Imibuzo Evame Ukubuzwa

Yiluphi uhlobo lwenkontileka okufanele ngilisebenzise kuphrojekthi yezindlu ezizimele?

Kumaphrojekthi ezindlu ezizimele, i-JBCC iyifomu ejwayelekile lenkontileka. Sebenzisa i-Principal Building Agreement (PBA) kumaphrojekthi angaphezu kuka-R500,000, noma i-Minor Works Agreement kumaphrojekthi amancane angaphansi kuka-R500,000. I-JBCC iqondakala kahle osonkontileka baseNingizimu Afrika futhi yakhelwe ngokukhethekile imisebenzi yokwakha.

Ngingasebenzisa i-JBCC kuphrojekthi yomkhakha kahulumeni?

Ngokuvamile, cha. Amaphrojekthi omkhakha kahulumeni avame ukugunyaza i-NEC (ama-parastatal nama-metro) noma i-GCC (iminyango kahulumeni). Nokho, amanye amaphrojekthi amancane kahulumeni noma amaphrojekthi anezidingo ezikhethekile angavumela i-JBCC. Hlala uhlola imibhalo yethenda — izochaza ifomu lenkontileka edingekayo.

Umehluko muni phakathi kwe-JBCC Principal Building Agreement ne-Minor Works Agreement?

I-Principal Building Agreement (PBA) iyinkontileka ephelele ye-JBCC yamaphrojekthi avamise ukuba ngaphezu kuka-R500,000. Ifaka imigomo ephelele yama-variation, izandiso zesikhathi, nokuxazululwa kwezingxabano. I-Minor Works Agreement inguqulo elula yamaphrojekthi amancane angaphansi kuka-R500,000, enezinqubo ezisheshisiwe nezidingo ezimbalwa ezisemthethweni.

Kungani ama-parastatal ethanda i-NEC kune-GCC?

Ama-parastatal afana ne-SANRAL, Eskom, ne-Transnet athanda i-NEC ngoba:

Indlela yokubambisana — Uhlelo lwe-early warning lwe-NEC lukhuthaza ukubambisana futhi lunciphise izingxabano
Ukuphathwa kobungozi okungcono — Uhlelo lwe-early warning lusiza ukukhomba nokuphatha ubungozi kusenesikhathi
Izinkokhelo ezisheshayo — Imijikelezo yokukhokha evamile ithuthukisa i-cash flow yosonkontileka
Izinga lamazwe ngamazwe — I-NEC isetshenziswa emhlabeni wonke, inikeza ukuhambisana kosonkontileka bamazwe ngamazwe
Ukuguquguquka — I-NEC inezinketho eziningi zenkontileka (lump sum, target cost, cost reimbursable) ukuze ihambisane nezinhlobo ezahlukene zamaphrojekthi

Ngingashintsha amafomu enkontileka phakathi nephrojekthi?

Cha. Uma inkontileka isisayinwe, uboshelwe kulelo fomu lenkontileka phakathi nesikhathi sephrojekthi. Ukushintsha amafomu phakathi nephrojekthi kudinga ukuqeda inkontileka ekhona nokufaka entsha, okuyinto engavamile futhi engelulekiwe. Khetha ifomu lenkontileka ngokucophelela ekuqaleni kwephrojekthi.

Ngazi kanjani ukuthi yiliphi ifomu lenkontileka okufanele ngilisebenzise?

Ifomu lenkontileka livamise ukuchazwa emibhalweni yethenda noma kwi-brief yephrojekthi. Kumaphrojekthi okwakha angasese, i-JBCC iyona ejwayelekile. Engqalasizindeni kahulumeni, hlola ukuthi ikhasimende ligunyaza i-NEC noma i-GCC. Uma ungaqiniseki, cela iseluleko kummeli womthetho wokwakha noma ku-quantity surveyor onolwazi ngama-contract form aseNingizimu Afrika.

Kwenzekani uma ngisebenzisa ifomu lenkontileka elingafanele?

Ukusebenzisa ifomu lenkontileka elingafanele kungaba nemiphumela emibi:

Ukudonswa ngaphandle kwethenda — Amathenda kahulumeni avame ukudonsa amabhidi angasebenzisi ifomu elichaziwe lenkontileka
Ukubambezeleka kokukhokha — Ifomu elingafanele lingadala ukudideka nokubambezeleka kokukhokha
Ubungozi bezingxabano — Amafomu ezinkontileka ahlukanisa ubungozi ngokwehlukile — ukusebenzisa elingafanele kungakushiya uvulekile
Izinkinga zokulandela imithetho — Amaphrojekthi athile adinga amafomu athile ngokomthetho (isb., amaphrojekthi e-CIDB)

Hlala usebenzisa ifomu lenkontileka elichazwe emibhalweni yethenda noma esivumelwaneni sephrojekthi.

Ingabe i-Wakha isekela zonke izinhlobo ezinkulu zezinkontileka?

Yebo. I-Wakha isekela ukukhiqizwa kwezitifiketi zokukhokha ze-JBCC, NEC, GCC ne-FIDIC, ukuphathwa kwama-variation, nokuphathwa kwezinkontileka. Ungasebenzisa amaphrojekthi ngaphansi kwamafomu ahlukene enkontileka ohlelweni olulodwa, nge-workflow eqondene nenkontileka kanye namafomethi ezitifiketi ohlobo ngalunye.

Uyini umehluko phakathi kwama-nominated nama-domestic subcontractor?

Ama-nominated subcontractor akhethwa ikhasimende noma i-principal agent, kanti usonkontileka omkhulu uphatha umsebenzi wawo kodwa unokulawula okuncane ekukhetheni. Ama-domestic subcontractor akhethwa usonkontileka omkhulu, kanti usonkontileka omkhulu unokulawula nesibopho esigcwele. Lolu hlobo luthinta ukuhamba kwezinkokhelo, isibopho, kanye nemisebenzi yokuphatha.

Isiphetho

Ukukhetha uhlobo olufanele lwenkontileka yokwakha eNingizimu Afrika — JBCC, NEC, GCC noma FIDIC — kubalulekile ekulandeleni ithenda, ekugelezeni kwezimali, nasekwabiweni kobungozi. I-JBCC ibusa ukwakha kwangasese; i-NEC ne-GCC zibusa umsebenzi womkhakha kahulumeni; i-FIDIC isebenza emaphrojekthini wamazwe ngamazwe. Ukuqonda ukuthi ngayinye iphatha kanjani izitifiketi zokukhokha, ama-variation, nokuxazululwa kwezingxabano kukusiza ukhethe ifomu elifanele futhi uliphathe ngendlela efanele.

Ukuze uphathe izinhlobo zezinkontileka zokwakha eNingizimu Afrika — izitifiketi zokukhokha ze-JBCC, NEC, GCC ne-FIDIC, i-retention ne-cash flow — endaweni eyodwa eyakhelwe ukulandela imithetho yendawo nokuletha amaphrojekthi, bheka Wakha.
