General Guidelines For Civil Engineering Works

  • Electricals conductors shall not run through by column.
  • Earthwork work excavation for basement above 3m must be stepped form.
  • Any backfilling shall be compacted 95% of dry density at the optimum moisture content and in layers not more than 200 mm for filling above structures and 300 mm for no structures.
  • Soling stone shall be laid at 45degree to 60degree inclination¬† filled with sand and morum.
  • All reinforcement shall be free from mills scales, loose dust coats of paints ,oils or any other materials or substances.
  • Providing with proper cover blocks, spacers , chairs etc all reinforcement shall be placed and maintained in position as shown in structural drawing.
  • Cement shall be stored in a dry place on a raised platform about 200 mm and above floor level 300 mm away from walls .Not more than 10 no bags stacked in such a way that sufficiently protected from water , moisture content and any type of contamination.
  • Water which is used incase of curing and mixing must be clean and free from deleterious substances i.e oil, acid, alkalis, sugar ,salt, organic material and PH must be maintained between 6 to 8.
  • Initial setting time of cement shall not be less than 30 min.
  • Final setting time of cement shall not be more than 10 hrs.
  • Different samples from fresh concrete must be taken and at least a set of six cubes of 150mm shall be prepared and cured.
  • Compressive strength of cubes must be checked at 7 days and 28 days. If such result does not meet at satisfactory level then necessary steps required to be taken.
  • Any set cubes shall be tested for each 30m3 of concrete or casting.
  • Water cement ratio of different grade of concrete shall be maintained as per requirement and admixture shall be added as per mix design.
