**5. Conclusions**

Schedule delay risk was analyzed to provide a decision regarding the typical risk of delay in construction lifecycle to mitigate risk. This was achieved through the application of the hybrid model of FCE and TOPSIS. The application of this combined model can evaluate not only the typical risk of the schedule delay but also reflects the general risk of schedule delay. Based on the empirical study, the results identified that the risk level of the schedule delay varies at the construction projects lifecycle. The comparison on the empirical study shown that the construction stage (44%) is high risk, the second high-risk stage is post construction (37%), and the least risk is pre-construction (35%). The construction projects in Ethiopian have faced an average of 38% of schedule delay risk at the high and very high-risk level. This helps the construction managers to identify which schedule delay risk factor is highly influential and which construction lifecycle is highly risky and to make the right decision on how to mitigate the risk. The application of the integrated model of FCE and TOPSIS is a viable tool in delay risk managemen<sup>t</sup> of construction project. The model can be applied at any time, with different project types by adapting the factors and evaluated weight.
