ʻO ka paipu kila kalapona ʻo Hōʻike 80 he ʻano paipu i hōʻike ʻia e kona pā mānoanoa i hoʻohālikelike ʻia me nā papa hana ʻē aʻe, e like me ka Hōʻike 40. ʻO ka "papahana" o ka paipu e pili ana i kona mānoanoa o ka pā, e pili ana i kona helu kaomi a me ka ikaika o ke kūkulu ʻana.
ʻO nā hiʻohiʻona koʻikoʻi o ka Hōʻike 80 Pipe kila kabone
1. ʻO ka mānoanoa o ka pā: ʻoi aku ka mānoanoa ma mua o ka Hōʻike 40, e hāʻawi ana i ka ikaika a me ka lōʻihi.
2. Paʻi Paʻi: ʻOi aku ka nui o ke kaomi ma muli o ka hoʻonui ʻana i ka mānoanoa o ka pā, e kūpono ana i nā noi kiʻekiʻe.
3. Mea Hana: Hanaʻia me ke kila kalapona, e hāʻawi ana i ka ikaika maikaʻi a me ka lōʻihi, a me ke kū'ēʻana i kaʻaʻahu a me ka waimaka.
4. Nā noi:
ʻOihana Piping: Hoʻohana ʻia i nā ʻoihana e like me ka aila a me ke kinoea, ka hana kemika, a me ka hana mana.
Plumbing: He kūpono no nā laina lako wai kiʻekiʻe.
Kūkulu: Hoʻohana ʻia i nā noi hoʻolālā kahi e koi ʻia ai ka ikaika kiʻekiʻe.
