INTRODUCTION:BackgroundThe purpose of this report is to focus on all aspects of surveying practical field work that was carried out on the trip to Bournemouth during the five days there (1st 5th of November 2010). Throughout the five days there all the instruction were given on Monday and different tasks were set from Tuesday to Friday carrying one task each day whilst noting the result and calculating pertinent data to check the accuracy and precision of the task. However the report will also emphasis on different aspect for example, problem within the team, precision achieved and adequacy, practical problems knowledgeable and how they were dealt with and never the less weather conditions and time constraint and there effects. Objectives Working as part of a group of four students to carry out different Civil Engineering surveying tasks Ensuring that tasks are carried out to a high standard and limiting amount of errors and misclosures. Preparing calculations beforehand and sketching relevant figures according to the task to be carried out the following dayScenarioA developer wants to build a new leisure complex overlooking the sea on the area currently grassed at the top of West Cliff, and requires details of the existing features in order to determine the how much material would need to be removed in order to achieve a flat base. The development will also extend onto the beach, where the developer would like to build luxury beach houses for the clients and needs some idea of how much space they would take up. To avoid tidal drift of the sand, there is also the requirement to construct new breakwaters on the beach at a constant interval between the existing breakwaters, to protect the new beach houses. To determine the requirements for the scheme, there are FOUR tasks that need to be completed, as follows:

TASK A: TRAVERSE TASK B: VOLUME DETERMINATION TASK C: SETTING OUT HORIZONTAL TASK D: SETTING OUT VERTICAL and LEVELLINGPicture 1: This is the plan view of the site where all tasks were carried from.

Picture 2: Welcoming of Bournemouth. METHODOLOGY: Task A: Traverse.

ADCB89.05158.66732.02033.591 The main aim of this exercise was to set up a control traverse around the site at the top of west cliff. The traverse has four different points around the area given, and each student took three sets of angel at different point. At each station the readings were taken carefully recorded and making sure the instrument doesnt move or the bubble goes off set. Finally the traverse was computed including information on partial coordinates, misclosures, and linear errors and corrected (Bowditch) final coordinates; however the measured angel had to be within tolerance of +/-20.

Figure1: traverse

Task B: Volume Determination. The main aim of this exercise was to determine the amount of soil needed to be excavated at the area allocated as well as the volumes of soil involved in grading the siteBefore the task was carried out each and everyone in the team had to sketch the area given and to determine the best suitable point to set up the instrument were all the area can be best seen (visibility of whole area) without distraction of trees and in our case (the beach house) that was on the side of our working area. Square grids of 10X10 were set all across the area using tape and flags to mark the points. Unequal areas were then measured using offsets and calculated separately at the end. Each student then was able to take the readings and record data of different points of height using the instrument (total station).

BCDEF123456Figure2: Volume determination

Task C: Setting out horizontal.The main aim of this exercise was to set out a beach house with bay window overlooking the sea.Time consuming was critical for this task hence why the instruction was given to all students beforehand and required to do all the calculation and sketch before arriving on site. After arriving on site before taken the instruments had to be checked and insure all the equipment was doubled checked as the area we were to undertake the task was far from where the van is (where we collect equipment). The instrument was then set in the middle of out point, then 3m offset to the promenade was made and point W1 is where the total station was set using the co-ordinates of easting and northing to be 0.00. The line parallel to the promenade was given a bearing of 270 and to get the points of the beach house the total station was used using the results already calculated beforehand. Deflection angles and distances along the curve of the 2m intervals were set using the total station and the tape measure. Base line at each point and diagonals lines were also measured using total station. After completing the task the group members checked each point to double check the accuracy before calling a supervisor to measure and checked its all correct.

Picture 3: Setting out horizontalTask D: Setting out vertical.The aim of this exercise was to set out a new breakwater line along the beach. A perpendicular line was set up from the promenade, the ranging rods were then placed 5m intervals from the promenade using Pythagoras theorem. 5m10m15m10m5mFigure 3: Setting out Vertical

After setting out the first three rods using Pythagoras theorem the other two rods were then measured by tape from the 3rd one at 5m intervals making sure there lining up with the rest. The group members were then able to take the heights from benchmark to the point of start at the promenade, transferred taking height of ranging rods as intermediate sights. Knowing the gradient of 8 the height at 5m intervals was then calculated and plotted using sliders to attach to the roads. After the setting out on the beach exercise finished and checked by supervisor the group members were then able to pack some equipment away and worked our way up on to the zigzag way to take reading to the GPS point which was set at the top of the west cliff.

Picture 5: Prism set upTask B: Volume determinationTo be able to remove soil in any land the volume of the land has to be taken into account hence why we done this task to show that this is done in everyday work force in order to have a flat land for a building or any type of structure to be built on. As the land was not flat and had little hills of ups and downs the better way for these problems, in this case this exercise shows how to deal with such a condition.

