Tierra Group is a multinational engineering design and consulting engineering firm known worldwide for its expertise in civil, geotechnical and water resource engineering, specialized in the mining industry.
This strategic integration will expand BBA’s presence across North and South America, with the addition of offices in Denver, Colorado; Elko, Nevada; and Lima, Peru. Through this partnership, Tierra Group will gain access to the Canadian market with the support of BBA’s network of 1,600 professionals. BBA will be welcoming 50 Tierra Group experts, whose internationally recognized tailings and heap leach design expertise has been applied across six continents.
“This is a significant moment for BBA. Building on our existing footprint in Chile and the United States, this agreement will expand our reach and strengthen our mining services across the U.S. and South America. With Tierra’s deep technical expertise complementing BBA’s multidisciplinary approach, we’ll be even better equipped to deliver robust, sustainable and regulation-aligned solutions that meet our clients’ evolving needs and drive long-term results,” says Jérôme Pelletier, CEO at BBA.
We’re also pleased to announce that Tierra’s founding partners—Matt Fuller, Pete E. Kowalewski and Julio Juarez—will be joining BBA after the transaction closes. These three respected leaders bring decades of technical and operational experience in the mining industry, along with strong client relationships around the world. Their continued involvement will be key to ensuring a smooth transition and maintaining the high level of service and expertise Tierra Group is known for.
“Joining forces with BBA is an exciting step forward for the Tierra Group team and our clients. We share a strong commitment to delivering high-caliber engineering solutions tailored to the mining sector’s evolving needs. Together, we’ll be expanding our reach and enhancing our ability to support the energy and natural resources industry on a global scale,” says Matt Fuller, Founding Principal, Tierra Group.
Looking ahead, both teams remain focused on providing high-value, client-centered engineering services that drive innovation and operational success.
The transaction is expected to close by July 2025, subject to customary closing conditions.
