Given the low intelligent level and the low accuracy of valuation of civil architecture projects, we
put forward in the study a constructional engineering assessment method based on Artificial Intelligence which
taking advantage of data-calculation from rough set theory, genetic algorithm and neural network algorithm.
First, the rough set theory is used to reduce the discrete attributes to optimize the input variables of BP neural
network. And then use the global search feature of genetic algorithm to optimize the initial weight and the
threshold value of BP neural network. The new algorithm covers both the global random search capability of
genetic algorithm and the learning ability and robustness of neural network, thus the computational speed and
accuracy have been more significantly improved than the traditional methods. To empirically analyze a case
selected from a city in Hunan Province, the results show that the new algorithm model can rely on the
engineering features, assess the construction costs scientifically and objectively and have high practical value.
