About
My name is Costa Andrianakis
I founded Helios Infrastructure after more than a decade in Tier 1 delivery to provide subcontractors with flexible access to senior engineering and project management.
Through that experience, three things became clear:
-
Infrastructure work is not won on price alone.
-
Risk is often introduced through missing or poorly framed bid details.
-
How a submission presents a business can be as important as what it prices.
Helios exists to support both contractors entering the infrastructure market, as well as those already established to win better work and deliver projects with stronger commercial outcomes.
