25/00001-4 - Invitation to tender for helicopter airborne geophysical survey 2025.

The purpose of this process is to obtain competitive bids for the acquisition of a combined magnetic, electromagnetic (EM) and gamma-ray spectrometric data survey in Innlandet County, Norway as specified in the Scope of Services and Technical Specifications . Other areas with similar demographic and topographic challenges may be added if time and budget permit at the end of the survey flying of the current planned areas. No pre-qualification process will be required under this invitation to bid. The purpose of the procurement is to enter a four (4) years framework agreement for helicopter airborne services for acquisition of aeromagnetic, radiometric and electromagnetic data in Norway. For the next four (4) years, the Geological Survey of Norway intends for acquiring combined magnetic, electromagnetic (EM) and gamma-ray spectrometric data, from a helicopter type AS 350 B2 or similar, on an area of approximately 12,000 km2 or ca.60,000 line-km in Norway. The planned survey areas for 2025 will cover 3100 km2 or 15,300 line-km. Flying altitude will be 60 m ± 20 m except in densely populated areas where the clearance must be 100 ± 20 m. Re-flights shall be undertaken where terrain clearance deviates from that continuously for more than 3 km, except for where pilot’s decision is due to safety reasons. Not more than 10 % of each line is allowed to be outside this limit.
