterns METHODS OF STABILISING SCAFFOLDS Where the height of a scaffold will exceed three times the smallest lateral base dimension, the scaffold may be stabilised by: 1. Attachment to a building or structure by means of ties; or 2. If the scaffold is not more than three lifts high then raker s can be introduced in accordance with TG20 (latest edition). 3. Increasing the base dimension of the scaffold by buttressing with reference to TG20 (latest edition) to consider Height to Least Base dimensions before setting out the scaffold. Also, if necessary consult your local AT-PAC Engineering Office for advice. Please refer to the following Tie Patterns and Maximum Permissible Height Tables. TYING AND BRACING PATTERNS The following tying and bracing patterns cover 2.0m lift heights with 2 typical bracing patterns. The maximum height of the scaffold is dependent on the BS EN Load Class rating used. Other factors such as the S Factor, cantilever requirement and Debris Netting/ Clad requirements. For example: A 2.0m lift using tie pattern B, Load Class 1, no inside cantilever platforms or cladding the scaffold can be erected up to 80m with an S-Factor of 20. Note 1: Transoms and Ledgers must be placed in the lowest possible rosette irrespective of lowest platform position. Note 2: Completed scaffolds must always be tied at the top lift. Note 3: Up to two levels of cantilever platforms may be moved to intermediate levels at any one time to provide appropriate access. 18 Copyright 2017 Atlantic Pacific Equipment. All rights reserved.
