Construction Services

We offer maintenance inspections on and the option to modify and repair products delivered to the client and to perform other such services. We can also accommodate requests pertaining to competitors’ products and the installation of our products. Feel free to submit an inquiry if you have any questions. We also accept requests for different kinds of jobs relating to delivered products as they pertain to the commissioning (performance verification) of equipment as carried out by the client.

Regular Maintenance Inspections

We conduct maintenance inspections to ensure that products can be safely used for an extended period of time. Regular maintenance inspections can expect to prevent product degradation, as well as sudden accidents through the early detection of abnormalities. Where an inspection reveals an abnormality, we will make suggestions for remediation that are ideal for your particular system.

Making Modifications in Switchboards

We will undertake modification work to be performed on switchboards, control panels, distribution boards, and more. For example, we will change the capacity or workings of equipment inside a switchboard or replace equipment that has undergone aged deterioration.

Commissioning Services

Recent years have seen an increase in the number of cases involving the concept of commissioning (performance verification) to ascertain required performance levels for a system and verify such performance levels as part of the process of constructing foreign-affiliated data centers and other such facilities. We provide related services for the commissioning of equipment systems and the conducting of performance verification testing on delivered products by clients.
