Exterior Design DX: Improve Work Efficiency with LRTK Cloud Integration

Introduction: Do you feel inefficiencies in exterior work?

Do you find moments of inefficiency in exterior (landscaping) design or construction management? For example, on-site surveys often involve measuring dimensions manually with tape measures and levels and recording them on paper drawings or notes... Back at the office, re-entering those measurements into CAD software can consume time decoding notes or discovering missed measurements. During pre-construction meetings, conveying the finished image to clients using only plans and catalog photos has its limits, and mismatched expectations often lead to rework. Additionally, progress reporting from the site can be burdensome—site managers must take photos and email them or compile documents, which all takes time.

In recent years, DX (digital transformation) has been advancing across the construction industry, and digitalization of the field—from civil engineering and construction to exterior work—has been attracting attention. Now is an excellent opportunity to rethink traditional methods and take steps toward business improvement using smartphones and the cloud. This article identifies typical challenges in exterior work and explains concretely how the latest technology, LRTK, combined with cloud integration, can solve them. We offer hints on exterior design DX for designers, site supervisors, and construction company owners who are troubled by inefficiencies.

Common problems: information siloing on-site and communication loss

First, let’s organize common problems seen in exterior work. From field surveys through design and construction, the following issues are frequently observed.

• Site information depends on specific personnel: Survey dimensions, photos, and notes tend to be personalized, making it difficult for other team members to grasp the latest information. If a particular person is absent, situations like “I don’t know how far things have progressed” or “Where did they save that photo?” often occur.

• Data tends to be scattered or lost: Survey data may be on paper sketches, drawing files on PCs, and site photos on smartphones or digital cameras—data is stored in disparate places, and the location of the latest data can be unclear. There is also the risk of files being lost or corrupted when transferring via USB drives or email attachments.

• Time lag in information sharing: Sharing on-site information with internal teams or subcontractors often requires sending emails or distributing documents. Even when design changes occur, communicating them to the field can take time, resulting in lagging responses. This can lead to rework or unnecessary waiting during construction, reducing overall project efficiency.

• Image gap with customers: Plans and perspective drawings alone may not fully convey the finished image, and there are cases where customers say “It’s different from what I expected” after construction, resulting in additional work or redo. This represents lost opportunity due to insufficient information transmission during the design proposal stage.

Thus, the combination of site information being siloed and information transmission loss tends to make exterior work inefficient. So how can these challenges be resolved?

“Visible exterior design” opened up by cloud integration

One solution is information sharing and visualization via cloud integration. By aggregating field-acquired data in the cloud and giving all stakeholders real-time access, you can turn personnel-dependent information into shared team assets. With the latest data on the cloud, the site and the office can always confirm the same information, significantly reducing recognition gaps and communication time lags.

Moreover, using the cloud enables workflow reform through visualization. For example, if you upload on-site survey data and photos to the cloud, you can visualize survey points and photo capture locations on a map. You can grasp site conditions from the office as if holding them in your hand, and designers can notice slopes or obstacles that might be overlooked with only 2D plans. Sharing 3D data or AR models on the cloud also allows clients to intuitively “see” the finished image. Because internal and external stakeholders can view the same visual information together, decision-making becomes smoother.

In this way, cloud integration is not just data storage but realizes “site visualization.” Next, let’s look specifically at solutions that use the cloud and smartphones, taking the tool LRTK as an example of supporting exterior design DX.

LRTK strengths: “Measure, capture, show, send” with just one smartphone

The high-precision positioning device for smartphones, the “LRTK Phone.” By simply attaching a pocket-sized antenna-integrated device to an iPhone, centimeter-level accuracy (half-inch accuracy) positioning and 3D scanning become possible. With this compact device and a dedicated app, a wide range of functions from surveying to AR can be easily realized on-site.

At the heart of exterior DX is LRTK. LRTK is a pocket-sized RTK-GNSS receiver that attaches to smartphones (mainly iPhone/iPad), turning a smartphone into a high-precision all-purpose survey instrument with just one device【17行7-15】【17行23-27】. Weighing approximately 150 g and measuring 13 mm (0.51 in) thick, the small device simply attaches to a smartphone using a dedicated case and can measure global coordinates obtained from satellites with centimeter-level accuracy (half-inch accuracy). Tasks that used to require specialized surveying equipment and skilled technicians can be easily and quickly conducted by one person using LRTK.

In short, LRTK’s strength is that a single smartphone can complete “measure, capture, show, send.”

