Bringing BIM4ALL

建筑信息建模（BIM）在全球的采用和受欢迎程度上稳步提高。定义为“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”经过Leica GeosystemsBIM Field Trip，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.

作为Leica Geosystems 3D激光扫描仪，总站和GNSS解决方案的用户，BIM4Albob applel每年平均为全球200多名客户提供服务，每年平均有400个BIM项目。该公司已经为自己取名，通过领先的全球公司登陆帐户，同时还支持更多本地AEC公司。

“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管理

• BIM Coordination

• 3D激光扫描

• 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 for new construction of bridges in Denmark

• 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,”said Voortman.

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.

Recently, multiple companies in the Netherlands contacted BIM4ALL to document sewer pits across the whole country. Throughout the nation, there are around 80 million of these sewer pits and at least 10% of them needs to be replaced, due to corrosion from hydrogen sulfide gas.

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。

“使用激光扫描仪，我们能够在大约半小时内捕获这些坑。这样，我们将人员拒之门外，从而导致更安全的行动，”said Voortman.“The costs go down, time savings go up, and the environment is significantly less disturbed.”

BIM4ALL used theLeica RTC360 3D laser scannerto document 5-metre-deep pits. Capturing 2 million points per second, each pit only took 15 to 30 minutes to complete. In conjunction, theLeica图标GPS 70 T GNSS接收器与荷兰坐标系一起使用，以准确定位和测量凹坑的深度。借助能够准确的倾斜补偿的惯性测量单元（IMU），工作人员能够轻松地测量坑中难以到达的区域。

详细的扫描已在Leica Cyclone point cloud processing softwarethen exported using theLeica CloudWorx for 3D Reshaperplugin to visualise meshes for the client’s review. This reduces noise in the point clouds, enabling clients to clearly see the corrosion in the pits and allowing them to precisely create the needed composite molds.

“We’ve been working with Leica Geosystems solutions for one year now, and we can assure you that they provide the right tools to optimise our work process even further,”said Voortman.“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 gains even more and more users worldwide. Even several governments are now requiring BIM for all their construction or renovation projects. Firms like BIM4ALL and specialists like Voortman prove, with their knowledge and various services, the high potential and endless possibilities of the working method and the new technologies for the construction industry.

Creating virtual reality with laser scanning

As part of the Brevo Group, BIM4ALL has direct access to virtual, augmented and mixed reality creations through its sister company,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。”said Voortman.“As a member of the Brevo Group, it’s great to bring new technologies into the construction industry that can help them to make smarter and more informed choices, by optimizing the process and reduce (building)costs.”
