E whakaatu ana ngā kamupene hangarau me ngā kaihanga maitai kua whānuitia te whakamahinga oarawhata maitai ritengae whakawhirinaki ana ki ngā painga matua e toru:
1. Te Pakari o te Hanganga Kāore e Taea te Whakaōrite
He rerekē ki te rakau, he ngāwari ki te piko me te pirau, ki te raima rānei, he roa te wā e pakari ai, ā, he nui te kawenga mate e uru ana ki te whare, he mīharo te ōwehenga kaha-ki-taumaha o te maitai hanganga.Ngā arawhata maitai houkua pania ki ngā maimoatanga ārai-waikura pai rawa atu - pērā i te whakawaiwai wera, i ngā pūnaha paninga paura ahurei rānei - ā, ka roa mō ngā tekau tau me te iti noa o te tiaki.
2. Teitei o te Whakaritenga me te Āhua Ataahua
Mai i ngā arawhata pōturi iti mō te tari matua o te kamupene ki ngā arawhata putanga ahumahi taumaha, he tino ngāwari te āhua o te rino. Ka taea e ngā kaihangarau te hoahoa i ngā hoahoa rere porowhita, porowhita, tika rānei, ka taea te whakauru katoa ki ngā takahanga karāhe, rakau, raima rānei kia rite ki tētahi hiahia tirohanga motuhake.
3. Tāutanga Tere me te Whai Hua o te Utu
I roto i te rāngai arumoni, ko te wā he moni. Mā te whakamahi i te pūmanawa BIM (Building Information Modeling) matatau, ka taea e ngā kaiwhakarato hanga maitai taumata teitei te hanga arawhata maitai i waho o te papaanga kia rite ki ngā whakaritenga mirimita tika.
Te Tirohanga Ahumahi: Ngā wāhanga arawhata maitai kua oti te hangaka taea te tuku tika atu ki te papa hanga, kia rite ai mō te tāutanga tonu. Mā tēnei tikanga ka whakaitihia te wā whakatū i te papaanga tae atu ki te 50% ki te whakaritea ki ngā arawhata raima tuku iho, ā, ka nui ake te penapena i te reti o te kerēni me te utu mahi.
