Proper risk management is one of the key drivers of successful project delivery. This is more apparent in competitive and fast growing industries such as telecommunication. To better understand the risks faced in construction and deployment of mobile telecom sites (MTS), a research was initiated to: (a) examine risks associated with deploying MTS, and (b) understand the means to mitigate and handle them. The first point was addressed in an earlier publication whilst this paper focuses on the second. Knowledge pertinent to mitigating and handling MTS risks has been acquired via rounds of interviews and questionnaire surveys with a panel of telecom industry experts. Flow charting has been utilized to code the acquired procedural knowledge and provide basis for developing a knowledge base expert system (KBES). The rules technique was selected for knowledge representation. Automation of the KBES is also demonstrated.
