1.0 INTRODUCTION

Construction surveying or setting out is to stake out reference points and markers that will

guide the construction of new structures such as roads or buildings. Setting out is generally

performing existing conditions of the future work site, including topography, existing

buildings and infrastructure, and even including underground infrastructure whenever

possible. After finishing our three previous surveying works (leveling, traverse and

tacheometric ), we then continue our surveying work with setting out. Setting out can be

defined as the process of using the surveying instruments and techniques described in

preceding chapters to transfer information from a plan to the ground. There are three distinct

elements to the task horizontal control to ensure that the new works are in the correct place,

vertical control to ensure that they are at the correct level and vertical alignment to ensure

that multi-storey or underground construction is plumb. Information on the drawing

concerning the proposed works must be transferred to the ground in a format that can be

understood by all levels of the workforce on site.

2.0 OBJECTIVE

To expose student to setting out works and prepare before build a building.

To make a laying out at the corners of a proposed building according to the dimension

taken from building site plan.

3.0 EARLY PREPARATION

To check and understand the suggestion structure designs for see the obstacle around

the setting out work point in the design.

To do surveying and check at the construction site. Determine the suggestion referring

points.

In this setting out work, the traverse point can be the referring points.

5.0 PROCEDURE

1. The traverse and tacheometry plan were used which is from previous project.

2. A suitable area was selected for suggestion of a building construction in the traverse

area.

3. A line of traverse and a station were taken as observation station.

4. Station 2 was chosen as control point and line station 2 to station 3 as a reference line.

5. Bearing and distance of every point of the building area were determined by using

AutoCAD.

6. Setting out work was started.

7. The total station were set at station 2 and observed at station 3. Bearing station 2 to 3

were set as reference bearing.

8. Then bearing station 2 to point A was set to determine the point A location.

9. The pole and mini prism were moved to get exact distance.

10. Measurement the distance were done on point A,B,C,D,E and F. Every point was

marked with a picket.

11. After finish, recheck can be done by measure the distance using measuring tape.

12. The shape of the building was produced.

13. The plotting building points were done in Techeometry plan by using AutoCAD and

setting out plan was produced and report was done.

Setting out work is done to get the design point for a building after the tacheometry

survey work. An area is selected in the traverse areas as a site project to build the building in

this survey work, a systematic management is important to make the work flow is easy to do.

The field work must finish first to get the bearing and distance that will be use in

setting out survey work. To determine the bearing and the distance, calculation should be

done on the plan for each point of the building that we want to build. The purpose field work

is just to mark the point which has been plot in the purpose building plan.

Based on our traverse area, we plan a building that is an L shaped bungalow inside the

boundary of the traverse. First each corner point of the building that we want to build is set

out using pickets.

The setting out work is done, recheck to make sure every peg is in a right location.

Diagonal method is use in this process. Total station must be in a good condition and also the

peg location must be in the right place to determine the point location precisely to avoid the

error.

8.0 CONCLUSION

The setting out work was done, we had made a conclusion about determine the point

at the building that we want to build. From our tacheometry work, we are able to determine

the site, to locate the new building that is going to be constructing. From the purpose

building plan, we designed the building location and transfer it to the ground surface. If the

setting out was not accurate, the building that we want to build would not be at the correct

location and size. This will contribute a lot of problems while and after the construction

work. Hence, the accuracy of the setting out is very important to guarantee the comfort and

safety to the people. From all these data that we have, we have set the exact location for the

building by using pegs.
