This research has constructed a risk assessment model which is used for camp facilities in high-altitude and alpine regions. This work carries out three stages: index starting establishment, choice checking, and modification to confirm the last risk evaluation indexes for the construction organization. After that, through utilizing the AHP (Analytic Hierarchy Process) method, a judgment matrix is established through pairwise comparison of indicators on all levels. This matrix may assist the work of confirming the weight values of the evaluation indicators. Next, we utilize the fuzzy quantification method to carry out the fuzzy overall evaluation on the risk that relates to the agent construction unit for barracks installations in high-altitude and frigid mountain zones.One risk evaluation framework was by us developed for building construction units of barracks in high-altitude cold regions. This framework is constituted of five first-order metrics and thirteen second-order metrics. Inside one specific case study, we used the Analytical Hierarchy Process (AHP) to carry out the calculation of the weights. The average value weights got by arithmetic method of natural risks, economic risks, environmental risks, management risks, and security risks are therefore determined as 0.085, 0.165, 0.276, 0.429, and 0.045 each one respectively. In addition, the comprehensive weight values of the second-level indicators have been discovered to lie in the scope of 0.023 to 0.175.The fuzzy rating of the risk of the substitute unit shows that the scores of the risk factors are mostly concentrated between 2 and 4, which are in the category of general risk and greater risk.
