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.
