Setting Out for Construction - Learning Objectives

1.0 Levelling
1.1 Basic levelling terminology and principle
1.2 Basic level survey including checks
1.3 Two Peg Test (Including how to adjust collimation error).
1.4 Transfer a TBM in a closed loop using correct booking methods
1.5 Calculation checks on TBM Field Data
1.6 Calculate Acceptable Error for number of Set- Ups and compare to TBM Field Data
1.7 Set blinding pins to correct level.
1.8 Set and check the level position marked on a vertical surface (fence post, wall)
1.9 Inverted Staff Reading including correct booking and checking methods

2.0 Profile Boards
2.1 Determine levels from drawing and construct profile boards at 1m offsets for reinforced concrete strip foundations.
2.2 Interpret construction drawings, carry out calculations and construct profile boards for a sloping excavation i.e. drainage run

3.0 Batter Rails
3.1 Interpret construction drawings and set out batter rail positions for an excavation for a deep circular reinforced concrete base for a tank below existing sloping ground.

4.0 Tape Measure
4.1 Interpret construction drawings and set out gridlines for steel framed building foundations using steel tape and string lines. Take account of sloping ground.
4.2 Set out 1m offset pegs for building corners.
4.3 Set out batter rail positions for excavation for a deep circular reinforced concrete base for a tank on existing sloping ground.

5.0 Total Station – Set Up and Basic Checks
5.1 Set up target and total station over a fixed point following the recommended procedure.
5.2 Plate Bubble Check
5.3 Horizontal Collimation Check
5.4 Vertical Collimation Check
5.5 Trunion Axis Check
5.6 Optical Plummet Check
5.7 Diaphragm Orientation Check
5.8 Set/ Check the Prism Constant

6.0 Total Station  - Control and Setting Out
6.1 Establish accurate, reliable co- ordinated horizontal control points (Primary control), by carrying out a traverse including correct booking, checking and adjustment calculations of field data
6.2 Use primary control points to establish secondary control points
6.3 Extract setting out information from construction drawings, process and use this information to set out points on a steel framed building.

7.0 Total Station – Functions
7.1 Use the Free- Station/ Resection function to determine the position of the instrument.
7.2 Use the Check- Tie/ Missing Line function to check the distance between points which have been set out in a previous exercise.
7.3 Use the Stake- Out/ Layout function to set out points on a building.
7.4 Capabilities and limitation of the Total Station

8.0 Theory and Knowledge
8.1 Site Engineer’s duties/ responsibilities
8.2 Adjusting Collimation Error in a Level
8.3 Checking adjustment of a spirit Level
8.4 Adjusting the plate bubble of a target/ theodolite
8.5 Setting out position/ levels of concrete reinforcement
8.6 Appropriate care of surveying equipment
