Instruction Example 8.1.: Sawn Timber Storage Yard

This example serves to practise the preparation of a storage yard for sawn timber for natural open-air drying of the piled up wood.

Material

Figure

Pile stones of concrete or natural stone
Dimensions:
Width: at	least 400 mm
Length: at	least 400 mm
Height: at	least 300 mm
Squared timbers (impregnated with preservatives)
Dimensions:
Width: at	least 100 mm
Length: at	least 1000 mm
Thickness: at	least 100 mm

Tools

If necessary, earthwork too Is like pick, shovel, spade, hoe

Measuring and testing means

Measuring tape, folding or solid rule, long straightedge, water level, stretching line

Necessary previous knowledge

Types of wood, properties of wood, measuring, testing

Sequence of operations	Comments
1. Decide on the location of the sawn timber storage yard.	Take into account the necessary distances to neighbouring premises and the main wind direction.
2. If necessary, clean the yard to remove dirt, wood and bark waste.
3. Plane the yard (if necessary).
4. Lay out the pile stones on the yard with equal length and width distances.	Make sure that the centre-to-centre distance are correct with respect to the dimensions and type (different weights) of the wood to be stored.
5. Check the position of the pile stones for horizontal position and alignment in height as well as straightness in length and width by means of long straightedge or stretching line and water level.	Put the straightedge on the pile stones in longitudinal and transverse directions and compare or tightly stretch the line over the pile stones and compare. Put water level on the straightedge or hold it at the line.
6. If necessary, change the position of the pile stones until the required position as per 5. above is achieved.	Adjust the height alignment of the pile stones by adding or removing soil on the yard.
7. Put the squared timbers on the aligned pile stones in a straight line and in parallel with each other.	The longitudinal grain direction to be in main wind direction.
8. Check the position of the squared timbers as per steps 5. and 6. above.	Similarly take into account the comments on steps 5. and 6. above.
