Point clouds are among the most powerful tools in modern architecture. They provide precise, digital images of existing buildings and sites. They enable a new level of planning quality, especially during renovations, conversions, or the creation of as-built plans.
But what exactly is a point cloud? And why is it indispensable for architects, specialist planners, and project developers today?
📌 What is a point cloud?
A point cloud is created using 3D laser scanners. These capture millions of measurement points in space – every detail is digitally measured. These points make a three-dimensional, dimensionally accurate image of reality.
Whether it’s an entire building, a roof structure, a service floor, or a historic hall, The point cloud accurately depicts the actual conditions – much more accurately than conventional measurement methods.
📐 Why point clouds are changing planning
1. Planning reliability instead of gut feeling
With a point cloud, you have a digital 1:1 model of the building. No more estimating, no more remeasuring, no more nasty surprises. This is a huge advantage, especially for older buildings or complex structures.
2. Perfect foundation for CAD & BIM
Precise 2D plans or 3D models can be generated directly from the point cloud – ideal for further processing in CAD or BIM systems. Architects and specialist planners can thus digitally build on the existing structure.
3. Transparent communication in the project
All participants – from the client to the structural engineer – have access to the same precise data. This reduces misunderstandings, saves time, and makes planning processes more efficient.
🛠️ Typical applications for point clouds
Point clouds are primarily used where existing data needs to be precisely recorded and digitally processed:
Renovations and conversions
Heritage preservation projects
Measurements of industrial facilities
Creation of verifiable as-built plans
Scan-to-BIM processes
Building documentation for developers, authorities, or courts
🤝 How we work with point clouds
At Shoai Architectural Office, we use state-of-the-art laser scanning technology to generate precise point clouds – both indoors and outdoors. From these, we create:
Custom architectural plans
As-built models for BIM processes
Legally compliant area calculations according to DIN 277, GIF, and WoFIV
Visual building documentation in NavVis Ivion
This is how a scan creates concrete added value for your planning – quickly, transparently, and efficiently.
🔐 Why precise data is worth money
Incorrect measurements, undocumented components, or unclear floor heights are common causes of addenda, planning errors, and cost explosions. Point clouds help minimize these risks from the start.
Especially for complex projects, the use of point clouds is not only sensible, but also economically prudent – because every decision is based on reliable, verifiable data.
🧭 Conclusion: Point clouds as the key to digital planning
Point clouds bring a new quality to architecture. They make existing structures tangible, measurable, and plannable – with a precision that traditional methods cannot achieve.
👷♀️ At Shoai Architects, we combine 3D laser scanning, CAD planning, and digital twins into a comprehensive solution for your project. Whether it’s an inventory, area calculation, or renovation planning – with point clouds, you can rely on security.
