Mirwi yesimbi yakagadzirwa neUimhando yezvigadzirwa zvezvimiro zvinowanzoshandiswa munheyo engineering, kazhinji inogadzirwa neinopisa yakakungurutswa kana kutonhora yakagadzirwa simbi pepa. Iwo anoshandiswa zvakanyanya mukuvaka, wharves, Bridges uye mamwe mabasa ehurumende kutsigira nekusimbisa ivhu, uye kuita basa mukuchera kwakadzika nheyo dzemakomba uye kuchengetedzwa kwemahombekombe erwizi. Zvakanakira zvesimbi pepa murwi zvinosanganisira kusimba kwepamusoro, kugadzikana uye kusimba, inogona kutsungirira kudzvanywa kwevhu nemvura, uye ine kuita kwakanaka kwekuvaka uye maitiro ekudzokorora. Uye zvakare, simbi pepa mirwi inogona zvakare kugadziridzwa mukureba uye chimiro zvinoenderana nezvinodiwa zveinjiniya kuti isangane nezvinodiwa zvemapurojekiti akasiyana. Kazhinji, mirwi yesimbi, sechinhu chakakosha cheinjiniya, inoita basa rakakosha mukusimbisa ivhu, kutsigira zvivakwa uye kuchengetedza zvivakwa.
