Ndi nga shandukisa foromo ya khonṱiraka vhukati ha phurojeke?

Hai. Musi khonṱiraka yo no sainiwa, ni bohelela kha foromo yeneyo lwa tshifhinga tshoṱhe tsha phurojeke. U shandukisa maforomo vhukati ha phurojeke zwi ḓo ṱoḓa u fheliswa ha khonṱiraka ya kale na u dzhena kha ntswa, zwe kanzhi zwa sa vhi zwa vhukuma kana zwa khuthadzwa. Nangani foromo ya khonṱiraka nga vhuronwane mathomoni a phurojeke.

Ndi ḓivha hani uri ndi fanela u shumisa foromo ifhio ya khonṱiraka?

Foromo ya khonṱiraka kanzhi i bulwa kha dzidokhumente dza tender kana project brief. Kha diphurojeke dza vhukovheli ha poraivethe, JBCC ndi yone nḓowelo. Kha inifurasitirakha ya muvhuso, sedzani uri mutengi u laedza NEC kana GCC. Arali ni songo khwaṱhiswa, ambeni na muimeleli wa mulayo wa vhukovheli kana quantity surveyor ane a divha maforomo a dikhonṱiraka dza Afurika Tshipembe.

Hu bvelela mini arali nda shumisa foromo yo khakheaho ya khonṱiraka?

U shumisa foromo yo khakheaho ya khonṱiraka zwi nga vha na mvelelo khulwane:

U hanelwa kha tender — Tender dza muvhuso kanzhi dzi hanelwa zwikumbelo zwi sa shumiseng foromo ya khonṱiraka yo bulwaho
U lenga ha mbadelo — Foromo yo khakheaho i nga bveledza u sa pfesesa na u lenga ha mbadelo
Khombo ya thaidzo — Maforomo a dikhonṱiraka a kovhekanya khombo nga ndila dzo fhambanaho — u shumisa yo khakheaho zwi nga ni sia no bviselwa khagala
Thaidzo dza u tevhedza — Dziṅwe diphurojeke nga mulayo dzi ṱoḓa maforomo o khetheaho (tsumbo, diphurojeke dza CIDB)

Nayo tshifhinga shumisani foromo ya khonṱiraka yo bulwaho kha dzidokhumente dza tender kana kha thendelano ya phurojeke.
