AIM

Collecting of Digitally survey data by total station for designing by advance software for achieving higher accuracy in short time.

1. Total Station includes Theodolite, Electronicdistance measurement (EDM) & data recorders.

2. We collect vertical & horizontal data in a singleoperation. Data recorder can record information inthe field to take back to the office forprocessing.

3. Data recorders can also be used to downloadpreviously determined data at the office for use inthe field to stake out or to locate constructioncontrol points & boundaries.

4. We can also designed traditionally(manually),data collected by the Total station in data recorders.

INTRODUCTION

Role of Total Station in Preparation of Highway DPR

In Highway Detail Project Report (DPR)preparation. Total Station is used forcollection of all Survey data digitally.

Digitally collected survey Data furthertransferred to a computer to create Digitaldesign model by any designing software.

Designed Data up loaded in Total Stationfor further staking out on ground.

How Total Station works

Total Station collects all ground data in Three Dimensional

Format (Co-ordinate system).

Prior to collection of data, it requires at least two known points

(co-ordinates known), to set up the station.

After setting up the station it gives / collects the details of

points w.r.t. the two known points from the Station.

Total Station measures horizontal angles in WCB system

automatically from the assumed Meridian as worked in Station

set up and the Vertical angles from the Horizontal axis of the

instrument [above (+), below (-)].

. As this instrument gives all the engineering details of a station

/ point , the instruments has been named as Total Station.

Setting up the TripodOpen the tripod legs enough to for the instrument

to stable.

Locate the tripod directly over the station point. To the check tripod position look through the center hole in the tripod head.

Firmly press the tripod ferrules into the ground.

Level the top surface of the tripod head.

Securely faster the thumb screws on the tripod legs.

Place the Base plate on the tripod head

Tighten the tripod mounting screw.

LEVELING

Firstly level the base plate level by tripod legs slide

Place the instrument on the base plate and fixed by leveling base plate clamp

Loose the upper horizontal movement plate clamp

Level by THREE LEGS METHOD

Conclusion Every engineering project, surveying isthe first step of the execution of the success ofany engineering project. And it is based uponthe accurate and complete survey work prior tocommencement of project as well as duringexecution and after completion.

Hence the survey by TOTAL STATION ismost important for accurate estimate in lesstime and execution of work.
