Who we are
Andrieux & Associates Geomechanics Consulting, L.P. (A2GC) is a Montreal-based consulting firm established in 2015, which offers technical services in the fields of geomechanics, ground control, numerical modelling and drilling and blasting to local and international mining, construction and civil engineering clients.
Technical work is directed and supervised by Patrick Andrieux, a mining engineer with thirty-five years of experience at operating mine sites (both on surface and underground), as well as in research and development, instrumentation, technical services and support, training, and consulting. Patrick is also Adjunct Professor at Laval University in Quebec City, at the Department of Mining, Metallurgical and Materials Engineering.
Our goal and approach
Our purpose at A2GC is to provide our clients with the highest quality technical services in a timely and cost-effective manner, for the ultimate goal of efficiently solving complex geomechanical and blasting challenges.
A2GC can address a wide range of projects, from small to large. When required, it can rely on a network of hand-picked external associates, all world-class leaders in their line of work, and notably in the fields of structural characterisation, instrumentation, hydrogeology and civil engineering. This approach allows A2GC to offer a wide array of world-class technical services while maintaining a light structure, which, in turn, allows for lower hourly rates and, consequently, smaller overall project costs.
When projects do involve external participants, A2GC strives to streamline communications for the client, by sub-contracting, administrating, coordinating, supervising and reporting all aspects of the work.
What makes us unique
A2GC personnel combine over 17 years of working at operating mine sites with over 50 years of providing technical and consulting services to a wide range of clients. Having worked “on both sides of the fence” provides A2GC with a unparalleled perspective on its clients’ needs and expectations.
A2GC combines this experience with a thorough understanding of the mining business, whereby uncertainties, risks, costs, cycle times and delays are to be minimised, while productivity, production, and, ultimately, profits are to be maximised. A2GC recognises that, even though safety risks to personnel are never acceptable under any circumstance, some level of business risk may be allowable, based on the tolerance of the client.
A2GC personnel have extensive experience running and managing geomechanical, ground control and drilling & blasting technical projects, which allows for a tight fit to be maintained between the analyses undertaken and the objectives of the work, to efficiently zero-in on practical, doable and viable long-term solutions.
