Welcome to AHK Infra / SHEET 01

A steel detailing team that works while you sleep.

We're a structural steel detailing organization built around one idea: give clients a team of talented engineers that feels like an extension of their own office. We're able to run day and night shifts when a project needs it, so your timeline never waits on a time zone.

Our engineers work across structural detailing, 3D steel modelling, and reinforced concrete design — turning architectural intent into fabrication-ready drawings clients can build from with confidence.

We hand you the model and the math — you cut the steel.

Every beam, column, and connection is modelled in TEKLA and calculated before it ever leaves our desk, so your fabrication shop can cut straight from our drawings and your crew can erect straight from our plans — no guesswork, no back-and-forth.
