FAQ
What approvals do drilling companies need for public contracts? Typically required: evidence of mining-authority approvals, expertise under the DVGW code (water drilling), safety certifications and experience evidence for comparable deep-drilling projects.
Where do I find public tenders for drilling work? On TED under CPV 45255000 and 45255110 and on national procurement platforms. Geothermal projects are frequently tendered by municipal energy utilities.
