“With Meissa, Lotte E&C coordinates today's complex workflows and previews tomorrow's completed complexes.”
On large-scale, complex residential sites with significant elevation differences, accurate tracking and workflow coordination determine project success. Lotte E&C adopted Meissa to overcome the limitations of 2D drawings, streamline subcontractor cost settlements, and efficiently manage everything from safety to site control.
Check out our interview from Lotte E&C's Incheon Hyoseong District Residential 4BL site to see how Meissa became a vital tool for team communication and site management.
Seamless Communication on a Unified Platform
Q. Could you briefly introduce your site?
💬 Park Gyu-young, Site Manager
"Hello, I am Park Gyu-young, the Site Manager for the Incheon Hyoseong District Residential 4BL project. We began in September 2024 and are now entering the final stages of construction.
When I took over this site in 2024, my biggest challenge was finding a smart way to monitor a complex project at a glance. After hearing about the success of using Meissa at our Cheonan site, I worked with our R&D institute to implement it here.
We started using the platform during the initial excavation phase. It was incredibly useful for pinpointing earth retention and earth anchor locations by interacting with the 3D models. Experiencing that practical value early on is why we still rely heavily on Meissa today for site monitoring and subcontractor coordination as we wrap up construction."
Q. It is impressive that the entire site team, not just a few managers, uses Meissa. How did that start?
💬 Mr. Park Gyu-young (Site Manager)
To be honest, I had some reservations at first. While the technology is great, I worried that exposing every corner of the site might feel like micromanagement or put pressure on the staff.
However, we pushed forward because I knew the benefits of having clear records would far outweigh those concerns. When issues like cost settlements arise with subcontractors, our team can confidently and smoothly handle the process backed by objective data.
Initially, I had to encourage its use, but now the team takes the initiative. When I log into the platform, I see they are actively applying Meissa to various tasks completely on their own.
Resolving Current Workflows, Shaping the Future
Q. How are you using Meissa for workflow coordination and task delegation on such a complex, multi-level site?
💬 Mr. Kim Tae-hoon (Construction Team)Because our site has significant elevation differences, work sequences can easily get tangled. It used to be a struggle to explain this verbally, but now we pull up Meissa on a tablet during subcontractor meetings.
We coordinate intuitively by looking at the screen: 'This is the pump car area, and that’s the crane radius, so let’s split the work into AM and PM to avoid clashes,' or 'Waterproofing starts here, so please clear the materials.' We even measure pouring distances directly on the platform to check equipment reach before finalizing our plans.
Q. It seems you have overlaid various drawings on Meissa. How exactly were these blueprints utilized in practice?
💬 Mr. Park Gyu-young (Site Manager)
The design overlay feature is exceptionally useful. We relied on it heavily to verify the positioning of temporary structures, underground facilities, precast concrete (PC), and basement columns.
It was particularly valuable during PHC piling work, as it displays exact pile locations. If we notice any deviation on the screen, we can immediately call the subcontractor to address the issue. Doing this manually on-site is incredibly labor-intensive, but being able to check it instantly from the office has been a massive help for construction management.
💬 Mr. Park Gyu-young (Site Manager)
Physical mock-ups are usually bulky and take up too much space in a temporary site office. However, digitizing the mock-up into a 3D model and uploading it to the platform has made our weekly meetings incredibly convenient.
We use Meissa's site mapping to track the 'present' progress, while referencing the 3D model to visualize the 'future' outcome. It allows us to hold proactive planning meetings by rotating the complex in real-time to answer questions like, 'How is the layout of this road designed?' or 'What is the planned elevation for the landscaping stones and internal site differences?'—details that are often hard to grasp from 2D flat drawings alone.
Initially, we uploaded it to keep a solid record in case of future civil complaints regarding discrepancies from the model house post-completion. But in practice, the greatest advantage is being able to see both the beginning and the end of the project within a single platform. Honestly, I didn't expect it to be this versatile when we first started, but it has proven to be exceptionally useful.
Proving Site Data with Numbers: Beyond the Blueprints
Q. Did you also use Meissa to calculate material quantities during earthworks or structural framework construction?
💬 Mr. Park Gyu-young (Site Manager)
Yes, we utilized it for interim cost settlements with our subcontractors. Knowing the total volume isn't enough; we need to analyze the data by specific soil properties.
By capturing drone data every time the soil strata changed, we obtained highly accurate values and finalized our settlements based on those figures. Having this clear, objective evidence pleased the headquarters team as well. It made me realize that this platform could significantly reduce chronic settlement disputes.
💬 Mr. Kim Tae-hoon (Construction Team)
Its usability goes beyond earthworks; it’s highly effective for foundation concrete pouring as well. Excavations never turn out as perfectly as the drawings suggest; over-excavation is inevitable. In the past, we had to either redraw the plans to account for this or add a premium to calculate the correct quantities.
With Meissa, even for irregular surface areas like leveling concrete or weight concrete, we can simply use the area measurement tool to get an immediate estimate when we are in a rush. It is a massive help for grasping the actual required materials. When we later compared our estimates to the actual poured volume, the calculated margin of error was remarkably precise.
Lotte E&C and Meissa: Shaping the Future of Smart Construction
Q. Do you plan to continue using Meissa on future projects?
💬 Mr. Park Gyu-young (Site Manager)
Whenever external inspectors or VIPs visit, I always bring up the Meissa platform to guide the discussion. We use it extensively in meetings to overlay drawings or proactively review 3D models for site elevations, roads, and landscaping that are hard to grasp in 2D. It has also been a massive help in reducing settlement disputes.
Honestly, I didn’t expect a single platform to cover this much ground. I am very grateful for how it enables transparent site management. I heard the 3D viewer is getting an update soon, and I look forward to utilizing it even more effectively on our next project.
