Create original cinematic concept art of a massive industrial construction mecha working in a rain-damp coastal shipyard at dawn. Surround it with steel gantries, cargo cranes, welding sparks, unfinished ship sections, maintenance platforms and small safety-clad crews that establish believable scale. Design one graphite and safety-orange bipedal utility mecha with hydraulic arms, external winches, a protected operator cab and realistic service joints, carrying a large steel beam in a stable working pose. Use a 4:3 landscape frame from a low 28mm viewpoint with layered mist, wet reflections and cool dawn light broken by warm welding sparks. The machine is civilian construction equipment: no weapons, no military insignia, no visible pilot, no franchise resemblance, no logos, no readable text, no impossible joints, no extra limbs, no watermark.
