Work procedure for excavation at construction site involves understanding of centre line and excavation drawings, setting out of plan on ground, excavation of soil and removal of excess soil.Quality checks such as recording ground level and marking of reference points should be done.Excavation is the process of moving earth, rock or other materials hellip.

Relative level in surveying refers to equating elevations of survey points with reference to a common assumed datum.It is a vertical distance between survey point and adopted datum plane.Thus it is considered as the base elevation which is used as reference to reckon heights or depths of other important places.Reduced here means equating and level means elevations.
Final level proposeddesigned level estimate or formation level survey data let us consider the following example where the survey data is converted into grid levels as shown below and the final level is 20 meters.3rd main road, mahalakshmi layout, bengaluru 560086.

Definition of road or pavement.Pavement or road is an open, generally public way for the passage of vehicles, people, and animals.Pavement is finished with a hard smooth surface.It helped make them durable and able to withstand traffic and the environment.They have a life span of between 20 30 years.Road pavements deteriorate over time.
This deals with the gradients, slopes and levelling of the ground.Perspective view or front view or side view of the road alignment makes you understand about vertical alignment.Importance of highway alignment deciding the highway alignment is the most crucial part of road construction.Road construction involves a lot of land acquisition.

A hill road may be defined as the one which passes through a terrain with a cross slope of 25 or more.There may be sections along hill roads with the cross slope less than 25, especially when the road follows a river route.Even then these sections are also referred to as hill roads.
Trigonometric levelling indirect levelling trigonometric or indirect levelling is the process of levelling in which the elevations of points are computed from the vertical angles and horizontal distances measured in the field, just as the length of any side in any triangle.
Levelling applications 1.Longitudinal sections of.Longitudinal sections of ground level in road and sewer construction.Use of levelling for road and sewer design.Formation of contours levelling can be used to form contours, with the methods of gridding and radiating lines as shown below in figure 5.
Road pavements may meet the necessary requirements directly, or after breaking and mixing with other materials.Clearing, grubbing and excavation procedure manual may 2001 page 4 of 52 1.3 drainage and channel excavation during construction, ditches are required to be maintained to ensure proper drainage at all times.
Road reserve and placed in embankments at a distance of 50m or less from its original position, measured along the centreline of the road.1119 culvert a structure other than a bridge, which provides an opening under the carriageway or median for drainage or other purposes.1120 cut a section of the road where the formation level is below.
Levelling definition, having no part higher than another having a flat or even surface.
The table below shows ground levels and formation levels for a proposed road construction.Embankments are to be built with side slopes of 12.5 and cuttings with slopes of 13.The embankment crest width and cutting base width is 13m.It may be assumed.
