Engineering-Driven Mining Solutions That Deliver Precision and Performance

GMS is more than a contractor — we’re an engineering-led partner with deep expertise in mine design, ground control, mechanical systems, and infrastructure support. Our in-house team of civil, mechanical, and mining engineers provides technical leadership on every project, ensuring precision, compliance, and quality from concept through completion.

From conveyor system design and ventilation planning to structural steel fabrication and site-specific ground control strategies, our engineering services are tightly integrated with our field operations. Whether supporting a new development or optimizing an existing site, we deliver custom, practical solutions that improve safety, productivity, and long-term value.

Our Engineering Capabilities

  • Mining engineering and site planning
  • Civil and structural design
  • Mechanical systems and custom machinery
  • Ground control and roof support design
  • Ventilation system layout and airflow modeling
  • Conveyor and belt terminal engineering

Every project begins with a technical plan — and GMS engineers are involved from the start. We design with the realities of mining in mind, tailoring every solution to the geologic, spatial, and operational needs of the site.

Integrated Project Support

  • Design-build capabilities
  • Engineering support for GMS field teams
  • Seamless coordination between design, fabrication, and install
  • Cost control and schedule optimization

What sets GMS apart is our ability to integrate engineering with execution. Our engineers work closely with our crews in the field — closing the gap between design and build, and keeping projects on time, on budget, and built to spec.

Custom Fabrication & Design

Custom Fabrication & Design

  • Computer-modeled square sets, arches, and tunnel rings
  • Specialty doors, support frames, and structural steel
  • Custom hauling and ventilation equipment
  • Designs built in-house at GMS fabrication facilities

We don’t just design — we build. GMS offers complete custom fabrication services to bring engineering concepts to life. Every component is designed for the rigors of mining and tailored to site-specific requirements.

What Sets Us Apart

Why GMS Engineering Brings More Than Just Plans to the Table

  • Industry-focused design: Solutions built specifically for the challenges of underground and surface mining.
  • Multidisciplinary expertise: Civil, mechanical, and mining engineers collaborate for smarter outcomes.
  • Hands-on coordination: Direct integration with our field crews ensures smooth implementation.
  • Built-in fabrication: Our in-house shops fabricate custom steel components and support systems.
  • Full-project alignment: From concept to installation, we streamline the entire design-build process.
What They’re Saying
  • I would like to express my appreciation to the GMS maintenance team. We are pleased and we commend them on their performance and professionalism. Finding and retaining trained mill wrights and process electricians has proven to be a challenge. From day one, GMS has been a positive addition to our maintenance department and has made it possible for the Nevada Copper Process Maintenance and Operations teams to start moving forward to achieve the goals we have set to operate and maintain a world class copper processing facility. Again, thank you, we are looking forward to continuing to work with the GMS team.

  • We at Normet Americas have worked with GMS Mine Repair and Maintenance for at least 12 years. GMS has used our shotcrete equipment, grouts, concrete additives, and void fill & rock reinforcement chemicals on many underground projects over the years. Our technical specialists have worked side-by-side with GMS personnel and can attest to their knowledge of concrete, shotcrete/grout mix designs and shotcrete spraying skills (including overhead). Safety and timely delivery of projects are their priorities.

  • GMS was contracted to perform resin grouting services to address water ingress into underground openings. During a planned inspection, engineering identified a discontinuity in the rockmass which required immediate attention. After thorough evaluation, we proceeded with a polyurethane injection to stabilize the rock mass. GMS executed the work safely, efficiently, and with precision, playing a key role in securing both the area and access, ensuring the continued safety and functionality of the mine.

  • I have been working with employees provided to me through GMS on different projects for over a year now. Most recently I have two electricians and a mining engineer on staff through GMS. The electricians are top notch I have one of the GMS electricians working as my lead electrician directing and overseeing our major power upgrade project that we are working on and could not be more pleased. And the young man that GMS provided us as a mining engineer is also fitting in and working out very well. I have been very happy with the personnel that has been sent to me through GMS. I highly recommend the use of GMS for anyone that is look for some short-term help or help getting staffed up for the long haul. Again, I have been nothing but pleased with the personnel I have obtained through GMS, and it takes a very big load off my shoulders searching for and hiring personal on my own.
