ForewordNational Building Information Modeling Standard™©2007 National Institute of Building Sciences. All rights reserved .ForewordThe construction industry is in the middle of a growing crisis worldwide. With 40% of the world’s raw materials being consumed by buildings, the industry is a key player in global economics and politics. And, since facilities consume 40% of the world’s energy and 65.2% of total U.S.electrical consumption, the construction industry is a key player in energy conservation, too! With facilities contributing 40% of the carbon emissions to the atmosphere and 20% of material waste to landfills, the industry is a key player in the environmental equation. Clearly, the construction industry has a responsibility to use the earth’s resources as efficiently as possible.Construction spending in the United States is estimated to be $1.288 trillion for 2008. The Construction Industry Institute estimates there is up to 57% non-value added effort or waste in our current business models. This means the industry may waste over $600 billion each year.There is an urgent need for construction industry stakeholders to maximize the portion of services that add value in end-products and to reduce waste.Another looming national crisis is the inability to provide enough qualified engineers. Someestimate the United States will be short a million engineers by the year 2020. In 2007, the United States was no longer the world’s largest consumer, a condition that will force United States industry to be more competitive in attracting talented professionals. The United States construction industry must take immediate action to become more competitive.The current approach to industry transformation is largely focused in efforts to optimize design and construction phase activities. While there is much to do in those phases, a lifecycle view is required. When sustainability is not adequately incorporated, the waste associated with current design, engineering, and construction practices grows throughout the rest of the facility’s lifecycle. Products with a short life add to performance failures, waste, recycling costs, energyconsumption, and environmental damage. Through cascading effects, these problems negatively affect the economy and national security due to dependence on foreign petroleum, a negative balance of trade, and environmental degradation. To halt current decline and reverse existing effects, the industry has a responsibility to take immediate action.While only a very small portion of facility lifecycle costs occur during design and construction, those are the phases where our decisions have the greatest impact. Most of the costs associated with a facility throughout its lifecycle accrue during a facility’s operations and sustainment. Carnegie-Mellon University research has indicated that an improvement of just 3.8% in productivity in the functions that occur in a building would totally pay for the facility’s design, construction, operations and sustainment, through increased efficiency. Therefore, as industry focuses on creating, maintaining, and operating facilities more efficiently, simultaneous action is required to ensure that people and processes supported by facilities are optimized.BIM stands for new concepts and practices that are so greatly improved by innovative information technologies and business structures that they will dramatically reduce the multiple forms of waste and inefficiency in the building industry. Whether used to refer to a product – Building Information Model (a structured dataset describing a building), an activity – Building Information Modeling (the act of creating a Building Information Model), or a system – Building Information Management (business structures of work and communication that increase quality andefficiency), BIM is a critical element in reducing industry waste, adding value to industry products, decreasing environmental damage, and increasing the functional performance of occupants.ForewordNational Building Information Modeling Standard™©2007 National Institute of Building Sciences. All rights reserved .The National Building Information Model Standard™ (NBIMS) is a key element to building industry transformation. NBIMS establishes standard definitions for building information exchanges to support critical business contexts using standard semantics and ontologies. Implemented in software, the Standard will form the basis for the accurate and efficientcommunication and commerce that are needed by the building industry and essential to industry transformations. Among other benefits, the Standard will help all participants in facilities-related processes achieve more reliable outcomes from commercial agreements.Thus, there is a critical need to increase the efficiency of the construction process. Today’s inefficiency is a primary cause of non-value added effort, such as re-typing (often with a new set of errors) information at each phase or among participants during the lifecycle of a facility or failing to provide full and accurate information from designer to constructor. With the implementation of this Standard, information interoperability and reliability will improve significantly. Standard development has already begun and implementable results will beavailable soon. BIM development, education, implementation, adoption, and understanding are intended to form a continuous process ingrained evermore into the industry. Success, in the form of a new paradigm for the building construction industry, will require that individuals andorganizations step up to contribute to and participate in creating and implementing a commonBIM standard. Each of us has a responsibility to take action now.David A.

