bearing capacity before construction of Footings. Blinding concrete to be used where necessary, typically not shown on drawings. Foundations are assumed to have a minimum safe bearing capacity of 100kPa unless noted otherwise. This may be deemed satisfied by compliance with NZS 3604 section 3 (ultimate bearing strength of 300kPa). If foundation material is less than 100kPa safe bearing, the Design Engineer is to be contacted for alternative design.

3. The foundation encasement concrete shall have aminimum 28 days compressive strength of 20 MPa.

4. The timber rails shall be rough sawn timber to theminimum thickness and grade as specified. The timberrails should be continuous over three spans and thejoints should be staggered. The rail thickness shouldnot be made up from thinner rails.

5. The timber rails shall be tanalised to a minimum timberpreservation treatment of H4 or approved equivalent.

6. The retaining wall has been designed to supportvertical cuts in original firm clay subgrades only. Anyvariation to this design assumption should be referredto the Engineer.

7. The timber pole retaining wall shall be constructed inaccordance with the construction specification includedwith these specific design details.

8. The wall shall be constructed with a 1 in 20 verticallayback.

9. When a permanent hand-stand surface, driveway and/orthe like is constructed to the top of the retaining wall,it is recommended that the hard-stand surface is bothreinforced and secured with galvanised steel tiesthrough the top of each pole. Refer to the engineerfor specific construction details and recommendations.

10. Storm water and ground water should be divertedaway from the wall so that ponding does not occur.
