Raminha Construction, Inc. is an earthwork and underground utilities contractor proudly serving San Luis Obispo and Santa Barbara Counties since 1985. Founded by Cayucos native David Raminha, RCI is built on decades of hands-on experience, a deep commitment to quality, and a strong connection to the community we call home.

 

For nearly four decades, we have delivered projects ranging from residential site development to complex public works and emergency response. Our clients include long-standing partners such as the County of San Luis Obispo, County of Santa Barbara, City of Paso Robles, City of Atascadero, Waste Connections, and Lucia Mar School District, many of whom return to us again and again because they trust our reliability, craftsmanship, and collaborative approach.

 

As a smaller, close-knit company, RCI is known for its personal service. Clients value that with us, everyone knows everyone, and every project gets the attention it deserves. Whether serving as a general contractor or subcontractor, we approach each project with integrity, accountability, and efficiency, delivering results on schedule and within budget.

 

Our philosophy is simple: strong relationships create strong outcomes. By fostering open communication, trust, and teamwork, RCI not only builds successful projects but also strengthens the communities we serve.