All rights reserved .Chapter 1.1 Executive SummaryNational Building Information Modeling Standard™ Version 1 - Part 1:Overview, Principles, and MethodologiesIntroductionThe National Building Information Modeling Standard (NBIMS) Committee is a committee of the National Institute of Building Sciences (NIBS) Facility Information Council (FIC). The vision for NBIMS is “an improved planning, design, construction, operation, and maintenance process using a standardized machine-readable information model for each facility, new or old, which contains all appropriate information created or gathered about that facility in a format useable by all throughout its lifecycle.”1 The organization, philosophies, policies, plans, and working methods that comprise the NBIMS Initiative and the products of the Committee will be the National BIM Standard (NBIM Standard), which includes classifications, guides, recommended practices, and specifications.This publication is the first in a series intended to communicate all aspects of the NBIMS Committee and planned Standard, which will include principles, scope of investigation,organization, operations, development methodologies, and planned products. NBIMS V1-P1 is a guidance document that will be followed by publications containing standard specifications adopted through a consensus process .Wherever possible, international standards development processes and products, especially the NIBS consensus process, American Society for Testing and Materials (ASTM), AmericanNational Standards Institute (ANSI), and International Standards Organization (ISO) efforts will be recognized and incorporated so that NBIMS processes and products can be recognized as part of a unified international solution. Industry organizations working on open standards, such as the International Alliance for Interoperability (IAI), the Open Geospatial Consortium (OGC), and the Open Standards Consortium for Real Estate (OSCRE), have signed the NBIMS Charter inacknowledgement of the shared interests and commitment to creation and dissemination of open, integrated, and internationally recognized standards. Nomenclature specific to North American business practices will be used in the U.S. NBIMS Initiative. Consultations with organizations in other countries have indicated that the U.S.-developed NBIM Standard, once it is localized, will be useful internationally as well. Continued internationalization is considered essential to growth of the U.S. and international building construction industries.BIM Overall Scope and DescriptionBuilding Information Modeling (BIM) has become a valuable tool in some sectors of the capital facilities industry. However in current usage, BIM technologies tend to be applied within vertically integrated business functions rather than horizontally across an entire facility lifecycle. Although the term BIM is routinely used within the context of vertically integrated applications, the NBIMS Committee has chosen to continue using this familiar term while evolving the definition and usage to represent horizontally integrated building information that is gathered and applied throughout the entire facility lifecycle, preserved and interchanged efficiently using open and interoperable technology for business, functional and physical modeling, and process support and operations. 1 Charter for the National Building Information Modeling (BIM) Standard, December 15, 2005, pg.1. See /bim/pdfs/NBIMS_Charter.pdf .Section 1 – Introduction to the National BIM Standard V 1 - Part 1Chapter 1.1National Building Information Modeling Standard™©2007 National Institute of Building Sciences. All rights reserved .NBIM Standard Scope and DescriptionThe NBIMS Initiative recognizes that a BIM requires a disciplined and transparent data structure supporting all of the following.x A specific business case that includes an exchange of building information. x The users’ view of data necessary to support the business case. x The machine interpretable exchange mechanism (software) for the required information interchange and validation of results.This combination of content selected to support user needs and described to support open computer exchange form the basis of information exchanges in the NBIM Standard. All levels must be coordinated for interoperability, which is the focus of the NBIMS Initiative. Therefore, the primary drivers for defining requirements for the National BIM Standard are industry standard processes and associated information exchange requirements.In addition, even as the NBIM Standard is focused on open and interoperable informationexchanges, the NBIMS Initiative addresses all related business functioning aspects of the facility lifecycle. NBIMS is chartered as a partner and an enabler for all organizations engaged in the exchange of information throughout the facility lifecycle.Data Modeling for BuildingsKey to the success of a building information model is its ability to encapsulate, organize, and relate information for both user and machine-readable approaches. These relationships must be at the detail level, relating, for example, a door to its frame or even a nut to a bolt, whilemaintaining relationships from a detailed level to a world view. When working with as large a universe of materials as exists in the built environment, there are many traditional verticalintegration points (or stovepipes) that must be crossed and many different languages that must be understood and related. Architects, engineers, as well as the real estate appraiser or insurer must be able to speak the same language and refer to items in the same terms as the first responder in an emergency situation. Expand this to the world view where systems must be interoperable in multiple languages in order to support the multinational