Umgangatho wophuhliso uya kuchaphazela ukusetyenziswa kwesakhiwo.

I-scaffings ngumlinganiso obalulekileyo kwimisebenzi ephezulu yokusebenza. Yinto ebonakalayo. Ayizikhuseli kuphela ukhuseleko kuphela ngexesha lenkqubo yokuqalisa, kodwa nomgangatho wophuhliso uya kuchaphazela ukusetyenziswa kwesakhiwo. Indinyana ekhuselekileyo ayinakutyeshelwa.

Okwesibini, ibha enkulu
1) Ibha enkulu yokuwela isetwe phantsi kwebha yebha ye-cross, kwaye ifakwe kwi-angle ye-angle ye-angle ngaphakathi kwiposti.
2) Iibhlukhwe ezinkulu ezinqamlezileyo ziqhagamshelwe ngabantu be-butt. Amalungu e-butt agculelwe. Ababekwanga kwisithuba esifanayo, kwaye umgama othe tyaba phakathi kweendawo ezikufuphi awungaphantsi kwe-500mm. Kulumkele ukusetwa embindini webhani yexesha elide.
I-3) Ibar enkulu enqamlezileyo kufuneka icwangciswe kwicala elingaphakathi phakathi kwemivalo ethe nkqo kunye nefreyimu yokuhamba ngokuvakalayo kufuneka ibotshwe. Ubude bomnqamlezo omkhulu webhanile kufuneka ibe yi-4.5m kunye ne-6m.
4) Ukuphambuka ngokuthe tye kweendawo ezinkulu ezinqamlezileyo kumqolo ofanayo akuyi kuba nkulu kune-1/300, kunye nomahluko othe nkqo kumacala amane eendawo ezinqamlezileyo aziyi kudlula i-50mm. Iipakethi ezintathu ezinkulu ezinqamlezileyo ziyafuneka njengamagqabantshintshi akhuselayo kwi-subserm yendawo yokuhlala, eyi-1500mm, i-1000mm, kunye ne-500mm ephezulu kune-scalfolds, kwaye iinyawo zenyawo zimiselwe kwi-screen suble.
