1. Generic Assignment Information

1.1. Introduction

This assignment takes the skills and knowledge you have gained from Modules 4 onwards and combines them into a survey project scenario for you to work through. Keep in mind that this is an assessment of what we are learning in this course, so some liberties have been taken when designing the scenario to ensure it remains at a level suitable for this course.

It is not intended to be a comprehensive exercise in survey projects, nor is it intended to 100% accurately reflect normal work procedures – we’re only first year surveying!

1.5. Assignment presentation guidelines

This assignment is predominantly a surveying mathematics exercise. As this is a first-year course, your submission may be neat hand-written solutions, typed solutions, or a combination of the two.

Ensure your name and student number appear at least once in the body of your assignment (preferably on the first page).

Label each Task or sub-task clearly, so your solutions are easy to follow.

For repetitive calculations (i.e. columns of values that use the same formula), you may use a spreadsheet program to generate the values required, however, you should provide a sample calculation for each column/row as required.

1.6. Submission Instructions

All submissions should be digital and made through the StudyDesk Assignment submission link.

Before submitting your assignment, check the file you are submitting – are all the pages legible? Have any images/scans been accidentally cropped? Are the pages in the correct order? Have you got copies of the same page, or pages missing?

If you do not have a scanner at home, Adobe makes a free mobile scanner app that uses your mobile/tablet camera to take scans of documents and converts them to PDF. It is very easy to use and produces clear results. There are probably other scanner apps out there, but at this one has the benefit of being from a trusted source.

A submission checklist is included as Appendix A.

Use the following naming convention for your files:

o SVY1104_A2_[SurnameInitial]_[StudentNumber].xxx

o Where [SurnameInitial] is replaced by your surname and your first initial (eg Jessica

Smith would be SmithJ); and o [StudentNumber] is replaced by your 10 digit student number (eg 0061234567)

2. Assignment Body

2.1. Introduction

Your company has just landed a large project to be the project surveyors and designers for the development of a parcel of land. You will be one of the lead surveyors for the project, so you are going to be heavily involved in both the design and the construction phases.

The planner has provided your company with the first draft of the site design, but it is your job to calculate the design to ensure it fits within the boundaries of the lot and that there are no miscloses in the proposed roads.

You will also be entrusted with managing the survey control for the site, which means you will need to design and place any marks required for the life of the project. Of course, you will also be involved in the field work for the project as well, so you need to ensure your equipment is fit for purpose.

2.2. Assignment Questions

The project site is Lot 71 on SP 291400, close to the train station in Springfield Central, Queensland.

Please see 2.5 Appendix B for a map of the site, including existing survey marks in the area.

2.2.1. Task 1 – Site design [120 marks]

The client has provided you with a draft design (see Figure 1) which you will need to calculate and check for errors. In the southern half of Lot 71 a new boundary is to be created, as shown in blue dimensions. Check the close of the southern lot enclosed by the existing boundaries and the proposed new boundaries.

1. Use Bowditch Adjustment by Vector to distribute any misclose in the proposed boundaries.

(30 marks)

2. If this new boundary were a traverse, would it have been appropriate to adjust the lines, assuming the traverse was of a normal standard? What would you recommend doing to improve the traverse if it were not suitable?

(10 marks)

Figure 1 Proposed boundaries for southern lot and dimensions for new cul-de-sac.

There will also be a new cul-de-sac built for the development. It will come off perpendicular to the existing stub road (180°00, 6.53) into the lot and be designed to fit the dimensions shown in Figure 1.

Assign 0m chainage to point A and increase through to point H, along the straight and curved lines. This chainage is applied to the perimeter of the cul-de-sac (not the centreline, as it would normally be). The intersection angle of curve CP3 will be close to 90°.

3. Calculate the perimeter of the cul-de-sac.

(40 marks)

4. Assuming you are set up at the common tangent point between the two 10m radius curves, calculate the setout bearings and distances for the even 10m chainages around the perimeter of the cul-de-sac, as well as all the tangent points for each of the three curves.

(40 marks)

2.2.2. Task 2 – Control design [40 marks]

1. Now that you have the design for the site finalised, you are able to look over the site and come up with a proposed site control design.

