Our Story


In 2020, two powerhouse Colorado construction companies PLM Asphalt & Concrete LLC and Rocky Mountain Excavating (RME) joined forces to become Elite Surface Infrastructure (ESI). For over 20 years, clients across private, commercial and federal sectors have leaned on PLM and RME’s passion and expertise to create a finished product that’s built to last.

Customers today can expect the same quality of service, only now it is backed by a partnership that has created the largest company in Colorado that self-performs Civil Construction and Asphalt & Concrete Maintenance for Commercial, Municipal and Governments projects.


The RME and PLM relationship was solidified over decades of collaboration. Clients have always depended on our companies to value-engineer a solution. Your goals and interests are always top of mind.

Customers can now leverage a century of combined experience that our management and estimating team bring to the table. We embrace a “we have your back” mentality by supporting clients with comprehensive capabilities to get the job done right.

If you have surface infrastructure needs, our uniquely nimble and flexible capabilities deliver. With a team of over 300 skilled field employees, a company-owned fleet of advanced heavy equipment and long-standing relationships with local rental companies and contractors, we are specifically designed to efficiently help you execute and administer complex projects. Your environment is guaranteed to look good and be safe for the long haul.
