About C&M Construction Co

Founded in 2024 by husband‑and‑wife team Leonidas Carmona and María A. Mavare, C&M Construction Support Services was created with a clear purpose: to provide accurate, reliable, and highly organized technical support for civil sitework, underground utilities, and commercial paving projects. After years of combined experience in field operations, asphalt and concrete work, utility coordination, and construction administration, Leonidas and María recognized a growing need for specialized support that improves accuracy, efficiency, and project flow across the full civil scope.

What began as a small, independent venture has evolved into a trusted partner for civil contractors, paving crews, utility subcontractors, developers, and general contractors seeking dependable assistance in Estimating, Takeoff Quantities, Scheduling, Project Coordination, and Technical Documentation. Leonidas contributes deep technical knowledge in earthwork, utilities, paving operations, and field‑driven constructability, while María brings strong organizational skills, documentation expertise, and a detail‑oriented approach to managing project workflows. Together, they form a balanced team dedicated to strengthening the operational and technical foundation of civil construction projects.

At C&M, we believe that successful civil work depends on more than equipment and materials—it requires accurate quantities, clear timelines, coordinated sequencing, and well‑structured documentation. Our mission is to reinforce those elements so our clients can focus on delivering quality work in the field with confidence and control.

We take pride in offering personalized, high‑quality support that improves communication, reduces delays, and enhances overall project performance. As a family‑founded company, we value integrity, transparency, and long‑term relationships built on trust, consistency, and result
