How Cloud Sharing Will Change Exterior Construction Management: Strengthening Team Coordination with Real-Time Information Sharing

In site management for exterior construction (landscaping/exterior works), information sharing determines the success or failure of a project. It is vital that everyone on the team has timely access to all information, from survey data and design drawings to as-built (the final shape) data and shared understanding with the client (customer). However, traditional methods had many issues with such information sharing. This article organizes the importance of information sharing in exterior construction management and the problems of conventional approaches. It then explains the benefits of real-time information sharing using the cloud and introduces solutions using the latest tools. Please read on for tips that can help strengthen team coordination and improve operational efficiency.

The Importance of Information Sharing in Exterior Construction

Exterior elements such as a house’s garden, fences, and parking area are spaces as important as the main building. Because they affect not only aesthetics but also functionality and safety, accurate construction and unified understanding among stakeholders are indispensable in exterior construction. The key to that is “information sharing.”

Exterior construction generates a wide variety of information, such as pre-construction site survey data, exterior design information created by designers, and as-built data (what was actually constructed) during and after construction. For example, decisions on site must be based on the latest information regarding site elevation differences and boundary lines, specifications of materials to be used, and the client’s desired design. When this information is properly shared, the entire construction team can work with the same goal image, preventing rework and misunderstandings. Sharing the latest information with the client is also essential for building consensus. By sharing the construction progress and the expected finished image with the client, you can avoid disputes such as “this is different from what I was told” and build trust.

In short, information sharing is the key to quality and smooth progress in exterior construction management. Conversely, insufficient information transmission can allow small misalignments to grow into major rework or complaints. Therefore, modern exterior sites need to review how information is shared and adopt more reliable and timely methods.

Conventional Management Methods and Information-Sharing Issues

On exterior construction sites, information has traditionally been managed mainly with paper drawings, verbal instructions, and photo albums of construction photos. These conventional methods have several issues. Below are the main problems.

• Transmission errors and information mismatches: Human errors often occur, such as changes written on drawings by the site supervisor not being communicated to craftsmen, or verbal instructions being misheard by workers. When using paper schedules and drawings, the latest versions are not always fully replaced, and work can proceed based on outdated information.

• Information becoming person-dependent: Information such as survey results or construction cautions tends to exist only in the heads or notebooks of certain experienced workers. If the person in charge is absent, other members cannot respond, creating a risk of information being tied to individuals.

• Inefficient verification work: To check progress and quality, site supervisors traditionally had to visit the site each time and compare photos with drawings. For remote sites, travel time for each visit can prevent timely understanding of progress. Also, if document and photo filing varies by person, it becomes difficult to find needed information later.

• Complexity of photo and document management: Exterior construction requires taking many photos before, during, and after construction, but managing these by printing them into ledgers or saving them on internal servers is cumbersome. Different file naming conventions and storage locations can cause the problem of not being able to quickly access necessary information.

Thus, analog-centered information management lacked real-time capability and tended to be dispersed and person-dependent. As a result, time lags between the field and the office occurred, and small transmission omissions carried the risk of causing rework.

Benefits of Cloud Sharing for Exterior Management

A solution gaining attention to address these challenges is cloud-based information sharing. By centrally managing project information on the cloud, exterior construction management can be transformed. Here are the main benefits.

• Real-time information updates: If the latest survey data, construction photos, or schedule changes obtained on site are uploaded to the cloud on the spot, the whole team can share them immediately. Designers and supervisors located remotely in the office can grasp site conditions in real time, enabling rapid decision-making. Cloud systems allow the site and headquarters to always synchronize the latest information, making it smooth to respond to simultaneous changes that were difficult to manage with paper or Excel.

• Easy comparison with design data: Storing drawings and 3D models on the cloud allows you to compare them with as-built data and photos sent from the site. For example, the office can quickly check whether post-construction heights and positions match the design, enabling early detection of gaps between design and construction. Discrepancies that previously only became apparent after a site report can now be compared and verified on the cloud to prevent rework.

• Smooth coordination between site and office: When information is shared on the cloud, communication between site staff and office personnel becomes much easier. Cloud systems with chat and comment functions enable specific instructions and consultations to be exchanged on the spot while viewing drawings and photos. Nuances difficult to convey via phone or email can be directly annotated on images or drawings in the cloud, eliminating misunderstandings. As a result, team-wide alignment improves, reducing coordination errors and speeding up decision-making.

