The plans for the three quarries shall distinguish two scenarios:
-
Scenario I: Rehabilitation after future complete exploitation of the quarries; thereby the Contractor shall only update the existing long term rehabilitation plans as per Annex A.1 of this contract (not required for Neszmely sand pit).
-
Scenario II: Rehabilitation based on present material reserve status, thus considering no further exploitation will be done (based on present condition described by topographical map)
-
All plans shall include full rehabilitation including but not limited to:
-
final surface slopes
-
proper long term surface water drainage system
-
access routes as necessary
-
proper waste-dump re-cultivation
-
proposed final surface conditions (vegetation, soil structure)
-
demolition and removal of all buildings, such as crushers, etc. in rehabilitation plan.
-
proper fauna and flora consideration based on surrounding conditions.
-
post-recultivation requirements (monitoring, etc.)
-
estimate for cost (+/- 10 %) and time for the actual execution as well as any postexecution requirements (e.g. monitoring, etc.). The estimate shall include a breakdown by activity and bill of quantity (BOQ)
