After the entry of WTO, construction enterprises acutely need to improve the technology level through R&D activities for the market competitive ability. With the perfection of the mode of technology innovation dynamic mechanism and policy in Chinese construction industry, its enterprises will add the input of R&D extremely. Because of the uncertainties of R&D activity in construction enterprises, especially the character of easy-used of construction technology and the fluidity of construction professional, the investment of R&D is extremely likely to fail. So, the construction enterprises need to forewarn the risk of R&D investment projects. This paper prescribes the risk measurement of R&D investment projects in construction enterprises and builds the forewarning limitation based on the principle of system dependence and Shewhart control charts to warn the fluctuation of risk values of R&D investment projects in construction enterprises early. Then the mental trend of decision-makers in construction enterprises is correctly judged by the method of time series regression. In the last, the validity of the model is proved by a case.
