Iyisitezi esisodwa sengosi yensimbi yokusebenzela yensimbi, futhi isetshenziswa njengendawo yokugcina igaxa .Iqedwa ngo-2017.
Isakhiwo sendawo yokugcina impahla ebandayo siklanywe ngohlaka lwensimbi ye-portal, izingxenye eziyinhloko ziyikholomu, i-beam, i-roof purlin, i-wall purlin, iphaneli yophahla, iphaneli yodonga.Ukuze kuthuthukiswe amandla esakhiwo sonke, ngokuvamile kunezakhiwo eziningi zensimbi zesibili, ezifana ne-bracing, ibha yokundiza, ibha yokubopha njalonjalo.
Kunezidingo ezikhethekile zokuvala uphahla nodonga, kufanele zihlale isikhathi eside futhi zibe nokusebenza kokushisa okuphelele okubandayo nokushisayo.
1) Economic: efakwe ngokushesha futhi ukonga izindleko zokwakha
2) Ikhwalithi enokwethenjelwa: ikhiqizwa ikakhulukazi efektri futhi ilawula ikhwalithi
3) isikhala esikhulu: ubude besikhathi esikhulu sesakhiwo sensimbi ye-prefab singafinyelela ku-80meters
4) Ukubukeka okuhle: kungasebenzisa imibala ehlukene yophahla / ishidi lodonga.
5) Impilo ende: ingasetshenziswa ngaphezu kweminyaka engama-50
