（一）、施工测量准备工作
1．图纸审核：会同技术人员对图中大样尺寸进行校核，确保工程整体尺寸吻合无误，以便施工顺利进行，如有疑义直接同监理、设计洽商。
2．班组建立：设测量队长1人，主测2人，测工2人。
3．仪器、用具的配备及检定情况
4．以业主单位提供的现场点位及书面成果为定线依据。接桩后，立即对所接点位进行复核(包括书面资料数据计算复核、现场桩位实测坐标高程值与资料数值的复核)。将复核结果整理成书面材料上报监理，差值大于规范要求的，应再次复查，若情况属实，则在征得监理及业主同意的情况下，修正数值或将其作废。核对完毕，根据现场情况砌池护桩，并引出附桩，做好附桩图，以便日后桩点破坏的再恢复。
5．控制点加密：本段全线面积较大，故不宜采用单个的控制方法，为保证全线道统一，拟定采用城市二级附合导线做平面控制，每边平均边长设为200m，点位要求在路两侧交错埋设。内业计算使用计算机，采用工程附合导线近似平差程序，结果打印并保存。
6．高程控制点加密：在施工区线路两侧每隔100m均匀布设施工水准点，采用四等附合水准方法。
(二)、施工测量放线
1．平面定位：平面定位采用极坐标测设，应用计算机先计算出各桩位、桩点坐标以及放线数据，打印成书面表格形式。内业计算校核无误后，在现场将经纬仪置于加密控制点上，进行测放。放线完毕立即进行校核，用钢尺拉出和桩点的间距，同坐标反算之距离值比较，以此方法可校验同次放线各桩点之间的相对位置关系，不合格者立即复查并重放直至合格。平面相对关系校核完毕后，将全站仪置于另一加密控制点，实测桩点中相距最远的两点坐标，同设
