Exterior Design DX: Improve Work Efficiency with LRTK Cloud Integration

Introduction: Do you feel inefficiency in exterior work?

Do you ever feel things are somehow inefficient on-site in exterior (landscaping) design or construction management? For example, during on-site surveys you measure dimensions manually with tape measures and levels, record them on paper drawings or notes... Back in the office you re-enter everything into CAD software, sometimes spending time deciphering notes or realizing you missed measurements. During pre-construction meetings, it’s often difficult to convey the final image to clients using only plan drawings or catalog photos, and mismatched expectations can lead to rework. Site progress reporting can also be time-consuming, with supervisors taking photos, emailing them, and compiling documents.

In recent years, DX (digital transformation) has progressed across the construction industry, and the digitization of the field—from civil engineering and construction to exterior work—has attracted attention. Now is a great opportunity to review traditional practices and step toward workflow improvements that leverage smartphones and the cloud. This article identifies typical challenges in exterior work and explains concretely how the latest technology “LRTK” and its cloud integration can solve them. We offer hints for exterior design DX to designers, site supervisors, and builders struggling with inefficiencies.

Common issues: information hoarding on individuals and communication loss

First, let’s organize common problems in exterior work. In the process from site survey to design and construction, you often see the following issues:

• Site information relies on individuals: Survey measurements, photos, and notes tend to become person-dependent, making it hard for other team members to know the latest information. If a particular person is absent, situations like “how far has this progressed?” or “where did that photo get saved?” frequently arise.

• Data easily becomes scattered or lost: Survey sketches on paper, drawing files on PCs, site photos on smartphones or cameras—information is stored in many places, and it can become unclear which is the latest. There is also a risk of files being lost or corrupted when exchanged via USB drives or email attachments.

• Time lag in information sharing: Sharing on-site information with in-house teams or subcontractors often requires sending emails or distributing documents. Even when design changes occur, conveying them to the site can take time, causing delayed responses. As a result, rework or idle waiting time can occur during construction, reducing overall project efficiency.

• Image gap with clients: Plans and perspective drawings alone cannot fully convey the completed image, and clients may say after construction, “This isn’t what I expected,” leading to additional work or redoing. This is a loss of opportunity due to insufficient communication during design proposals.

In this way, the combination of information hoarding at the site and communication loss tends to make exterior work inefficient. So how can we solve these problems?

“Visible exterior design” enabled by cloud integration

One solution is information sharing and visualization through cloud integration. By aggregating data collected on-site in the cloud and giving all stakeholders real-time access, you can turn information that was person-dependent into a shared team asset. With the latest data on the cloud, the site and the office can always confirm the same information, greatly reducing recognition gaps and communication delays.

Furthermore, using the cloud enables operational reform through visualization. For example, if you upload survey data and photos to the cloud, you can visualize survey points and photo locations on a map. Designers in the office can grasp site conditions as if holding them in their hands and may notice slopes or obstacles that were overlooked on a plan. By sharing 3D data or AR models in the cloud, you can present an intuitive and visible completed image to clients. Because internal and external stakeholders can review the same visual information together, decision-making becomes smoother.

Thus, cloud integration is not merely data storage but realizes “site visualization.” Next, let’s look at a concrete solution that leverages the cloud and smartphones using the tool LRTK.

LRTK strengths: “Measure, Capture, Show, Send” with just one smartphone

“LRTK Phone” is a high-precision positioning device that attaches to a smartphone. Simply attach the pocket-sized, antenna-integrated device to an iPhone and you can achieve centimeter-level positioning and 3D scanning. With this compact device and its dedicated app, you can easily perform a wide range of functions on-site from surveying to AR.

A key to 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 surveying instrument with just one device【17行7-15】【17行23-27】. The small device weighs about 150 g and is 13 mm thick; attaching it to a smartphone with a dedicated case allows measurement of global coordinates obtained from satellites with centimeter-level accuracy. Tasks that previously required specialized surveying instruments and experienced technicians can be carried out quickly and easily by one person using LRTK.

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

• Measure (high-precision positioning and point cloud measurement): With an LRTK-compatible app, you can record the latitude, longitude, and height of a desired point with the press of a button. Surveys that once required two people with a transit or laser can be done quickly by one person. There is also a 3D scanning function using the iPhone’s built-in LiDAR sensor and camera, enabling acquisition of the entire site’s shape as point cloud data. For example, you can measure complex garden elevation differences and the relative positions of existing structures in 3D and use them in design.

