CERTIFICATE IV BUILDING (3477)

MODULE THREE – SITE CONTROLS

ASSESSMENT TASK No. 1

TASK 4- SITE SURVEYING AND SET OUT

Case Scenario:

The Original intention was to subdivide the block. However the owners have decided to leave the block as it is, move the garage to the western side of the block facing Bell Street.

Although the block is large (1400m²) and appears to have a lot of space, the block has a lot of trees along the western border (which the owner does not want removed) and directly behind the existing fibro garage. The trees on the northern (back) and eastern side (Church St) of the block are
not
to be removed. Scattered around the block are various size Jacarandas and small shrub trees.

1) Provide a step by step procedure to set up and use the automatic/laser level to calculate the RL (Reduced Level) from the set datum point.

2) From the drawings provided transfer the levels shown on the drawing onto the RL Grid indicating the fall of the land. (i.e. That is to show a graph of the fall of the land in a cross section format).

3) Draw in the grid (showing correct measurements) where you would position a free standing double garage with a concrete slab (assuming the existing garage has been demolished). The garage is to be located closer to the western boundary facing Bell Street – incorporate the side and front boundary set backs.

Assume your own design and measurements for the garage.

4) Determine the volume (m3) of the cut/fill required for the site.

Using the Cut & Fill Grid provided, sketch how much cut and fill is required to level the slab area of the garage.

5) Complete a written report to the client, providing a detailed description of why it is necessary to cut and fill and remove some of the trees. The report must be clear and concise to justify the costs of the excavation.
