Implementation of demonstration experiment to utilize an autonomous drone for streamlining progress management at construction site as a work for MLIT’s FY 2022 Model project for building production and operation & maintenance process facilitation by utilizing BIM (leading entrepreneur type)
Toyo Construction Co., Ltd. (Head office: Chiyoda city, Tokyo Metropolis, President and
Representative Director: Kyoji Takezawa) has implemented a demonstration experiment to
utilize an autonomous drone for the remote supervision method of works (streamlining of
progress management), in collaboration with SENSYN ROBOTICS, Inc. (Head office: Shibuya city,
Tokyo Metropolis, CEO: Takuya Kitamura).
This demonstration experiment was conducted as a work by Toyo Construction for the FY 2022
Model project for building production and operation & maintenance process facilitation by utilizing
BIM (leading entrepreneur type), which was adopted by MLIT.
For streamlining the progress management at construction sites, the experiment was conducted to
explore the effects of the new supervision method of works utilizing the construction BIM model
with an autonomous drone, and as a result of the exploration, we were able to confirm the expected effects.
Skydio Dock
Autonomously flying drone
The demonstration experiment was conducted with preparation of the automatic flying route using
the “Skydio Dock”, a drone site dedicated for Skydio machine, and with autonomous flying through
the cloud platform.
Since the Skydio machine is equipped with the Visual-SLAM* technology, by which the self-localization
is possible even indoors where a radio wave of GNSS (Global Navigation Satellite System) is not available,
the machine is capable to fly, with AI processing, automatically avoiding the obstacles such as cables hung
from the ceiling. Moreover, the machine is an autonomous drone that is capable to fly autonomously only
by pushing the takeoff button from a remote place, to fly autonomously through a narrow path such as stairs,
and to come back automatically to the original Dock place, and automatic charging is also available.
In the experiment, firstly, the dedicated application was activated on the PC screen, then the local operator
prepared the flight schedule by designating the flight route and photographing points. Next, according to
the flight plan, we had the drone accomplish the automatic takeoff from the Skydio Dock and take videos
of the flying route as well as still pictures at the designated points
As a result of the demonstration experiment, it was confirmed that the machine was perfectly doable to fly
at night or in a low luminance environment peculiar to construction sites, to avoid obstacles, and to move
through plural stories, and it successfully obtained the image data required to confirm the construction
status of each room.

Also, a system has been developed for confirming the captured image data, by linking the image data
captured by the drone to the point data set on the BIM model shared on the cloud platform.
Both companies will set up a system for effective management & sharing of image data utilizing the BIM,
and will reduce the working time required for construction management / administrative tasks.
■Overview of the demonstration experiment
Date of activity: November 25, 2022 and December 19, 2022
Place: (working title) New construction for Tokyo Information Design Professional University (Komatsugawa, Edogawa city)
Contents: 1. Automatic flight from a remote place using Skydio Dock (Drone site)
2. Automatic flight under the condition of construction site
3. Utilization of captured data for construction management

TOYO BIM Forum ２０２３~Architecture DX: Development from BIM Process to Data Science･Generative AI･Metaverse~ was held.
Toyo Construction Co., Ltd. (President and Representative Director: Kyoji Takezawa) held the
“TOYO BIM Forum 2023” in the meeting room of Head Office on March 17. This forum, which
has been held eight times now, was held allowing online participation by hybrid method, in
addition toparticipation in the meeting room, with participation of over 80 officers and staff.
At the opening, Mr. Hiromi Hirata, Director and Vice President Executive Officer & General
Manager ofArchitectural Construction Div., told that construction industry is rapidly changing
by the automation of construction process and the introduction of technologies to realize
optimization, and that the construction DX, BIM and AI are the core of this innovation as well
as the critical element to form the future of construction industry, and that it is expected that
many people will notice various issues of construction industry through the utilization of these
technologies for the issues such as reduction of CO2 emission amount or labor shortage and
aging of workers.
Mr. Hirata, General Manager of Architectural
Construction Div.
For this forum, we invited industry leaders, professionals and engineers, as external partners.
In the morning session, following the reports of the design review conducted this fiscal year,
the visualization of findings that arose during the process of design verification, and the
metaverse, we exchanged views on the possibility that the image generation by AI may have
an influence on the implication of design, etc. In the afternoon session, the achievement was
reported, with partner companies that jointly addressed the challenges in the BIM model
project, and in a related move, a panel discussion was presented. Each of the verified
challenges is the critical technology for the future construction DX, and we had a lively
exchange of views about the necessity of continuous technology development, etc.

of DX Group of Architectural Construction Div.
This BIM Forum 2023 provided a valuable opportunity to share information and exchange
views with industry specialists on the latest technological trends and challenges that forge the
future of construction industry. Regarding the challenges related to the construction BIM, Mr.
Sasaki, Project Manager who is working on the utilization of overseas human resources as an
example of the challenge on the front line, made a case report, and it was confirmed that the
significant reduction in working hours and improvement of work efficiency, which is necessary
for the BIM modelization, have been realized and that we will aim to utilize it proactively.
Also, regarding the construction BIM training for staff at sites, the achievement of
experience-based training that was introduced in FY 2022 was reported. Experience-based
training, aiming to hold a construction BIM coordination meeting led by the site (a meeting to
discuss the interference check and balance utilizing the three-dimensional model), handles the
process to exchange findings on the cloud platform (Autodesk BIM360), contents of which are
practical in that the construction staff indicate the interference points and balance as an
individual specialty contractor and provide answers. In the questionnaire replies after the
training, it was reported that 87% of staff wanted continuing training.
