1.1 本规程涵盖了在建筑项目设计阶段提供成本分析的安排方法。 1.2 这种做法的使用提高了设计专业人员、业主和提供成本咨询服务的成本专业人员之间的沟通水平。 1.3 该实践建立了一种结构化的方法来支持设计决策。 1.4 该实践为设计和成本专业人员提供了一个框架，用于对未来相关项目使用的历史信息进行制表。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 5.1 这种做法提高了沟通水平，为项目设计过程中的成本控制提供了一种有组织的方法，还提供了识别特殊成本项目和估计之间假设变化的方法。 5.2 这种做法的使用者包括业主、开发商、承包商、成本专业人员、估算员、建筑师、工程师、规范编写者、工料测量师，以及负责在指定项目预算内成功管理建筑设计及其相关现场工作的任何人。 5.3 在以下情况下使用此报告格式: 5.3.1 承包设计成本分析服务， 5.3.2 将当前设计成本与之前的估计进行比较，以及 5.3.3 响应每个设计阶段。 5.4 这种做法为分析设计方案和检查维护项目预算的策略提供了一种工具。

1.1 This practice covers an arranged method for providing cost analysis during the design phase of a building project. 1.2 The use of this practice increases the level of communication between the design professional, owner, and the cost professional providing the cost consulting services. 1.3 The practice establishes a structured method to support design decisions. 1.4 The practice provides design and cost professionals with a framework for historically tabulating information to be used on relevant future projects. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 This practice increases the level of communication, provides an organized approach to cost control during the design of a project, and also provides a means of identifying extraordinary cost items and changes in assumptions between estimates. 5.2 The users of this practice include owners, developers, contractors, cost professionals, estimators, architects, engineers, specification writers, quantity surveyors, and anyone charged with the responsibility of successfully managing the design of a building and its related site work within a specified project budget. 5.3 Use this reporting format during the following: 5.3.1 Contracting for design cost analysis services, 5.3.2 Comparing the current design costs to a previous estimate, and 5.3.3 Responding to each design phase. 5.4 This practice provides a tool for analyzing design options and examining strategies to maintain the project budget.
