The backfilling and the associated steel grills and crash rated bollards may be removed from the scope of work of IC as it is necessary that the contractor working on construction of culverts for flood control channel completes this activity to work on associated works. IC is urged to provide an estimate of the quantities reflecting the following;
1. Backfilling works between the two colverts
2. Backfilling works for the guard house
3. Any other related works to complete all necessary activities in the flood control and culverts area which are in the scope of work or are to be excluded from the scope of work of the Kaust perimter security systems project.
