With the rapid development of market economy, the development of Chinese construction engineering enterprises is becoming more and more fast, its economic management is becoming more and more sophisticated. Although our country’s engineering cost consultation units set up late, but under the support of governments and related departments have been developing rapidly. In the stage of the high speed development, however, due to the excessive emphasis on macro aspect work control, lack of attention to fine work, lead to some problems in the construction phase of the project, for example, not according to the phenomenon such as the construction according to the terms of the contract.And project construction stage in the whole project construction belongs to a very important link, the construction enterprise through the study of the management of construction stage could effectively control construction costs for the enterprise to save money, improve the efficiency of the use of funds, thus reducing the project cost.Based on the engineering project construction stage as the key point, through the establishment of the project cost tracking audit system, improve the engineering construction project funds utilization rate, and can improve the risk prevention consciousness, and reduce the risk of loss, in the end to keep the project cost within a reasonable range.This article is in the collection of domestic and international engineering project construction phase cost tracking based on the study of the audit, to formulate the reasonable and scientific, tracking audit staffing and cost tracking audit plans and measures, and through the analytic hierarchy process (AHP) to track audit cost of risk control are studied.Second, from a project construction phase of the cost of tracking implementation status and risk control optimization strategy of the audit work, this is the practice of theory with practice.Project construction stage engineering cost based on analytic hierarchy process (AHP) to track audit risk control, through the establishment of cost tracking the hierarchical structure of the audit risk management, to find the main factors of risk, improve risk control management means, perfect risk management system, to reduce the cost of construction stage of uncertain factors in the process oftracking audit purposes. This article for the improvement of the project construction phase of the cost of the tracking audit risk control work has very important practical significance. |
