(1) Kutalika kwa chikwangwani chapansi sikuyenera kupitirira 35m. Kutalika kuli pakati pa 35 ndi 50m, kutsitsa miyeso kuyenera kutengedwa. Kutalika kumeneku ndi kwakukulu kuposa 50m, kutsitsa kumayenera kutengedwa ndipo dongosolo lapadera liyenera kuwonetsedwa ndi akatswiri.
(2) Maziko a scaffold adzakhala osalala, ojambulidwa, ndi konkriti wowuma. Maziko adzaumitsidwa ndi 100mmmgn c25 konkriti, ndipo maziko kapena pad azikhala pansi pamtengo. Bolo lokhazikika likhala bolodi yokhotakhota yokhala ndi ma spans ochepera 2, makulidwe osachepera 50mm, ndi m'lifupi osati ochepera 200mmm.
3 Maziko ofukula pamtunda sakhala kutalika kofanana, mtengo wozungulira pamalo okwezeka ayenera kufalikira pamalo otsika ndi ma spans awiri ndikukhazikika ndi mtengo.
(4) Njira zodzitchinjirizi ziyenera kuganiziridwa kuwunikidwa pamaziko a scaffold. Kukweza pansi pa maziko a scaffald kuyenera kukhala 50mm pamwamba kuposa kwapansi panja, ndi dzenje lokhala ndi gawo la 200mm
