What Excon does

Constructora Excon S.A. is a Chilean heavy civil construction and mining services contractor founded in 2005 and headquartered in Huechuraba, Santiago. The company specializes in large-scale earthmoving projects, mining operations, and civil works, with three founding partners who collectively bring more than 30 years of industry experience. Excon's core service portfolio includes earthmoving construction (representing more than 70% of direct costs on relevant projects), mining operations contracts, tailings dam construction and raising, evaporation pool construction for lithium extraction, general civil construction, and road works. The company operates a specialized heavy machinery fleet — excavators (30–120 tons), dump trucks (55–90T), bulldozers (D6–D9), wheel loaders (992), articulated trucks (40T), motor graders with laser technology, and Wirtgen equipment — that constitutes the technological backbone of the business.

The company generates revenue through fixed-price or unit-based construction contracts (priced per m3, ton, or machine-hour, with monthly fixed-rate alternatives) typically running 12–36 months, awarded via competitive bidding or direct negotiation. Its go-to-market is enterprise field sales targeting tier-1 mining companies; distribution is exclusively direct B2B with on-site delivery at client mining locations. Excon maintains ISO 9001:2015 certification (since July 2020) for civil works and mining services, plus ACHS Occupational Health and Safety Management System certification based on ILO guidelines, both of which serve as prequalification credentials for major mining tenders. Customer relationships span the dominant Andean mining majors — SQM, Codelco, TECK, BHP, Anglo American, Antofagasta Minerals, Collahuasi, Barrick, and Lumina Copper — with Bechtel as a key engineering/construction management partner on TECK QB2 and BHP projects.

Excon is privately held by its three founders with no disclosed institutional investors, subsidiaries, M&A, or external funding rounds. Operations span Chile, Peru, and Argentina, with international work concentrated in Argentine lithium (Cauchari for Minera Exar, Salar de Hombre Muerto for Galan Litio). The company executes larger projects through consortium arrangements — notably with Emex (BHP Escondida 8th raise, 500 personnel, 30 months from January 2025), Echeverría Izquierdo (Codelco Radomiro Tomic), and Huasi Construcciones (Galan Litio). Quantified project benchmarks include 43 million m3 moved at Caserones, 11+ million m3 at TECK QB2, nearly 9 million man-hours on a single project, and 35 million m2 of evaporation pools constructed for SQM.