• Measure (high-precision positioning and point cloud measurement): With an LRTK-compatible app, you can record the latitude, longitude, and elevation of the point you want to measure with the push of a button. Tasks that used to require two people with a transit or laser can be completed by one person quickly. There is also a 3D scanning function that uses the iPhone’s LiDAR sensor and camera to capture the entire site’s shape as point cloud data. For example, complex garden elevation differences or the spatial relationships of existing structures can be measured “as a whole” in 3D and used in design.

• Capture (photo shooting with position information): When you take on-site photos with the smartphone camera, the app automatically acquires and records the shooting location coordinates (centimeter-level accuracy / half-inch accuracy) and orientation. It also includes a “subject positioning” function that can calculate the coordinates of a target by aiming a photo from a distance—useful for high branches or distant boundary points that are hard to reach. This allows you to measure high tree branches or far boundary points safely from a distance. Because every photo taken during site surveys is tagged with precise position and orientation data, photo management and survey records are integrated.

• Show (AR proposals and verification): LRTK leverages high-precision coordinates to realize AR (augmented reality) displays that do not drift. If you load prepared exterior 3D models or drawing data into the LRTK app, you can project the design plan on-site simply by pointing your smartphone. No markers or manual alignment are necessary—the 3D model is displayed in the correct position based on absolute coordinates obtained via GNSS. Customers can experience the finished appearance at a realistic scale, and designers and contractors can share the on-site finish image for final adjustments. This AR function, embodying “seeing is believing,” markedly speeds up consensus building.

• Send (cloud data sharing): Any data collected on-site can be uploaded to the cloud and shared on the spot. With one tap from the LRTK app, measurement data and photos can be sent to the dedicated cloud, and office staff can immediately view the latest information in a web browser. There is no need to return to the office to copy files to USB drives or send emails. LRTK cloud data can also be shared via links with clients or subcontractors. Select the data to share, issue a shareable URL, and the recipient can view a password-protected web page without logging in. This makes site⇔office⇔stakeholder data exchange speedy and simple, which is another major advantage.

As described above, LRTK enables “measure, capture, show, send” with a single smartphone. This means information can be circulated in real time led by the field, offering enormous potential to drastically increase productivity in exterior work. In fact, the LRTK Phone is also very affordable compared to conventional equipment, making one-per-person deployment realistic. As a result, the industry has taken note that on-site work productivity can be significantly improved.

Benefits of consolidating photos, drawings, point clouds, and AR in the cloud

Using the cloud service that integrates with the LRTK series (LRTK Cloud), you can consolidate all data acquired on-site in the cloud. The benefits of aggregating multiple information sources—photos, drawings, point clouds, AR—into the cloud for exterior work are immense.

First, about photos. Traditionally, organizing which photos show which locations after shooting with a digital camera or smartphone was troublesome. With LRTK Cloud, uploaded photos are plotted on a map at their shooting locations. Clicking each point allows you to preview the photo along with metadata such as coordinate values, elevation, and shooting direction. This makes it intuitive to see “which photo was taken where,” dramatically reducing the time spent searching for photos later. There is no need to mark shooting locations on paper maps or create photo ledgers after returning to the office. If photos are automatically recorded and synced to the cloud via LRTK’s positioning photo function, both on-site note-taking and office organization work are greatly reduced, and recording errors for shooting locations are eliminated.

Next is management of drawings and design data. On LRTK Cloud, functions are being enhanced to overlay coordinate sets and point cloud data obtained from surveys with CAD drawings and BIM models. For example, if you upload an exterior site plan (DWG file) to the cloud, you can view it overlaid with on-site point clouds or survey points. Comparing a planned fence line on the drawing with the actually scanned terrain data becomes easy. In the future, it will be possible to integrate BIM/CIM models and as-built point clouds in the cloud, seamlessly linking design and construction data. Such features can bridge information gaps between design departments and the field via the cloud.

Handling point cloud data also has big advantages. High-precision point clouds captured by LRTK are saved to the cloud, enabling 3D viewers to display them in a web browser without heavy specialized software on each PC. The team can freely view and measure terrain and structure point cloud models, making “reviewing plans while confirming the site shape together” practicable. Cloud-side functionality for point cloud comparisons and volume calculations means tasks like calculating earthworks volumes and pre/post-construction comparisons can be centralized. For exterior work, estimating fill or excavation volumes becomes efficient if you capture point clouds, as the required volumes can be calculated instantly in the cloud.