After all the setting out was complete and ready to be observed by the supervisor, all of the length, width and diagonals were then double checked and recorded by the supervisor. The values recorded by the team members were as followed:

Figure 9: Ranging rod gradientUsing the formula (Distance x tan in our case) enabled to work out each poles position where the slider was attached to 5 tan ( = 0.703 10 tan ( = 1.405 15 tan ( = 2.108 20 tan ( = 2.811

Finding the height difference between ranging rods was calculated as followed: 2.827 2.769 = 0.058 2.769 2.497 = 0.272 2.497 2.293 = 0.204 2.293 2.073 = 0.22

To find the height of the slider on the ranging rod was simply done by the height of gradient which is 8 is subtracted with the height difference of the rod

0.703 0.058 = 0.645 1.405 0.272 = 1.133 2.108 0.204 = 1.903 2.811 0.22 = 2.591

The 1st rod near to the promenade could not be fitted with the slider simply because the rod length itself which was around 2m 2.5m, the more you push the rod onto the sand the lesser the value you end up with as a remain. The value 2.591m represent the gradient which is over the maximum size for the rod hence it could not be put on. After the completion on the task the exercise was then had to be carried on and at each rough point the readings of back site, fore site and intermediate had to be recorded all the way up the zigzag until where the point of GPS was located.

Picture 8: Beautiful view of the beachTask a: Traverse

This task was one of the best task that we all liked as every group member had to take readings at one point and been observed by the supervisor, this task went really well and we got there and got on with it with no problem however, the difference in angle was 40 which was very good as it was within the acceptable tolerance.

Problems faced by team membersFrom my opinion, this task went really well all the team member contributed with the work fairly and we all got on really well, at start the group was going bit slow but it eventually speeded the process up and were then able to get on and finish the task with no problem.

Precision achieved and if it was acceptable or not:The angle difference achieved at the end of the task was 40 which was acceptable; however the misclosure was a bit more than expected this was simply because of the clear vision due to the presence of the beach shed (sitting area) and the trees as we was given one of the hard area to work on. Cautious had to be taken into consideration while setting up the total station due to the fact that the ground was not flat and also when holding the prism, to ensure clear visibility whilst taking the readings however some of error accrued when the reading was taken and it was blurry vision due to the weather condition. If I had to do it again, what I would do differently:

If I had the opportunity to do the tasks again I would make sure I have printed off all the relevant notes to take with me and i would also make sure I revise and go through the task the day before i carried out the task, I would also print all the calculation sheets that are required to take the results in this will reduce the error of miss writing the numbers. Another thing that I would do is not to stay with friends up all night and talk but to try and have early sleep which will defiantly help me to be more awake and concentrate more and also to have breakfast before coming to site. An indication of time and budget constraint and how they affected the tasksLuck of preparation has affected the start of the task and also not having the right sheet to record our result in meaning when the group got there first thing we did was to sketch and made a table up using line paper, however debating and talking was also one of the things helped to waste time instead of getting on with the task and do it.

How team members adapted to the weather conditionsThe group adapted to the weather quite well as all group member had warm clothes to wear for example, gloves, hats, jumpers and even water proof jackets and high visibility jackets as required at all times.

ConclusionOverall the task went really well everyone put effort into it and wanted to get the task over and done with but as accurate as possible, this task teaches us how to set up instrument when wanting to undertake a task or a project as angle and distance are vital information to have before starting any construction. This exercise given to us is very useful in the future time as we graduate and hope to get a job we can end up in any construction company which are involve in surveying and knowing this now can really help when it comes to real outside world i.e. work as this task was carried out will be nearly enough the same as the one the employer would ask you to do. I have really enjoyed traverse and I can also see myself doing surveying as a career.

Task B: Volume determination: This task was definitely the most challenging task for our group, as the arear given was a complex type and objects blocking the view it was very difficult to get clear of the whole view of the land.

Problems faced by team members

Having no knowledge of the task undertaken the group members have struggled to set this task for the first hour or so, however as it was the first time for group members to use the instrument this also took time in start taking our readings, at one point the instrument did not pick up any signal at all until the supervisor came to check it out and also gathered to know that there was a faulty with the instrument hence why another instrument was provided.

Precision achieved and if it was acceptable or not:As this task did not have a limit tolerance set by the lecturer the volume had to be compared by other group member who work on the same spot in our case the green point to whether or not the volume at the end of calculation were near enough the same or not, in this case as the result were compared the result were nearly the same with other group which indicated that it was correct.

If I had to do it again, what I would do differently:

Given an opportunity to do the task again, the team have to be more prepared and to also come on time, the total station would be one thing that the team should check to see if any faults can be picked up, less talking and more working and concentration would probably the best solution to get on with the task.

An indication of time and budget constraint and how they affected the tasksThe total station had a big impact on the task and really postponed the completion of the task having weak signal and not able to pick up any signal at all after setting up the total station it had then have to be removed and placed it with a different one which then it also had to be sated up second time. However, the weather also delayed the group progress as it was windy and showers

How team members adapted to the weather conditions

The group adapted to the weather quite well as all group member had warm clothes to wear for example, gloves, hats, jumpers and even water proof jackets and high visibility jackets as required at all time as it was so windy and showers of rain.

ConclusionAs last year student done assignment for construction method and one of the criteria was to explain about excavation, when did the assignment it did not really go to my head completely, but as i have done the practical side this really gave me a big knowledge of how this process works, as now understanding of filling and excavation is a bigger knowledge it can also be applied to a work environment.