• Capture (geotagged photo capture): When you take site photos with the smartphone camera, the shooting coordinates (to centimeter precision) and orientation are recorded automatically. It also includes a “target positioning” function that can calculate the coordinates of a subject by aiming from a distance, allowing measurement of objects that are high or out of reach. This makes it possible to measure high tree branches or distant boundary points safely from a distance. Because every photo taken during site surveys is tagged with accurate position and orientation data, photo management and survey records can be unified.

• Show (AR proposals and verification): LRTK uses the acquired high-precision coordinates to enable AR displays that don’t drift. If you load prepared exterior 3D models or drawing data into the LRTK app, you can project design plans on-site by simply holding up your smartphone. No markers or manual alignment are required—the 3D model is placed accurately based on absolute coordinates from GNSS. Clients can experience the completed appearance at real scale, and designers and contractors can share the on-site final image for last-minute adjustments. The AR function, which proves that “seeing is believing,” dramatically speeds up consensus building.

• Send (cloud data sharing): All data collected on-site can be uploaded to the cloud and shared on the spot. From the LRTK app you can send measurement data and photos to the dedicated cloud with one tap, and office staff can immediately check the latest information in a web browser. There’s no need to return to the office to copy files to a USB drive or send emails. LRTK cloud data can also be shared via links with clients and subcontractors. By selecting data and issuing a shareable URL, recipients can view a password-protected web page without logging in. This quick and simple data exchange between the site, the office, and stakeholders is a major advantage.

As described above, LRTK enables you to complete “measure, capture, show, send” with just a smartphone. This means information can be circulated in real time, led by the site, and has great potential to dramatically improve productivity in exterior work. In fact, LRTK Phone is relatively affordable compared to traditional instruments, making one-per-person deployment realistic. As a result, the industry is taking note that on-site productivity could greatly increase.

Benefits of centralized cloud management for photos, drawings, point clouds, and AR

By using the cloud service that integrates with the LRTK series (LRTK Cloud), you can centrally manage all data collected on-site in the cloud. In exterior work, aggregating multiple information sources—photos, drawings, point clouds, AR—in the cloud brings enormous benefits.

First, about photos. Traditionally, organizing which photo corresponds to which location after shooting with a camera or smartphone was troublesome. With LRTK Cloud, uploaded photos are plotted on a map at their shooting locations. Clicking each point lets you preview the photo along with metadata such as coordinates, elevation, and shooting direction. This makes it intuitive to grasp “which photo was taken where,” dramatically reducing the time spent searching for photos later. There is no need to write shooting locations on paper maps or create photo ledgers after returning to the office. With LRTK’s geotagged photo function and cloud sync, on-site note-taking and office sorting are greatly shortened, and recording mistakes about shooting locations are eliminated.

Next, management of drawings and design data. LRTK Cloud offers growing features to overlay survey coordinate sets or point clouds with CAD drawings and BIM models. For example, if you upload a plan (DWG) of an exterior to the cloud, you can view it overlaid with on-site point clouds or survey points. Comparing a planned fence line on a drawing with scanned terrain data is easy. In the future, it will be possible to display BIM/CIM models integrated with current point clouds on the cloud, seamlessly linking design and construction data. Such capabilities help close the information gap between design departments and the site.

Handling of point cloud data also brings major benefits. High-precision point clouds captured by LRTK are stored directly in the cloud, so you don’t need heavy dedicated software on each PC—you can view them in a 3D viewer via a web browser. Team members can freely view and measure terrain and structure point cloud models, so “examining the site’s shape together while considering plans” becomes realistic. Cloud-side tools can handle point cloud comparisons and volume calculations, centralizing tasks like calculating earthwork volumes or comparing pre- and post-construction results. For estimating fill or excavation volumes in exterior work, just having the point cloud allows you to instantly compute required volumes in the cloud, improving efficiency.

Cloud management of AR models is also noteworthy. With LRTK Cloud you can upload 3D model data in advance and sync it to field devices so complex AR placements are possible. For instance, you can send 3D perspective data derived from exterior CAD drawings to on-site smartphones via the cloud and project them at full scale in the yard with one click. Managing data in the cloud ensures that “the latest design plan can be AR-displayed anytime by anyone.” When a salesperson revisits a client, they can pull the latest model updated by the designer from the cloud and present it in AR, which is a great advantage.

By centralizing 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. The centralized database also becomes an organizational knowledge asset, making it easy to search and review past projects with similar conditions.

A site-driven workflow connecting sales, design, and field in real time

When data is aggregated in the cloud and shared in real time, a workflow that seamlessly connects sales, design, and construction emerges. Traditionally there might have been time lags in interdepartmental information transfer, but with LRTK, the following site-driven collaborations can be realized.

