Setting survey process is applied to set out the exact position of a projected structure inside the legal boundaries of a plot of land. Get more details about Setting Out Services
The objective of setting out will be to set out great position and levels of building lines and road alignments to get a projected structure as per building plans by applying unique methods and instruments.
This sort of survey is very important when going to set up any type of construction work.
Generally, a set-out survey comprises of your process for transforming a building design onto the land itself in order that the builders can abide by the process all through construction. Throughout the process, main points are set up and markers are applied for the progression from the building process and sustain perfectness.
For huge scale projects like high rise buildings and developments, many set-out surveys are required as the building advances. This type of survey is primarily undertaken for the earthworks, roads, car parks, sewerage, water plus the actual buildings themselves.
Approaches of Setting Out Survey
1. Setting out buildings by coordinates
2. Setting out with theodolite and level
3. Examining verticality
4. Setting out and alignment in steel framed buildings
5. Alignment and verticality in type work
6. Control and computation for route surveying
Setting Out Building by Coordinates
A building is set out by adopting referencing from an currently established baseline. An asymmetrical building or possibly a building with complex geometry also can be established by applying the equivalent process. For every corner on the building, a grid line is setup in the baseline.
Examine Verticality - The verticality of points in a building is examined together with the following surveying instruments:
1. Plumb Bob (For buildings significantly less than 20m in height)
2. Optical Plummet (A transparent plastic sheet is used as a target for checking verticality of tall buildings)
3. Theodolite
Setting out Survey functions also includes the following :-
Calculations and setting out Approaches for:
1. Easy Circular Curves
2. Compound Curves
3. Reverse curves
4. Transition curves
5. Vertical curves
