Ngā here takirua (ngā here koki matau)kua noho hei wāhanga matua o ngā whirihoranga tūāpapa matatini nā te mea he kaha ki te hono atu ki ngā taha maha. Ko tewhakapiri takirua houe tutuki ana i ngā paerewa EN74 Akomanga B me BS1139, e whakamahi ana i te hoahoa urutau paipa paerewa 48.3mm, ka taea te whakatutuki i te hononga poutū 90° i waenga i te pae whakapae me te pou poutū, ā, ka taea te whakarite i tetahi koki. He auahapūmau takiruaMā te hangarau hanga tino tika ka whakahaere te hanganga i te hapa i roto i te 0.2mm, ā, mā te āwhina o ngā raraunga i mua i te huihuinga BIM, ka whakapai ake i te tika o te hononga o ngā wāhanga i roto i te hanganga kua oti te hanga mā te 60%.

I roto i tētahi kaupapa pāka ahumahi matū i te Tonga-mā-rāwhiti o Āhia, ko tewhakapiri takiruai whakaatu i te kaha o te urutau ki te taiao: i noho tonu tōna pakari pānga ki runga ake i te 80J i te -40 ℃, he nui ake i te toharite ahumahi o te 30J mō ngā wāhanga tuku iho; kua rua te pai o te tāutanga nā te hoahoa urutau o ngā taputapu tāutanga miihini, ā, ka taea e te tīma o te 10 tāngata te whakaoti i te 300 huinga hanganga tūāpapa i roto i te rā kotahi. Mā te tukanga maimoatanga mata whakarewa wera-tuku ka roa ake te ora ratonga neke atu i te 10 tau i roto i ngā taiao pāmahana teitei me te haumākū teitei, he 60% te roa atu i ngā whakapiri noa.