corporation. Over time ontologies will be the vehicles that allow cross communication to occur. In order to standardize these many options, organizations need to be represented and solicited for input. There are several, assumed to be basic, approaches in place that must come together in order to ensure that a viable and comprehensive end-product will be produced.The Role of InteroperabilitySoftware interoperability is seamless data exchange at the software level among diverseapplications, each of which may have its own internal data structure. Interoperability is achieved by mapping parts of each participating application’s internal data structure to a universal data model and vice versa. If the employed universal data model is open, any application canparticipate in the mapping process and thus become interoperable with any other application that also participated in the mapping. Interoperability eliminates the costly practice of integrating every application (and version) with every other application (and version).The NBIM Standard maintains that viable software interoperability in the capital facilities industry requires the acceptance of an open data model of facilities and an interface to that data model for each participating application. If the data model is industry-wide (i.e. represents the entire facility lifecycle), it provides the opportunity to each industry software application to become interoperable.Section 1 – Introduction to the National BIM Standard V 1 - Part 1Chapter 1.1National Building Information Modeling Standard™©2007 National Institute of Building Sciences. All rights reserved .Storing and Sharing InformationOne of the innovations, demonstrated by some full-service design and engineering firms and several International Alliance for Interoperability (IAI) demonstration projects, has been the use of a shared repository of building information data. A repository may be created by centralizing the BIM database or by defining the rules through which specific components of BIM models may be shared to create a decentralized shared model. As BIM technology and use matures, thecreation of repositories of project, organization, and/or owner BIM data will have an impact on the framework under which NBIMS operates. Owners are likely to create internally as-built and as-maintained building model repositories, which will be populated with new and updated information supplied via design/construction projects, significant renovations, and routine maintenance and operations systems.Information AssuranceThe authors caution that, while a central (physical or virtually aggregated) repository of information is good for designing, constructing, operating, and sustaining a facility, and therepository may create opportunities for improved efficiency, data aggregation may be a significant source of risk.Managing the risks of data aggregation requires advanced planning about how best to control the discovery, search, publication, and procurement of shared information about buildings and facilities. In general, this is addressed in the data processing industry through digital rights management. Digital rights management ensures that the quality of the information is protected from creation through sharing and use, that only properly authorized users are granted access, and only to that subset of information to which they should have access. There is a need toensure that the requirements for information are defined and understood before BIMs are built, so that facility information receives the same protection that is commonplace in world-wide personnel and banking systems.Minimum BIM and the Capability Maturity ModelThe NBIM Standard Version 1 - Part 1 defines a minimum standard for traditional vertical construction, such as office buildings. It is assumed that developing information exchange standards will grow from this minimum requirement.The Standard also proposes a Capability Maturity Model (CMM) for use in measuring the degree to which a building information model implements a mature BIM Standard. The CMM scores a complete range of opportunity for BIMs, extending from a point below which one could say the data set being considered is not a BIM to a fully realized open and interoperable lifecycle BIM resource.The U.S. Army Corps of Engineers BIM Roadmap 2 is presented as a useful reference for building owners seeking guidance on identifying specific data to include in a BIM from a design or construction perspective.2 See https:///default.aspx?p=s&t=19&i=1 for the complete roadmap.Section 1 – Introduction to the National BIM Standard V 1 - Part 1Chapter 1.1National Building Information Modeling Standard™©2007 National Institute of Building Sciences. All rights reserved .NBIM Standard Process DefinitionProposals for the processes the NBIMS Committee will employ to produce the NBIM Standard and to facilitate productive use are discussed. A conceptual diagram to orient the user is provided. Components of this diagram correspond to section 5 chapters.Both the process used to create the NBIM Standard and the products are meant to be open and transparent. The NBIMS Committee will employ consensus-based processes to promote industry-wide understanding and acceptance. Additionally, the Committee will facilitate the process whereby software developers will implement standard exchange definitions and implementations tested for compliance. Finally, the NBIMS Committee will facilitate industry adoption and beneficial use through guides, educational activities, and facilitation of testing by end users of delivered BIMs.The Information Exchange Template, BIM Exchange Database, the Information Delivery Manual (IDM), and Model View Definition (MVD) activities together comprise core components of the NBIM Standard production and