CPCCBC5006B Apply site surveys and set-out procedures to medium rise building projects

Assessment Task 1

You are required to work through these questions and submit your answers.

1. Set out a T-shaped or L-shaped building on a selected site with minimal profiles.

1. Explain how you would go about identifying site information and dimensions from site plan and checked against plan drawings.
2. Explain how survey pegs are measured to ensure correct identification occurred before pilot pegs are positioned.
3. Explain how profiles pegs are set up on site at a working distance from pilot pegs and parallel to pilot line.
4. Explain how marks to indicate outside of building or other structural members are made.

2. Prepare and test levelling devices.

1. Explain how various components of levelling devices are identified.
2. Explain how basic tests on levelling device accuracy are performed according to manufacturer specifications.
3. Explain effects of maladjustment in levelling devices are identified and recorded according to standard operating procedures.

3. Operate levelling devices.

1. Explain how temporary adjustments to set up levelling equipment are carried out in accordance with standard operating procedures.
2. Explain how horizontal and vertical angles are determined using levelling devices.
3. Explain how site is set out to specifications using levelling devices.

4. Identify specialised levelling and surveying equipment available on large building projects for various set-out and checking procedures.

1. Explain the differences between several types of specialised surveying equipment are researched and recorded.
2. Explain how the survey of each level checked for vertical accuracy of 10mm using two levelling devices is carried out.

5. Compute coordinates and bearings, distances related to grids and general setout work on large building sites.

1. Explain how the angular relationship between different bearings (whole circle) is demonstrated.
2. Explain how the bearing and distance between coordinates are calculated.
3. Explain how the coordinates of a point given the bearing and distance from a point with known coordinates are calculated.
4. Explain how offsets from a coordinated point given the bearing and distance from a point with known coordinates are determined.
5. Explain how the Information necessary to set out a structure using a site plan is determined.
