Among production engineers, those involved in factory construction are just a handful.
During my active career, I had the opportunity to experience three projects: two new constructions and one renovation of an existing facility. I would like to share this valuable experience with you.
1. Factory Construction and Production Engineers

In addition to experience as production engineers, factory construction requires a comprehensive understanding and know-how of building construction, equipment installation, and more. This is not something that can be quickly learned or acquired through short-term training; it often involves on-the-job training (OJT) with experienced seniors and learning from failures, which are valuable assets in themselves.

The process from factory building and maintenance to the installation, adjustment, and operation of equipment after completion is fraught with continuous troubles. Coordinating daily with construction companies, equipment manufacturers, installation teams, and transportation companies to solve problems on-site is crucial for managing the construction schedule as planned. Safety management becomes especially important as fires or injuries can significantly impact the startup phase.

Furthermore, the costs related to production preparation can be very high, making it important for production engineers to manage these expenses within the budget. Therefore, having a measure for construction duration and costs is also necessary.

2. Factory Startup: New Construction in Japan

  • As the main factory became too cramped, we commissioned a major general contractor to construct a two-story factory (with a total floor area of 128,800 sqm) in an industrial park, divided into phases I through III.
  • I was part of a three-person team responsible for Phase II of the construction (with a total floor area of 52,400 sqm).


  • The construction company resolved issues that arose during the construction according to the architectural blueprints. During the finishing stages of construction, there were many adjustments related to the preliminary installation of production equipment and foundational work (related to the building).

    Due to its proximity to the sea, the entire site was raised, and special construction methods were employed, such as driving piles down to the bedrock on reclaimed land. At the time, this resulted in the construction of Japan’s largest single building exceeding 120,000 sqm. Furthermore, the factory was designed to optimize information and logistics flow from the entrance to the exit.

    3. Factory Startup: Europe

  • We decided to establish a new factory in Eastern Europe and entrusted a major general contractor with the construction of a single-story factory (with a total floor area of 50,000 sqm).
  • Two of us were responsible for this project.


  • Due to various problems arising daily, we held regular meetings every day. We organized the issues that occurred each day, assigned responsibilities, set deadlines, and followed up daily. Amidst the new challenges (country, ethnicity, language, European customers, collaborating companies, etc.), we established a European hub.”

    4. Renovation of an Existing Factory

  • We transformed an aluminum piping factory (two-story building with a total floor area of 5,000 sqm) into a commercial packaging facility.
  • Two of us were in charge of this project.


  • After relocating the piping equipment, we cleared out the remaining discarded equipment, as well as air conditioning ducts, air pipes, steam pipes, electrical ducts, and wires that were hanging from the factory’s beams.

    Once the factory was cleared, we conducted inspections and maintenance on various systems including the substation, industrial water supply devices (inspection and disinfection), the septic system, repairs for leaks, air conditioning systems, and replacement of shutters including the installation of quick shutters. We also worked on the factory’s oil recovery facilities, supported notifications to river management organizations, and provided assistance with notifications for specific facilities.

    We implemented a systematic commercial packaging line that includes milk run for part pickups and multiple deliveries, and introduced a cardboard box manufacturing machine capable of producing boxes in the smallest unit of one box.

    Currently, there is a trend of recovery from the COVID-19 pandemic, and it is anticipated that securing construction companies and workers will become more difficult. In response to the labor shortage, it is considered necessary to elevate the level of construction management through the generation of flexible ideas and improvements in construction work.

    The Consultant Who Wrote This Column
    Takeshi Kawabata

    A former member of the Production Engineering Department at DENSO Corporation.
    He acquired and implemented the Toyota Production System through direct experience with Toyota Motor Corporation. Additionally, he has been involved in the construction of two new factories and the renovation of one existing factory, managing construction schedules and budgets as planned, and achieving optimization of information and logistics from the factory entrance to exit. He was responsible for overseeing the construction of Japan’s largest single factory building at the time, covering 120,000 square meters.

    3 reasons why we are chosen REASON

    REASON 1

    Improvement experience of
    more than 1,500 companies in 40 countries

    There must be the shop floor issues that cannot be solved by your own company alone. Improvements and reforms for manufacturing industry to survive, regardless of country or industry, need development of your human resources through practical experiences of improvement, and strengthening of your production system base.

    REASON 2

    Consulting that shop floor workers
    acknowledge our superiority and be pleased

    In conventional consulting styles, there was a distance between consultant and the shop floor because it was promoted mainly consultant and management executives. Our consultant can provide a guidance without a distance between consultant and the shop floor through the guidance based on the “seeds of improvement” in a concrete way, instead of “finding fault” like a critic.

    REASON 3

    Continuous improvement will continue
    even after the end of guidance

    While strengthening “human resource development”, we focus on the “overall flow” from design to purchasing, manufacturing, logistics, and production control, and provide guidance that matches the actual situation of your company. Continuous improvement will continue even after the end of guidance through the guidance that is acceptable to the shop floor workers.

    Consultants from major companies
    with experience in over 40 countries will respond.