use process. The Information Exchange Template and BIM Exchange Database are envisioned as web-based tools to provide search, discovery, and selection of defined exchanges as well as a method of providing initial information necessary to propose and begin a new exchange definition discussion. The NBIMS workgroup formation phase teams will use the IDM, adapted from international practices, to facilitate identification and documentation of information exchange processes and requirements. IDM is the user-facing phase of NBIMS exchange standard development with results typically expressed in human-readable form. MVD is the software developer-facing phase of exchange standard development. MVD is conceptually the process which integrates Exchange Requirements (ERs) coming from many IDM processes to the most logical Model Views that will be supported by softwareapplications. Implementation-specific guidance will specify structure and format for data to be exchanged using a specific version of the Industry Foundation Classes (IFC or ifc) specification. The resulting generic and implementation-specific documentation will be published as MVDs, as defined by the Finnish Virtual Building Environment (VBE) project,3 the Building Lifecycle Interoperability Consortium (BLIS),4 and the International Alliance for Interoperability (IAI).5 The Committee will work with software vendors and the testing task team members to plan and facilitate implementation, testing, and use in pilot projects. After the pilot phase is complete, the Committee will update the MVD documents for use in the consensus process and ongoing commercial implementation. Finally, after consensus is reached, MVD specifications will be incorporated in the next NBIMS release.NBIMS AppendicesReference standards in the NBIM Standard provide the underlying computer-independent definitions of those entities, properties, relationships, and categorizations critical to express the rich language of the building industry. The reference standards selected by the NBIMSCommittee are international standards that have reached a critical mass in terms of capability to share the contents of complex design and construction projects. NBIMS V1-P1 includes three candidate reference standards as Appendix documents: IAI Industry Foundation Classes (IFC or ifc), Construction Specifications Institute (CSI) OmniClass ™, and CSI IFDLibrary ™.3http://cic.vtt.fi/projects/vbe-net/4 5Section 1 – Introduction to the National BIM Standard V 1 - Part 1Chapter 1.1National Building Information Modeling Standard™©2007 National Institute of Building Sciences. All rights reserved .The IFC data model consists of definitions, rules, and protocols that uniquely define data sets which describe capital facilities throughout their lifecycles. These definitions allow industrysoftware developers to write IFC interfaces to their software that enable exchange and sharing of the same data in the same format with other software applications, regardless of the internal data structure of the individual software application. Software applications that have IFC interfaces are able to exchange and share data with other application that also have IFC interfaces.The OmniClass ™ Construction Classification System (OmniClass or OCCS) is a multi-tableclassification system designed for use by the capital facilities industry. OmniClass includes some of the most commonly used taxonomies in the capital facilities industry. It is applicable for organizing many different forms of information important to the NBIM Standard, both electronic and hard copy. OCCS can be used in the preparation of many types of project information and for communicating exchange information, cost information, specification information, and other information that is generated throughout the facility’s lifecycle.IFDLibrary ™ is a kind of dictionary of construction industry terms that must be used consistently in multiple languages to achieve consistent results. Design of NBIMS relies on terminology and classification agreement (through OmniClass ) to support model interoperation. Entries in the OmniClass tables can be explicitly defined in the IFDLibrary once and reused repeatedly,enabling reliable automated communications between applications – a primary goal of NBIMS. ReferencesNBIMS References in this document represent the work of many groups working in parallel to define BIM implementation for their areas of responsibility. Currently there are four types of references.x Business Process Roadmaps are documents that provide the business relationships of the various activities of the real property industry. These will be the basis for organizing the business processes and will likely be further detailed and coordinated over time. The roadmaps will help organize NBIMS and the procedures defined in the InformationDelivery Manuals (IDMs).x Candidate Standards are documents that are candidates to go through the NBIMS consensus process for acceptance as part of future NBIMS. It is envisioned that Part 2 or later releases of the Standard will incorporate these documents once approved.x Guidelines have been developed by several organizations and include items that should be considered for inclusion in NBIMS. Since NBIMS has not existed prior to this, there was no standard from which to work, resulting in a type of chicken-or-egg dilemma.When formal NBIMS exists there will need to be some harmonization, not only between the guidelines and NBIMS, but also in relating the various guidelines to each other.While guidelines are not actually a part of NBIMS, they are closely related and therefore included as references.xOther Key References are to parallel efforts being developed in concert with NBIMS. Not part of NBIMS, they may, in fact, be standards in their own right.。

