Ko tēnei momokotahi te whakapirikua arotauhia mō ngā āhuatanga hanga whare teitei rawa, me te hanganga marara ahotea huri noa i ngā kōhao pūtu, ka whakaiti i te tauwehenga kukū mā te 65%. Ka taea e te kaha pikau kawenga pūwāhi kotahi te eke ki te 25 tāne, he 67% teitei ake i ngā wāhanga tuku iho. I muri i te maimoatanga whakawera wera i runga i te mata, ka piki ake te ātete waikura rehu tote mā te 5 ngā wā. I roto i ngā taiao uaua pērā i ngā piriti takutai me ngā taiwhanga paipa o raro whenua, he iti iho i te 0.1% te tere waikura i muri i ngā rā 300. Ko te whakamātautau tuturu o tētahi kaupapa teitei rawa e whakaatu ana ko te nekehanga pūnga o te tūāpapa e whakamahi ana i tēnei whakapiri he 1/5 noa iho o te uara hoahoa i roto i tētahi whakamātautau whakaata awhiowhio 14 taumata, ka waiho hei "pūnga haumaru" pono.

I te mea ko tewāhanga hononga matuao tepūnaha tūāpapa, ko te kaha hanganga o tētahi whakapiri kotahi te mea e whakatau tika ana i te haumaru o te hanga. Ko te whakapiri kotahi whakauru hou kua hangaia mā te hangarau whakapiri toru-ahu, e whakanui ana i te kaha kume o ngā whakarewa tuku iho mai i te 600MPa ki te 850MPa, he pikinga 40%. Ko te putanga matua kei roto i te whakamahinga o te hangarau whakapiri isothermal me te maimoatanga wera para, e whakaoti ana i te raruraru ahumahi o "kāore e taea te whakatutuki i te kaha me te pakari i te wā kotahi" - me te pupuri tonu i te kaha teitei, ka piki ake te tere whakaroa ki te 18%, he 2.2 ngā wā i te tuku iho.ngā hua.
