 the drawings, first to become familiar with the drawings, mainly about the following aspects: 1) pages of drawings and diagrams, maps; 2) a comprehensive understanding of drawing; 3) finding of design-driven dimensions (), do not resize and adjust the size; 4) questioned the drawings; 5) develop buries a construction programme and technical clarification; 6) clear corners and special treatment; 7) controlled construction drawings to verify construction scheme and design. (2) at the construction site to find subject planted area: various engineering, first on the scene to find planted area, it must first understand the curtain wall installation section, and some projects are all curtain wall, the entire project is a region-wide, only partial walls, the zone is local. (3) identify the axis positioning: positioning the drawings shown in axis compared with the actual construction site to find out exactly where the axis positioning, axis positioning function are: 1) to help determine the origin of curtain walls; 2) acceptance of the installation is accurate; 3) adjust errors, and determine the error range. (4) find anchor points: according to site to find the exact location of the axis, according to the drawings provided by the content determine the positioning point; number of anchor points shall not be less than two points. Repeated measurements determine the location points must ensure that the positioning is correct. (5) take level (level): level (minor works available in horizontal pipe), the two anchor points determine the horizontal position. Level according to use the drawings, first to become familiar with the drawings, mainly about the following aspects: 1) pages of drawings and diagrams, maps; 2) a comprehensive understanding of drawing; 3) finding of design-driven dimensions (), do not resize and adjust the size; 4) questioned the drawings; 5) develop buries a construction programme and technical clarification; 6) clear corners and special treat
