Kusiyana uku kunobvumira zvikamu zvisina maburi kusangana nehunhu hwezvinhu zvinodiwa kumapurojekiti akasiyana einjiniya. Maumbirwo ejometri ezvikamu zvisina maburi anowanzo kwezva runako kupfuura zvikamu zvakasimba, zvichiita kuti zvikodzere mapurojekiti uko dhizaini uye runako zvinofungwa nezvazvo. Nekuda kwekushandisa kwazvo zvinhu zvinobudirira, zvikamu zvisina maburi zvinogona kuderedza marara ezviwanikwa, zvichienderana netsika dzisingakuvadzi nharaunda.
Kurongedza:
1. Kurongedza kwakakosha zvikuru kunyanya kana zvinhu zvichitumirwa kunze kwenyika, zvinhu zvinopinda nenzira dzakasiyana-siyana kuti zvisvike kunzvimbo yekupedzisira, saka tinonyanya kufunga nezvekurongedza.
2. Saky Steel inorongedza zvinhu zvedu nenzira dzakasiyana-siyana zvichibva pazvigadzirwa. Tinorongedza zvigadzirwa zvedu nenzira dzakasiyana-siyana, dzakadai se,