Cloud management of AR models should not be overlooked. With LRTK Cloud, you can upload 3D model data in advance and sync it to field devices to enable complex AR placement. For instance, you can send 3D perspective data produced from exterior CAD drawings to a site smartphone via the cloud and project it as full-scale AR in the yard with one click. Managing data in the cloud allows you to ensure “the latest design plan is always available for AR display to anyone.” When sales staff revisit a client’s home, they can pull the latest model updated by the designer from the cloud and make AR proposals, ensuring always up-to-date presentations.

By consolidating photos, drawings, point clouds, and AR through LRTK cloud integration, time spent searching for and converting data is drastically reduced, and all stakeholders can collaborate smoothly on the same platform. A centralized database also becomes an internal knowledge asset, making it easy to search and review similar past projects.

Field-led workflow connecting sales, design, and site in real time

When data is aggregated in the cloud and shared in real time, a workflow that seamlessly connects sales, design, and construction on-site becomes possible. While there may previously have been time lags in interdepartmental information transfer, implementing LRTK produces the following field-led collaborations.

• Early sales stage: Sales staff or site supervisors bring LRTK to site visits and measure key site dimensions and elevation differences on the spot. Because measured data is immediately shared on the cloud, the office design team can start planning the same day. During client interviews, you can project a rough plan in AR—“If we place a wood deck here, this is how it will look” in actual scale. Real-time collaboration between sales and design significantly improves proposal speed and persuasiveness.

• Design and plan creation stage: Designers create CAD drawings and 3D models while referring to cloud-hosted site data (survey points, point clouds, photos). If additional measurements or confirmations are needed, many issues can be resolved via the cloud’s point clouds and photos before revisiting the site. If new measurements are necessary, site staff can take measurements with LRTK and immediately upload them to the cloud for designers to reflect in plans. With bidirectional data exchange between design and site, “additional surveys discovered during design” can be addressed quickly, shortening overall lead times.

• Construction stage: Cloud integration continues to be powerful after construction starts. When site managers record progress with their smartphones, photos are automatically shared to the cloud in chronological order, making internal and client reporting nearly unnecessary. Using LRTK’s coordinate navigation function, you can guide stakes and installations to the exact positions shown on design drawings. For example, if the positions of gate posts or lighting poles are specified in the cloud, on-site workers can mark the exact points to the centimeter level (half-inch accuracy) by following arrow guidance in the app. Even workers without specialized surveying knowledge can reliably reach the designated locations, so anyone can accurately stake and install—a highly practical on-site support feature in times of labor shortages.

• Internal and external communication: With LRTK Cloud, information sharing becomes smooth not only among internal sales, design, and construction teams but also with clients and subcontractors. Using the cloud’s link-sharing function, you can easily let clients view progress data or finished plans online, and instantly share survey data with subcontractors【22行85-94】. Because on-site changes can be immediately updated and disseminated in the cloud, there is no need to rely on follow-up phone calls or faxes. As a result, the whole team stays synchronized with the latest information, forming an ideal field-led workflow for project execution.

Thus, the combination of LRTK and the cloud makes a new way of working possible—“everyone collaborates in real time around field-originated data.” Wasted interruptions waiting for information and rework due to miscommunication decrease, allowing each person more time to focus on their core tasks.

Easier pre-construction visualization and construction-phase record management

LRTK is also highly useful in the pre-construction and construction phases of exterior work, solving traditional problems in two ways: pre-construction visualization and streamlined record management.

First, pre-construction visualization. When proposing an exterior plan to a client, details that were hard to convey with drawings or perspective images alone can be shown on-site using AR. For example, the impact of a new gate or carport on the surrounding scenery is instantly obvious when displayed as AR over the real background. You can check height relationships and sunlight conditions on the spot, enabling immediate, specific client feedback—“Please adjust the height so it doesn’t block that window,” for example. This speeds up consensus building and prevents mismatches like “it’s different from what I expected,” effectively eliminating post-construction complaints and rework. Sharing the finished form in advance with LRTK’s non-drifting AR removes client anxieties and builds trust.

Next, record management during construction. Traditionally, site supervisors recorded progress with photos and later compiled reports, which was time-consuming. After adopting LRTK, construction photos are automatically ledgered in the cloud, allowing on-site recording and office organization to finish in parallel【15行166-174】. For example, if you photograph current conditions before the morning meeting, the location-tagged photo is uploaded to the cloud immediately and stored in the company’s shared folder by date. Because all stakeholders can view it as needed, you can check “How far along is today’s site?” in real time. Photos automatically include coordinates, orientation, and timestamps, so there is no need for later sorting—this semi-automates evidence management. If design changes or additional work arise during construction, sharing that area via a photo note in the cloud notifies everyone instantly. Compared to oral or phone-only communication, this reduces misunderstandings and leaves an audit trail for peace of mind.