《建筑信息模型应用统一标准》是我国第一部建筑信息模型应用的工程建设标准，提出了建筑信息模型应用的基本要求，是建筑信息模型应用的基础标准，可作为我国建筑信息模型应用及相关标准研究和编制的依据。

本篇，将对《标准》的编制背景、编制过程、主要技术内容以及国际BIM标准进行系统介绍。

一、编制背景2011年，住房和城乡建设部在《2011-2015年建筑业信息化发展纲要》中明确提出，在“十二五”期间加快建筑信息模型（BIM）、基于网络的协同工作等新技术在工程中的应用，并特别要求“完善建筑业行业与企业信息化标准体系和相关的信息化标准”。

我国已在2010年将BIM的国际标准之一ISO/PAS 16739：2005《Industry Foundation Classes, Release 2x, PlatformSpecification (IFC2x Platform)》等同采用为国家标准GB/T 25507-2010《工业基础类平台规范》。

但我国的BIM应用工程建设标准仍属空白，无法为我国建筑工程建设各阶段BIM技术的应用实践及发展提供技术指导和规范。

2012年1月17日，住房和城乡建设部印发《2012年工程建设标准规范制订、编制计划》（建标[2012]5号），国家标准《建筑工程信息模型应用统一标准》（以下简称《标准》）列入制订计划，由中国建筑科学研究院会同有关单位进行编制。

二、编制过程2012年3月28日，《标准》编制组成立会召开。

住房和城乡建设部标准定额司、住房和城乡建设部标准定额研究所、住房和城乡建设部信息技术应用标准化技术委员会有关领导以及《标准》编制组成员出席了会议。

bim应用实施标准
BIM（Building Information Modeling，建筑信息模型）是一种数字化建筑设计和施工管理的方法，它可以提供建筑项目全生命周期的信息和协作平台。

虽然没有一个通用的全球标准，但许多国家和地区都制定了自己的BIM应用实施标准。

以下是一些常见的BIM应用实施标准：
1.美国国家BIM标准（NBIMS-US）：由美国国家BIM标准委员会制定，包括了BIM使用的信息要求、协议和最佳实践等内容。

2.英国BIM标准（PAS 1192系列）：由英国建筑信息管理协会（BIM Level 2）制定的一系列标准，包括了从设计到运营的BIM应用要求和流程。

3.欧洲BIM标准（EN ISO 19650系列）：由欧洲标准化委员会（CEN）和国际标准化组织（ISO）联合制定的一系列标准，包括了BIM应用的要求和流程。

4.新加坡BIM指南：由新加坡国家发展部和建筑与建设局制定的BIM应用指南，包括了BIM在建筑项目中的实施要求和指导。

除了这些国家和地区的标准外，还有许多其他国家和地区制定了自己的BIM 应用实施标准。

此外，一些行业组织和公司也制定了自己的BIM标准，以满足特定行业或组织的需求。

因此，在具体的项目中，需要根据所在国家或地区的要求，以及项目的特定需求，选择适用的BIM应用实施标准。

bim标准解读什么是BIM标准？为什么BIM标准如此重要？如何解读BIM标准的内容？本文将会一步一步回答这些问题，以帮助读者更好地理解BIM标准。

第一步：定义BIM标准BIM标准是指为建筑信息模型（Building Information Modeling）制定的一系列规范和准则。

BIM标准涵盖了BIM模型的建模流程、数据交换格式、协作要求、质量控制等方面的要求。

BIM标准可以帮助各方在建设项目中采用统一的BIM方法，并确保BIM数据的一致性和可靠性。

实现BIM的前提是:在建设项目生命周期的各个阶段不合的项目介入方通过在BIM建模过程中拔出、提取、更新及修改信息以支持和反响出各介入方的职责。

BIM是基于公共标准化协同作业的共享数字化模型。

1.1BIM概念理解BIM的概念分化为两个方面，BIM既是模型结果(Product)更是过程(Processs)。

（1）BIM作为模型结果(product)BIM作为模型结果，与传统的3D建筑模型有着实质的区别，其兼具了物理特性与功能特性。

其中，物理特性(Physical Characteristic)，可以理解为几何特性(Geometric Characteristic);而功能特性(Functional Characteristic)，是指此模型具备了所有一切与该建设项目有关的信息。

（2）BIM作为过程(Proeess)BIM是一种过程，其功能在于通过开发、使用和传递建设项目的数字化信息模型以提高项目或组合设施的设计、施工和运营管理。

你还不了解BIM标准吗？——从四种维度了解BIM标准来源丨万间科技发布丨绿盟_赵磊做了那么久的BIM，你还只是停留在建模阶段吗？再不督促自己学点就要Out了；BIM标准太多，看得云里雾里？不要着急，小万带你从四种维度了解BIM标准。

