CEO MESSAGE

Message from our CEOs

HANUL D&B opened its doors in 2024, founded by engineers who had spent years working across both design and site for ground and tunnel projects.

We begin by asking how a drawing will actually be built and how the ground will respond. That is why we treat tunnel design, underground safety assessment, earth retaining works and ground investigation as one continuous process rather than separate tasks.

Through our corporate R&D centre we develop our own tools — automated numerical analysis and AI-based analysis modules — turning accumulated experience into faster, more reliable judgement.

We intend to remain a small but solid engineering organisation. Thank you.

Meet the two co-CEOs leading HANUL D&B.
