Q460 kila, ʻaʻole maopopo ka hapa nui o nā kānaka. ʻO ka hoʻolālā hoʻolālā "Bird's Nest" he mea kū hoʻokahi a me ka moʻolelo, a ʻo ka Q460 no ke kūkulu ʻana i kona hale kila he nui nā hiʻohiʻona kūʻokoʻa: ʻO Q460 he kila ikaika kiʻekiʻe haʻahaʻa haʻahaʻa e hoʻololi i ka plastically ke hiki ka ikaika i 460 MPa. ʻOi aku ka nui o kēia ikaika ma mua o ke kila maʻamau, no laila paʻakikī loa ka hana ʻana. ʻO kēia ka manawa mua i hoʻohana ʻia ai ke kila kikoʻī Q460 i ke kūkulu ʻana i ka ʻāina. ʻO ka mānoanoa o ka pā kila i hoʻohanaʻia i kēia manawa he 110 mm, kahi mea kūikawā i ka wā ma mua. I ka pae aupuni, ʻo ka mānoanoa nui o ka Q460 he 100 mm wale nō. Ma mua, ua lawe ʻia kēia kila mai Luxembourg, South Korea, a me Iapana. No ka hoʻolako ʻana i ka "Nā Manu" me ka "kūpono" Q460, mai Kepakemapa 2004, ua hoʻomaka nā mea noiʻi o Henan Wuyang Special Steel Factory i ka noiʻi ʻepekema no ka hapalua makahiki, a ua lanakila nā hoʻokolohua ʻekolu. I kēia lā, ua hoʻomaka ke kila Q460 no ka "Bird's Nest" i ka hana nui. I ka makahiki 2008, 400 tons o ke kila Q460 i hana ʻia i loko o ka hale me nā kuleana waiwai naʻauao e kākoʻo i ka hoʻoikaika ʻana o ka "Bird's Nest".
ʻO Q460 he kila ikaika kiʻekiʻe.
