3. HEALTH  AND  SAFETY

• Strictly followed as per the manufacturer’s Health and Safety recommendations for handling and use of the materials.
• Ensure all involved personnel shall be aware of the same.
• Specific safety measures have to follow as applicable, and all the safety measures are covered separately in the project safety plan.

4. OPERATION

• Material: 
• Material used will be as approved by the Engineer.
• The sizes and routes routing will be as per the approved Shop Drawings.
• Storage and Protection: 
• Deliver components parts to site, completely identified in accordance with shop and certified CAD Drawings prepared for this work.
  
  
• Store in accordance with the manufacturer’s instructions, above ground, properly protected from the weather and construction activities.

5. INSTALLATION  and  fixation

• Pre-Installation:
  • All materials and documentation relevant to this particular section of works will be checked and verified ensuring that  these are correct and approved type.

• Prior to the commencement of works, ensure that the areas for permanent installation are ready, accessible and in suitable condition.

• Installation:
  • No conduit smaller than 20mm in diameter or larger than 32mm diameter shall be used.
  • Where a terminal block to be accommodated in the circuit box an extension ring shall be provided.
  • Draw-in conduit boxes shall be incorporated at intervals not exceeding:
    • Straight run – 10 m.
    • Run with four bends – 2.5 m.
    • Run with three bends – 5 m.
    • Run with one or two bends – 10 m.
  • Conduits, which are more than slightly damaged, shall be rejected. Conduits in floors shall be routed and installed so as to avoid the fixings of floor standing equipment to be installed on the floor.
  • All joints in PVC conduits, other than screwed joints, shall be cemented with a waterproof adhesive. This adhesive shall be as recommended by the conduit manufacturer.
  • Screwed connections between steel conduits and accessories shall be screwed up tight , where coupled by a socket the conduit ends shall butt together; running joints shall be provided with back nuts which shall be screwed up tight.
  • PVC conduit shall be saddled at a minimum of 1 meter intervals. All saddles, tubes and boxes must be in perfect alignment to avoid any appearance of warping when the installation is complete. Saddles should not be so tight as to prevent expansion of the conduit.
  • Steel conduits run on the surface shall be secured with galvanized saddles spaced not mores than 2 meters apart, on the other hand, a space bar type saddles will NOT be permitted.
  • Conduits shall not be run closer than 0.15m to any steam or hot water pipes and shall be run underneath such pipes rather than over them. It should not also be run closer than 0.05m to any telephone, bell or other signaling circuit.
  • No wiring or draw-in wires, cables or wire of any description are to be drawn into the conduits until the section of the conduit system involved is complete.
  • Drawn-in boxes must be provided to give access to all conduit for the drawing-in or out of any cable after the installation is completed.
  • Particular care shall be taken to ensure that no grout or other foreign materials enters the conduit system through joints, or through surface openings. Screw holes in boxes must kept entirely free and clean. After screeding, a compressed air is to be blown through the conduit system to ensure that it is clean and a steel draw wire of adequate size to be pulled through to a certain that no obstructions is adhering to the inside of the conduits.

• Commissioning:
  • When conduits are run on shuttering, prior to the laying of concrete insitu, additional security must be provided near to every box and at intervals of not more than 1.2 meters by binding short lengths of steel wire, of not less than 2mm diameter twisted around the conduit and reinforcing steel. The conduits shall be adequately fixed to prevent excessive movement and damage during the pouring and setting of concrete and shall be protected from mechanical damage. Check there is no damage before screed / concrete is poured. Unless otherwise indicated to cast in conduits shall not be less than 30mm.cores to plastered over conduits shall not be less than 5mm.
    
    
  • Where conduits are left “open ended” prior to wiring they shall be protected by caps or plugs to prevent the ingress of building material.
    
    
  • All conduits runs must be designed to permit wiring to be readily installed after the complete erection of the conduits through the available draw-in, accessory and luminary suspension boxes.
    
    
  • Where surface mounted equipment (other than luminaries) is specified, all concealed conduits shall be terminated and an adaptable box installed recessed into the wall at every surface mounted equipment position.

• Where conduits pass through an external wall/roof the conduit box shall be fitted on the side and after wiring filled with an inert, permanently plastic compound having a high insulation value.

• Make provision in conduit and trunking, installation where building expansion joints are crossed or settlement is likely

• Ensure conduits are not concealed until works has been inspected and approved. Ensure that conduit and fittings buried in concrete or behind plaster are protected against corrosion or electrolytic action prior to rendering.

• Technical Assistance:
• The installation supervising technician for the system trade shall instruct the CONSULTANT Engineer, and Construction Site Manager on the programming and correct operation of the system after the installation is completed.
• This instruction shall be scheduled at the convenience of the staff.
• All such instruction shall be properly recorded.
• WIR will be issued for Consultant approval upon making sure that the installation of the system equipment’s done as per approved shopdrawings and specs and manufacturer recommendations.