Moreover, LRTK Cloud makes it easy to compare past and present data. For instance, you can overlay pre-foundation point cloud data of the ground and post-construction pavement point clouds to check differences in the finished form with the push of a button. Recording each construction stage as 3D data enables future maintenance checks—“Where did the buried piping run?”—to be visualized on-site with AR. In exterior renovations, the amount of investigation required differs greatly depending on whether previous construction records exist; companies using LRTK retain data in the cloud as future assets.

From pre-construction visualization to record management during and after construction, LRTK contributes to efficiency and quality improvement across the entire lifecycle of exterior work.

Case study: What benefits can LRTK bring?

What actual effects can be expected when introducing LRTK? The following is a fictional example comparing before and after the introduction at an exterior construction company, Company A.

A Company A (issues before introduction): A roughly 10-person exterior construction company. Two veteran employees handled surveying with a total station and handed off data in person to the drawing team. From site survey to proposal typically took about two weeks, and customers sometimes said, “We want a quicker estimate.” During construction, site supervisors spent time pasting daily photos into Excel ledgers to report, reducing time available for actual site inspections.

A Company A (changes after LRTK introduction): LRTK units were provided to each employee’s smartphone and site data management was switched to the cloud. The following effects were observed:

• Improved site surveying efficiency: Surveys that previously required two people and half a day could now be completed by a sales representative performing LRTK measurements alone in about 30 minutes during a sales meeting. Coordinate data was immediately shared to the design team via the cloud, so by the time the survey staff returned to the office, design planning had already started. As a result, proposal speed dramatically improved, and the time to first proposal shortened from two weeks to three days.

• Increased order rate: After switching to AR-enabled proposals, clients praised the clarity of the final image and the unique experience. For clients particular about exterior finishes, showing AR design in their own yard sometimes led to immediate decisions. Within six months of introduction, contract rates rose by about 20% year-on-year, contributing to more sales closings.

• Reduced site management labor: Site supervisors could record progress on a tablet and share information with headquarters and clients, drastically reducing time spent on report creation. Time previously used for weekly and monthly report preparation dropped to zero, freeing up more than two hours per day for site rounds and quality checks. Because drawings and instructions are always kept current in the cloud, mistakes stemming from “I wasn’t told” or “I didn’t know” disappeared.

• Broader human resource utilization: LRTK is simple to use, and junior staff acquired the skills quickly. Tasks such as surveying and staking no longer depended on specific veterans, enabling more flexible staffing. Newcomers began conducting site reconnaissance and measurements proactively without waiting for senior guidance, boosting on-site capabilities.

Thus, Company A used LRTK to refresh workflows and achieved “faster, more accurate, and clearer proposals” and “leaner site operations.” This produced a virtuous cycle of increased revenue, higher customer satisfaction, and reduced overtime.

Actual users often say they “can’t return to the old ways,” experiencing the power of smartphone surveying and cloud sharing firsthand. Local governments have also begun adopting iPhone + LRTK systems for disaster recovery field surveys, reporting outcomes such as quickly acquiring accurate point clouds and shortening recovery schedules (for example, adoption in Fukui City). As these cases show, LRTK-driven DX goes beyond mere efficiency gains and leads to new service value and work-style reform.

Conclusion: The future of exterior design is “cloud × smartphone surveying”

The key to DX in exterior design and construction is the fusion of cloud and smartphone surveying. LRTK introduced in this article exemplifies a solution that can fundamentally transform on-site inefficiencies.

Field surveys that used to rely on experience and intuition can now be performed precisely by anyone with a smartphone. We are moving from an era where drawings and photos were managed separately to one where data is centrally managed on the cloud and instantly accessible to the whole team. Without carrying paper materials, you can confirm design plans in the field via AR displayed on your smartphone—such a “new normal” is just around the corner.

The future of exterior design is a world where field and office, contractors and clients are seamlessly connected by digital data. Wasted time from information gaps and communication errors will be eliminated, and all stakeholders will be able to advance projects sharing the same vision. Cloud × smartphone surveying DX not only improves operational efficiency but also delivers the dual value of better customer experience and improved work styles.

The exterior industry is at a turning point. If you feel any inefficiency in your daily work, actively adopt digital technology. Small steps lead to big changes, and the day when “visualized exterior design” becomes the new standard is not far off.