(10 marks)

Of course, a desktop design cannot be finalised until a site visit, but this is a starting point to work from.

Some points to consider when deciding on the locations for the control marks:

• Likely line of sight between marks

• Limit the distance between marks to 150m or less (use the measurement tool in Qld Globe to approximate)

• Forward plan the project and try to place internal marks away from areas where they are likely to be knocked out early during construction (so not in the roads, for example)

• Ensure you have good geometry – don’t load all the marks to one side or one corner

• Make sure there is control around the outside of the site as this is likely to survive, allowing you to place new control as required

• Which existing marks you are connecting to

• The type of survey mark to place – what kinds of survey marks are suitable for long term control?

2. Once you have designed an appropriate control layout for the site, write a field procedure document to be provided to any surveyor that will be going out on site to place and measure the control marks.

(30 marks)

Include information about:

• Any of the considerations from above that they will need to confirm on site

• Equipment to be used

• Measurements to be made and method of collection

• Checking process to confirm quality of data

2.2.3. Task 3 – Project preparation [50 marks]

Before you go out on site to begin the field work for the project, you take the instrument out to the Caboolture Calibration Range to test and adjust your instrument. You complete the data collection and come back to the office to process it.

Before you start processing the calibration data, there is something you need to fix. You forgot to set the correct temperature, pressure and humidity in the instrument before making the observations to the first target, so you need to adjust the 5 measurements made to that target.

Table 2 below shows the atmospheric data that was already in the instrument that was used, as well was the atmospheric values that should have been entered before taking the first five measurements. The incorrect distances recorded to that target are documented in Table 3.

Table 2 Atmospheric Conditions: entered and true at time of measurement Pillar 0 to Pillar 1

Atmospheric Data Incorrect value Correct value

Temperature 19°C 27°C

Pressure 990 mbar 1240 mbar

Humidity 50% 70%

The instrument manufacturer uses the following formula to calculate the appropriate atmospheric correction for ambient conditions:

???1 = 286.34 - [0 (.129525+ ????)?? - 4.126(1 +×????10)-4h × 10??]

where ?D1 Atmospheric correction (ppm)

(30 marks)

4. Check that the instrument is working to manufacturer’s specifications by creating a Verification plot. Comment on the conclusions you can draw from the Verification plot and what you can do about them.

(10 marks)

The instrument manufacturer’s specifications for EDM Standard measurement to a standard prism is +/-(1mm +1.5ppm).

2.2.4. Task 4 – Levelling [40 marks]

Being a diligent surveyor, you complete a check level traverse between the existing survey marks to see how they fit within themselves before using them to transfer levels to the project site.

The data from the level traverse is shown below in Table 6. It was completed to control traverse standards, using appropriate equipment. As much as possible, the traverse was on a direct line between survey marks.

From the coordinates provided in the Survey Control Reports, the straight-line distances between each of the marks are:

2.6. Appendix C – Links to Survey Control Reports

Survey Control Reports are reports containing the registered information in a Queensland

Government data base. These reports are free for all to access, either through Queensland Globe or other search options.

The first page contains the administrative (number, location, etc) information, the details of the mark (mark type, installation date, etc) and the co-ordinate information for the mark (co-ordinate values, elevation values, uncertainty, datum, etc).

When assessing the level run, consider the uncertainty of the of control mark as well as the method by which it was fixed (how was the elevation transferred to the mark). This can tell you whether a mark may be more reliable than another. The lineage attribute tells you whether the mark is directly on the datum, or whether it is a secondary connection to datum (for example, with AHD values, they can be on datum - i.e. connected directly to a mark that was used to establish AHD datum; derived - which means they connected only to a mark that already has an AHD value, but not necessarily a datum mark; Main Roads - Qld Government department for roads - most roads departments seem to have their own datums that all the marks they place for state-controlled roads are on; or a local datum).

1. Generic Assignment Information

1.1. Introduction

This assignment takes the skills and knowledge you have gained from Modules 4 onwards and combines them into a survey project scenario for you to work through. Keep in mind that this is an assessment of what we are learning in this course, so some liberties have been taken when designing the scenario to ensure it remains at a level suitable for this course.

It is not intended to be a comprehensive exercise in survey projects, nor is it intended to 100% accurately reflect normal work procedures – we’re only first year surveying!

