Uma kunobunzima ekuhlelweni, ezinye izindlela ezithembekile kufanele zisetshenziselwe ukuzilungisa. Ukufakwa odongeni kufanele kufakwe kuzo zombili izinkomba kumakhona owesilisa noma wabesifazane wesakhiwo esikhulu. Amaphoyinti wokubeka izingxenye zodonga ezixhumene nazo kufanele ahlelwe ngesimo sedayimane kuqala, kepha amalungiselelo wesikwele noma amanxeba nawo angasetshenziswa.
. Izinduku zodonga ezixhumekayo ezingxenyeni ezixhunyiwe zodonga kufanele zibekwe nge-peppendicularly kuya ebusweni obukhulu besakhiwo. Lapho zingakwazi ukusethwa zibheke khona, ukuphela kwezingxenye zodonga ezixhumeke ku-scaffolding akufanele kube ngaphezulu kunesiphetho esixhumeke esakhiweni esikhulu. Izingxenye zokuxhuma odongeni kufanele zengezwe emaphethelweni okuvunyelwa okuqondile futhi okuvulelekile.
