Kunezindlu ezimbili ezigcina impahla kule phrojekthi, enye ingu-4500sqm kanti enye ingu-5000sqm. Le mpahla yesakhiwo sensimbi ibhekiselwa kungxenye eyinhloko yokuthwala yakhiwe ngensimbi.Kubandakanya amakholomu ensimbi, uthango lwensimbi, isakhiwo sensimbi, i-truss yophahla lwensimbi.Ingxenye ngayinye isebenzisa ama-weld, amabhawodi noma ama-rivets ukuxhuma.
Isakhiwo sensimbi seshede, udonga nophahla kungenziwa ngeshidi noma insimbi yeshidi Elivunyiwe, kungavimbela ukugqwala nokugqwala.Ukusetshenziswa kwe-screw self-tapping kungenza uxhumano phakathi kwamapuleti eduze kakhulu, ukuvimbela ukuvuza.Ungasebenzisa futhi iphaneli eyinhlanganisela yophahla nodonga.I-sandwich yi-polystyrene, i-glass fiber, i-rock wool, i-polyurethane.Ziyakwazi ukufakwa kahle kwe-thermal, i-heat insulation, i-fire-retardant.Udonga lokugcinwa kwesakhiwo sensimbi lungasebenzisa nodonga lwezitini.Izindleko zodonga lwezitini ziphakeme kunophahla lwensimbi nodonga.
Le esendaweni engu-5000 sqm yokwakha, isebenzisa ishidi likathayela oluhlaza.
Enye ku-4500 sqm enekholomu emaphakathi ngaphakathi.
Ishabhu yesakhiwo sensimbi, indawo yokugcina impahla yensimbi ye-PEB, ishede lokugcina, indawo enkulu yezimboni, indawo yokulala, igaraji, njll.