• Centralized storage and accumulation of information: Storing various documents and photos on the cloud gives everyone involved in the project access to the information they need. Minutes, approval drawings, and construction record photos accumulate in the project folder, making it easier to review later. When the client has inquiries after handover, you can quickly respond by referring to cloud records, which is also useful for after-sales maintenance.

By adopting cloud sharing, exterior construction management evolves into collaboration that overcomes the barriers of time and place. From craftsmen on site to office managers and even clients, everyone can view the same information, dramatically reducing unnecessary work and misunderstandings. The result is shorter construction periods, improved quality, and higher customer satisfaction.

Workflow of Simple Surveying with LRTK and Real-Time Information Sharing

How can cloud sharing be practically used on site? One example is the use of a modern surveying and information-sharing tool called LRTK. LRTK enables seamless surveying, recording, and cloud sharing on exterior sites. Here is the specific workflow.

• 3D point cloud scanning with a smartphone: Surveying that used to require specialized equipment can be easily performed with a smartphone using LRTK. By attaching a small positioning device to the smartphone and walking around the site while aiming the camera, you can perform real-time 3D scanning of the surrounding terrain and structures. Point cloud data acquired with centimeter-level (half-inch accuracy) high-precision positioning (RTK-GNSS) are assigned absolute coordinates, allowing slopes and elevations of the site to be accurately captured on the spot. Even on large residential land development sites, a single person can quickly obtain detailed current-condition data, which is a significant advantage.

• Immediate sharing of acquired data via the cloud: The scanned point cloud data and survey results can be uploaded to the cloud and shared with the team immediately. Once uploaded, the 3D data can be viewed from the office PC or other members’ tablets. Using a cloud viewer, you can overlay and compare them with design drawings and 3D models, and create arbitrary cross-sections as needed to check shapes. For example, whether embankment heights have reached the design levels or whether excavation has been excessive can be checked from headquarters as soon as data are uploaded from the site. In addition, cloud tools can automatically calculate volume differences (soil volume), so volume calculations that used to be manual are completed in an instant.

• AR display of the finished image on site: LRTK also features AR (augmented reality) functions that overlay digital design information onto real-world scenes on a smartphone or tablet screen. By calling up CAD data or 3D models previously uploaded to the cloud and viewing them through the device’s camera, a life-size rendering of the expected finished view or design lines appears in place. Precise alignment allows intuitive on-site confirmation of where buildings or fences will be located and their heights. Since both craftsmen and clients can share the finished image on the spot, this is a powerful way to prevent “differences in perception of the finished result.”

• Recording and sharing site photos: Even in the conventional process of taking site photos, LRTK can tag photos with positioning data (coordinates and orientation) when they are taken. These photos automatically sync to the project on the cloud and are shared in real time with the office and other teams. Since photos are linked with when and where they were taken, they are easy to understand when reviewed later and reduce the effort required to prepare reports.

As described above, using LRTK enables one-stop realization of site grasping, recording, and sharing. The key feature is not merely measuring but immediately sharing and utilizing that data. The system is designed to be usable without special skills, making it easy to introduce even on sites without surveying experts, and dramatically streamlining quality and progress management for exterior construction.

Main Use Cases in the Exterior Field

Cloud-based information sharing and tools like LRTK are powerful in various exterior scenarios. Here are some concrete use cases.

• Residential land development sites: In residential land development, adjusting overall site elevation and managing soil volumes are important. Traditionally, batter boards were set up by section to check heights and survey teams were dispatched to perform volume calculations each time. With cloud-linked tools, the site supervisor can 3D-scan the site immediately after development, check the as-built results, and share the data with headquarters. By instantly comparing the design ground model with the point cloud data, you can check for excesses or shortages in elevation and reduce rework before later inspections. Visualizing block lines and elevation images with AR can also provide intuitive instructions to heavy equipment operators, improving safety.

• Gardens and fence construction: For private garden and fence work, aligning the client’s desired design image with the actual finish is especially important. By confirming the finished image with the client using smartphone AR before construction, you can prevent “this is different from what I expected” in advance. For example, planting arrangements, terrace sizes, or fence heights can be demonstrated on site by overlaying 3D models, allowing sharing of sensory aspects that are hard to convey with words or drawings. If progress photos are shared via the cloud during construction, clients who are remote can receive real-time updates. Even for small garden jobs, these tools lead to closer communication with clients and more trustworthy work.

