Summary: In this role, you will be responsible for executing high-precision geodetic and topographic surveys, establishing accurate local coordinate systems, and ensuring precise structural alignments for metro and bridge segment casting beds. Your work will serve as the foundational link between field data collection and engineering design, ensuring that all precast elements are fabricated and installed with exceptional dimensional accuracy. Responsibilities: Conduct comprehensive topographic, boundary, and hydrographic surveys using advanced surveying instruments and technologies. Establish and verify structural alignments for metro lines, highways, viaducts, and bridges, ensuring compliance with design specifications. Set up and maintain precise local coordinate systems for precast casting beds and construction staging areas. Process raw field survey data into accurate layout drawings and digital deliverables for engineering and construction teams. Collaborate closely with design en...
