Question

of 1eveling process that determines the elevations of a series ints at uniform intervals (tations) along a continuous line or a storm sewer or the center line of a roadway, is referred to as is a surveying method used to determine the 3astference in evation between Ewo or more points using a opirit level and a graduated rod is a theoretical reference plane to which all 34 re referenced, example Nean Sea Level re and permanent point of known elevation is called vertical distance or height of a point above or below a given 35- A secu datum surface is called 37- When running a level circuit, a tempo rary benchmark used to re-establish the height of the instrument after it has been called a moved is 38- When running levels, a rod reading taken on a point of known elevation 39- When running levels, a rod reading taken on a point of unknown elevation 40- The following formula .BS-.PS BM.beg BM.end is used to determine is called a back sight or a is called a foresight or a the presence of mathematical errors in level notes before leaving the field and is referred to aS 41- When leveling, a technique used to eliminate the error that occurs when the rod is not held vertically 42- When performing layout work with an EDM, the instrument can be switched to the allowing the priem pole to be moved back or forward along the line of sight until the correct distance is located and marked 43- The equation for computing the volume of earthwork (cut or £111) between adjacent cross-sections of a highway or railway route. 44- When computing earthwork volumes for contract quantities at a construction sight do you multiply or divide by 9 or 27 when converting cubic feet to cubic yards 45- The type of survey performed to physically establish the positions of property lines and corners is called 46-A and plan provides information on the shape of the land including relief, contours, elevations and the relative positions of existing natural and man-made features drawn to scale. 47- A type of construction survey to establish both horizontal and vertica control, to obtain topographic data, and to lay out the positions of highways, railroads, streets, pipelines, or any other linear called a project is 48- A type of survey that sets a high level of accuracy and precision both horizontally and vertically, and less accurate surveys can be based is called provides a framework upon which

Answer 1

ANS 32-Profile levelling is the levelling in which the elevation of a series of point sof uniform intervals along a continious lines.

Ans-33-Spirit levelling or the direct levelling is the surveying ,ethod used to determine the difference in elevation between two or more point using a spirit level and a graduated rod.

Ans-34-Datum is the theoritical reference plane to which all elevation are referenced.

Ans-35-Bench mark is a secure and permanent point of known elevation.
