This section discusses and analyses the MC issues classification shown in section III and the available monitoring systems for MC monitoring to design a fully automated monitoring system for MC.Based on the previous section, the available automated MC monitoring systems cover only 30% from the MC issues found. Table 2 and Figure 5 identify the automated systems used for MC issues and the percentage of these automated systems to the manual respectively.Besides that, from the survey, and by addressing and analysing the effect of each underground environmental utilities type effect on the health of the MC structure, it is found that Water/Sewer underground utilities is the most utility affect the MC structure by causing the most MC issues. Figure 6 represents the percen tages of the MC issues causes by the different type of the underground utilities based on this survey.
