Common use of General Design Requirements Clause in Contracts

General Design Requirements. All plant and equipment shall be suitable for operation under the design ambient conditions as detailed in Section 2.0. The Contract Works shall be designed to facilitate inspection, cleaning and repairs, and for the operation in which continuity of service is the first consideration. All apparatus shall be designed to ensure satisfactory operation under such sudden variations of load and voltage as may be met with under working conditions on the system and short-circuits, within the rating of the apparatus. The design shall incorporate every reasonable precaution and provision of the safety of all those concerned in the operation and maintenance of the Contract Xxxxx.Xxxxxxxxx shall be designed for reliable operation and ease of maintenance. All material used shall be new and of the best quality and of the class most suitable for working under the conditions specified and shall withstand the variations of temperature and atmospheric conditions arising under working conditions without distortion or deterioration or the setting up of undue stresses in any part. No welding, filling or plugging of defective parts will be permitted without the sanction in writing of the Engineer. All components shall be new and shall be manufactured from sound materials, completely free from all visible imperfections such as cracks, flaws, blow holes, etc. No castings, forgings or other material will be accepted in a condition known to be faulty. Corresponding parts liable to renewal shall be interchangeable. When required by the Engineer, the Contractor shall demonstrate this quality. All apparatus shall operate without undue vibration and with the least practicable amount of noise. Cast iron shall not be used for xxxxxxxx of fluid-filled apparatus or for any part of the equipment which is in tension or subject to impact stresses except where it can be shown that service experience has been satisfactory with the grade of cast iron and the duty proposed. Operating boxes, kiosks, cubicles and similar enclosed compartments forming part of auxiliary equipment shall be adequately ventilated to restrict condensation. All Contactor or relay coils and other parts shall be suitably protected against corrosion. Anti-condensation heaters of an approved type shall be provided inside each cubicle or where necessary each cubicle compartment. They shall be shrouded and located so as not to cause injury to personnel or damage to equipment. The thermostat shall be arranged to switch off the heater supply when the ambient temperature exceeds 30-35°C. Means shall be provided at each unit for isolating the supply. A common switch with a lamp labelled "Cubicle heaters on" shall be mounted at a convenient point such that it will not require movement in the event of extension units being added. All outdoor apparatus, including bushing insulators and fittings, shall be so designed as to avoid pockets in which water can collect. The underside of all relevant tanks shall be ventilated in an approved manner to prevent corrosion. All mechanisms shall, where necessary, be constructed of stainless steel, brass or gunmetal, to prevent sticking due to rust or corrosion. All electrical connections and contact shall be of ample section and surface for carrying continuously the specified currents without undue heating, and shall be secured by bolts or set screws of ample size, fitted with locking devices of approved type and material. All taper pins used in any mechanism shall be of the split type. All rubbing or wearing surfaces shall be machine surfaced. Joints employing a gasket material shall be so constructed that the packing is maintained under sufficient compression in all parts, so that an efficient joint can be made without the use of jointing compounds. Gasket material shall be of the minimum thickness necessary and of approved composition. All apparatus shall be designed to obviate the risk of accidental short circuit due to animals, birds and vermin. Openings in ventilated enclosures shall be so constructed to prevent the entry of vermin and insects.
