Question

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).
From the north west corner of the allotment, calculate the angle and distance to the north west corner of the proposed building
From the contours determine the total fall across the footprint of the building
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?
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.
Outline how you would construct the formwork to achieve the required Finished Floor Level.
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).​
