Ua kūkulu ʻia ʻo Lock and Dam 15 i ka makahiki 1931 me nā pā lāʻau a me nā lāʻau.I loko o nā makahiki, ʻo ka hoʻomau ʻana o ka holo ʻana o ka moku i hoʻokumu ʻia i ka hemahema o ke kumu kahiko ma ka paia alakaʻi haʻahaʻa i hoʻohana ʻia e ka moku e komo a puka i waho o ke keʻena laka.
ʻO Helm Civil, he hui nui ma East Moline, Illinois, ua kau inoa i kahi aelike waiwai loa me ka Army Corps of Engineers ma ka Mokupuni ʻo Rock Island e hoʻopau i nā mokulele 12 30-kapuai.E hoʻohui a hoʻokomo i 63 mau kumu wili.
"ʻO ka ʻāpana a mākou e poni ai he 360 kapuaʻi ka lōʻihi a he 5 kapuaʻi ke kiʻekiʻe," i ʻōlelo ai ʻo Clint Zimmerman, ka luna o ka papahana kiʻekiʻe ma Helm Civil."ʻO kēia mau mea āpau ma kahi o 7 a 8 kapuaʻi ma lalo o ka wai, kahi mea e kū nei i kahi paʻakikī kūʻokoʻa."
I mea e hoʻopau ai i kēia hana, pono e loaʻa iā Zimmermann nā lako pono.ʻO ka mea mua, pono ʻo ia i kahi grinder hiki ke hana ma lalo o ka wai.ʻO ka lua, pono ʻo ia i ka ʻenehana e hiki ai i ka mea hana ke mālama pono i ka pali i ka wā e wili ai i lalo o ka wai.Ua noi ʻo ia i ke kōkua ʻana i nā mīkini alanui a me ka hui lako.
ʻO ka hopena ka hoʻohana ʻana o Komatsu Intelligent Machine Control (iMC) PC490LCi-11 excavators a me Antraquiq AQ-4XL grinders me ka ʻenehana GPS i hoʻohui ʻia.E ʻae kēia iā Helm Civil e hoʻohana i ke kumu hoʻohālike 3D e hoʻomalu i kona hohonu a mālama pono i ka wā e wili ai, ʻoiai inā e loli ka pae o ka muliwai.
"Ua hui pū ʻo Derek Welge lāua ʻo Bryan Stolee i kēia mau mea, a ʻo Chris Potter kekahi hana koʻikoʻi," wahi a Zimmerman.
E paʻa ana i ke kumu hoʻohālike ma ka lima, e kau pono ana i ka excavator ma ka moku ma ka muliwai, ua mākaukau ʻo Helm Civil e hoʻomaka i ka hana.Ke wili ka mīkini ma lalo o ka wai, hiki i ka mea hoʻohana ke nānā i ka pale i loko o ke kaʻa o ka excavator a ʻike pono i kona wahi a me ka mamao e pono ai ʻo ia e hele.
"ʻOkoʻa ka hohonu o ka wili ʻana me ka pae wai o ka muliwai," wahi a Zimmerman."ʻO ka maikaʻi o kēia ʻenehana ʻo ia ka hiki iā mākou ke hoʻomaopopo mau i kahi e wili ai me ka nānā ʻole i ka pae wai.Loaʻa i ka mea hoʻohana ke kūlana hana pololei.He mea kupanaha loa keia.

ʻO ka hoʻohana ʻana i ka mana mīkini akamai a Komatsu i hiki ai iā Helm Civil ke hoʻopau i ka papahana ma kahi kokoke i ka hapalua o ka manawa i manaʻo ʻia.
"ʻO ka hoʻolālā wili no ʻelua pule," i hoʻomanaʻo ai ʻo Zimmerman."Ua lawe mai mākou i ka PC490 i ka Pōʻalima, a laila hoʻokomo mākou i ka grinder ma ka Pōʻalima a paʻi kiʻi i nā wahi mana a puni ka kahua hana.Ua hoʻomaka mākou e wili i ka Pōʻakahi a ua hana mākou i 60 kapuaʻi i ka Pōʻalua wale nō, he mea kupanaha loa.Ua hoʻopau mākou i kēlā Pōʻalima.ʻO kēia wale nō ke ala i waho.CEG