• Parking lots and exterior works: Information-sharing tools are useful across exterior work such as parking spaces, carport installation, gates, and approaches. Using LRTK for site measurements and layout marking (setting out) is much faster and more accurate than relying solely on tape measures and snap lines. When coordinate data are uploaded to the cloud, designers can immediately check and issue early instructions such as “the parking slope is gentler than planned, so please adjust.” Confirming installation positions of exterior materials with AR during construction prevents repositioning of gateposts and fences and allows one-time correct installation. Retaining photos and as-built data also streamlines creating the construction report delivered to the client after completion.

Thus, from land development to detailed exterior work, cloud-based construction management can be applied widely. Regardless of scale or content, real-time sharing is powerful in every phase of “measuring,” “recording,” and “communicating,” raising productivity and quality in exterior construction.

Use in Consensus Building, Inspections, and Daily Records

Cloud-based information sharing and LRTK offer various added values across the construction process. They are particularly advantageous in client consensus building, responding to inspections, and daily record management as follows.

• Client consensus building: From proposal stage to during construction, photos, drawings, and AR-based finished images shared on the cloud greatly facilitate communication with clients. Even without technical knowledge, clients can grasp concrete images through 3D models and photos, alleviating anxiety and misunderstandings. Real-time progress reporting allows clients to monitor their home’s construction status, leading to increased peace of mind and satisfaction.

• Responding to inspections: Before handover, exterior work may undergo client inspections, internal checks, or municipal completion inspections. In such cases, as-built data and photo records accumulated on the cloud are powerful evidence. For example, if inspection items such as heights or thicknesses can be instantly confirmed from the point cloud data on the cloud, presenting evidence becomes easy. Electronic documents can be searched and referenced on the spot, allowing quick responses to inspection comments. Well-managed information also leaves a good impression on inspectors and demonstrates high reliability.

• Streamlining daily records: The workload for site supervisors creating daily reports and photo ledgers can be reduced by adopting the cloud. Entering daily tasks, progress, and materials used into a cloud form can automatically share information with stakeholders. This removes the need to later transcribe paper reports into Excel or paste photos into documents, making record-keeping smarter. Accumulated daily reports are easy to search, aiding retrospective analysis when problems occur and contributing to internal knowledge accumulation.

With these uses, site management transforms from mere progress recording into a communication tool. To build and maintain trust with internal and external stakeholders while reliably ensuring quality, cloud-based information sharing has become an indispensable approach.

Benefits for Small Sites and Individual Client Projects

Cloud information sharing and new technologies like LRTK bring benefits not only to large projects but also to small sites and private residential exterior works. When manpower and budgets are limited, these productivity-enhancing tools are especially valuable.

• Same-day response capability: Small projects require quick responses to changes. For example, when sudden design changes or additional work requests arise on site, LRTK can perform immediate surveying and calculate new quantities and dimensions. If that data is shared with the office via the cloud, estimate adjustments and design revisions can be completed the same day, minimizing schedule delays. What used to require scheduling a separate surveying team can now be accomplished on the same day by a one-person team.

• Visualizing construction explanations: For individual clients, it can be difficult to explain using technical terms or drawings alone. Using AR and 3D model sharing allows you to explain construction content and the expected finish visually, making client approval easier. For instance, explaining “the concrete will extend to here in the parking area and a flower bed will be located at this position” becomes instantly clear when displayed on a tablet. Even small projects are often once-in-a-lifetime for clients, so digital tools that provide reassurance are highly useful.

• Efficiency through reduced manpower: With a shortage of craftsmen, many exterior contractors must cover many sites with few people. Introducing tools like LRTK that allow one person to complete surveying through recording enables tasks that previously required two to three people to be handled by one. Heavy surveying equipment no longer needs to be carried, and high-precision measurements can be performed with simple operations, maintaining site management quality even without veterans. Cloud-based information sharing also reduces unnecessary site trips and meetings, allowing personnel to be allocated to other tasks. This effective use of limited resources and nimble responsiveness highlights the value of digital tool adoption.

Small sites, in particular, can benefit significantly from cloud sharing and simple surveying tools. Even with minimal staff, leveraging digital technology makes it possible to deliver quality and services that can compete with larger firms.
