| With the construction industry, the project’s complexity and technical requirements increases. However, due to the changing construction environment, the construction process will inevitably be some disruption events, resulting in the construction efficiency losses, caused an increase in the duration and cost, the formation of the project claim. And in the event of loss of efficiency of the construction, the identification of the causes and measurement accuracy has become the focus of debate both sides. If the parties can not reach an agreement, can easily lead to disputes, resulting in extension of time, engineering costs, and even affect the quality of the project, resulting in the project can not be carried out smoothly, has brought huge losses to both sides. So fair and reasonable deal with claims for loss of construction efficiency, standardize their causes identified methods and measurement methods for rational allocation of responsibility on contract parties explicitly provide the basis for such compensation. However, claims for loss of efficiency in the construction of a lack of systematic in-depth study, mainly because there are no loss of efficiency of the construction given enough attention to this issue."Standard construction tender documents" and "construction contract model text", there are questions regarding the relevant provisions of the claim, but did not explicitly claim for loss of construction efficiency approach on the issue, even if you can apply the relevant processes, but also the lack of specific and feasible compensation method. Can not fully and efficiently handle both sides guidance on contract construction efficiency loss claims, it is difficult to adapt to the actual project. Therefore, it is necessary to strengthen the construction project efficiency loss claims issues.This paper analyzes the efficiency of construction damage claims related issues research status, loss of efficiency in the construction of the theoretical basis, the loss of efficiency of the construction of the meaning and interpretation of the brief definition, research and discuss issues for the foundation. The introduction of contract theory and asymmetric information theory, through theoretical analysis, due to construction projects of special nature of the transaction, it has a high asset specificity, transaction process too much uncertainty and transaction frequency characteristics, as the transaction both bounded rationality and negligence, contract language ambiguous and other issues, leading to incomplete contracts. From reduced transaction costs for the subsequent, improved incomplete contract perspective of efficiency loss claim construction issues provide a theoretical basis. Meanwhile, China’s construction market there is information asymmetry that exists between the contractor and the owner a lot of information blind spots, so this is also from asymmetric information theory to analyze the efficiency of construction problems of damage claims in the construction process to disclose information, the important role of reducing information asymmetry. Subsequently elaborated construction efficiency loss claims problems, according to the actual situation, put forward China’s current construction efficiency losses, lack of awareness of the efficiency of construction damage claims is weak, inadequate management of time and evidence, claims mechanism is not perfect and other issues. Among them, the loss of efficiency for the construction and construction is difficult to identify causes of loss of efficiency is difficult to precisely quantify the value of these two difficulties, using a combination of qualitative and quantitative research methods. First, the genetic relationship between cause and effect matrix diagram and two tools, identify the causes of loss of efficiency of construction, the construction efficiency loss event for qualitative analysis. Then, using the learning-forgetting curve method, Measured Mile method and K-means clustering analysis, the value of the construction efficiency losses and precise quantitative analysis quantified. Through analysis, we can effectively help the two sides to determine the construction on contract causes loss of efficiency and clear the amount of compensation, reduce disputes the claim event occurs, to some extent, saving transaction costs of the project. Finally, the construction work on improving the efficiency loss claims put forward relevant proposals.In this paper, a combination of qualitative and quantitative methods, application contract theory and asymmetric information theory, draws extensively on research results at home and abroad, combined with China’s national conditions and engineering development status, to promote and improve the construction efficiency loss claims put forward reasonable suggestions for the Order of the contracting parties a fair, rational, scientific and efficient handling of claims for loss of efficiency of construction provides the basis for reducing the dispute between the parties, to ensure the project proceed smoothly. Meanwhile, regulate the construction market order also played a positive role. |
