自八十年代初，我曾亲自参与不同行业信息技术的管理工作。目前我的工作是Tekla的BIM大使（如果你喜欢也可以称为传播者），我的工作包括促进和提升一个真正的基于BIM的内外流程。我也大量参与buildingSMART的工作，这是这个一系列关于建筑业信息管理的博客的开端。

什么是以基于BIM的流程？或者什么是真正的BIM？看来，今天大部分人对于BIM都有了自己的定义与看法。BIM的“舞台”正在积极搭建当中，我们正进入一个新的时代，这里BIM在建筑业已经是家喻户晓了。回到BIM的缩写，通常的理解是BIM是Building Information Modeling的缩写，重点在于创建基于模型的信息，对这些信息在创建之后该如何使用的关注相对较少。BIM的主要作用是可以更高效地创建文档，这只是从过去二十年CAD的作用就可以推断出来。

有了基于BIM的流程，我是指建造过程中，大部分信息以结构化的数字信息方式在各项目的参与方之间进行创建了、存储与分享，例如，信息在接受终端可以自动处理，甚至几乎不需要人工干预。

为了实现这点，我认为我们需要将BIM的含义推广至包括建筑信息管理（Building Information Management）。在IDM（Information Delivery Manuals）领域，有一些工作需要完成，目前这方面的尝试远远不及所需要的水平。还有很大一块领域需要被囊括在BIM的含义中，例如永久存储、交易、所有权、权力以及很多其他方面内容使得基于BIM的流程能够实现。

传统来看，管理信息在建筑业是一个非常隐性的活动。它一般被等同于管理文档，因为即使在今天，大部分技术资料被整理成文档。说它“隐性”，我指的是它内置于整个建筑业的价值链中，如什么文档由何人创建，将如何分配、更新与存储，没有人会对这些考虑很多，但它或多或少就这样发生着。但当我们进入BIM世界，这些事件就会有很大的不同：没有传统，勿须依赖既有的工作方式或指导；很多事情需要重新定义。

这不是一个简单的流程：技术仍然在强劲的发展之中，用户公司的竞争力依然在不断更新，建模各参与方的角色仍然会有发改变……在这个领域，还有很多问题需要解释，而且在向基于BIM的流程过渡时还会出现很多的问题与不确定性。

I have personally been working with managing technical information in different trades since early eighties. Currently I am working as a BIM Ambassador (or Evangelist if you like) at Tekla Corporation, and my job involves promoting and advancing a true BIM-based process both externally and internally. I'm also heavily involved in buildingSMART’s work. This is the start of a series of my blogs about information management in construction.

What does BIM-based process, or in fact BIM mean? It seems that today most people have their own definition and perception of BIM. The BIM ‘arena’ is under heavy development, and we are clearly entering a phase wher BIM is becoming a household item, in terms of the industry. But back to the acronym: the usual meaning is Building Information Modeling, and the focus of activity has been in creating model-based information but not so much in how that information is used after it has been created. The main use of BIM has been to create documents more efficiently, just extrapolating what has been done with CAD for twenty years.

With a BIM-based process I mean a construction process wher most of the information is created, stored and transmitted between project parties as structured digital information, i.e. information that can be automatically processed in the receiving end, eventually with very little human intervention.

To achieve this, I feel we need to expand the meaning of BIM to also include Building Information Management. Some work has been done in this area in the form of IDM (Information Delivery Manuals), but these attempts are quite feeble and nowher near what is needed. There are big areas that need to be covered, like persistent storage, transactions, ownership, rights, and many more to enable BIM-based process. Another strong technology entering the BIM arena is Cloud.

Managing information has traditionally been a very implicit activity in the construction industry. It has equaled to managing documents, because even today, most of the technical information is handled as documents. When I say implicit, I mean that it is built into the fabric of the whole construction value chain what documents are being created and by whom, how they are distributed, updated and stored; nobody considers this very much, it more or less just happens. But when we come to the BIM world, things are VERY different: we have no tradition, no established way of working or instructions to rely on; many things need to be re-invented.

This is not an easy process for many reasons: technology is still developing strongly, the competence at user companies is not up to date, some changes in the roles of modeling parties are needed… Stay on this channel as I am soon going to cover some of the issues, possibilities and questions arising from the transition to BIM-based processes.