Task C: Setting out horizontal

This task didnt really go the way the group wanted it to go, even though the calculation and sketch was done before hand few problems accrued during the task.

Problems faced by team members

Problem within the team has coursed a major difficulty as a group work and effected some task that was carried out, few points that shows this is the case were:

Some group members were always turning up late therefore we start late and finish late. Some group members were not putting effort into the work leaving few people to do the work instead of all as a group. Some group members were on the phone or talking to friends during the task. Arguments during tasks which lead to time wasting. Weather condition was also a major part to the group as it increases the result error by significant amount.

Precision achieved and if it was acceptable or not:From looking at the result done in advance and note down on the paper, and comparing it with the task done at the practical side we can see that the results are exactly the same therefore the results achieved in this task was well done, on other hand the curve accuracy was definitely within the satisfactory boundary thus the task went well.

If I had to do it again, what I would do differently:

If the task was given again I would go over the lecture notes over and over again until I was 100% sure of what to expect and if theres any chance of error occurring how I would coupe with it. Doing the calculation more once also builds up my confidence of doing any task so I would do the calculation twice. Doing this task with less wind will definitely reduce error from happening. Also taking more care and time with doing the work will help achieve more accurate result. I would strongly recommend for anyone to have some sort of glasses to stop sand blowing in their eyes this has gave me a major problem as it was windy and sand flies everywhere.

An indication of time and budget constraint and how they affected the tasksThe total station had bit of a problem picking up signal from the prism it read weak signal this was due to the bad weather condition, IF the student were provided with weather proof equipment such as the total station this will speed up setting out and also give very accurate reading, however the cost of weather proof instruments are taken into consideration hence we dont have them at university.

How team members adapted to the weather conditions

The group adapted to the weather quite well as all group member had warm clothes to wear for example, gloves, hats, jumpers and even water proof jackets and high visibility jackets as required at all time as it was so windy at the beach. This teaches us on what to expect while working for a company and to get the job done no matter the weather condition and to make sure there is no excuse for result error, as elaborated no check no cheque

ConclusionOverall the task went well everyone in the group member ended up in putting the effort in to avoid big error, time was tackled really well as the calculation was done the day before, however the result werent as we wanted them to be this was due to a very windy day this had impact in overall result. This task has really gave the taste of how its like to set up the beach house or even any other structure possible as it would be same procedure, communication with neighbour group and borrowing equipment such as tape measure has really helped in getting the work done quickly and effectively. There is defiantly a big lesson learnt from this task in many different ways. This task will come in hand in many different construction engineering such as tunnelling and highways.

Task D: Setting out vertical

The final task that the group undertake was the setting out vertical, this task was very skilful and handy to know, and Pythagoras theorem was used to determine the distance and the straightness of the break water, this was very critical to get it as straight as possible.

Problems faced by team members

As always team member turning up late was one of the problems with getting the task started on time, but once the task began all team member were motivated and started to enjoy taking reading, the problem that stressed the team the most was the wind as by taking the result from the zigzag the staff had to be opened all the way reaching about 5m, when it was all extended the staff kept moving, hence we had to rock it backs and forwards and take the lowest reading. However, after all the team worked extremely hard with great enthusiasm

Precision achieved and if it was acceptable or not:Final misclosure was 63mm this was not within the tolerance required, however due to lack of time and very strong windy condition we were advice by the lecturer and were explained the reason for how it might have been slightly off, taking into consideration the GPS finish point was itself an error of 3to4mm out.

If I had to do it again, what I would do differently:

If the opportunity was there to have another chance of doing the task I would defiantly make sure that the task was started on time with much knowledge about the task, holding the staff at exactly 90degree is very critical in this case as every error obtained in one reading adds on and this builds up to a bigger error of misclosure. Another thing that I would definitely do is using change plate all the way through as I think this will reduce the error.

An indication of time and budget constraint and how they affected the tasksWeather condition had a really big direct impact in our task, the wind was very strong and blew the staff side to side so therefore at some point the team had to wait a bit for wind to reduce its pressure and carried on in taking the readings.

How team members adapted to the weather conditions

The group adapted to the weather quite well as all group member had warm clothes to wear for example, gloves, hats, jumpers and even water proof jackets and high visibility jackets as required at all time as it was so windy at the beach and throughout the zigzag pathway.

ConclusionOverall the task went really well, the skilled learn from this task was very helpful to use in university practical classes and even in the real world of work. This exercise can be related when setting out drainage systems which use the same process of finding the gradient.

Overall Conclusion:

Everyday practical classes for surveying are done at the university site, the areas where the task are carried out are not significant and having the building surroundings the weather is not as strong as an open field thus why not enough knowledge is gain, nevertheless the Bournemouth surveying field trip has really teaches and show each and everyone how it feels to work in real life work. All four task that were taken by student were really useful skills to have in the future not only did it teach student surveying but it also teach us so many different aspects such as; Working in a team, communication skill, time management, leadership skill and many more. This trip will be recommended to any student studying engineering
