Dr.Depak Muniraj Civil Engineers Training Institute®: Marking with total station

• Marking is the process of establishing temporary frames of references, so as to use them to complete a given activity according to its dimensional and positional requirements

• Marking helps in maintaining

– Dimensional accuracy

– Nullifying or minimizing errors

Price of total station is starting from one lakh rupess varies upto 10lakhs based on features and accuracy.

We recommend SOKKIA for optimal usage.,

First step we need to take permanent benchmarks and transfer it to the site.

Then TBM(Temporary Bench Mark) need to be established in the site.

There co-ordinates (longitude and lattitude) with GPS device need to be marked down. From there as a reference, we need minimum two back sight which co-ordinates are known.

So instrument can be setup and new points can be marked now.(i.e foresight)
