The Eswatini Civil Aviation Authority has issued an international tender for the supply, delivery, installation, training, commissioning and flight check of a new Instrument Landing System at King Mswati III International Airport.
The procurement covers the replacement of the existing Instrument Landing System serving Runway 20, with the successful contractor required to deliver a complete Category I ILS package with ILS-DME and associated ancillary systems.
The scope includes the Localizer, Glide Path and ILS-DME systems, together with the required antennas, transmitters, monitoring equipment, power supply systems, cabling, equipment racks, shelters, grounding, lightning protection and surge protection. The system is required to be supplied as a complete dual-system, two-frequency installation, with remote control and monitoring capability.
ESWACAA has specified that the new ILS must support the airport’s existing operational requirements, including the current Localizer 20 frequency allocation of 111.5 MHz and the station identification “ISK”. Existing air traffic control procedures at King Mswati III International Airport are not expected to change as a result of the installation.
The contractor will also be responsible for dismantling and removing the existing ILS, carrying out the required site works, installing the new systems, completing commissioning, conducting site acceptance and reliability testing, and supporting the commissioning flight check.
The works also include the provision of new equipment shelters for the Localizer and Glide Path/ILS-DME systems. These shelters must include electrical systems, interior lighting, air-conditioning, battery shelves, grounding, lightning protection, intrusion detection and related operational fittings.
Power resilience forms part of the technical requirement, with the ILS central equipment required to operate from a DC power supply system in the event of a mains power failure. The overall power supply arrangement is required to support high system availability.
The successful bidder will also be required to provide spare parts, tools and test equipment, including a portable ILS signal analyser/receiver, frequency counter, RF test cables, extender boards, attenuators and ruggedised service notebook terminals.
Training is included in the contract scope. ESWACAA requires on-site facility training for 13 personnel over 10 days, factory training for four personnel and Factory Acceptance Testing before shipment. The contractor must also submit as-built drawings and plans once the installation has been completed.
The ILS is required to comply with ICAO Annex 10, Volume I requirements for Category I facilities. The project includes a one-year defect liability period and a two-year warranty period.
For King Mswati III International Airport, the procurement represents a full navigation systems replacement package, covering supply, installation, integration, training, flight checking and post-commissioning support.
