Sethula izinketho zethu zenqwaba ezithengekayo: isisombululo esiphezulu sezidingo zakho zokwakha. Enkampanini yethu, siyaziqhenya ngokuhlinzeka ngekhwalithi ephezulu ye-spiral weldedukunqwabelanisa ipayipi lensimbiezakhelwe ukumelana nezindawo eziyinselele kakhulu. Kungakhathaliseki ukuthi uhileleke ekwakhiweni kwebhuloho, ukuthuthukiswa komgwaqo noma ukwakhiwa kwezakhiwo eziphakeme kakhulu, izinqwaba zethu zikunikeza isisekelo esithembekile sokuqinisekisa ukuphila isikhathi eside nokuzinza kwephrojekthi yakho.

Ekhiqizwa kusetshenziswa ubuchwepheshe bamuva, izinqwaba zamapayipi ensimbi ashiselwe ku-spiral aklanyelwe ukuhlangabezana nezidingo ezinzima zezinhlobonhlobo zezicelo. Ukwakhiwa kwazo okumazombezombe kuqinisekisa ukusebenza okusezingeni eliphezulu, okuzenza zilungele osonkontileka nabakhi abafuna ukuqina ngaphandle kokuphula ibhange. Siyaqonda ukuthi ukuphumelela kwezindleko kubaluleke kakhulu emakethe yanamuhla encintisanayo, yingakho amapayipi enqwaba esiwanikezayo eyindlela ethengekayo ngaphandle kokuyekethisa ikhwalithi.

Ukuzibophezela kwethu ekwanelisekeni kwamakhasimende kusenhliziyweni yakho konke esikwenzayo. Ngokuhamba kweminyaka, sizakhele idumela lokugxila kumakhasimende futhi sihlinzeka ngezinsiza eziphelele zokuthengisa kwangaphambili, ukuthengisa, kanye nangemuva kokuthengisa. Lokhu kuzinikela kuqinisekisa ukuthi sihlangabezana nazo zonke izidingo zamakhasimende ethu, sihlinzeka ngemikhiqizo namasevisi ahlala edumile.

Inzuzo Yomkhiqizo

1. Lezi zixazululo ezingabizi kakhulu zinganciphisa kakhulu isabelomali sephrojekthi futhi zenze ukwakhiwa okukhulu kube lula ukwenziwa. Ezinkampanini ezifuna ukukhulisa izinsiza zazo, amapayipi enqwaba athengekayo anganikeza enye indlela esebenzayo ngaphandle kokuyekethisa ubuqotho besakhiwo.

2. Abakhiqizi abaningi, okuhlanganisa nenkampani yethu, babeka phambili ukwaneliseka kwamakhasimende ngokuhlinzeka okuphelele kwangaphambi kokuthengisa, ngesikhathi sokuthengisa, namasevisi angemuva kokuthengisa ukuze baqinisekise ukuthi amakhasimende athola ukwesekwa akudingayo kuyo yonke inqubo yokuthenga.

Ukushoda komkhiqizo

1. Izinto ezisetshenziswayo ezibiza kancane zingase zingahlangabezane nezindinganiso zekhwalithi eziqinile ezidingekayo kumaphrojekthi amakhulu, okungaholela ekuhlulekeni kwesakhiwo noma ekwenyukeni kwezindleko zokulungisa esikhathini eside.

2. Ukuqina nokusebenza kwalezi zinketho ezithengekayo kungase kuhluke, okungase kube yingozi ekuphepheni nasezikhathini zephrojekthi.
