【摘要】：为了使有限的建设资金发挥最大效益，有效地控制建筑工程造价就非常重要，而找出控制工程造价的因素是其关键。随着已完成建筑工程的数量增加，工程数据资料也在不断增加，然而当前国内研究对工程数据的处理较为简单，没有充分利用这些数据去发现其内在规律，本论文针对我国目前工程造价管理现状，选取了有代表性的若干建筑工程在各阶段多次性计价的变化，提出研究主题，用已完成工程造价数据来计算和分析影响建筑工程造价的因素，同时提高建筑工程造价数据资料的附加值。论文中详细介绍了建筑工程的要素和工程造价的构成，以此建立能够全面、客观地反映建筑工程各部分造价的工程造价指标体系，对影响工程造价的多方面因素进行系统分析。根据实际情况通过对建筑工程施工合同实施阶段的工程造价变化进行分析，找出影响工程造价的因素。论文中依据甘肃省某高校建设项目的6个工程的现有造价资料，对其中的相关造价数据进行摘录，整理和甄别后，将不同类型的工程造价数据进行比对，分析每项工程变更引起的单方造价变化，并针对施工合同实施期间各单位工程及分部分项工程的造价变化，，应用熵-灰数学方法创建了建筑工程造价影响因素分析模型，用工程实例分析了影响工程造价的重点因素和对工程造价影响最大的单位工程和分部分项工程。通过上述分析研究，论文得出的结论是施工合同实施阶段影响建筑工程造价的主要因素是建设单位前期准备不充分引起的现场签证、设计单位设计原因引起的变更、建设单位建设要求发生变化引起的设计变更和新增工程引起的造价变化，其次是外部环境发生变化时引起的签证和由于设计变更引起的工程拆除等签证。在建筑工程施工合同实施过程中，与建筑工程造价联系最大的分部分项工程是土建工程中的钢筋工程、混凝土工程、屋面工程和土石方工程。上述分部分项工程的造价变化对工程造价影响最大，因此在工程造价控制中应重点关注。本论文将对建筑工程实例进行定性与定量综合分析，深入剖析建筑工程施工合同实施阶段工程造价变化情况，针对分析结果总结并提出相应对策及建议，使工程造价控制更加科学化、有针对性，从而达到提高经济效益及管理水平的目的，为以后分析建筑工程造价的控制提供参考依据。
[Abstract]:In order to maximize the benefit of the limited construction funds, it is very important to control the construction cost effectively, and the key is to find out the factors that control the construction cost. With the increase of the number of completed construction projects. Engineering data is also increasing, but the current domestic research on engineering data processing is relatively simple, not fully use these data to find its inherent law. In view of the current situation of project cost management in China, this paper selects several representative construction projects in the various stages of the change of valuation, and puts forward the research topic. The factors affecting the construction cost are calculated and analyzed by using the completed project cost data, and the additional value of the construction engineering cost data is improved at the same time. This paper introduces in detail the elements of the construction project and the composition of the project cost, so as to establish an index system of engineering cost that can reflect the cost of each part of the construction project comprehensively and objectively. This paper systematically analyzes the various factors that affect the construction cost. According to the actual situation, it analyzes the change of the construction cost during the implementation stage of the construction contract. Find out the factors that affect the project cost. According to the existing cost data of 6 projects of a university construction project in Gansu Province, extract the relevant cost data, sort out and identify. This paper compares different types of engineering cost data, analyzes the unilateral cost changes caused by each project change, and aims at the cost changes of each unit project and sub-project during the implementation of the construction contract. An analysis model of influencing factors of construction cost is established by using entropy grey mathematics method. The key factors affecting construction cost and the unit engineering and sub-project which have the greatest influence on construction cost are analyzed with engineering examples. Through the above analysis and research, the paper draws the conclusion that the main factor that affects the construction project cost during the construction contract implementation stage is the on-site visa caused by the insufficient preparation of the construction unit. The changes caused by the design reasons of the design units, the design changes caused by the changes in the construction requirements of the construction units and the cost changes caused by the new projects. The second is the visa caused by the change of the external environment and the demolition of the project caused by the change of design, etc. In the process of implementation of the construction contract of the construction project. The most important sub-projects which are related to the construction cost are reinforcement engineering, concrete engineering, roof engineering and earthwork engineering in civil engineering. The cost changes of these sub-projects have the greatest impact on the project cost. Therefore, in the project cost control should pay attention to. This paper will carry on the qualitative and the quantitative comprehensive analysis to the construction engineering example, deeply analyzes the construction project construction contract implementation stage engineering cost change situation, according to the analysis result summarizes and puts forward the corresponding countermeasure and the suggestion. In order to improve the economic benefit and management level, the project cost control is more scientific and targeted, and the reference basis is provided for the analysis of the construction cost control in the future.
