Mastering Laser Scanning Surveys: A Step-by-Step Guide

Michael Gallie & Partners specialise in measured building surveys using laser scanning surveys for the whole measurement process. Below is an outline guide of our process of producing a laser scanning survey.


Unlocking Accuracy with Advanced Laser Scanning Techniques

In today’s technologically advanced world, accuracy has never been more crucial. Laser scanning surveys epitomize these qualities by providing a comprehensive view of structures and terrains. Let’s walk through the meticulous process of executing a successful laser scanning survey:

1. Establishing a Solid Foundation: Survey Control and Grid/Datum Coordination

Every laser scanning survey starts with a robust survey control framework, facilitated by the most cutting-edge survey equipment available. To anchor the survey to the Ordnance Survey’s national grid and datum, our skilled surveyors deploy two accurate GPS receivers, diligently working in tandem for an uninterrupted two-hour window.

2. Diving into the Action: In-Depth On-Site Laser Scanning

At the core of Michael Gallie & Partners’ offerings is our unwavering commitment to laser scanning for all building measurements. We ensure that every nook and cranny of the structure is scanned, leveraging the most sophisticated laser scanners in the industry. Picture a dedicated surveyor, positioning a laser scanner atop a sturdy tripod, moving strategically across the premises, each setup spanning a brief 1-2 minutes. Occasionally, for certain survey types, we might employ a handheld laser scanner for swift, albeit slightly less accurate, data capture. Need a splash of color in your point cloud? Add just a minute more per setup. And yes, our mobile devices can concurrently capture vivid imagery alongside the point cloud data.

3. From Field to Screen: Transformative Laser Scanning Data Processing

With the on-field data collected, it’s time for some digital magic. High-performance computers, paired with specialized software, work in unison to process the laser scan survey. This data aligns seamlessly with the designated site grid & datum, resulting in a meticulously registered point cloud. Segmented floor-wise, this data lays the groundwork for CAD & 3D modelling Bonus: For projects demanding richer visual insights, we provide HDR colour/Greyscale visuals, culminating in an interactive TruView for each setup. TruView, an online viewer platform, offers a panoramic, measurable tour of the entire site, proving invaluable during periods like the Covid-19 lockdowns.

4. Breathing Life into Data: Crafting 2D CAD & 3D Models

The journey of the laser scanning survey data continues as it’s integrated into CAD for 2D outputs or channelled into BIM authoring tools like Revit for 3D modelling. Our dedicated CAD & modelling squads synergize, working in parallel on different building sections, periodically syncing to the central model, ensuring seamless consistency and zero redundancy.

1. Why opt for Laser Scanning Surveys over traditional methods?

Laser Scanning Surveys offer higher accuracy, detail, and speed, making them ideal for intricate and vast projects.

2. What’s the significance of the Ordnance Survey’s national grid in this process?

It provides a standardized reference system, ensuring the accuracy and consistency of the survey across different locations.

3. How does TruView enhance the laser scanning survey experience?

TruView offers a 360° panoramic visual tour, allowing users to explore and measure site conditions from the comfort of their screens.

4. Can laser scanning capture both interior and exterior details of a structure?

Absolutely! The technology captures comprehensive details, both inside and out, providing a holistic view of the structure.

5. How are the laser scanning data and outputs shared with clients?

Clients receive access to all deliverables through a secure and straightforward weblink download.
