Storm water, if it is present, must be diverted to another area so that it does not interrupt the progress of the work and also does not interfere with the final result of the work. Utmost attention must be paid to the backfill material to be used to fill up the spaces left behind by the excavations that have been made, for these materials that ensure that safety is maintained. (Division 2, Site work index)

Prior to backfilling the area, all debris must be removed, like for example, stones, rocks, any sharp objects, and so on. What must be remembered is the fact that a backfill, when improperly placed, have the result of inculcating a wedging action against the existing structures or the existing pipelines of the structure. Soil must be controlled, and compaction maintained, so that there will be minimum percentages of maximum density occurring throughout. If the area where the cable to be laid is under a lawn, then 6 inches of sub-grade soil must be compacted, and each layer of subsoil or backfill must be of a maximum density of 90%. If the cable is to be laid under a walkway, then the compaction must be of 6 inches of sub-grade, and each layer must be of the maximum density of 95%. Safety standards like those of the OSHA and the NC Department of labor must be strictly followed at all times so that the work being done would be of the best safety standards that are recommended.
In addition, when the backfilling under the streets and the walkways and under lawns and gardens is compacted according to the recommendations, the time to be allowed, generally three days, for the compaction to settle nicely must also be kept in mind. When all the pavement and concrete are patched up with the same material that was removed, then the result would be that it would not only conform to the safety regulations, but also be aesthetically pleasing to the eye. The public will be safe, and the standards would have been maintained. (Division 2, Site work index)
