ご挨拶

引き受けた仕事に責任を持ち、技能で応える

三城建機は、1965年の創業以来、コンクリート圧送の専門工事業者として、多くの建設現場に携わってきました。私たちが大切にしているのは、引き受けた仕事に責任を持ち、最後までやり遂げることです。

工事が進むにつれて、施工条件が厳しくなったり、当初は見えなかった課題が生じたりすることがあります。そうした局面でこそ、専門工事業者の力が問われます。現場の条件や制約を見極め、関係者と協議し、安全と品質を確保できる方法を考える。必要に応じて機械や配管、作業体制を見直し、施工を完遂するために力を尽くす。その姿勢を、私たちは貫いていきたいと考えています。

それを支えるのが、長年の現場で培ってきた技能と経験です。コンクリートの性状を把握し、コンクリートポンプの性能を引き出し、打込み・締固めを担う職種と連携する。建設技術の進歩とともに高まる技術・品質の要求に、一つひとつ応えてきた蓄積が、今日の三城建機の土台となっています。

この力を将来につなぐため、人材育成にも取り組んでいます。若い社員や外国人社員が専門技能を身につけ、責任ある役割を担えるよう、日本語の習得や資格取得を支援する。また、熟練者が体力的に現場作業を続けにくくなっても、施工の検討や後進の指導に経験を生かせるようにする。一人ひとりの成長と、長く力を発揮できる働き方の両方を大切にします。

AIやロボットなどの新しい技術にも、可能性を感じています。日々の判断や工夫を教育に役立て、事務や身体的な作業の負担を減らす。さらに、人員や作業方法の制約を緩和し、対応できる仕事の幅を広げる。実際の効果と課題を確かめながら、現場で役立つ使い方を探っていきます。

難しい場面でも、ともに考え、頼りにしていただける会社であること。三城建機は、社員と協力会社の力を結集し、責任ある施工を通じて、お客様の信頼に応えてまいります。

Delivering on Our Commitments through Expertise and Craftsmanship

Since its founding in 1965, Sanjoh Kenki Inc. has served numerous construction projects as a specialist concrete pumping contractor. At the heart of our work is a clear commitment: to take responsibility for every project we undertake and see it through to completion.

As construction progresses, site conditions may become more demanding, and challenges that were not apparent at the outset may emerge. It is in these situations that a specialist contractor’s capabilities are put to the test. We assess the conditions and constraints, consult with everyone involved, and develop solutions that safeguard safety and quality. Where necessary, we review our equipment, pipeline arrangements, and work teams, making every effort to bring the work to completion. This is the approach we remain committed to.

Underpinning this commitment are the skills and experience we have developed over decades on site. We assess the properties of the concrete, make full use of our concrete pumps’ capabilities, and coordinate closely with the teams responsible for placing and compacting the concrete. Our experience in meeting increasingly demanding technical and quality requirements as construction technology advances forms the foundation of Sanjoh Kenki Inc. today.

To carry these capabilities forward, we invest in developing our people. We support younger employees and employees from overseas in learning Japanese and obtaining qualifications, helping them acquire specialist skills and take on positions of responsibility. We also seek ways for experienced workers to contribute to construction planning and mentor the next generation, even when the physical demands of site work become difficult to sustain. We value both individual growth and working arrangements that enable people to continue contributing over the long term.

We also see potential in new technologies, including AI and robotics. We aim to use the judgment and practical ingenuity developed in our daily work to support training and reduce administrative workloads and physically demanding tasks. These technologies may also help ease staffing and operational constraints, expanding the range of work we can undertake. We will explore practical applications on site while carefully evaluating their benefits and challenges.

We strive to be a company our customers can rely on—a partner that works with them to find solutions, even in difficult circumstances. By bringing together the strengths of our employees and partner contractors, Sanjoh Kenki Inc. will continue to earn our customers’ trust through responsible project delivery.