• Early sales stage: Salespeople or site supervisors can bring LRTK during site visits to measure key dimensions and elevation differences on the spot. The measured data is shared to the cloud immediately, allowing the office design team to start planning the same day. During client interviews, you can project a rough plan in AR and show, for example, “If you place a wood deck here, this is how it will look at this size” at real scale. Real-time collaboration between sales and design dramatically improves proposal speed and persuasiveness.

• Design and plan creation stage: Designers create CAD drawings and 3D models while referring to on-cloud site data (survey points, point clouds, photos). If they find additional points to measure or locations to check, they can often resolve them using point clouds or photos on the cloud before returning to the site. If new measurements are truly needed, they can request site staff to measure with LRTK and the data will immediately upload to the cloud and reflect in the design. Because design and site can exchange data bidirectionally, you can quickly address “additional surveys identified during design,” shortening overall lead times.

• Construction stage: Cloud integration is also powerful after construction begins. When supervisors take photos to record progress, the photos are automatically shared to the cloud in chronological order, greatly reducing the need to prepare reporting materials for the office or clients. LRTK’s coordinate navigation function can guide placement and staking with high accuracy according to the design drawings. For example, if you specify installation locations for gate posts or light poles on the cloud, workers can follow the in-app arrow guides and mark points to centimeter precision. Even workers without surveying knowledge can reach exact positions without hesitation, so anyone can accurately stake and install. This is a very practical on-site support measure amid labor shortages.

• Internal and external communication: By introducing LRTK Cloud, not only do internal sales, design, and construction teams benefit, but owners and subcontractors can also share information smoothly. With the cloud’s link-sharing function, you can show clients progress data or final drawings online and instantly share survey data with subcontractors【22行85-94】. Changes occurring on-site can be immediately updated and communicated on the cloud, removing the need to rely on follow-up phone calls or faxes. As a result, the whole team stays synchronized with the latest information and an ideal site-driven project workflow takes shape.

In this way, the combination of LRTK and the cloud enables a new working style where everyone collaborates in real time around site-originated data. Wasteful interruptions waiting for information and rework from communication errors decrease, allowing each person to spend more time on their core duties.

Easier pre-construction visualization and construction-phase record management

LRTK is very useful in both the pre-construction and construction phases of exterior work. It addresses traditional issues in two ways: pre-construction visualization and streamlined record management.

First, regarding pre-construction visualization. When proposing exterior plans to clients, details that were hard to convey with drawings or perspective images can be shown on-site with AR. For example, how a new gate or carport affects the surrounding scenery is immediately clear in an AR overlay on the actual background. You can also check height relationships and sunlight conditions on the spot, allowing you to get concrete feedback from clients like “Please adjust the height so it doesn’t block that window.” This rapid consensus building prevents mismatches like “it’s different from what I imagined” later, virtually eliminating complaints or rework after construction. Sharing the final look in advance with drift-free AR using LRTK is itself a process that removes pre-construction anxiety and builds trust.

Next, construction-phase record management. Traditionally, supervisors recorded progress with photos and later compiled them into reports, which was time-consuming. After introducing LRTK, construction photos are automatically ledgered in the cloud, so on-site recording and office organization complete in parallel【15行166-174】. For example, if you photograph the current state of a construction area before morning assembly, the geotagged photo is uploaded to the cloud immediately and stored in a shared folder by date. Everyone involved can view it at any time, so checking “how far did today’s work progress?” is done in real time. Photos automatically include coordinates, orientation, and timestamp, eliminating the need for later organization and making evidence management semi-automated. If a design change or additional work occurs during construction, sharing that location via a photo memo on the cloud communicates it to all stakeholders immediately. Compared to oral or phone communication, misunderstandings are reduced and a log is kept for reassurance.

Additionally, LRTK Cloud makes past-vs.-present data comparison easy. For example, you can overlay pre-foundation point clouds with completed pavement point clouds to check differences in as-built conditions with a single click. If each construction phase is recorded in 3D data, future maintenance can visually confirm things like “where were the buried pipes routed?” using AR on-site. For exterior remodeling projects, having past construction records significantly reduces the time needed for investigation. Companies using LRTK become custodians of data in the cloud, turning it into a future asset.

Thus, from pre-construction visualization through construction and completion record management, LRTK contributes to efficiency and quality improvement across the entire lifecycle of exterior work.

Case study: What results can be gained by introducing LRTK?

What effects can you expect after introducing LRTK? Below is a hypothetical example comparing before and after adoption at an exterior construction company, Company A.

