This paper discusses the design principles of prefabricated beam yards in bridge engineering, emphasizing key considerations: engineering schedule, investment costs, intra-yard transportation, safety, and space utilization. Scientific layout and comprehensive planning are vital to ensure efficient, economical, and safe beam production, laying a foundation for bridge project implementation.

In road and bridge projects, cast-in-place construction is currently the primary technology for box girder structures, which are composed of steel box girders and reinforced concrete box girders with stable structures. This article focuses on the quality control measures for cast-in-place box girder construction in road and bridge projects.

This article briefly outlines the principles of cantilever formwork construction in municipal road and bridge projects and discusses the technical key points and quality control of cantilever formwork construction in such projects.
