CE 6404 Surveying II Notes
Surveying II Notes for Civil 4th Sem Notes. This subject deals with geodetic measurements and Control Survey methodology and its adjustments. The student is also exposed to the Modern Surveying.
Surveying II Study Materials
Survey grid is one which is drawn on a survey plan, from the original traverse. Original traverse stations form the control points of the grid. The site grid used by the designer is the one with the help of which actual setting out is done. As far as possible the site grid should be actually the survey grid. All the design points are related in terms of site grid coordinates.
Surveying II Notes,The structural grid is used when the structural components of the building are large in numbers and are so positioned that these components cannot be set out from the site grid with sufficient accuracy.
The structural grid is set out from the site grid points. The secondary grid is established
UNIT- I CONTROL SURVEYING
Horizontal and vertical control – Methods – specifications – triangulation- baseline – instruments and accessories – corrections – satellite stations – reduction to centre- trigonometrical levelling – single and reciprocal observations – traversing – Gale‟s table.
UNIT – II SURVEY ADJUSTMENT

Civil Engineering Notes
Civil Engineering Notes, Civil Engineer have to deal mostly soil, rocks, roads, bridges, canals, dams, buildings and concrete. All the civil engineering projects have planning, design and construction section.
In all this section basic knowledge about the site and about the material is more important. We are developing our nations of infrastructures.
We provide all the notes for the students benefit for upcoming semester exams. For other subject notes contact to Click below the link to download the notes.
