日本大成公司对施工测量特别重视。从挖土开始到主体工程结束,对施工中平面及高程控制都是由测量人员完成的,精度要求十分严格。轴线和标高误差均控制在±3毫米以内,为保证工程质量提供了先决条件。在日本大成公司,对高层建筑中现浇钢筋混凝土楼面标高测设,一般先将现浇框架楼面钢筋绑扎好,即由测量人员进行标高测设,严格控制标高误
Daesung Corporation has paid special attention to construction surveys. From the beginning of excavation to the end of the main project, the control of the plane and elevation during construction is completed by surveyors, and the accuracy is very strict. Axis and elevation errors are controlled within ±3 mm, providing prerequisites for engineering quality. In Japan’s Dacheng Corporation, the elevation of cast-in-place reinforced concrete floors in high-rise buildings is measured. Generally, the steel of cast-in-place frame floor is tied up first, that is, the surveyor conducts elevation measurement and strictly controls the elevation error.
