SADIM

What SADIM does

SADIM (Sociedad Asturiana de Diversificación Minera S.A., S.M.E., M.P.), operating commercially as SADIM Ingeniería, is a Spanish state-owned engineering and consulting firm headquartered in Langreo, Asturias, with 11-50 employees. Founded in April 1999 as a spin-off from HUNOSA (Hulleras del Norte, S.A.) to diversify the Asturian coal-mining economy, the company operates as a wholly-owned subsidiary within the SEPI (Sociedad Estatal de Participaciones Industriales) state holding group, which encompasses approximately 80,000 professionals across 16 directly controlled public companies.

SADIM delivers three core service lines: (1) Ingeniería (Engineering) covering consulting, technical assistance, project design, and construction management across mining engineering, civil engineering, environmental services, and museum/museography projects; (2) ATEX (Atmósferas Explosivas) providing consulting, inspection, training, and turnkey projects in explosive atmospheres and industrial safety; and (3) Medio Propio (Own Means) executing projects in mining restoration, territorial revaluation, promotion, and circular economy initiatives on behalf of public administrations. Underpinning these services are three proprietary software tools—HUNDEF for mining subsidence and deformation calculation, MINERISKS for environmental risk management of mining installations, and Gestor Documental FAMA for ISO 14001/EMAS document management. SADIM holds ISO 9001 (Quality) and ISO 14001 (Environmental) certifications, supports Geographic Information Systems (GIS) for environmental information treatment, and serves a customer base spanning Spanish public administrations (including SEPI group entities), major mining companies (Iberpotash, ArcelorMittal, Matsa, Lundin Mining, Ormonde Mining, Mayasa), energy firms (Endesa), and research institutions (Universidad de Oviedo).

The company's business model is dual-track. As a "Medio Propio" entity under Article 33 of Spain's Public Sector Contracts Law, SADIM receives mandatory direct commissions from SEPI group entities and other public administrations without competitive tendering—this is a structural revenue mechanism for environmental restoration, mining closure, and biomass projects. For private-sector work, SADIM competes in public tenders via the Plataforma de Contratación del Estado and pursues direct engagement with mining and industrial clients through professional networks. Pricing is project-based and negotiated per engagement; no public pricing data exists. Under HUNOSA's 2025-2028 Business Plan, SADIM is slated to become an explicit direct procurement entity for public administrations and the SEPI group, with combined investments exceeding 130 million euros and 160 new hires planned across the parent company and SADIM, signaling a deliberate scaling of the firm's role within Spain's state-owned industrial ecosystem.

Core offering

SADIM provides professional engineering consulting, technical assistance, project design, and construction management services across mining engineering, civil engineering, and environmental restoration. Its portfolio covers ATEX (explosive atmospheres) consulting, inspection, training, and turnkey industrial-safety projects. As a Medio Propio (proprietary means) entity, SADIM also executes mining, restoration, and territory-regeneration projects for public administrations, complemented by specialized museology and museography services for mining heritage and museum projects.

Product overview

SADIM offers a portfolio of three main service lines: (1) Ingeniería (Engineering) covering mining engineering, civil engineering, environmental consulting, and museum services including museology and museography; (2) ATEX (Atmósferas Explosivas) providing consulting, inspection, training, and turnkey projects for explosive atmospheres and industrial safety; and (3) Medio Propio (Own Means) delivering projects and works for mining, restoration, and territory regeneration as a direct procurement entity for public administrations. Additionally, SADIM has developed specialized software tools including HUNDEF for mining subsidence calculation, Minerisks-environment for environmental risk management, and Gestor Documental FAMA for document management.
