Gukiza ibyuka ni ihuriro ryingenzi mugukora no gutunganya ibicuruzwa bya sima. Ntabwo bifitanye isano gusa nubuziranenge bwibicuruzwa, ahubwo bigira ingaruka kuburyo butaziguye ku musaruro, igiciro cy’umusaruro no gukoresha ingufu za beto. Ntabwo mu gihe cy'imbeho ikonje gusa, beto igomba gushyuha kenshi, ariko mugihe cyizuba gishyushye, kugirango wirinde ibice biterwa nubushyuhe bukabije hagati yimbere ninyuma cyangwa ubushyuhe burigihe, beto ikenera gukira. Gukiza ibyuka bya sima bifatanije na beto yo gukiza ibyuma bitanga ingufu nuburyo bukenewe. Kuva kubaka ibiti byumurima kugeza kumashanyarazi, gusuka ibiti, gukiza ibyuka nibindi byiciro, umusaruro wa beto ya precast ugomba kuba ufite ibisabwa byimikorere nibisobanuro, cyane cyane mugihe cyo gukira. Kugirango hamenyekane niba inyubako zubatswe zihamye kandi zirambye, ni ngombwa cyane cyane kubungabunga ibice bifatika ushimangira gukoresha ibyuma bitanga amashanyarazi. Gukoresha beto ikiza yamashanyarazi irashobora gutanga ubushyuhe bukwiye nubushuhe bukwiye bwo gukomera, kwihutisha ibikorwa byubwubatsi, no kurinda umutekano nubwiza bwibiti byateguwe. Ikintu cyingenzi cyane nuko generator yamashanyarazi kugirango ibungabungwe neza irashobora guhuzwa nuburyo bwaho ukurikije ibikoresho, inzira, nibikoresho. Hashingiwe ku kwemeza imbaraga zo kurekura, gabanya ihindagurika risigaye kandi ugabanye ukwezi gukira, aribwo ngengabitekerezo iyobora yo gushyiraho uburyo bwo gukiza.
Imashini itanga ingufu za Nobeth ifite umusaruro wihuse, ubwinshi bwamazi, gutandukanya amazi n amashanyarazi, imikorere yumutekano muke, hamwe nigikorwa cya buto imwe, cyoroshye kandi cyihuse, kandi kizamura imikorere yumusaruro no kubungabunga.
