What you have to do For this assessment, you will require the Project 1 documentation. The questions in this assessment relate to 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.

Please type your answers in black font. (Calibri 12 point) 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? it is

roughly true, since we only have 500 mm rise between this two corners 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) the exact dimension between these two points considering Pythagoras’ theorem would be (43.866^2-0.5^2)^(1/2) = 43,863 mm 2.

You have engaged a surveyor to carry out an identification survey of Lot 14 (peg the four corners of the boundaries) 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 the distance from north west point is 6216 mm and the angle between north side of allotment and north west corner of the building is 15° 8' 55" b) From the contours determine the total fall across the footprint of the building 250mm c) Assuming you will construct a level, rectangular platform for the construction of the building, extending 1m beyond the external walls of the building, what are the approximate dimensions of this platform? 10.45 m x 7.94 m

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. The outcome of surveying is the four corners of allotment

and a corner of to be built building, lets assume the it is the north western one. Now we want to set out the south western corner. Using a tape measure and string lines you can set out the extent of building step by step. See below for a couple of first steps. Please keep in mind that in order to have room for construction, we are better to offset our string lines for 1 meter from actual building boundaries.

e) Outline how you would construct the formwork to achieve the required Finished Floor Level. Prior to formwork construction, bulk excavation is essential. Then we should undertake trim and sand filling to achieve RL of finished floor minus slab thickness. 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). Using the mark

up below, we can work out bulk excavation as per following spreadsheet.

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)

b) Determine the grade from the top of the crossing to the bottom of kerb as a percentage and a ratio. 3.125% or 1/32

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) WxLxH = 2.5mx5mx2m. We should offset 500 mm from the boundary

fencing/walls the excavate the pit. FYI, W is parallel to W-E boundary and L is parallel to N-S boundary

NOTE: This is a competency-based assessment. You will receive a result of Satisfactory or Unsatisfactory. This means that you must satisfactorily complete each question (or part thereof) to meet the competency requirements set out in the training package. If you do not meet the competency requirements, you will need to resubmit your assessment until competency is achieved.
