The main boarding area at high-speed rail and subway stations is the platform. Paving operations on the platform surface have a significant impact on people's travel. Excessive platform surface paving can prevent vehicles from opening and closing normally, hindering station operations.
[0003] During the current platform renovation project, construction workers have little understanding of the required clearances during the paving process. Most points require re-surveying using CPIII points provided by the station's front-end and design teams. During renovation work, technicians and construction workers are unable to meet the requirements for construction surveying, and some projects require the secondment of surveyors to ensure on-site paving operations.
[0004] However, due to the excessively long turnaround time for the CPIII points handed over by the pre-station and design units, the platform paving schedule could not be met, significantly impacting project performance. Furthermore, if later boundary surveying units, such as the building construction section, encountered problems during static acceptance testing, they would report them to the company, negatively impacting the company.
