Figure A-11: In-Fill Panel Between Timber Building Supports

Because of the relatively light nature of a timber building, extra precautions must be taken concerning uplift. Care must therefore be taken to ensure that the entire structure is securely fastened to the foundations. The spaces between the supporting columns or piers should be filled in to prevent increasing the uplift forces.

Figure A-13: Timber Framing Showing Bracing

In addition to bracing corners of timber walls in both directions, diagonal braces or steel straps must be installed at the level of the top plate to provide rigidity of the corners at that level. In summary, timber buildings must be securely anchored to the ground and the building structure itself must be tied together with timber braces or metal straps.

Figure A-14: Construction Site Layout

Areas should be allocated on the cleared site for the storage of materials. Coarse and fine aggregate for the mixing of concrete and mortar should be placed in separate heaps in a location near to the concrete mixer and/or concrete mixing area.  Cements, nails and finished materials requiring protected storage should be stored in a shed which is weather tight and has a wooden floor raised not less than four inches off the ground. Reinforcement should be stacked off the ground to reduce corrosion.

The building should be properly set out. Batter boards, which are horizontal boards parallel to the sides of the building and supported by vertical boards driven into the ground, may be erected in convenient locations near the four corners of the building, and to these boards should be transferred the building lines and levels for the project.

The floor level is usually marked on the batter boards and used as a permanent reference. All wall lines and levels should refer to these boards. Periodic checks shall be made to see that these boards have not been shifted from their intended positions.

The prevention of roof leaks at parapet wall junctions requires careful attention to detail. Metal gutters and flashings (aluminum or copper) are recommended. The gutter must be adequately fixed and supported by gutter boards as necessary.

Figure A-16(b): Damp-proofing for Retaining Walls to Buildings


The damp-proofing of basement retaining walls requires the application and protection of an adequate bitumen coating on the outer face. The use of a proprietary cementitions production such ‘Vaudex’ is also an acceptable treatment. In both cases the blockwalls must be plastered before the application of the waterproofing. A 4" diameter tile drain leading to the soakaway is recommended.
