Form 1A: Statement of Professional Opinion as to Suitability of Land for Subdivision Development: Owner/Developer: Location: I, (Full name) of (Name and address of firm) hereby confirm that: I am a geo-professional as defined in clause 1.2.2 of NZS 4404:2010 and was retained by the owner / developer as the geo-professional on the above development. Site investigations have been carried out under my direction and are described in my report. I am aware of the details of the proposed scheme of subdivision and of the general nature of proposed engineering works as shown on the following drawings: (Insert reference to all drawings including dates of latest amendments) I confirm that I have considered the level of complexity, which I believe to be Level _________. I confirm that I am suitably qualified and experienced to undertake the geotechnical assessment for this level of complexity. In my professional opinion, not to be constructed as a guarantee, I certify that the proposed works give due regard to land slope and foundation stability considerations and that the land is suitable for the proposed subdivision, providing that: (Continue on additional page if required) This professional opinion is furnished to the Council and the owner/developer for their purposes alone on the express condition that it will not be relied upon by any other person and does not remove the necessity for the normal inspection of foundation conditions at the time of erection of any dwelling.
