Get Answers to Questions About 3D Measured Surveys
A 3D Measured Survey is a highly accurate and comprehensive method of digitally capturing the precise dimensions and intricate details of a building or site. Unlike traditional 2D surveys, which provide flat plans and elevations, a 3D survey creates a complete digital replica, often referred to as a "digital twin."
This process typically uses advanced technology such as 3D laser scanners and LiDAR (Light Detection and Ranging). These devices emit millions of laser points per second, which bounce off surfaces and return to the scanner. By measuring the time it takes for each pulse to return, the scanner can calculate the exact XYZ coordinates of millions of data points.
The result is a highly dense dataset known as a point cloud. This point cloud is a three-dimensional representation of the space, showing every surface, feature, and detail with millimetre accuracy. This raw data can then be processed into various useful deliverables, including accurate 2D floor plans, elevations, cross-sections, and detailed 3D models. These outputs are essential for architects, engineers, and designers, providing the foundational data needed for everything from renovation planning to new construction projects, and are crucial for ensuring accuracy and preventing costly errors.
A 3D Measured Survey is an essential tool for a wide range of professionals, fundamentally because it provides unparalleled accuracy and detail. The most common need is for architectural and construction projects. When planning a renovation, extension, or a new build, having a precise digital model of the existing site is critical. It allows architects and designers to create plans that fit perfectly, identifying any potential clashes or issues before construction begins, which saves time and money on costly re-work.
Beyond construction, these surveys are invaluable for heritage and conservation projects. They provide a non-invasive way to meticulously document historical buildings, capturing every ornate detail and complex geometry for preservation and restoration.
For facility managers, a 3D survey creates a "digital twin" of a building, which is a powerful asset for ongoing management, maintenance, and space planning. In essence, anyone who needs to understand, modify, or document a physical space with absolute certainty will benefit from a 3D Measured Survey. The technology eliminates the risk of human error, reduces the need for multiple site visits, and provides a foundation of reliable data for every stage of a project.
A traditional survey is a manual and labour-intensive process that relies on tools like tape measures, theodolites, and total stations. Surveyors capture a limited number of specific points to create a two-dimensional representation of a building, such as floor plans or elevations. This method is often time-consuming, requires multiple site visits, and is susceptible to human error. It provides a static, flat snapshot of a building's geometry.
In contrast, a 3D Measured Survey uses advanced technology, typically a laser scanner, to rapidly capture millions of data points from every angle of a structure. This creates a highly detailed "point cloud," which is a comprehensive, three-dimensional digital model. The key differences lie in efficiency and accuracy; a 3D survey can be completed in a fraction of the time, provides millimeter-level precision, and captures intricate details that would be missed by traditional methods. The resulting data can be seamlessly integrated into modern software for advanced design, analysis, and visualisation.
The primary technologies used for 3D building surveys are laser scanning and photogrammetry.
Laser scanning, also known as LiDAR (Light Detection and Ranging), is a highly accurate and efficient method. A laser scanner emits millions of laser beams per second, and a sensor measures the time it takes for each beam to reflect back from a surface. By doing this from multiple positions, the device can create an incredibly dense and precise "point cloud" of a building. This point cloud contains millions of data points, each with specific XYZ coordinates, effectively creating a detailed digital twin. Laser scanners are especially valuable for their speed and ability to capture intricate details with millimeter-level precision.
Another key technology is photogrammetry. This method uses a series of overlapping photographs taken from multiple angles of the building. Specialized software then analyzes the images and uses principles of perspective and parallax to stitch them together and generate a 3D model. While often less precise than laser scanning, photogrammetry can be a more cost-effective option and is particularly useful when mounted on drones to capture hard-to-reach areas like rooftops or large facades. Often, these two technologies are combined to get the best of both worlds: the precision of laser scanning and the visual detail of high-resolution photographs.
For a 3D building survey, you'll receive a variety of deliverables, with the most common being point clouds, 2D drawings, and 3D models. These deliverables are created from data captured using technologies like laser scanning or photogrammetry.
The duration of a 3D building survey is highly variable and depends on a number of key factors. There's no one-size-fits-all answer, but you can generally break the process down into two phases: the on-site work and the post-processing work. The team at SIAD Studio will be able to provide you with a more accurate timeline once we know more about your project.
Here at SIAD Studio, we understand that every project is unique, and so is its budget. We don't have a one-size-fits-all price list because the cost of a 3D building survey depends on several key factors. Our goal is to provide a transparent quote that's tailored to your specific needs, ensuring you only pay for the deliverables and level of detail you truly require.
Factors Affecting the Cost
-
Size and Complexity of the Building: This is the most significant factor. A large, multi-story commercial building with intricate features will naturally cost more to survey than a small, simple residential property. The on-site time required for data capture and the subsequent processing time are directly proportional to the building's scale and complexity.
-
Required Level of Detail (LOD): What you need the survey for determines the level of detail. A basic survey for simple planning permission is a different undertaking than a detailed BIM model for complex architectural design or structural engineering. The more granular the data and the more intelligent the final model, the higher the cost will be due to the increased time and expertise required for post-processing.
-
Type of Deliverables: We offer a range of deliverables, from raw data to a fully detailed BIM model. The cost is directly tied to your choice of output:
-
Point Cloud: This is the raw, unprocessed data. It's the most cost-effective option if you have the software and expertise to process it yourself.
-
2D Drawings: We can generate detailed 2D floor plans, elevations, and sections from the point cloud.
-
3D Models: Our 3D models range from simple visual representations to comprehensive BIM models that include structural and mechanical information. A detailed BIM model is the most valuable and therefore the most expensive deliverable.
-
-
Project Location and Accessibility: The location of the property and its accessibility can influence the cost. Factors like travel time, congestion charges, and how easily our team can access all areas of the building will be taken into consideration.
-
Project Timeline: If you require an expedited turnaround for your deliverables, we can often accommodate this for an additional fee.

Our Process for Providing a Quote
To give you a precise quote, we follow a simple and efficient process:
-
Initial Consultation: We begin with a conversation to understand your project. We'll discuss the building's size, your project's purpose, and the specific deliverables you need.
-
Site Assessment: Based on our discussion, we'll determine the best on-site strategy and estimate the time required for data capture.
-
Tailored Proposal: We will then provide you with a comprehensive, fixed-fee quote that outlines all the costs, the scope of work, and the timeline for delivery.
While we can't give a definitive price without knowing the specifics of your project, you can expect that a basic 3D survey for a standard residential property will be far more affordable than a comprehensive, high-LOD survey of a large commercial building. By focusing on your specific needs, we ensure you receive a cost-effective solution with no hidden fees.
