Abstract There are rare hazard evaluation methods aiming at the construction hazard of parallel construction in multi-project. In
this paperconsidering the characteristics of multi-projecta fuzzy Markov model based on reliability analysis was established with
the help of fuzzy theorymarkov theory and reliability theory. The model provides a theory basis for the hazard control of the project.
It will also avoid aimless hazard control of the projectwhich plays a part in costs saving. This model was used in the hazard
evaluation of the construction process of a residential building. Results show that the strength of the protecting wall of the foundation
pits of project 1 and project 4 are not enough in next periodmaking the hazard probability pretty high. Their foundation pits should
be reinforced. Moreoverhazard levels of the project 2 and project 3 are under controlwhich keep consistent with the feedback
during construction.
