Pentágono

About Pentágono

Pentágono offers multi-disciplinary design services for LNG, midstream, data center, and energy and transmission projects across the Gulf Coast. We combine responsive project management and scheduling services with deep technical expertise to deliver piping, structural, and infrastructure design at the pace your project demands.

To be the engineering partner that construction teams trust to keep their projects moving — with speed, precision, and zero bureaucracy.

Our Values

The principles that shape how we design, collaborate, and deliver.

Speed Without Shortcuts

We deliver fast because our engineers are experienced, our processes are lean, and our team is empowered to make decisions — not because we skip steps.

Field-First Thinking

Every drawing we produce is designed to be built, not just to look good in a review. Our engineers spend time in the field because that's where engineering meets reality.

One Team, One Answer

Multi-discipline integration means you get one coordinated answer, not three conflicting ones. Our piping, structural, and mechanical engineers sit together, work together, and deliver together.

Safety is Engineering

Safe design isn't an add-on — it's the foundation. Every calculation, every detail, every field solution starts with the question: can this be built and operated safely?
