Bringing BIM4ALL

Building Information Modelling (BIM) has steadily increased in adoption and popularity around the globe. Defined as“一个经过验证的过程，可以按时和预算保持项目，减少返工并提高可预测性和盈利能力”byLeica Geosystems BIM实地考察，这个基于3D模型的系统正在节省建筑师，工程师和建筑（AEC）行业专业人员的大量时间和成本。

One firm in the Netherlands fully believes in this concept and has dedicated itself entirely to the endeavour.BIM4ALL, a member of theBrevo Group, is an innovative engineering firm on a mission to share BIM with all areas of the AEC industry. Committed to optimise the processes of building projects, BIM4ALL reduces construction errors and decreases building costs through its knowledge and experience with BIM.

As users of Leica Geosystems 3D laser scanners, total stations and GNSS solutions, BIM4ALL serves more than 200 clients worldwide with an average of 400 BIM projects each year. The company has made a name for itself, landing accounts by leading global companies, while also supporting more local AEC companies.

“As our tag line states, we are committed to ‘building value’ with our customers and in the industry overall,”BIM4ALL的3D激光扫描经理Jasper Voortman说。“Our services improve building construction, helping to reduce mistakes in the field by creating precise 3D models in the office.”

各种项目的服务

Though the firm specialises in BIM, there are many facets within that concept. BIM4ALL prides itself on providing a full portfolio to its clients that brings added value and consultation. The services are:

• BIM modelling

• BIM Management

• BIM Coordination

• 3D Laser Scanning

• Bim Academy（Autodesk和Solibri的合作伙伴）

• BIM Visualisations (in cooperation with Studio X)

这些服务已在荷兰和国际上使用。BIM4ALL的一些项目包括：

• BIM for a new housing development in The Hague

• BIM在丹麦新建筑的新建筑

• BIM coordination and management for government buildings in the Netherlands

• BIM coordination with 3D laser scanning and BIM modelling of a new railway station in the Netherlands

• 使用3D激光扫描和BIM建模进行BIM协调，用于翻新阿姆斯特丹一家主要百货商店

“Our customers call us ‘BIM masters’, and we’re proud of that. We’re innovating the building sector. Like the name of our firm, we believe everyone can benefit from BIM, and it’s our goal to share this technology and our knowledge, to make everything once thought was impossible, possible,”沃特曼说。

Taking laser scanning below ground

BIM is not only useful for the construction of new buildings, but also for the renovations of buildings and objects. To do this, it is a key step to measure the real world and capture it into a 3D model. The best way to do this is by laser scanning. This enables BIM practitioners to accurately capture environments in detail for as-built checks of renovations, retrofits, validation and documentation.

最近，荷兰的多家公司与BIM4ALL联系，记录了整个国家的下水道坑。在全国范围内，由于硫化氢气的腐蚀，大约有8000万个下水道坑，其中至少有10％需要更换。

当使用传统的挖掘矿坑手段时，成本会过高，并且会对环境构成风险，更不用说这样一个项目的长时间了。但是，使用激光扫描，可以制作复合模具在不到一天的时间内翻新腐蚀区域。

“With our laser scanners we are able to capture each of these pits in about half an hour. That way we keep personnel out of the pits, which leads to safer operations,”沃特曼说。“The costs go down, time savings go up, and the environment is significantly less disturbed.”

Bim4All使用了Leica RTC360 3D laser scanner记录5米深的凹坑。每秒捕获200万点，每个坑只需15到30分钟即可完成。结合在一起Leica iCON gps 70 T GNSS receiverwas used with the Dutch coordinate system to accurately locate and measure the depth of the pits. With an inertial measurement unit (IMU) that enables accurate tilt compensation, the staff was able to easily measure hard-to-reach areas of the pit.

The detailed scans were processed in徕卡气旋点云processing software然后使用Leica CloudWorx for 3D Reshaper插件可视化网格以进行客户的评论。这减少了点云中的噪音，使客户能够清楚地看到坑中的腐蚀，并使其精确地创建所需的复合模具。

“我们已经与Leica Geosystems Solutions合作了一年，我们可以向您保证，它们提供了正确的工具来进一步优化我们的工作流程。”沃特曼说。“The mix of technologies Leica Geosystems provides helped us create the added value for our customer that we strive to provide in every project.”

BIM在全球范围内获得越来越多的用户。甚至几个政府现在都需要BIM来完成其所有建设或翻新项目。像Bim4all和Voortman这样的专家等公司证明，他们的知识和各种服务，工作方法的高潜力和无尽可能性以及建筑行业的新技术。

Creating virtual reality with laser scanning

作为Brevo Group的一部分，BIM4ALL可以通过其姊妹公司直接访问虚拟，增强和混合现实的创作Studio X.

因此，毫不奇怪的是，当下水道坑的承包商问代表现实体验的可能性时，Studio X愉快地介入了。

由于从RTC360扫描中提取了高动态范围的图像，因此Studio X的团队能够创建通过Oculus VR耳机来创造虚拟现实体验。

“通过能够通过VR（虚拟现实）体验扫描，我们的客户被他们清楚地看到腐蚀程度的程度而震惊。”沃特曼说。“作为Brevo集团的成员，很高兴将新技术带入建筑行业，可以通过优化流程并降低（建筑）成本来帮助他们做出更聪明，更明智的选择。”
