About Us

Who We Are

5D Mining & Construction, Inc. began as a spin-off from Dalmolin Excavating Corp in 2000, and over these past years has grown into one of the most respected contractors in the Copper Corridor area of Arizona. Throughout 5D’s history, we have moved dirt, poured concrete, welded pipe, erected steel, installed equipment, and maintained our clients’ facilities.

What We Do

We are a full service general contractor holding licenses in Arizona and New Mexico. Apart from electrical/instrumentation work, we manage and self-perform all aspects of our projects. Our management staff have over 100 years of combined experience performing the following types of projects:

  • Earthmoving: mass excavation, fine grading, backfill, storm water, or finish work
  • Concrete: flat work, foundations, walls, structures, and shotcrete
  • HDPE Pipe: Fusing and installation from 2” to 36”
  • Structural Steel: build new structures, repair existing structures, or modify old structures
  • Mechanical: piping, gas handling duct, setting equipment, stainless steel, carbon, or special alloys
  • Maintenance: shutdowns, normal day-to-day work, leach pads, water evaporation ponds, convertors, ball mills, and everything else in between
  • Capital Project: anode scale, convertor gas handling, tailings lines, and booster stations are just some examples

Our Values

Strong family values—honesty, integrity and accountability—provide the foundation for our company’s business principles. These core values are a fundamental part of our history, our current business philosophy, and our future. It is our commitment to work with the highest ethical, business and safety standards as a company, and to ensure that every individual who works for and with us does the same. We are committed to being the best general contractor in the Copper Corridor.


We conduct our business and personal affairs with the highest levels of integrity. We take responsibility and accountability for all our words and actions. We are honest, straightforward and deal fairly with everyone—no exceptions!

We honor our commitments to business partners, clients, suppliers and subcontractors as a part of our corporate integrity. Compliance with laws, rules and regulations, Federal government requirements and other agency requirements is the only way to conduct business at 5D Mining.


Building a trusting relationship with our clients requires clear expectations, shared goals, clarity of communication, professionalism, and mutual respect. We are consistently focused on high quality and safe production, and we build our work right the first time; delivering, with pride, the highest value to our clients. We measure our success by the positive reputation we have established.


Our employees are not only empowered, but are compelled to speak to an unsafe or unhealthy work practice or condition, which means our employees and subcontractors will return home to their families each night, absent a workplace injury or illness.


5D Mining is 100-percent employee-owned. That ownership means extraordinary performance by employees and outstanding value for clients. At the same time, local ownership ensures that local dollars remain in the community where our employees live and work.

Our reputation is built on our legacy of service; service to our clients, service to our employees, and service to our community. We are proud of our employees, whose generous giving includes their time, talent and expertise when volunteering, serving on committees, and lending a hand to those in need. Our employees donate hundreds of hours to a variety of community projects and organizations throughout the area. We encourage and support our employees in their desire to improve the quality of life throughout our shared community.
