Summer Training

University of DammamCollege of EngineeringDept. of Construction EngineeringSummer Training 2013-2014/1434-1435

*Introduction A simple introduction will be demonstrated to clarify the basic

surveying concepts.

*Surveying Science :activities involved in the planning and execution of surveys fro

the location, design, construction, maintenance and operation of civil and other engineered projects

*Surveying Objectives :

• To collect field data

•   To prepare plan or map of the area surveyed;

•   To set out field parameters at the site for further engineering works.

• Supply essential data for all construction stages

*In this summer training , we perform various tasks in the field which was a practical application of engineering surveying

*After each task performed we submit a technical report showing all the steps and details of the task

*The projects executed during the training :

Project 1: Engineering Surveying for the project Development

Project 2: Producing Topographic Map

Project 3: Producing Contour Map

Project 4: Setting out Highway route or Drainage

Project 5: Setting out a project

*Project 1&2:Engineering Surveying for the project Development &Producing Topographic Map.

*Objectives:

Identify the different ways to produce topographic maps that help in the engineering design.

Identify the devices used and the methods used in practice

Learn how to draw topographic maps

*Procedures:

At least 5 control points (CP) with minimum length of 30 m have to be established at proposed site. Then pegs are driven into the ground at the CP for Permanent markings of the Area .

Conducting the traversing, levelling and tacheometry to get data for producing the map

After all the data have been analyzed, draw the topographic map of the site proposed.

*Producing topographic map :

Topographic Map using AutoCAD

*Project 3 : Producing Contour Map:

*Objectives:

Indentify the equipment and the methods used in practice.

Knowledge of the preparation of contour map.

How to use contour maps in the design projects.

*Sketch of the Site:

*Procedures:

Divide the outer frame every 10m and install peg to each point

Setting out cross-sections at each sector 10m.Work outside the framework of the leveling Along the line connecting BM to BS, set a chaining

pin every 10 m and name them ( A,B,C….).Work of leveling for the inner sectors

*Sketch of the Grid Using AutoCAD:

*Using surfer program to plot the contour map:

1. Contour map:

2. This map shows the contour as three dimension :

3.This map show how the water flow in the site:

*Project 4:Setting out Highway route or Drainage.

*Objectives:

Identify the equipment used in the field of setting-out road or drainage and methods used in practice.

Knowledge of drawing longitudinal and cross section lay out plan.

Knowledge of calculating earthwork quantities.To obtain setting out points for a simple circular

curve by pre-computation and hence execute the fieldwork based on the data computed.

*Sketch of the Site:

*Sketch of the Curve:

*Procedures:

Mark the tangent points (T & U) on the ground from the intersection point (IP), based on tangent length and the total deflection angle (θ).

setting up theodolite or to total station at T and conduct the temporary adjustment.

set reading 0°00’ on theodolite, and shoot the telescope at IP as reference station.

After that, we rotated theodolite based on the first deflection angle and chord length from pre-computation data and mark the point on the ground.

repeat the same procedure for the second deflection angle and chord length until reach the tangent point U.

*Sketch Of Longitudinal and Cross Section :

*Project 5:

Setting out a project.

*Objectives :

Obtain setting out points for a building based on the control points observed by pre-computation and hence stake the building points.

*Procedures:

Doing some calculation for dimensions that are not clear.

Setting out the profile borders (out of building by 2

meters)

Establish a base line to which all the setting out can be

related (to identify the exact dimension of your building )

Establish the grid line Using total station to make sure the

angles between lines are 90 and marking the grid line

intersections with pins.

Using a tape in some places where you can control the

distance.

We make sure again that all the points of the buildings are in them place.

Note:this task is usually undertaken once the site has been cleared of any obstructions and any reduced level excavation work is finished.

*Conclusion :* This training was great experience at which

a lot of benefits was satisfied such as :

Supporting the practical side of the student

Giving the student the opportunity to make decisions

Promoting the problems solving skill

Being familiar with the latest technology (GPS , Total station ,levels , ....etc)

Preparing the student for future field work

Enhancing the skills of communication ,group work, time management

After listing these benefits we can conclude how this training experience help us as “Future Engineers”
