“Daewoo E&C leverages Meissa to capture detailed site records and streamline field operations.”
Multi-family residential construction sites involve numerous processes taking place simultaneously, with multiple subcontractors working in parallel. Given the complexity and constant changes on-site, intuitive visual data and structured records are essential for making accurate, timely decisions.
This is why Daewoo E&C adopted the Meissa Platform. By chronologically documenting site progress and integrating multi-channel data in one view, Meissa enhances data sharing and streamlines operations.

From Site Monitoring to Budget Verification
Q. Could you briefly introduce your project site?
💬 Mr. Yoon, General Affairs Lead
Hello, I’m Yoon Young-gyun, team leader of the General Affairs Department for the Yeongtong Prugio Phase 1 residential complex.
Alongside me are Lee Jae-young, the section chief for Zone 1; Lee Jin-bae, in charge of structural work; and senior managers Ahn Ji-hoon and Jang Young-jae, responsible for the commercial area and selected buildings.
Our site broke ground in July 2022 and reached completion at the end of March this year. Meissa was the first drone platform we used on this project. We were already familiar with drone photography, such as wide-angle site images, so the adoption itself didn’t pose a major challenge. However, we did initially wonder how useful features like “automated earthwork volume calculation” and “structural progress monitoring” would be in actual site operations.
After using the platform ourselves, we found many functions to be genuinely applicable to real-world tasks—especially during the earthwork phase. Meissa helped us track earthwork progress based on topographic survey data, generate internal and external reports, and calculate budget quantities with greater accuracy.
💬 Mr. Kim, Section Chief
Hello, I’m Kim Ki-jung, the site manager overseeing Zone 2 of the project. We began using Meissa almost simultaneously with the construction start of Phase 2. While I’ve now tried out most of Meissa’s features, in the early stages I focused particularly on its applicability in conjunction with BIM data, since this site was operated as a BIM sampling site.
Personally, I’ve long been using drone data in various ways on-site and have experience with other platforms as well, so the adoption process posed no significant difficulties. Compared to other platforms, Meissa felt lighter to use, and especially more convenient when it came to customer support—whether resolving issues or inquiring about specific features.
Because the Meissa team quickly responded to field needs and implemented necessary functions, we were able to utilize the platform effectively through to project completion.
Q. Has anything become more convenient after adopting Meissa?
💬 Mr. Yoon Young-gyun
From the perspective of the general affairs team, the biggest convenience has been the ability to make budget-related decisions more quickly and accurately.
One particular case stands out. During the process of removing soil from the site, we had both high-quality and poor-quality soil, and we needed to clearly distinguish between them to request appropriate processing budgets from headquarters. However, the initial draft of the geotechnical survey report was significantly different from the actual conditions on-site.
We used Meissa to pinpoint the exact locations for soil sampling and conducted material tests at those specific spots. As a result, we found that soil which had appeared acceptable in the report was in fact of poor quality.
We were able to clearly present this evidence: “This is the exact area on the site where the sample was taken. While the soil may look fine on the surface, the test results show it is not suitable.” This allowed us to justify our budget request with concrete, visual proof.
💬 Mr. Lee, Construction Lead
From the construction team’s perspective, the biggest advantage was being able to accurately grasp the current conditions on-site. Our work moves in real time, while drawings remain static. There are many things you can’t catch with drawings alone, but Meissa made those aspects visible. For example, site cleanup details or slight modifications made during construction. We found it particularly useful for planning material yard divisions or designating storage areas. It was also helpful when checking whether construction was progressing in line with updated drawings.
💬 Mr. Ahn, Senior Manager
In my case, it was especially helpful for managing time. On the drawings, we mark out the areas to be concreted, but in reality, the pour lines often don’t match exactly. In the past, to check how much wider or narrower the actual pour was, I had to go out to the field, measure manually with a tape, and calculate the area myself.
After adopting Meissa, that process changed. I no longer had to go out, measure, come back, and organize everything again. It didn’t just feel more convenient—it actually sped up the workflow.
To be honest, I was a bit skeptical at first. I wasn’t sure the measurements would be accurate. So initially, I double-checked by measuring distances and calculating areas myself. But when I compared the numbers, Meissa’s results matched mine. After that, I gradually built trust in the platform and was able to make full use of it through to completion.
Simple Meeting Prep, Instant Progress Sharing
Q. Beyond convenience, has Meissa simplified any part of your day-to-day workflow?
💬 Mr. Kim, Section Chief
Absolutely—meeting preparation, for one. To prepare for meetings, we used to spend a lot of time opening CAD or Revit files, which required specialized software and significant conversion time due to the file size and complexity. With Meissa, those data files can be uploaded in advance, which has greatly simplified the document preparation process.
Now, I just upload the necessary data to Meissa from the office and bring a single laptop into the meeting room. We overlay orthophotos and drawings to discuss hazard zones or equipment placement, and we can display 3D point clouds alongside BIM data to compare the model with actual site conditions in real time. Previously, we had to switch between separate 3D models and photo documentation—now everything is viewable in a single screen, which makes it much easier to understand.
