Ngā Taipitopito
Ka taea te hanga i ā mātou paparanga konutea mai i30 karamu/m² ki te 550 karamu/m²ā, e wātea ana mete whakapūmau wera-tuku, te whakapūmau hiko, me te whakapūmau-mua. Ka tukuna ki ia puranga hepūrongo tirotiro, ā, ka hangaia te matotoru o te paninga konutea kia rite ki te kirimana me tete manawanui o ±0.01 mm.
Ka whakamahia e mātoungā pūwero tapahi taiahokia maeneene, kia tika hoki ngā taha, ā, ko ā mātou paipa hete whakarewa tuitui tikame te mata kōwiri kounga teitei. Ko ngā roa tapahi paerewa kei waenganui i te6–12 mita, me ngā kōwhiringa paerewa o Amerika20 putu me te 40 putu, ā, ka taea hoki e tātouwhakarite i ngā roapērā i te 13 mita ina tonoa.
Me teWhare putunga 50,000 m²me te kaha whakaputa o ia rā neke atu i te5,000 tāne, ka taea e mātou te whakaratongā wā tuku tere rawa atumengā utu whakataetaehei whakatutuki i ngā hiahia o tō kaupapa.
He whānuitia ngā whakamahinga o ngā paipa piauau i roto i te hanganga, i te ahumahi me ētahi atu mara. He mea nui kia tika te takai o ngā paipa piauau me te whakahaere i te wā e kawe ana kia tukuna haumaru ai ngā hua, kia kore ai e waikura, e rerekē te āhua, e kino rānei nā te āhua o te taiao i te wā e tukuna ana.
