Purpose of the Assignment

The aim of this assignmentcapability to isunderstandto theassessprinciplesofsitethe stu surveying, cartographic detailing of construction works and the software available for site surveying.

Scenario

A private investment firm is planning to invest in a land, in order to build a theme park in a land in Nuwaraeliya. The land that is available was previously used as a tea estate, which is now abandoned. The land area is a hilly area with considerable slope variations. The firm has visited the site once, and is quite interested in investing in it. The location of the area as identified in the google maps is presented in the Figure 1.

Figure 1: Location of the site (Retrieved from earth.google.com)

The investment firm is currently in need of a proper surveying plan of the land and they have approached your surveying firm in order to award the contract for you to produce the surveying plan.


Task 1 (P 1-1, P 1-3, M1)

Suppose you are the team leader of the surveying team and you are supposed to do the following

tasks in order to fulfil the requirements.

(P1.1)

Describe the procedure that you are going to follow when producing the survey plan. You should describe the criteria for selection of stations when traversing, way of transferring control points, etc.

(P1.3, M1)

Describe the instruments that you are planning to use, including the electronic surveying

instruments.

M1 can be achieved if you have identified the errors and shortcomings of the instruments as well as the adopted procedure.

Task 2 (P 4-3, D1)

In order to commence the surveying field work, an initial traverse survey was conducted by your team and the following measurements were taken.

Figure 2: Traverse Stations

The whole circle bearing of line AB = 1820 127 2

Explain the process of correcting the coordinate points and obtain the corrected coordinates of the traverse stations. You may assume coordinates of point A as 1000 E and 2000 N.

To achieve D1 you should obtain the corrected coordinates of the traverse stations to the closest 1mm.

Task 3 (P 4-1, P 3-1, P 3-2, P 3-3)

(P4.1)

The survey team has obtained number of points in the existing survey land with the use of the total station. Describe the procedure that you are going to follow for the development of the contours from the point data available, by graphic interpolation.

(P3.1)

Explain the different applications of the computer software and evaluate the benefits of computer software to solve the following typical surveying problems, which might be helpful for the development of the plan with the observed points

B.1. Development of the existing plan of the site, with the points obtained from the total station

B.2. Generating the profiles of the proposed road sections

B.3. Identification of the cut and fill volumes with respect to the existing and the proposed ground finished levels


(P3.2)

One of the technical experts in your team is the site surveying work. Explain the use of information taken from the digital mapping

databases and how you can relate them to your site surveying project.

(P3.3)

One of the members argue that rather than using the total station it would be beneficial to use the GPS for this purpose. Evaluate the above statement by considering both positive and negative aspects related to use of GPS.

Task 4 (P 4-1, P 4-2, D3, M2)

A major section of the developed contour map is given in the following Figure (3).

Figure 3: Developed Contour Map


(P4.1, D3)

A part of the horizontal alignment of one of the roads is also indicated between the points A & B. Plot the ground sections of the existing road section (profile view) using the above

contour map.

D3 can be achieved by demonstrating innovation and creativity in plotting the profile view

using the contour map

(P4.2, M2)

From the contour plan produced above, the survey team wants to measure the area enclosed by a survey line. Following data is also available.

survey line (m)

Ordinate (offsets) (m)8.49.57.346.237.897.39.816.654.5

Explain different methods existing, to measure areas on prepared plans.

Calculate the area according to the field data given above using one of the suitable methods suggested above.

The team is interested in determination of volumes of earthwork involved in engineering works as well.

Explain the three major methods of measuring volumes for earthwork calculations

To achieve M2, the student needs to apply relevant theories and techniques in calculating the cross-

section area.

Task 5 (P 1-2, P 4-4)

The client wants to have an access road into the theme park from the East direction, but your team finds that in that direction there is a rock outcrop. So, if you want to have an access road you need to go around the rock, which involves a large horizontal curve.

(P1.2)

Describe the procedure that you are planning to adopt when producing the above large horizontal curve.


(P4.4)

Setting out is the(Bannister,Reverse1986).Explain theofaboveSurveyingstatementwith respect to the setting out and explain the procedures for determining setting out data for coordinated points.
