A developer $($client$)$ has recently bought Erf $5638,$ Lephalale Extension $70.$ He$/$ She has

appointed you as the Surveyor to carry out the survey on the said portion of land. He$/$ She

plans to build a triple storey building with a basement and floor coverage of about $45\%$ and a

parking bay of about $20\%.$ One of the specifications is that the basement should be supported

with pillars that are at least $10$m apart. Facility manager has done a projected life cycle costs

analysis on the proposed plan and the building is expected to last for at least $50$ years. The

area has a fully functional municipal bulk services and you have been requested to take those

into consideration. The client is not so concerned about height $($Z$)$; however, he$/$she is more

concerned about the Y$,$ X coordinates and they should be within the grid. You can always

determine your own elevation $($Z$).$ The reason why the client is concerned about Y$,$ X is that

the proposed structures should be within the building line which is $5$m and to avoid factors

pertaining encroachment. The survey was done on the $30$th of August $2023,$ TrigNet was down

on that day and you could not connect to the system. Luckily, you managed to identify two

boundary beacons $($as indicated on Annexure A$)$ and you have decided to use them as your

control points. You decide to visit the site on a different day to verify the beacons using a

GNSS$/$Total station and calculated data $($coordinates$).$ Use your precise survey skills to

address the following:

$1.$ Calculations $($beacons and setting$-$out coordinates$)/$ Raw data

$2.$ Identification of instruments to carry out the survey

$3.$ Plan of a detailed survey $($site survey$)$

$4.$ Establishment of control points $($BM and deformation controls$)$

$5.$ Positioning of the structure and parking bay $($coordinates$)$

$6.$ Trigonometric heighting $($if necessary$)$

$7.$ Aerial imagery as background $($source it at CD: NGI$)$

$8.3$D model for scanner $($outlined steps and procedures$)$

$9.$ Beacon coordinates, setting$-$out coordinates, control points $($BM$/$Deformation$)$ should

be on excel and pdf
