This procurement focuses on expanding the existing wireless infrastructure to Hyderabad and Sukkur regions, ensuring seamless, real-time communication between ambulances, dispatchers, and control centers. The project includes installation of radios with GPS tracking, base stations, communication towers, and repeater systems to cover urban and remote areas effectively. The scope demands technical compatibility with the Phase 1 infrastructure in Karachi, requiring rugged, IP54-rated radios compliant with DMR Tier II/III standards. Vendors must provide installation, maintenance, quarterly inspections, and a one-year warranty with advance replacement services. The communication towers are designed to withstand local wind and seismic conditions, ensuring reliable operation. This system is critical for uninterrupted ambulance dispatch during emergencies, especially in flood-prone and disaster-affected zones where cellular networks may fail. Bidders should be registered on the FBR and SRB active taxpayer lists and comply with PEC and SPPRA rules. The tender requires a refundable bid security of PKR 414,000 and a non-refundable tender fee of PKR 3,000.

Pro-Tip: Ensure your bid includes the correct pay order and bid security documents before the deadline, and verify your company's active taxpayer status on FBR and SRB portals to avoid disqualification. Also, carefully review the technical compatibility requirements to align with existing infrastructure and avoid common pitfalls in documentation completeness.
