Just as if a tailor would carefully make the best fitting clothes for you, we tailor our services to make your dreams come true, through our knowledge and solid experience in building and M.E.P.(Mechanical, Electrical, and Piping) construction. This is our "Made-to-Order" philosophy.
In order to answer to a variety of requests, we have developed a system to handle all phases of your construction project. From consulting to construction, residential to commercial, equipment to building, and even property management… we do our best to accommodate all your needs.
We’ve gained trust of our clients by providing the best service possible. Our strongest expertise lies in M.E.P. construction, which includes equipment renewal, renovation, and maintenance services for upscale residential, multi-dwelling units, office buildings, medical facilities, factories, and so on. We also believe that the equipment maintenance after construction is one of our most important tasks, and we provide support, 365 days a year, to solve any issues that arise.
Air conditioning, plumbing, and electrical systems are the necessities of everyday life and must be first and foremost functional, but also safe, energy-efficient, and sustainable. "From perfect planning through perfect after-care", we provide comfortable environments for you to enjoy.
