A: Yebo. Ukusebenzisa ukuxhumeka okuboshiwe kanye nezingxenye zangaphakathi ezingathwali mthwalo kuvumela ukulungiselelwa kabusha kwendawo kalula. Amalungu ensimbi akhona angaphinda aqiniswe ukuze asekele ukunwetshwa okuqondile noma ukusetshenziswa kabusha okusindayo.

Q: Imuphi umehluko ojwayelekile wemfucuza phakathi kohlaka lwensimbi nogodo lwendabuko/ukhonkolo?

A: Ukunemba okulawulwa yifekthri ekwenziweni kwensimbi kukhiqiza cishe u-2% wezibi. Izindlela zendabuko zokusika isizinda sezingodo kanye nokhonkolo zivame ukuholela ekulahlekeni okungafika ku-20%. Insimbi iphinde igaywe kabusha ngo-100%.

Q: Ngimkhetha kanjani umphakeli wesakhiwo sensimbi osebenza ngezinto eziningi ofanele wephrojekthi yezimboni?

IMP: Bheka umphakeli onesitifiketi se-AISC, amakhono athuthukile e-CNC angaphakathi kwendlu kanye ne-BIM, kanye nomlando ofakazelwe wobunjiniyela bomthwalo oguquguqukayo oklanyelwe imishini esindayo nezinkundla zezimboni.
