Abstract: The traditional model environmental indicator system is complex, resulting in a long evaluation time. This paper put
forward the research on risk factor modeling of environmental impact assessment in the whole process of construction project.
Firstly, the surrounding environment of the construction project was extracted, the environmental impact indicator system was
established, and the evaluation risk factor model is constructed based on the neural network structure. During the efficiency test of
the new model evaluation risk factor model, project A and project B with different degrees of environmental impact were selected
for the experiment. The experimental results show that the new model is 10.24 s faster than the traditional method in project A
and 38.87 s faster than the traditional method in project B. It can be seen that the new model can solve the problem of long
evaluation time of traditional methods.
Key words: construction project; whole process; environmental impact; risk assessment
