What Walsh does

Walsh Perú by SGS — Ingenieros y Científicos Consultores is a Lima-headquartered environmental and social consulting firm founded in 1994 that serves industrial and infrastructure clients across Peru. The firm operates with a multidisciplinary team of approximately 130 professionals and delivers 70-80 projects annually across mining, electricity, hydrocarbons, transportation, sanitation, telecommunications, and industrial sectors. Walsh holds more than 500 approved Environmental Management Instruments (IGAs) under Peru's SEIA regulatory framework, the largest such portfolio in the country, positioning it as the most established specialist in environmental and social compliance consulting in the Peruvian market.

The firm's service portfolio is organized around nine core pillars: environmental impact studies under the SEIA framework (EIA, EIA-sd, MEIA), enabling title management for environmental permits delivered through the proprietary IntegrAmbiente platform, baseline and socio-environmental monitoring studies, environmental monitoring and restoration, international-standard audits and due diligence (World Bank, IFC, IDB), mining engineering and mine closure, additional environmental services including satellite imagery and archaeological clearances, social services including community relations and conflict resolution, and hydrogeological studies. Walsh delivers these services via direct, project-based, multi-year consulting engagements managed by multidisciplinary teams at client sites and its Lima and Arequipa offices.

Since 2025, Walsh Perú has operated as a subsidiary of SGS, the Swiss-based global leader in Testing, Inspection and Certification, integrating the Peruvian practice into SGS's international TIC network. Revenue is generated through professional services fees quoted per project based on scope and complexity, with no publicly disclosed pricing. The firm maintains enterprise client relationships with major mining operators (Rio Tinto, Barrick, Antamina, Cerro Verde, Hochschild), electricity companies (Luz del Sur, ENEL, Duke Energy, Globeleq), hydrocarbons companies (Repsol, PetroTal, Petroperú, Pluspetrol), and infrastructure operators (Lima Airport Partners, PTAR Taboada). Strategic partnerships with GAC Chile, Walsh Ecuador, and Centex Instrumentación y Equipos extend regional and technical reach.
