Mpumalanga has over 600 bridges on a road network of over 13 000km. Lidwala was appointed by Mpumalanga Department Roads and Transport to establish a Road Asset Management System, which includes the BMS.
The Mpumalanga BMS implemented by Lidwala uses STRUMAN (developed by CSIR) to store and analyse inventory and condition data. By updating the condition data every 3 to 5 years, and using established deterioration models for structural elements, STRUMAN can predict the future condition of bridges. When combined with unit repair costs and budgets, STRUMAN can analyse the influence of funding on future bridge conditions. The BMS is thus an essential decision support and asset management tool for road authorities to propritise rehabilitaiton and replacement strategues leading to devendable budgets.
