j) Every working place shall be safe and of great dimensions. When tolls or material could fall 1.8meters of more, guardrails and toe boards shall be provided. Should the provision of these safeguard impracticable, other means of prevention such as SAFETY belts cradles, etc shall be used. 8.6.5 Guardrails and toe boards a) Guardrails and toe boards shall be fitted at edges of decking from which men or materials could fall a distance of more than 1.8 meters. Guardrails shall not be less than 920mm and not more than 1.15meters high and the space between toe boards and guardrails shall not exceed 760mm. b) Guardrails and toe boards shall be securely fixed to the inside of standards to prevent outward movement. 8.6.6 Access Access to a working platform is best achieved by providing a separate ladder tower or cantilevered access platform so as not to obstruct the platform and to minimize he possibility of persons falling through the gap in the guardrail or decking. 8.7 SYSTEM SCAFFOLDING System scaffolding, also known as unit frame, tubular welded frame, or patent scaffolding, is composed wholly or partly of prefabricated sections. There are many type of system scaffolding available which vary a great deal in design and methods of erection, however the same basic principles set out in 3.5 construction common to all scaffolds apply and the following matters require particular attentions. a) To be erected and dismantled by experienced workmen under the direction of a competent supervisor in accordance with manufacturer’s specification.

) Periodic inspection shall be executed of all parts and accessories. Broken, bent, altered, excessively rusted or otherwise structurally damaged frames of accessories shall not be used. c) Scaffold legs shall be pitched on steel base plates and on timber sole plates or as necessary. Adjustable base plates shall be used to compensate for variations in ground levels. d) Scaffolds shall be properly by cross braces or diagonal braces or both, and the cross braces shall be of such length as will automatically acquire and align vertical members so that the erected scaffold is always plumb, acquire, and right. All brace connection shall be made secure. 8.7.1 General purpose independent tied scaffold a) General requirements : General requirement for erection shall be in accordance with 35 construction common to all scaffolds. b) Design Loading and dimensions : A general purpose independent tied scaffold may have up to four working platforms in use at any time. The maximum distributed load on each platform shall not exceed 180Kg/cm2 and the standards shall not be more than 2.1 in apart longitudinally. Not more than one other platform may be boarded out for the purpose of erection, dismantling or access. c) Decking: The working platforms between standards should not be more than five boards wide (each board 200 mm wide) and it is permissible to place one of these boards between the inner standards and the building if space allows. (d ) Ledgers: Generally ledgers shall be vertically spaced at 1.8m to 2.1m centers o give adequate headroom along the platforms. The first pair of ledgers, however, may be up to a maximum height of 2.6m. (e) Limitations: General purpose independent tied scaffolds erected in accordance with the foregoing directions with not more than four working platforms, may be used up to a maximum height of 45m. General purpose independent tied scaffolds departing from these directions shall be specially designed. Pre-Qualification Document Khalid S. Al-Shahrani Est. Page 49
