The scope of the project:
The scope of this project also includes various base-wide upgrades to the Bagram drainage infrastructure and various infrastructure installations at the Westside utility connections and Eastside expansion area. The construction of the drainage system was sub-divided into sections (phases) which are Project Area 3-4, Project Area 3-7, Project Area 3-8, Project Area 3-9, Project Area 3-13, Project Area 3-14 and Project Area 2-2.
3 of those sections were closed drainage system with piping, 2 of them contained both open and close drainage system, and the remaining sections only had open drainage system.
For close drainage systems, ground was being shored before the excavation in order to prevent any unexpected ground subsidence. After excavation, the ground had been prepared for pipes. Then, various sized pipes had been installed. Catch basins and manholes had been constructed, followed by backfilling and site drainage. Open drainage systems had smoother process than close systems which included excavation, compaction & grading, GCABC, Geotextile, Bedding and Grouted Stone activities.
