Grounds Associates Ltd - Leica BLK360 Case Study

Tight deadlines and quick turnarounds are common hurdles for the vast majority of surveying projects and frequently pose a threat to the quality of deliverable assets. Today’s laser scanning technology not only seeks to increase the standards of the end results, but also aims to resolve these issues and ensure a simpler, smoother, and speedier experience for surveyors and laser scanning experts everywhere.

Alexandra Grounds, in her career as a geospatial consultant and as the founder of UK company Grounds Associates Ltd, is one of those who has experienced firsthand how the giant leaps in technology have transformed surveyors’ workflows. Specialising in laser scanning, surveying and engineering, and photo documentation, Alexandra is accustomed to working with tight deadlines and identified that the Leica BLK360 imaging laser scanner could help her in her projects and client work.



In the run-up to the 2019 World Economic Forum (WEF) in Davos, Switzerland, Grounds Associates Ltd was commissioned to assist in the set-up of a private company event for 250 guests. Knowing the exact dimensions of the space was key in being able to outline, design, prepare, and assemble all the necessary components in a narrow timeframe of just three weeks, including fixtures and lighting. In order to meet the deadline and scan the space in the available slot of only two days, it was crucial that the technology chosen to do the job was able to deliver near real-time results, as well as being portable and easy to use. For this reason, the Leica BLK360 was used by Grounds Associates Ltd to complete this project and was transported from London to Switzerland to execute the scans of the space and deliver an accurate 3D model.


To date, the BLK360 has been used in countless construction and design projects worldwide and is currently known to be the smallest 3D imaging laser scanner on the market, measuring 165mm in height and 100mm in width. “An important aspect for me was being able to transport the BLK360 as part of my hand luggage,” says Alexandra. “This is why it’s so important to choose and use the right tool for each project.”



Once in Switzerland, Alexandra spent two days on-site with the BLK360 and gathered a total of 100 scans, an average of 50 per day. “I wanted a high density of points, so I set up the BLK360 every half a metre to get through doorways and obtain maximum accuracy and detail,” says Alexandra. “There were also mirrors everywhere, which made it more difficult to capture the space, but the BLK360 was perfect for the overall process.”


After completing the on-site work within the narrow time frame, Alexandra processed all scans with the Autodesk® ReCap™ Pro software and joined the three separate data sets together, including indoor and outdoor scan data.

With all venue scans captured on Saturday, and the final data and registration completed on Sunday morning, I was able to send the client a unified and usable data set on that same Sunday evening -  48 hours after arriving on-site.

When speed, accuracy, and detail are the order of the day, the BLK360 delivers like no other laser scanning solution, allowing surveyors and laser scanning experts to not only meet project requirements and excel in the quality of their deliverables, but also enjoy the entire process.
