Subsurface Construction = Risk.

Construction activities below ground usually present the most significant risk to a project in terms of cost and schedule. Quanta Subsurface brings together a team of specialized foundation engineers and constructors focused on reducing this risk and maximizing value.

Value Proposition

Value Proposition

We believe our customers receive the best value when they partner with a design-construction team. We promote an integrated engineering, procurement and construction (EPC) or Construction Manager / General Contractor (CM/GC) approach over traditional design/bid/build. Our core competencies focus on innovation, value engineering, construction efficiency and partnership with project stakeholders.

Team Members

Our services are efficiently delivered through Quanta foundation entities entrenched in their industry or geographical region. Quanta’s culture of entrepreneurship has allowed many of these firms to continue to operate under original management, resulting in an irreplaceable passion for employees, customers and projects.
