On the construction site, there are several distinct colors. As the different colors of reflective vests flow among the construction site, it seems like a dynamic safety map, safeguarding the daily safety of thousands of workers and also outlining the meticulous contours of modern engineering management. 

I. The Safety Logic in Colors: From "Chaos" to "Clarity"

In traditional construction sites, a thousand people wearing the same vest. The steel reinforcement installation workers skillfully put on orange-red reflective vests. This color is the exclusive identifier of the "steel reinforcement team" on the construction site. Behind the uniform yellow reflective vests, a recognition problem lay: in an emergency, who was the electrician? Who understands mechanical operation? Not far away, the electrician in a yellow vest is carrying cables towards the equipment area, the supervisory officer in a blue vest is holding a record sheet to inspect the work area, and the project manager in a white vest is standing in front of the sand table. Now, each color represents a different type of job.

II. Mobile Management Nodes: From "Human Sea" to "Grid"

In the steel processing area in the afternoon, the supervisory staff wearing blue uniforms are scanning the QR code on a worker's vest with their mobile phones. Instantly, the screen displays the worker's name, job type, training records, and health status-this "digital ID" hidden inside the reflective strip provides data support for color management. "Not only do we need to know 'what color he is wearing', but also 'what he can do'." The supervisor explained that different colors of QR codes are associated with different permission systems. For example, the QR code of the yellow electrician vest can open high voltage...

III. Professional Dignity Hidden in the Jacket: From "Ambiguity" to "Clarity"

In the evening cafeteria of the construction site, workers in different colored jackets sat together. In the past, due to the phrase "all are workers", the division of professional roles was often blurred. Now, the color has become a natural topic of conversation: "The orange-colored jackets today have tied the reinforced concrete cages very neatly." "Thanks to the yellow jackets, the electrical circuit hazards were promptly detected and resolved". This recognition based on professional identity has quietly changed the interpersonal relationships on the construction site.

As the last ray of sunlight passed over the construction site's tower crane, the fluorescent stripes on the various reflective jackets became even brighter in the dusk. They not only reflected light but also reflected the wisdom of modern engineering management, using the most intuitive color language to solve complex safety problems; with the simplest identification design, activating the inherent driving force of collaboration. Behind these flowing colors, there are the safe return journeys of countless construction workers, and the solid steps of each super project moving from drawings to reality.
