Interested parties should hold a valid PEC Category C-4 or above license and be registered with the FBR with an active ATL status for the fiscal year 2025-26. Compliance with these requirements is crucial to avoid disqualification. The department advises verifying all documentation, including Earnest Money in the form of a Call Deposit Receipt (CDR), to meet tender conditions.

Bidders must submit sealed hard copies of their technical and financial bids separately.
