Condominium Inspections and Guarantee
Quality inspection + housing performance evaluation by a third-party Add an independent third-party to make checks
A third party that has no direct relationship with the design firm or construction company will check 28 items in 9 areas to see if the building is safe and can be lived in comfortably.
In addition, there are two types of housing performance evaluation, namely, the “Design housing performance evaluation” and the “Construction housing performance evaluation.”
Rebar and concrete layout inspections conducted by the third party are usually only conducted on specific floors designated by the Building Standards Act and laws related to the promotion of a building’s quality assurance (Quality Assurance Law).
Floors for which there is no obligation to have a third-party inspection will be inspected by a building contractor or manager, and a quality inspection will be carried out by Bureau Veritas Japan Co., Ltd.
A third-party quality inspection is conducted on every floor to check the “structural slits,” which are used to prevent pillars and beams from breaking in the event of an earthquake, in a way similar to that of a “tensile strength inspection,” which prevents tiles from peeling, and an inspection results report is issued after the inspection has been completed.
The standard for Hajime Construction is to make sure our customers can live with peace of mind and security, which we achieve by using our own strict quality standards which are greatly superior to the inspection standards of the “Building Standards Act” and the “Quality Assurance Act” stipulated by the national government and are unrivaled by other companies.
