  4. Adequate water supply to the facilities preferably borehole
  5. Qualified supervising Engineer (Civil or Structural Engineer)
  6. Experience Welder/Iron bender in additional to other production personnel
  7. Adequate mechanical working tools
  8. A well testing rig with associated pull winch and a good dial gauge of at least 2500KN/kg range
  9. For circular/spun and pre-stressed types, the right equipment and facilities must be available on factory or production sites
  10. Curing ponds of appropriate size capable of handling 10& 15 No. poles at a time
  11. Means of lifting poles to and out of curing ponds
  12. All manufactured electric concrete poles shall have engraved on them: planting depth mark, date of manufacturing and initials of the manufacturing company
