Construction of Prime Delica Toyota Factory No. 2

Achieved a high level of construction through cleanliness management, room temperature control, and condensation measures.

Prime Delica Toyota Factory No. 2 is the second Prime Delica factory in the Tokai region to produce and distribute prepared dishes and desserts for Seven-Eleven convenience stores.

As the number of new Seven-Eleven stores in the Tokai and Hokuriku regions increased rapidly, boosting demand for products, the company decided to build a second factory.

Points of project


Construction completed in just 5.5 months

With only one entrance for construction vehicles at the construction site at Noiri, Sanagecho, Toyota in Aichi Prefecture, we were requested to make a detailed loading plan and schedule before construction. There were also restrictions on choosing temporary equipment and heavy machinery, so we had to carefully consider a temporary equipment plan as well.
In addition, it took a long time to complete discussions with the Council for Conservation of Water Quality on the Yahagi River and the Yahagi River Fisheries Union and to obtain approval. As a result, construction started about 1.5 months later than planned, so we had to complete it in just 5.5 months. To make up for lost time, we modified the original schedule, made a daily schedule sheet for detailed schedule management, and managed personnel, progress, and earned value. When we happened to run behind schedule, we managed the schedule more strictly to catch up on the week’s work.


Cleverly devised progress management

We divided the entire construction into (five) smaller construction sections so that no forced or wasteful work would be generated in each section. Since it was very difficult to secure many workers at that time, we focused on keeping up with the schedule using a limited number of workers.
Regarding the specifications mentioned in the drawing set, we replaced time-consuming methods with time-saving ones. We also worked on time-consuming production in the early stages of construction concurrently with other production work. Electrical and mechanical work accounted for a large proportion in this project, so it was a challenge regarding how to proceed with the work. What we did was finish up the external electrical and mechanical work, including architectural work, before putting up external scaffolding.
Even for the internal work, we checked the drawings to identify areas that required piping and wiring for electrical and mechanical work and determined which areas needed to start with electrical and mechanical work or architectural work to raise the work efficiency.


Collaboration of “client,” “architect,” and “contractor”

“People in this region are waiting for the factory to be completed,” the leader of the Sanage region often said. At the end of every month, we reported the construction progress at a general session of the region. This was a great opportunity for us to hear complaints and requests from the residents. We were able to proceed with the construction smoothly because many people were so supportive.

Thanks to all the support and cooperation from the client and the architectural company, we successfully completed the construction in a very short period. This was thanks to efforts made through the collaboration of “client,” “architect,” and “contractor.”
