Laser Scanning in Southern California

SLAM scanning is becoming more commonplace in the surveying industry due to the ease of use, accuracy, and versatility of the handheld devices. As the technology continues to grow, so do the benefits of handheld scanning compared to traditional means of capturing the measurements of a building. Documenting large spaces is now as simple as walking around the property to capture a pointcloud, saving both time and money for surveyors and their clients.

Singapore is home to some of the most profitable financial services, manufacturing and oil-refining corporations in the world. But with its accomplishments come some very specific challenges for a city-state which is limited by space but still demanding growth.

Determined to future-proof Singapore’s success, the country has embarked on one of the most ambitious digital twinning projects the world has ever seen – creating a dynamic 3D city model and collaborative data platform, including 3D maps of the region.

At the initial stage of the project it quickly became apparent that aerial imagery alone would not be able to capture ‘void decks’ – open spaces typically found on the ground floor of the city’s apartment blocks. These areas, which are sometimes underneath the tower block structure, are used for everything from games areas, bicycle parking, hosting wedding receptions and wakes, and, as estates grow, facilities such as shops, medical centres and even schools.

In the face of fierce competition, GeoSLAM’s ZEB Revo was selected as the most innovative and efficient solution to collect data from these important community spaces.

A huge time saving exercise which would ordinarily have taken 40 times longer using traditional surveying methods

With a handheld “go-anywhere” ZEB Revo, field teams quickly captured a dense and accurate point cloud of an entire void deck, which was then used to model the deck geometry and incorporate this into the existing building models.

376 buildings with void decks were scanned using the ZEB Revo, taking approximately 100 hours – an enormous time-saving exercise which would ordinarily have taken up to 40 times longer using traditional surveying methods.

The ZEB Revo is often used alongside terrestrial hardware as the products are highly complementary. The data output can be easily combined through geo-referencing or scan-to-scan matching and then used to build complete 3D models. In this instance, the combination delivered highly detailed and rapid results while significantly minimising costs too.

“In the city of Belo Horizonte, there is a distinct mix of contemporary, classic and historic buildings on display, making it a really attractive destination to visit. What comes with the architecture on offer however, is the need to preserve it for tourists and future generations to enjoy.

Often the fragility of buildings or lack of resources means that many buildings go untouched for decades, leaving them to crumble. It’s my job to ensure these relics remain.

When the chance to retrofit electrical installations and a fire prevention plan to a 130-metre art deco skyscraper, the Acaiaca Building, became available, the team at Paragram knew we had to be involved.

We were very impressed with the quality of information captured by the ZEB Revo.

Built in the 1940s and once used as a nightclub, cinema, shops and air-raid shelter, the building required some attention in order for it to meet safety standards. Having initially planned to measure the 8,357 square metre building using manual survey methods, estimates told us this would have taken three employees over 40 hours to complete an as-built structure.

Working alongside contractors at Criar Projetos E Consultoria, Paragram decided to use GeoSLAM’s ZEB Revo, known for its ability to quickly generate images to within a few centimetres of accuracy. With the handheld device, the job was expected to take around 10 hours in total, reducing the workload dramatically.

Acaiaca Building

With just two operatives and in under 10 hours, we managed to complete a scan of the building’s interior, with one walking through the building holding the device and another taking a photographic record. This innovative way of working meant we were able to gather much more information than first anticipated, including the registration of beams and roof trusses, electrical installations and engine room areas.

The ZEB Revo is a real game changer for the architecture industry.

As a team, we were very impressed with the quality of information captured by the ZEB Revo, which was easily incorporated into a BIM representation using Revit software.

Almost every renovation project is governed by strict time constraints, but with GeoSLAM’s device and its ability to rapidly scan large areas, it is a real game changer to our industry. With products like this at our disposal, I am excited about what the future will hold for heritage buildings in need of a little TLC.

Established in 2001, Builders by Design Ltd are a multi-disciplinary design and construction company based in London. Their expertise and services are mainly in the residential sector for new builds, conversions, and extensions. The core business is a combination of collaborations via competitive tender, negotiated contracts and design and build. They also have a bespoke joinery workshop facility in Park Royal, designing and fabricating furniture, kitchens, windows and doors. One of their greatest achievements to date, was being selected as the main contractor for Peacock House, a new build in Aldeburgh, Suffolk which was awarded a National and Regional RIBA award and was longlisted for Grand Designs House of the Year in 2017.

We spoke with Director, Nick Phillips, following their recent purchase of their GeoSLAM ZEB Revo RT to get an understanding of how this was helping to support their business. Previously, external companies were appointed to produce the 2D surveys which proved to be expensive, time consuming and not without errors and omissions.

Traditional 2D surveys instructed, would only take limited data, meaning important details on areas, such as staircases were incomplete. Inevitably there were times during the later stages of design and construction that the absence of such details required re-working of proposals. The manual process was also not very efficient, as it could take a full day for 1 person to survey a 3-bedroomed house and several weeks to receive the results. Nick identified that projects with existing structures should always start with comprehensive 3D data, which led to the purchase of the GeoSLAM ZEB Revo RT to enable 3D data capture in-house.

Before purchasing the ZEB Revo RT, other scanners were considered, such as terrestrial and static, but there were time and software limitations to adopting these more traditional systems. Using these methods was not efficient enough for Builders by Design, as they needed technology with speed, accuracy, and ease of use. Using GeoSLAM handheld solutions meant they could complete between 6-8 scans a day, with the accuracy they needed, whereas a static scanner may only achieve 1-2 scans a day. With current Covid-19 restrictions, having a single operative on site for only 30-minutes to complete the internal and external data capture can bring logistical advantages where a property is still occupied.

Builders by Design have integrated the ZEB Revo RT as an integral part of their digital workflows, providing all the stakeholders with dynamic visualisation material for project design. They use the ZEB Revo RT to scan the 3D point cloud, importing the data into CAD software to create 3D models and 2D planning documentation for the design team. Working in 3D environments together with other visualisation tools has also created a transparency and understanding of design intent between the Architect, the site team and the client that could not have been achieved with 2D plans, sections, and elevations.

Having utilised the GeoSLAM ZEB Revo RT in-house to identify the many benefits to the business, they plan to collaborate with external Architectural and Design practices undertaking their own digital transformation journey, to build templated 2D documentation of existing buildings, 360° site photos, 3D model and bespoke CAD packages. In closing, Nick emphasised that:

Powering the future of SLAM

As the adoption of SLAM rockets, and new applications for mobile data capture are discovered each day the value of SLAM is being proven across businesses of all shapes and sizes. GeoSLAM technology continues to break barriers and the ever-increasing profile of SLAM users grows each day.