The same goes for photo materials. Since we deal with various types—overhead images, modeling visuals, and site photos—it used to be confusing for people who weren’t familiar with them. But with Meissa, everything is presented based on actual site locations, so it's easy to say, "This is our office, and this is Building X." It’s made things much easier, both for those preparing the meetings and for those participating in them.
💬 Mr. Lee, Construction Lead
To echo that point, Meissa is incredibly useful as a visualization tool. One of its biggest advantages is accessibility—anyone can view the site status in real time as long as they have a computer and an internet connection. Even in meeting rooms at the infrastructure work zone, having just a tablet is enough to pull up the site status and review it together with relevant personnel.
💬 Mr. Yoon, General Affairs Lead
Previously, we had to bring printed drawings just to plan out the material yard. Now, we can simply open Meissa during the meeting and say, “This area is for Company A, and that area is for Company B,” all on-screen.
If someone requests a certain amount of space, we can calculate it immediately. In the past, we had to sketch the area manually on a printout and then get individual approvals one by one—“Do you agree with this? Do you agree with that?” Now it’s all done on one screen, and everyone understands the layout faster, making the entire process much more efficient.
Managing the Site Through Records, Not Just Memory
Q. Has having a recorded platform history helped you in any real situations?
💬 Mr. Lee, Structural Work
There was a case where we had to re-excavate an area where electrical cables for the tower crane had already been buried. We couldn’t risk damaging the cables with a backhoe, so we weren’t sure how to proceed. Then I remembered we had done a drone flight around that time and checked Meissa.
Fortunately, I was able to determine the approximate location of the buried cables and safely carry out the next phase of construction. That experience really stood out to me.
💬 Mr. Yoon, General Affairs Lead
We held regular meetings—once or twice a month—with the team responsible for infrastructure work around the residential complex. Those meetings often involved coordinating work boundaries. I would take a tablet with Meissa loaded and use it to check for site interference or to confirm which team was in charge of which zone at a specific time.
Because past data remains on the platform, it helped prevent long debates or misunderstandings.Another memorable case involved an issue with quantities at the start of construction. There was a discrepancy between the ground level stated in the geotechnical report and the actual level at the time of groundbreaking. We needed to recalculate the budget, and it just so happened that orthophotos from both July and September were available in Meissa.
Since Meissa stores orthophotos tied to specific dates, we could compare the ground elevations between those two points in time and quickly identify the differences.
Q. We noticed that Phase 2 has maintained detailed records for each construction stage. Is there a particular reason you’ve been so diligent about data retention?
💬 Mr. Kim, Section Chief
As construction progresses, both the person in charge and I tend to forget things unless they were major issues. That’s why I believe keeping a record is extremely important.
Personally, I’ve made a habit of saving data from the time of project completion onward, hoping it could be used later for minor or major repairs. The data I’ve organized so far amounts to about 2 terabytes. The problem, however, is that I’m the only one who has access to it. If I or any other key personnel were to leave the company, that data would essentially become unrecoverable.
That’s why I see value in a cloud-based platform like Meissa. I want to ensure that all critical data is systematically stored in one place where it remains accessible to everyone who needs it.
Even if the data itself isn’t particularly significant, just being able to verify what photos were taken on which date and what issues occurred at the time can serve as crucial evidence in the event of defects or disputes later on.
There have been cases where files were deleted under the assumption that “we won’t need them after completion,” only to realize they were needed at a critical moment. Because of experiences like that, I now make a conscious effort to consistently store and retain all available data whenever possible.
Daewoo E&C and Meissa: Shaping the Future of Smart Construction
Q. Do you see yourselves continuing to use Meissa going forward?
💬 Mr. Lee, Construction Lead
This was my first time using a drone-based platform, and after experiencing it, I genuinely want to keep using it. What I particularly like about Meissa is that it reflects the fundamental nature of construction very well.
That’s an important point—because construction sites can’t stop. Every second counts, and work in the field keeps moving, so it's hard to handle everything in real time from the office. You can’t pause the site just to take the next step. In the end, what matters most is what’s been recorded.
From that perspective, a platform like Meissa, which allows you to chronologically capture the flow of the site, holds significant value. If it offered even more photo-based organization features, that would make it even better.
💬 Mr. Kim, Section Chief
In the past, whenever an issue came up, we used to mark everything directly on paper drawings. But if the person responsible happened to be off that day, it was difficult to locate the materials.
Now, for anything that needs to be shared, I upload it to Meissa or OneDrive and work collaboratively so the task can move forward even if one person is unavailable.That’s why I also encourage junior engineers and assistant managers: “I’ve uploaded these materials to Meissa—go ahead and upload yours too. That way, you can conduct meetings more effectively.”
Doing this clearly reduces unnecessary tasks. It also makes preparing materials easier. Platforms like Meissa are essential—not just for visualization, but for ensuring continuity in our work.
