San Martín

What San Martín does

San Martín Contratistas Generales S.A. is a Peruvian mining and construction contractor founded in 1989 and headquartered in Lima, with operations in Peru, Colombia, and Spain. The company delivers two core service lines: Operación Minera (mining operations), encompassing full-cycle excavation, material handling, and on-site equipment management, and Construcción Minera (mining construction), covering civil works, assemblies, road construction, and massive earth movement. Its client base includes major Latin American and Spanish mining, cement, and infrastructure operators such as UNACEM, Hochschild Mining, Shougang Hierro Perú, Pacasmayo, Minsur, Argos, First Quantum Minerals, Riotinto, Compañía Minera Ares, and ADIF España.

The company operates a specialized fleet of more than 500 heavy equipment units (Caterpillar and Volvo machinery, including hybrid heavy machinery) deployed across client sites, and complements service revenue with a secondary Equipos en Venta (equipment resale) business channeled through its own website. Its technology stack is conventional heavy-civil and mining — earthworks, hybrid heavy equipment, and processes certified under OHSAS 18001 for occupational safety and ISO 37001:2016 for anti-bribery management — with no proprietary AI, software platform, or data flywheel disclosed in available materials. Pricing is project-based, quote-driven, and structured around multi-year contracts negotiated directly with enterprise clients.

San Martín's go-to-market is enterprise-direct and relationship-driven, anchored by 30+ year client relationships and consortium-based bids for mega-projects, including the ADIF Spain high-speed rail earthworks contract (2024, in consortium with GME) and the UNACEM Atocongo Stage I crusher project (2025, in consortium with HV Contratistas). The company is family-controlled by the Siucho Dextre family, with three family members serving on the Board of Directors alongside a professional management team led by General Manager Alfonso Brazzini Visconti. Recent strategic activity centers on consolidating the Spain infrastructure presence, deepening consortium partnerships, and renewing scope with existing cement and mining clients rather than on acquisitions, funding events, or product diversification.
