CPCCSV5007A: Assessment 4
What you have to do
For this assessment, you will require the Building Surveying Project 1 documentation (house project plans). The questions in this assessment relate to Building Surveying Project 1.

How you will be assessed
The questions in this assessment cover a number of areas within the unit of competency
You will need to show that you are competent across all the areas contained in this assessment.
YOU MUST show all workings where you have done calculations.

Questions
1.    You have taken a measurement on Lot 14 from the south west corner to the north east corner of the allotment. The measurement you obtained from your tape measure, laying it on the ground, was 43,866 mm, measured to the nearest millimetre.
a)    Is this the true dimension for the distance between the two pegs on plan view?
b)    If the answer to part ‘a’ is no, what is the true dimension on plan view and explain the reason for the difference? (use Pythagoras’ theorem)
If the answer to part ‘a’ is yes, explain your conclusion.
(10 Marks)
2.    You have engaged a surveyor to carry out an identification survey of Lot 14 (peg the four corners of the lot) and to peg the 6m building line (the setback of the house from the front boundary).
a)    From the north west corner of the allotment, calculate the angle and distance to the north west corner of the proposed building                    (10 marks)
b)    From the contours determine the total fall across the footprint of the building
(5 marks)

c)    Assuming you will construct a level, rectangular platform for the construction of the building, extending 1m beyond the outer most external walls of the building, what are the approximate dimensions of this platform?                (5 marks)
d)    Utilizing the surveyors pegs, outline, step by step, how you would set out the building using profiles and string lines to allow any excavation, formwork/slab construction to be accurately completed.                            (10 marks)
e)    Outline how you would construct the formwork to achieve the required Finished Floor Level.                                        (5 marks)

f)    From finished floor level shown on the drawings (RL 0.000), subtract 200mm to allow for the slab and sub grade thickness. This reduced level is sometimes referred to as the bulk excavation level (BEL). From this BEL, the contours, and the dimensions of the rectangular platform, calculate the approximate volume of the bulk excavation for the building (use diagrams where needed to illustrate your method).Hint: You will be calculating from the rectangular shape in Q 2 c.                 (10 marks)

3.    Assuming the RL at the top of the vehicle access (crossing) is 0.030, the top of kerb is   (-0.030) and the kerb height is 100mm,
a)    Draw a longitudinal section of the vehicle crossing from the kerb to the front boundary Lot 14. (Note that the length of the crossing is 3.2m; determined by scaling off the drawing)                                (10 marks)
b)    Determine the grade from the top of the crossing to the bottom of kerb as a percentage and a ratio.                            (5 marks)
4.    The client on Project 1 has requested provision be made for storm water detention on the site. The hydraulics engineer has calculated the capacity of the pit necessary for the site to be 23,000 litres.
Calculate a pit dimension that would meet this capacity requirement and that can be constructed within the front area of the property; that is, in the area between the front boundary and the front building line. Do not position the tank within 3m of the building.  (1000L = 1m3) Hint: Consider the implications of making the tank deeper than 2m.
(10 marks)
5.    The floor slab of a carport on a sloping site is to have an RL of 14.235.  At the front boundary, 11.68 metres from the carport, the RL is 15.987

a)    If the driveway is to have a constant grade from the boundary to the carport, what will this grade be?
Express your answer as a percentage and as a ratio.              (5 marks)
b)    Council requires that the maximum change in grade at any point is 12.5% with any section of driveway with constant grade being at least 2.0 metres in length.  Redesign the driveway using an initial grade from the boundary of 10% for 2.0m and a final grade (entering the carport) of 8% for 2.0 m.

Indicate all distances, RLs and grades on a sketch.                (10 marks)
c)    What is the grade of the middle section of the drive?
Does it comply with the maximum allowed by council of 20%?        (5 marks)
