We will conduct a detailed investigation of the extent and degree of damage necessary for the design and estimation of repair work, supporting a well-founded repair plan.
"I understand that repairs are necessary, but there is no data to support where and to what extent repairs should be made." — Detailed understanding of the extent and degree of damage is essential for the design and estimation of repair work. There are often cases where records from regular inspections do not provide sufficient information for repair design. This service conducts more detailed close visual inspections, sound tests, and damage measurements than regular inspections, obtaining data that can be used for the design and estimation of repair work. We will create reports that serve as the basis for determining the extent of damage, selecting repair methods, and calculating quantities. We also accommodate collaboration with design consultants and construction companies.
