Ke kaʻina hana o ke kūlana o wahoKe kila ʻano Hʻo ka maʻamau e komo pū me kēia mau ʻanuʻu nui:
Ka Hoʻomākaukau ʻana i nā Mea Maka: ʻO ka mea maka no ka hana ʻana i ka H-beam he mau bila kila maʻamau. Pono kēia mau bila e hoʻomaʻemaʻe a hoʻomehana ʻia e hoʻomākaukau no ka hana ʻana a me ke kūkulu ʻana ma hope.
ʻŌwili Wela: Hoʻokomo ʻia nā bila i hoʻomehana mua ʻia i loko o kahi wili ʻōwili wela. I loko o ka wili ʻōwili wela, ua ʻōwili ʻia lākou ma o nā wili he nui a hana mālie ʻia i ke ʻano ʻāpana kea o ka beam H.
Hana Anu (Koho): Nā Pōmaikaʻi: No ka hoʻomaikaʻi ʻana i ka pololei a me ka maikaʻi o ka ʻili o nā kukuna H,nā kukuna H i ʻōwili wela ʻiahiki ke hana anu ʻia, e like me ka ʻōwili anu a me ke kahakiʻi ʻana.
ʻOki a me ka hoʻopau ʻana: Ma hope o ka ʻōwili ʻana a me ka hana anu, ʻoki ʻia a hoʻopau ʻia nā kukuna H e hoʻokō i nā kikoʻī o ka mea kūʻai aku e hoʻokō i nā ana a me nā lōʻihi i makemake ʻia.
Ka Lapaʻau ʻIli: Hoʻomaʻemaʻe ʻia nā kukuna H a mālama ʻia me ka pale ʻana i ka popo e hōʻoia i ka maikaʻi o ka ʻili a me ke kūpaʻa ʻana i ka pala.
Nānā a me ka Hoʻopili ʻana: Hana ʻia nā nānā maikaʻi o nā kukuna H i hoʻopau ʻia, me nā nānā ʻana no ke ʻano, ka pololei o ke ana, a me nā waiwai mechanical. Ke kūpono, hoʻopili ʻia a hoʻouna ʻia i ka mea kūʻai.
