在设备安装前，应首先根据基础图检查地基的施工情况。应以零平面为基准，检

Before installation, according to the construction should first check the case of FIG base foundation. Should be zero as a reference plane, each mounting position detecting whether the drawings and recorded. Meanwhile The base construction should draw lines in FIG ink surface location cord device, for reference during installation.

About The Topography survey: The process of how the survey will be summarized in the file "requires a BETA survey" and the results of the survey work will be reported in the "BETA Topography Survey Reports" file (the file includes only the headings to perform , the content will be updated when the survey ends)<br>About geotechnical survey and Geological Survey (Geological Survey): The volume of Geological Survey (geotechnical survey) will be hosted by the project request and geological Engineers (geologists) will conduct survey, analysis and geological assessment of the project as requested by the owner M the project, steps for implementing this survey will be summarized in the "Request for a BETA survey" file. In Vietnam, the results of geotechnical survey and Geological Survey will be reported in 1 single file "Report of BETA Geological Survey work" (the file includes only the headings will execute, the content will be updated when the survey work ends)<br>About hydrological survey, PEC will carry out Hydrometeorologic survey (hydrological survey), this work has included the Hydrological Task (hydrograph survey): The Hydrometeorological survey will not perform groundwater assessment of the project (for This work will be done and reported in the Geotechnical Survey and Geological Survey section), the Hydrometeorologic survey will include tasks such as collecting documents, the necessary data on hydrogeological and regional climate to cater for design work , ). The steps for implementing this survey will be summarized in the "Request for a BETA survey" file and the results of the survey will be reported in the "BETA hydrometeorological Survey Report" file (the file includes only headings that will perform , the content will be updated when the survey is finished). ...

Before equipment installation, the foundation construction shall be checked according to the foundation drawing. The zero plane shall be taken as the benchmark to check whether each installation position meets the requirements of drawings and make records. At the same time, the construction personnel shall draw the location line of the equipment on the ground with ink line according to the foundation drawing for reference when installing the equipment.<br>
