These guidelines provide essential information regarding Buried corrugated metal structures (BCMS) from the design process, installation, in-service monitoring, through to maintenance and repair procedures. BCMS have been used in Australia as an attractive solution to under road drainage requirements due to the low cost and fast construction times achievable. Several incidents of significant failures of BCMS, however, have been reported in current practice. In most observed failures, corrosion has been a critical issue which resulted in subsequent maintenance, rehabilitation and replacement. In addition, thinner sections have been introduced to the Australian market and included in Australian Standards, potentially increasing future problems with premature corrosion and deterioration.