▲ 从业人员BIM标准导航图目前国内外关于BIM标准可以归为三个方面，分别是BIM理论体系、BIM软件研发和BIM工程应用三个方面。

就目前的BIM标准具体分析，可把BIM标准归为4类，如下：第一类：美国国家BIM标准NBIMS，分别于2007、2012和2015年发布了三个版本，NBIMS的内容涵盖了BIM理论体系、软件和应用三个方面，应该是到目前为止想要系统、深入学习BIM的同行最好的学习资料，从事不同BIM工作（包括BIM理论研究、软件开发、BIM应用）的同行可以根据自己工作需要和兴趣学习对应的内容，其中的BIM理论体系部分能够帮助读者全面和系统地认识BIM。

第二类：中国工程建设标准化协会建筑信息模型专业委员会（简称中国BIM标委会）主持编制的一系列P-BIM标准，内容为各个专业或任务的“软件功能与信息交换标准”，2017年6月15日发布了《规划和报建P-BIM软件功能与信息交换标准》（T/CECS-CBIMU 1-2017）等13项，这个系列标准覆盖BIM应用（其软件功能部分）和软件研发（其信息交换部分）两个方面，工程技术和管理人员一般而言只需要了解其BIM应用部分（软件功能）的内容。

第三类是主要给软件研发人员使用的标准，包括国际上的IFC/IFD/IDM/MVD/Omniclass/Uniclass标准，以及已经立项正在编制过程中的国家《建筑信息模型存储标准》和《建筑信息模型编码标准》，这些标准跟建筑业从业人员不是直接使用的关系，而是需要通过相应的软件工具去使用的标准，工程技术和管理人员基本上没有必要在这些标准上花时间，就如同大家使用手机和自动取款机没有必要了解它们各自执行的标准一样，相信如果把手机和自动取款机执行的标准拿出来，对绝大多数人来说都是天书，如果要掌握这些标准才能使用手机和自动取款机的话，估计也就没有多少人有能力使用手机和取款机了。

1.BIM模型深度标准及定义
美国建筑师学会（AIA）以“模型精度等级（LOD-Level of Detail）“来定义BIM模型中建筑元素的精度高低。

将LOD共分为5级：
1)LOD100——概念性：示以几何数据，或线条、面积、体积区域等。

2)LOD200——近似几何：以3D显示通用元素，包括其最大尺寸和用途。

3)LOD300——精确几何：以3D表达特定元素，具体几何数据的3D对象，包含尺
寸、容量、连接关系等。

4)LOD400——加工制造：即为加工制造图，用以采购、生产及安装；具有精确性特
点。

5)LOD500——建成竣工：建筑部件实际成品。

参考上述规定，再比照我国相关制图规范标准，特将传统设计阶段——方案阶段、初步设计阶段、施工图阶段、施工图深化阶段、运维阶段分别和LOD100、200、300、400、500对应。

BIM 能力成熟度模型CMM解读本周姗姗来迟，这次咱们来说说BIM生命周期的故事，这也是BIM CMM的第二个重要维度“Life Cycle View”。

建筑的生命周期很长，他涵盖了从设计、生产（供应链）、施工、运维几个阶段，在这每个阶段中，都会产生大量的信息和数据。

从BIM信息的完整性角度来看，这些都是BIM信息来源的重要环节，同时BIM数据在这每个环节是需要流转、协同和复用的。

在美国规范中，CMM关于生命周期应用的定义是这样的：目前，我们的BIM应用大部分还是集中在规划和设计阶段，大家主要还是关注了三维建模展示、管线综合、设计协同等方面的应用；一小部分BIM应用到了生产和施工阶段，比如：提取材料清单、造价成本管理、施工方案模拟、施工进度模拟等5D 应用。

极少部分关注了在运维阶段的应用。

同时，BIM CMM还非常强调数据的无缝流转和复用，每个阶段的数据是需要流畅地传递到下游的，一个阶段一个阶段进行数据叠加，这样才能使BIM数据的价值持续增长，而不是形成一个个独立的数据包。

当然，我认为在国内，BIM信息之所以无法很好的做到全生命周期和数据高效传递、复用，很大一部分原因是由于我们所处的行业是业务垂直型的生态体系，数据协同必然会遇到企业壁垒的问题。

抛开企业管理的问题，单从技术角度，我们如何能提升BIM在全生命周期的应用能力呢？以下是几个建议：1、提前做好数据规划数据规划是在BIM实施前非常至关重要的一个环节，在这个环节，我们需要明确定义出各个阶段需使用的数据内容、格式规范、数据来源、相互之间的对应关系，这样才能确保BIM信息既能满足各阶段使用方的需求，又不会造成数据冗余，并为数据协同、流转做好技术准备，事半功倍。