1.2. Assignment Summary

This assessment contributes to 25% (250/1000 marks) of your final grade for this course. Table 1 below shows a summary of the marks for each question and how it relates to the course content. Table 1 Summary of marks per question and links to course content

Please also confirm the due date in the Course Specifications.

1.4. Late penalty

A late penalty of 5% (12.5/250 marks) per whole, or partial, University business day that the assignment is handed in after the due date, without prior application for omission of late penalties.

For more information regarding the University standard for assessment, due dates, and late penalties, please see the University Procedure for Assessment.

1.5. Assignment presentation guidelines

This assignment is predominantly a surveying mathematics exercise. As this is a first-year course, your submission may be neat hand-written solutions, typed solutions, or a combination of the two.

Ensure your name and student number appear at least once in the body of your assignment (preferably on the first page).

Label each Task or sub-task clearly, so your solutions are easy to follow.

For repetitive calculations (i.e. columns of values that use the same formula), you may use a spreadsheet program to generate the values required, however, you should provide a sample calculation for each column/row as required.

1.6. Submission Instructions

All submissions should be digital and made through the StudyDesk Assignment submission link.

Before submitting your assignment, check the file you are submitting – are all the pages legible? Have any images/scans been accidentally cropped? Are the pages in the correct order? Have you got copies of the same page, or pages missing?

If you do not have a scanner at home, Adobe makes a free mobile scanner app that uses your mobile/tablet camera to take scans of documents and converts them to PDF. It is very easy to use and produces clear results. There are probably other scanner apps out there, but at this one has the benefit of being from a trusted source.

A submission checklist is included as Appendix A.

Use the following naming convention for your files:

o SVY1104_A2_[SurnameInitial]_[StudentNumber].xxx

o Where [SurnameInitial] is replaced by your surname and your first initial (eg Jessica

Smith would be SmithJ); and o [StudentNumber] is replaced by your 10 digit student number (eg 0061234567)

2. Assignment Body

2.1. Introduction

Your company has just landed a large project to be the project surveyors and designers for the development of a parcel of land. You will be one of the lead surveyors for the project, so you are going to be heavily involved in both the design and the construction phases.

The planner has provided your company with the first draft of the site design, but it is your job to calculate the design to ensure it fits within the boundaries of the lot and that there are no miscloses in the proposed roads.

You will also be entrusted with managing the survey control for the site, which means you will need to design and place any marks required for the life of the project. Of course, you will also be involved in the field work for the project as well, so you need to ensure your equipment is fit for purpose.

2.2. Assignment Questions

The project site is Lot 71 on SP 291400, close to the train station in Springfield Central, Queensland.

Please see 2.5 Appendix B for a map of the site, including existing survey marks in the area.

2.2.1. Task 1 – Site design [120 marks]

The client has provided you with a draft design (see Figure 1) which you will need to calculate and check for errors. In the southern half of Lot 71 a new boundary is to be created, as shown in blue dimensions. Check the close of the southern lot enclosed by the existing boundaries and the proposed new boundaries.

1. Use Bowditch Adjustment by Vector to distribute any misclose in the proposed boundaries.

(30 marks)

2. If this new boundary were a traverse, would it have been appropriate to adjust the lines, assuming the traverse was of a normal standard? What would you recommend doing to improve the traverse if it were not suitable?

(10 marks)

Figure 1 Proposed boundaries for southern lot and dimensions for new cul-de-sac.

There will also be a new cul-de-sac built for the development. It will come off perpendicular to the existing stub road (180°00, 6.53) into the lot and be designed to fit the dimensions shown in Figure 1.

Assign 0m chainage to point A and increase through to point H, along the straight and curved lines. This chainage is applied to the perimeter of the cul-de-sac (not the centreline, as it would normally be). The intersection angle of curve CP3 will be close to 90°.

3. Calculate the perimeter of the cul-de-sac.

(40 marks)

4. Assuming you are set up at the common tangent point between the two 10m radius curves, calculate the setout bearings and distances for the even 10m chainages around the perimeter of the cul-de-sac, as well as all the tangent points for each of the three curves.

