Cofa iqhosha elisekunene
1. Iziseko zoDonga oluseMgangathweni:Iziseko ezinzulu zezakhiwo eziphakamileyo, iifektri, iindawo zokugcina impahla, izakhiwo zorhwebo nezindlu zokuhlala. Iziseko eziziimfumba (zifanelekile kuzo zonke iintlobo zezakhiwo).
2. Iziseko zeBridge Pile:Iziseko ezithwala imithwalo zeebhulorho zeendlela ezinkulu, iibhulorho zikaloliwe, kunye nee-viaducts zasezidolophini. Iziseko zemfumba yeebhulorho zomlambo, ichibi, kunye neebhulorho ezinqumla ulwandle.
3. Ukwakhiwa kweZibuko:Iziseko ezithwala imithwalo zezikhululo zezibuko, iindawo zokubeka iinqanawa, kunye namaqonga eenqanawa. Izixhobo ezinzima kunye nezixhobo zokuphatha imithwalo yezibuko.
4. Iiprojekthi zoBunjineli boMbane woMoya oLwandle kunye nooLwandle:Iziseko zeeturbine zomoya zasemaphandleni. Uyilo lwenkxaso yamaqonga aphesheya kolwandle, imibhobho yasemaphandleni, iindonga zamanzi, njl. Ukumelana namaza, ukumelana namaza, kunye nokumelana nokugqwala kolwandle.
5. Ubunjineli Bokwakha Obukhulu:Iziseko ezinzulu ezineenqwaba ezinkulu zeeprojekthi zobunjineli bokwakha ezinkulu (ezifana namadama, izitishi ezingaphantsi komhlaba, kunye neetonela). Inkxaso yoomatshini bemizi-mveliso kunye nemithwalo yezakhiwo.
1) IOfisi yeSebe - inkxaso yabantu abathetha iSpanish, uncedo lokucoca impahla, njl.njl.
2) Ngaphezulu kweetoni ezingama-5,000 zesitokhwe esikhoyo, kunye nobukhulu obahlukeneyo
3) Ihlolwe yimibutho enegunya efana neCCIC, SGS, BV, kunye neTUV, kunye neepakethe ezisemgangathweni ezifanelekileyo elwandle
Ukupakisha oku-1:Ibhandeji yentsimbi ukuze kube lula ukuyiphatha. Iibhloko zomthi okanye i-dunnage zifakwa phakathi kweenqwaba ukuze kuthintelwe ukutshintsha kwezitho ngexesha lokuthuthwa. Unyango lomphezulu (ukhetho): Ukupenda okumnyama, ioyile yokuthintela umhlwa, ifilimu yeplastiki. Iinqwaba ze-galvanized ezitshixwayo ezishushu zinokugqunywa ngefilimu yokukhusela yexeshana ukuze kuthintelwe ukukrweleka kumphezulu. Iipakethe ezenziwe ngokwezifiso zinokubonelelwa.
2 Ukuhanjiswa:Ubude bempahla eqhelekileyo: 6m, 12m. Ifumaneka ngobude obuqhelekileyo. Iza neSea Rail kunye neNdlela Efanelekileyo. Ifanelekile ukuthutha ngolwandle, ngololiwe okanye ngemoto. Ixesha lokuhambisa lidla ngokuba ziintsuku ezili-15-30 emva kokufumana intlawulo, kuxhomekeke kubungakanani kunye neenkcukacha. Ifanelekile ukuthunyelwa kwamanye amazwe kwihlabathi liphela, kunye noxwebhu olupheleleyo (isatifikethi sokuhlola, uluhlu lokupakisha, i-bill of lading).
Amanyathelo okuzikhusela amathathu:Musa ukusebenzisa izilingi okanye iihoko ezingenazo iipadi ukuze zisebenze ngqo kumphezulu wombhobho ukuze uphephe ukuba umbhobho ungaguquki. Gcina kwindawo epholileyo, eyomileyo nengena umoya kakuhle, kuphephe ukugqwala ngaphambi kokuba ufake. Ukuthunyelwa okugqithisileyo nobunzima obugqithisileyo nceda ulandele imigaqo yokuthunyelwa kwempahla yasekuhlaleni.
