Kajima Building & Design Group (KBDG), headquartered in Atlanta, GA, was selected as the general contractor to build a Research and Development Center at a tire manufacturing facility. The facility consisted of laboratory and office spaces. KBDG managed the design and coordination process by using 3D BIM tools, an existing drone program for exterior image capture, and 360º cameras for indoor reality capture.
With Reconstruct KBDG was able to :
- Complete the project 4 weeks earlier.
- Have zero subcontractor change orders.
- Spend 50% less time going back and forth for off-site execs.
-
Have a 30%
"Reconstruct was very easy to use. I could train a superintendent on how to use the Reporter app in 30 minutes."

The Problem
The project team was looking for an integrated solution that provided enhanced outdoor and indoor progress monitoring against their planned model and schedule (4D BIM). KBDG wanted a solution that could support the building of their 4D BIM model by linking BIM elements to schedule activities, as well as a system that could generate 3D point clouds from both their drone images and 360° video capture. In addition, KBDG sought a solution that could be used for the entire lifecycle of the project, starting from site works throughout commissioning. They were looking for a tool that not only displays visual progress but also provides markup and measurement capability on both the model and the 360º pictures.
The Solution
Initially, KBDG conducted reality capture with drones every two weeks during the core and shell phases. Then, during the interior build-out phase, the project performed weekly 360° video walks to capture interior progress. They chose Reconstruct as their one-stop shop to connect their model, schedule, and the generated 3D point clouds. Leveraging Reconstruct’s Reporter App, the on-site team did daily schedule updates. For any delayed schedule activities, root cause data was captured and analyzed. The platform provided reality timelines and generated all contextually accurate models to provide a 360° augmented reality experience. Overall, combining the model, schedule, and reality capture in one environment provided near real-time insights into progress.
The Results
By leveraging Reconstruct’s Reporter App vs. the manual process, KBDG reported a 30% decrease in the time required to provide on-site construction progress updates to the master schedule.
The team realized additional benefits:
- SCHEDULE ADHERENCE: The project was completed four weeks ahead of schedule. While many factors contributed to this outcome, Reconstruct played a major role.
- CHANGE ORDER REDUCTION: The only change orders on the project were owner-driven; there were none from subcontractors.
- TRAVEL COST REDUCTION: Remote monitoring of construction progress by key stakeholders, such as project executives and the owner, resulted in 50% less time and travel costs.
- SAFETY: By viewing Reconstruct’s reality model, the safety manager identified and mitigated several potential safety issues.
- HISTORICAL RECORD: Reconstruct documented the construction process, making it easier for KBDG and the owner to understand as-built conditions, especially in hidden places behind walls or above ceilings.

What is 4D BIM? Learn the Definition & Benefits
4D BIM integrates “time” with BIM, enabling step-by-step visualization of detailed construction schedules. 4D BIM is also referred to as 4D scheduling.