(40 marks)

2.2.2. Task 2 – Control design [40 marks]

1. Now that you have the design for the site finalised, you are able to look over the site and come up with a proposed site control design.

(10 marks)

Of course, a desktop design cannot be finalised until a site visit, but this is a starting point to work from.

Some points to consider when deciding on the locations for the control marks:

• Likely line of sight between marks

• Limit the distance between marks to 150m or less (use the measurement tool in Qld Globe to approximate)

• Forward plan the project and try to place internal marks away from areas where they are likely to be knocked out early during construction (so not in the roads, for example)

• Ensure you have good geometry – don’t load all the marks to one side or one corner

• Make sure there is control around the outside of the site as this is likely to survive, allowing you to place new control as required

• Which existing marks you are connecting to

• The type of survey mark to place – what kinds of survey marks are suitable for long term control?

2. Once you have designed an appropriate control layout for the site, write a field procedure document to be provided to any surveyor that will be going out on site to place and measure the control marks.

(30 marks)

Include information about:

• Any of the considerations from above that they will need to confirm on site

• Equipment to be used

• Measurements to be made and method of collection

• Checking process to confirm quality of data

2.2.3. Task 3 – Project preparation [50 marks]

Before you go out on site to begin the field work for the project, you take the instrument out to the Caboolture Calibration Range to test and adjust your instrument. You complete the data collection and come back to the office to process it.

Before you start processing the calibration data, there is something you need to fix. You forgot to set the correct temperature, pressure and humidity in the instrument before making the observations to the first target, so you need to adjust the 5 measurements made to that target.

Table 2 below shows the atmospheric data that was already in the instrument that was used, as well was the atmospheric values that should have been entered before taking the first five measurements. The incorrect distances recorded to that target are documented in Table 3.

Table 2 Atmospheric Conditions: entered and true at time of measurement Pillar 0 to Pillar 1

Atmospheric Data Incorrect value Correct value

Temperature 19°C 27°C

Pressure 990 mbar 1240 mbar

Humidity 50% 70%

The instrument manufacturer uses the following formula to calculate the appropriate atmospheric correction for ambient conditions:

???1 = 286.34 - [0 (.129525+ ????)?? - 4.126(1 +×????10)-4h × 10??]

where ?D1 Atmospheric correction (ppm)

1. Calculate the correction to be applied to the measurements to correct them for the ambient conditions at the time of measurement.

2. Calculate the average of the five corrected distances to use in the calibration processing

3. Calculate the Scale Factor and Instrument Constant for the instrument/target pair using linear regression.

(30 marks)

4. Check that the instrument is working to manufacturer’s specifications by creating a Verification plot. Comment on the conclusions you can draw from the Verification plot and what you can do about them.

(10 marks)

The instrument manufacturer’s specifications for EDM Standard measurement to a standard prism is +/-(1mm +1.5ppm).

2.2.4. Task 4 – Levelling [40 marks]

Being a diligent surveyor, you complete a check level traverse between the existing survey marks to see how they fit within themselves before using them to transfer levels to the project site.

The data from the level traverse is shown below in Table 6. It was completed to control traverse standards, using appropriate equipment. As much as possible, the traverse was on a direct line between survey marks.

From the coordinates provided in the Survey Control Reports, the straight-line distances between each of the marks are:

2.6. Appendix C – Links to Survey Control Reports

Survey Control Reports are reports containing the registered information in a Queensland

Government data base. These reports are free for all to access, either through Queensland Globe or other search options.

The first page contains the administrative (number, location, etc) information, the details of the mark (mark type, installation date, etc) and the co-ordinate information for the mark (co-ordinate values, elevation values, uncertainty, datum, etc).

When assessing the level run, consider the uncertainty of the of control mark as well as the method by which it was fixed (how was the elevation transferred to the mark). This can tell you whether a mark may be more reliable than another. The lineage attribute tells you whether the mark is directly on the datum, or whether it is a secondary connection to datum (for example, with AHD values, they can be on datum - i.e. connected directly to a mark that was used to establish AHD datum; derived - which means they connected only to a mark that already has an AHD value, but not necessarily a datum mark; Main Roads - Qld Government department for roads - most roads departments seem to have their own datums that all the marks they place for state-controlled roads are on; or a local datum).
