Excel Modular Scaffolding (93D98) is the only known source of this material at this time. The proposed procurement contains an option to extend the contract period one or more times at the discretion of the government. The total duration (base plus option years) shall not exceed five (5) years. Any resulting contract will consist of a one-year base period and four, one-year option periods. Scaffolds is designed so that the structure and its components are capable of supporting, without failure, their own weight and at least 4 times the maximum intended load.Įvery Scaffold Design requires sizable amount of man days of structural Designer to prepare a new geometry of scaffold design and rehiring of STAAD Pro V8i software with 3 D analysis.The Defense Logistics Agency (DLA) Maritime Portsmouth Naval Shipyard intends to negotiate a firm fixed price requirements type contract for various components and quantities of Excel Scaffolding material as identified in the current Excel Modular Scaffold Standard Component Technical Manual, which is included as an attachment to this solicitation. The load acting on the each level will create stresses in all the members of the scaffolding and thus it all the case considered for analysis. The self weight of all the members is also considered for analysis. The detailed steel structure analysis is presented in the calculation part. The design method used for steel is Limit State Design (LSD). Load combinations are as per IS2750 - 1964 The wind loads are calculated and applied on respective equipment as uniformly distributed load in STAAD. Loads are categorized as Dead Load, Live Load, Wind Load (X, Z directions).The load calculation is presented on respective loading sheets. Any third party/ approval / cross check/ proof reading of scaffold design is to be obtained from Institute like IIT/NIIT or any other agency etc.Plot plan with respect to Equipment and Site location to know the space available for erection of scaffolding of Column.Type of scaffold materials like cup lock or pipe fittings or ring lock etc.To calculate Dead load of each platform/planks at every level, size of each platform is required.Give details of loading on every platform maximum uniformly distributed load as well as concentrated load on each respective platform.Loading philosophy to be followed based on actual job executed on this scaffolding. Consideration of Live load at all levels of scaffolding platform.Details of Equipment for which Scaffolding is to be designed, Duration of Scaffold to be kept on position, any special condition to be considered like factor of safety etc.Scaffolding design code (BS and EN standard) are useful for the preparation of preliminary calculation for the scaffolding design.Details of drawing, sketch, 3 dimensional view of the place where scaffolding work is to be carried out.Fixing arrangement of planks, toe board, ladder etc.Scaffold clamps fixed clamps, swivel clamps, Ladder clamps, Put log / any other clamps being used.of person and other dead load on the same Scaffold platform. For scaffolding components which are to be used for erection relevant details like physical dimension, weight of each component includes load test certificate of each component, other physical properties etc.This will include, Load, slip value, compression value, strut value, distortion value of each component, with Engineering drawing of each component Technical specification of each components of scaffold.Scaffold components play a vital role to design the Scaffolding System so technical details are required.Type of Scaffold/ Form work Materials to be used.Environmental data for the located site where scaffold is to be build.Basic Design document of client like scaffold standard/ procedure etc.Details of specific National / International Code of practice of Scaffolding to be followed for design.Basis of Design document covering uniformly distributed Load, Concentrated Load, Point load, accidental load etc.Strength, Stability and Rigidity of the structure is to be ensured for a safe erection/ use and dismantling of scaffolding.Īn Advanced Scaffolding Management System from ASK-EHS Engineering Consultants can facilitate the Project Management Team by providing an effective and efficient way to manage scaffolding System. When scaffold is to be erected at a height of 20.00 m and above or the scaffold is critical, may be hanging scaffold, a Structural Engineer involvement is must. ASK-EHS Engineering Consultants PVT LTD has emerged as one of the safe scaffolding solution provider in totality starting from design, inspection, and erection and dismantling of all new and ongoing scaffolding projects.
