On a typical construction project, a lot of information is produced. That information is often unstructured, poorly co-ordinated and hard to find. The result is an extra 20-25% on the cost of delivering your built environment. If we take more care and have more integrity around how we structure this data, we can eradicate the waste from the process. That will improve efficiency and bring us time and cost savings.

【unstructured：缺乏結構性】
【integrity ：完整性的】
【eradicate：根除】
【efficiency：效率】

The key to well-structured data these days is a Common Data Environment; an online place for collecting, managing and sharing information amongst your team working on a project. A Common Data Environment can take on many forms, depending on the size or type of project you』re working on. It could be a project server, an extranet or a cloud-based system. The important thing is that its digital, that everybody in your team has access to it, and that it can be easily sub-divided into areas. It needs to be a collaborative and well-managed space for sharing work.

【amongst ：在...之中】
【take on：呈現】
【extranet ：外聯網】
【access ：使用，接近】
【sub-divided：細分】

Here we』re going to look at the Common Data Environment format as set out in the British Standard PAS 1192-2, the guidance document for delivering projects at BIM Level 2.

We start with a single shared area and the Client』s authorised Employer』s Information Requirements (EIRs). Once the project team are appointed, work takes place within an area that was already defined in BS 1192, back in 2007.

【Employer』s Information Requirements (EIRs)：僱主信息要求】
【BS 1192：英國國家標準，Collaborative production of architectural, engineering and construction information – Code of practice 建築、工程和建築信息的協同生產 – 守則】

Design teams and other project contributors work in their own 『Work In Progress』 areas, developing and honing their graphical and non-graphical information. Once checked, that information is approved and moved to the shared area for other parties in access and use in the creation and development of their contributions. At BIM Level 2, whilst others may re-use information, the ownership and power to change the information remains with its originator.

【honing ：加工】
【approved ：批准】
【originator：創作者、發起者】

At key project stages and decision points – like the end of work stages, Planning approval or construction issue – the Employer or Employer』s Agent approves and signs-off information before moving it to the 『Published』 area. It』s important to check here that the information provided aligns with the Client』s stated requirements.This information can then be used to engage specialists, who work in similar 『Work In Progress』 areas to the design team before sharing their approved contributions.

【aligns with ：與...一致】
【engage：銜接】
【specialists：專家】

As each project milestone is met, published information is moved to the archive area for future reference and use.

【milestone：里程碑】
【reference：引用】

Effective use of a Common Data Environment will build an accurate and well-structured data set – known as a 『Project Information Model』 (PIM) as the stages progress. Once verified, this published documentation and data is used in the asset management phase and known as an Asset Information Model (AIM). It is the gates and sign-off procedures at each point that allow data to flow between areas.

【accurate：精確的】
【progress：前進】
【verified：證實】

Revision control is simple, production information is right first time and the cost of producing it is reduced.

【revision：審閱】