Company A (issues before adoption): A 10-person exterior construction company. Surveying was handled by two veteran employees using total stations, and data was handed to the drawing person. From site survey to proposal typically took about two weeks, and clients sometimes asked, “Can we get an estimate sooner?” During construction, supervisors were busy pasting daily photos into Excel ledgers for reporting, reducing time for actual site inspections.

Company A (changes after LRTK adoption): They deployed one LRTK per employee smartphone and switched to cloud management of site data. They experienced the following effects:

• Improved site survey and investigation efficiency: What used to take two people half a day could now be completed by a sales rep in about 30 minutes during a client visit using LRTK. Coordinate data was shared to the design office via the cloud immediately, so design planning started by the time the surveyor returned to the office. As a result, the proposal lead time dramatically improved, shortening the time to first proposal from two weeks to three days.

• Increased order conversion rate: By switching to AR-enabled proposals, clients responded, “The post-construction image became clear” and “We experienced something unique.” Especially with clients who cared strongly about exterior design, showing AR designs in their own yard led to immediate decisions. Six months after introduction, contract rate increased by about 20% year-on-year, contributing to more sales.

• Reduced workload for site management: Supervisors could record progress with a tablet and share information with head office and clients, drastically reducing time spent preparing reports. Time spent on weekly and monthly reports dropped to zero, freeing up more than two hours per day for site inspections and quality checks. Keeping drawings and instructions always up-to-date in the cloud eliminated mistakes from “I wasn’t told” or “I didn’t know.”

• Broader use of human resources: LRTK is simple to use and young staff learned it quickly. This allowed tasks like surveying and staking to be handled by anyone rather than relying on certain veterans, increasing staffing flexibility. New hires could independently do site reconnaissance and measurements without waiting for senior guidance, raising overall field capability.

As shown above, Company A refreshed its workflow after introducing LRTK and achieved faster, more accurate, and clearer proposals and leaner site operations. This resulted in increased revenue, higher customer satisfaction, and reduced overtime—a virtuous cycle. Real users also report “we can’t go back to the old ways,” and the power of smartphone surveying plus cloud sharing is being felt. Local governments have begun adopting iPhone + LRTK systems for disaster recovery site surveys, reporting shortened restoration schedules by quickly obtaining accurate point clouds (e.g., adoption in Fukui City). These examples demonstrate that LRTK-driven DX goes beyond mere efficiency gains and leads to new service value and workstyle reforms.

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

The key to DX in exterior design and construction is the integration of cloud and smartphone surveying. LRTK, introduced in this article, is a representative solution that demonstrates the potential to fundamentally change inefficiencies on-site.

Site surveys that once relied on experience and intuition can now be performed precisely by anyone with a smartphone. We are moving from an era of scattered drawings and photos to one where everything is centrally managed in the cloud and accessible to the whole team. Without carrying paper materials, you can check design plans via AR on a smartphone screen on-site—such “the new normal” is approaching.

The future of exterior design is a world where site and office, contractors and clients are seamlessly connected by digital data. Waste from information gaps and communication errors will be eliminated, and all stakeholders can advance projects sharing the same vision. Cloud × smartphone surveying DX not only increases operational efficiency but also brings the dual value of better customer experiences and improved workstyles.

The exterior industry is at a turning point. If you feel even a little inefficiency in daily operations, actively try adopting digital technology. Small steps can lead to big change, and the day when “visible exterior design” becomes the new standard may not be far off.

Appendix: Getting started with site surveys and AR exterior proposals using LRTK

Finally, for those thinking “I might want to try it,” here are first steps for using LRTK. The adoption barrier for LRTK is not high. Attach the dedicated device to a supported iPhone and install the LRTK app from the App Store—then you’re ready. With an initial explanation, almost anyone can learn the basic operation in a few minutes.

Start with simple surveys: First, try single-point positioning and photo surveying at an accessible site. For example, measure your company parking lot with LRTK or display a planting plan in AR. You can see immediate benefits in small everyday cases. You will likely be surprised at the precision and ease compared to traditional methods.

Try AR design proposals: Next, incorporate AR proposals into an ongoing exterior project. If you have perspective images, convert them to a supported format and load them into the LRTK app to enable on-site AR display. Start simply—show a client “how this gatepost looks in front of the entrance” via their smartphone. Seeing a 3D model appear at actual scale will positively change client reactions.

Smartphone surveying and AR proposals with LRTK may be surprising at first, but as you use them more you’ll wonder why you didn’t start sooner. As a first step in exterior design DX, leverage LRTK’s cloud integration solution to achieve immediate work efficiency gains and added value. New discoveries and excitement will surely emerge at your site.
