    Brief

    Aarhus Universitet has entered into an agreement with Xcalibur Multiphysics South Africa for the provision of an airborne geophysical survey of the Rift Valley Basin in Ethiopia. The services involve using a helicopter-based slung-load transient electromagnetic (TEM) system and magnetic instruments to map shallow and deep hydrogeological structures, with the aim of imaging layers as thin as 3 meters near the surface and achieving penetration depths of up to 500 meters. The contract has a maximum value of 5,000,000 DKK. Only one bid was received for this contract.

    From the notice

    • Aarhus University seeks a contractor to carry out a large-scale airborne geophysical survey of the Rift Valley Basin in Ethiopia in early 2026, using a helicopter-based slung-load transient electromagnetic (TEM) system and magnetic instruments to map shallow and deep hydrogeological structures. Conducted in close partnership with the Ministry of Water and Energy of Ethiopia and Addis Ababa University, the survey aims to improve understanding of the Basin’s hydrogeological settings under different geological and environmental conditions. The contractor must collect high-resolution TEM and magnetic data, capable of imaging layers as thin as 3 meters near the surface and achieving penetration depths of up to 500 meters, while meeting strict technical, calibration, safety, and data-delivery requirements. The project includes joint flight-line planning, rigorous system testing and documentation, and delivery of data ready for processing in Aarhus Workbench, all within a maximum budget of 5,000,000 DKK.Main features of the procedureThe call for tenders is held as a public tender procedure in accordance with section 56 of the Danish Public Procurement Act (Act no.1564 of 15/12/2015), which means that all interested Tenderers have the opportunity to submit bids in response to this call for tenders.
