LINEAR MEASUREMENT IN SURVEYING

Image
In construction projects, there is erection of different structural and non structural members (components) to their adequate position to form a required structure. The positioning of structure components into their accurate and precise position is done by through surveying by considering both vertical and horizontal references. In either vertical or horizontal referencing there is either linear measurement or angular measurement sometimes both. Linear measurement in surveying refers to horizontal or vertical measurement of linear distances on earth’s surface so as to allocate different features either man made or natural.   Units conversions in linear measurements   In linear measurements, there are two most preferable, acceptable and used systems of measurement which are metric and imperial system of measurements. The two systems units can be converted as follows. Conversion of distance measuring units Instruments used for linear measurement Various instruments are...

SETTING OUT OF SIMPLE BUILDINGS

Image
Setting out in general Setting out is the process of establishing points and lines on the ground as the reference to define the position and level of different physical features such as pipes, bridges, culverts buildings for construction works accordingly to drawings. Setting out of buildings This is process establishing points and lines on the ground as building elements markings with respect to drawings provided. The building elements can be foundations, pads, columns and walls. This involves transferring of drawings dimensions on paper to the ground so that actual building can be seen on the ground as shown on drawings. This activity involves transferring of drawing dimensions as shown in papers to the ground, so that actual building is seen on the ground. STEPS TO CARRY SETTING OUT OF SIMPLE BUILDING (By 3-4-5 method). After receiving the required drawings that are architectural and structural drawings to be used for setting out, these drawing are used as reference to define positi...
