• Cela izibonelo zezakhiwo zokubika eziyingqopha-mlando, ezicela ngokukhethekile amashejuli e-Primavera P6 namalogi okunciphisa ubungozi kumaphrojekthi wamazwe ngamazwe adlule.

• Buyekeza izindinganiso zokugunyazwa nokunikezwa kwemibhalo ukuze uqinisekise ukulethwa kwemidwebo ebanzi njengoba yakhiwe kanye namamanuwali e-O&M.

• Funa ukwahlukaniswa okucacile kwemodeli yokusekelwa kwesayithi eshumekiwe, okuhlanganisa neziqu ezithile zabaphathi be-HSE nabahloli be-QA/QC abasatshalaliswayo.

FAQ

Q: Yini efakwe ku-a Isevisi yokufaka i-Steel villa design?

IMP: Ihlanganisa ububanzi obusuka ekupheleni kuya ekupheleni: ukwakheka kwezakhiwo nesakhiwo kusetshenziswa i-BIM, ukwakhiwa okulawulwa yifekthri kohlaka lwensimbi nemvilophu, ukuphathwa kwempahla yomhlaba wonke, ukuhlanganiswa okuphelele kwendawo, kanye nokugunyazwa kokugcina kokusebenza. Lokhu kuqinisekisa uguquko olusebenzayo ukusuka kumqondo ukuya esakhiweni okuhlalwa kuso ngokugcwele.

Q: Inkontileka ye-EPC ihluke kanjani ekwakhiweni kwendabuko kwamaphrojekthi ensimbi okuhlala?

IMP: Inkontileka ye-EPC ishintsha idizayini, ukuthengwa, kanye nezingozi zokwakha ebhizinisini elilodwa. Lokhu kwenziwa ngaphansi kwesivumelwano senani elingashintshi. Iqeda izingxabano zabathengisi abaningi, ivimbele ukukhuphuka kwe-scope, futhi ivikele ukuxhaswa kwephrojekthi ngokuqinisekisa isiqiniseko sezindleko.

Q: Iliphi izinga lokwesekwa kwesayithi lesakhiwo sensimbi yaphesheya okufanele ngikulindele?

A: Kufanele ulindele ukuthunyelwa konjiniyela besizinda abashumekiwe, abaphathi be-HSE, nabahloli be-QA/QC. Bangamela abasebenzi basendaweni, baphoqelela izindinganiso zokuphepha ezingenzi lutho, futhi baqinisekise ukuthi izingxenye ezikhiqizwe efekthri zifakwa ukuze zihambisane nemibandela yobunjiniyela enembile.

Umbuzo: Ingabe a Iphrojekthi ye-turnkey yokwakha yensimbi yomndeni yenziwe ngezifiso kumakhodi wokwakha wendawo?

A: Yebo. Phakathi nesigaba sokuqala sobunjiniyela, usonkontileka we-EPC uvumelanisa ukuhlaziya kwesakhiwo, ukuhlolwa kwenhlabathi, kanye nokucaciswa kwezinto ezibonakalayo. Lokhu kuqinisekisa ukuthi isakhiwo sihlangabezana nemithetho ethile yesifunda yokuzamazama komhlaba, umoya, kanye ne-thermal ngaphambi kokuqala kokukhiqiza.

Q: Osonkontileka be-EPC basingatha kanjani ukulawulwa kwekhwalithi yensizakalo ehlanganisiwe yokwakha indawo yokuhlala yensimbi?

A: Basebenzisa indlela enezendlalelo ezimbili. Okokuqala, i-QA/QC eqinile yenzeka emthonjeni wokukhiqiza ngaphambi kokuthunyelwa, okwaziwa ngokuthi Ukuqinisekiswa Kwekhwalithi Emthonjeni. Okwesibili, izinqubo eziqinile zokuhlola indawo kanye nokuhlolwa kokugcina kokugunyazwa kwenziwa ngaphambi kokunikezelwa.
