Elements and Performance Criteria
- Set out a T-shaped or L-shaped building on a selected site with minimal profiles.
- Site information and dimensions are identified from site plan and checked against plan drawings.
- Survey pegs are measured to ensure correct identification occurred before pilot pegs are positioned.
- Profiles pegs are set up on site at a working distance from pilot pegs and parallel to pilot line.
- Marks to indicate outside of building or other structural members are made.
- Prepare and test levelling devices.
- Operate levelling devices.
- Identify specialised levelling and surveying equipment available on large building projects for various set-out and checking procedures.
- Compute coordinates and bearings, distances related to grids and general set-out work on large building sites.
- Angular relationship between different bearings (whole circle) is demonstrated.
- Bearing and distance between coordinates are calculated.
- Coordinates of a point given the bearing and distance from a point with known coordinates are calculated.
- Offsets from a coordinated point given the bearing and distance from a point with known coordinates are determined.
- Information necessary to set out a structure using a site plan is determined.
