施工（せこう、sekou）
- construction

The Japanese word 施工 (せこう) primarily means "construction," "execution," or "implementation." It refers to the act of carrying out a plan, design, or project, particularly in the context of building, engineering, or manufacturing. It encompasses the actual work performed to bring something into existence, not just the planning stages. This can involve a broad range of activities depending on the specific project, such as assembling materials, installing equipment, or performing specialized tasks. The scope is quite vast, ranging from large-scale construction projects to smaller-scale implementations.

It is a very common word to see in project management and technical documentation. It's less common in casual everyday conversation.

施工 (せこう) is written with the kanji 施 (meaning "to perform" or "to implement") and the kanji 工 (meaning "work" or "construction"). The reading is usually せこう.
