Tātaitai Pakitara Pupuri

Ko ngā utu pakitara pupuri oneone i Aotearoa ka tino rerekē e ai ki te rauemi me te teitei. Ko ngā pakitara pupuri oneone kamokamo rākau ka utu tika ki te $400-800 ia mita tapawha o te kanohi (i whakauruhia, tae atu ki te terenga). Ko ngā pakitara poraka raima ka haere $600-1,200/m2 i whakauruhia. Ko ngā pakitara raima mairaro (i ringihia i-roto) ka utu $800-1,500/m2. Ko ngā pakitara gabion (kete-ua ki uta) ka utu tata ki te $400-900/m2. Ko ngā pūnaha rākau hangaia (penei i a Permacrib) me ngā pūnaha poraka aahua-patene ka noho ki te $500-1,000/m2. Ka nui ake te utu mō ngā pakitara neke atu i te 1.5m ma te hiahia i ngā mahi hangarau, ngā turanga hohonu ake, me te terenga nui ake. Whakauruhia i ngana te terenga me te whakakiki i roto i to tatauranga pūtea. Puna: buildingperformance.govt.nz; BRANZ branz.nz.

I Aotearoa, ko ngā pakitara pupuri oneone iti e mau ana i raro i te 1.5 mita oneone i runga i te oneone taatai kāore anō e tata ana ki tētahi rohe ka wehea i te whakaaetanga hanga i raro i te Rarangi 1 o te Ture Hanga 2004. Heoi, ko ngā pakitara e neke atu ana i te 1.5 mita te teitei, ko ngā pakitara i runga i te oneone panoni, ko ngā pakitara e tata ana ki ngā rohe whenua, me ngā pakitara e mau ana i te oneone e tata ana ki tētahi whare, ka hiahia katoa ki tētahi whakaaetanga hanga. Ko ngā pakitara nui ake i te 1.5m te teitei me hiahia anō i te hoahoa hanganga e tētahi Kaiwhaihanga Ngaio Rehita (CPEng). Ko ngā pakitara wehea me whai tonu ki te Waehere Hanga o Aotearoa. Ka oati anō ngā pakitara e tata ana, e kei runga ana rānei i ngā rohe ki ngā herenga korero-hoa. Tirohia tonu to kāwanatanga ā-rohe, nā te mea ka rerekē ngā paepae wehea i waenga i ngā mana-whakahaere-a-rohe. Puna: Ture Hanga 2004; buildingperformance.govt.nz.

He mea nui te terenga rite i muri i tētahi pakitara pupuri oneone mō tōna pūmau hanganga. Ki te kore he terenga, ka kohikohi te wai i muri i te pakitara, ka hanga i te kaha wai-hono e ko ana i te tāke matua o te hinga pakitara pupuri oneone i Aotearoa. Ko ngā pakitara pupuri oneone katoa me whai i tētahi paparanga terenga: konganuku tere-wai (penei i te tipu AP20) i takoto tika i muri i te kanohi pakitara; he taura teketeke geotextile hei wehewehe i te konganuku mai i te oneone mau me te aukati i te neke; me tētahi paipa para paipa whakaheke i te turanga o te pakitara hei kohikohi me te tukutuku wai mai i te pakitara. Ko te para me whai i tētahi pūtanga ki te ao-marama, ki tētahi toka-whakamoea rānei. Mō ngā pakitara nui ake i te 1m te teitei, ka tohu te hoahoa hanganga i te punaha terenga i roto i ngā korero.

Hei tātai i ngā rauemi pakitara pupuri oneone, whakaarohia tuatahi te rohe kanohi o te pakitara: ko te roa whakareatia ki te teitei toharite i roto i ngā mita ka homai i te rohe kanohi i roto i ngā mita tapawha. Mō ngā pakitara poraka raima, wehea te rohe kanohi ki te rohe kanohi o tētahi poraka (mō tētahi poraka tauanga 390mm x 190mm ko taua ko te 0.074m2) hei tiki i te maha o ngā poraka, tapirihia 10% mō te para me ngā tapahanga. Mō ngā pakitara kamokamo rākau, wehea te rohe kanohi ki te rohe kanohi kamokamo. Tataihia anō: konganuku terenga (ko te tikanga 0.3-0.5m3 ia mita raina o te pakitara), taura teketeke (rohe kanohi me te 20%), paipa para paipa whakaheke (ngā mita raina e rite ana ki te roa pakitara), ngā anchor deadman, geogrid rānei mō ngā pakitara nui ake i te 1m, me ngā turanga. Mō ngā pakitara nui ake i te 1.5m, ka homai e tētahi kaiwhaihanga he whakarite katoa. Puna: buildingperformance.govt.nz; BRANZ branz.nz.
