SCOPE OF WORK
Periodic Survey of Specified Buildings
"Periodic Survey of Specified Buildings" is a survey of an entire building based on the periodic reporting requirements set forth in Article 12, Paragraphs 1 and 3 of the Building Standard Law.
Buildings that meet the requirements for size and number of stories are designated as "specified buildings," and the owner or manager of such buildings is obligated to conduct periodic building inspections and reports.
There are six main survey items: "site and ground," "building exterior," "rooftop and roof," "building interior," "evacuation facilities," and "emergency entrances."
Inspections of solar power plants and solar carports include deterioration and damage to roofs and exterior walls, unevenness and tilting due to ground subsidence, site drainage conditions, and seismic countermeasures.
The above surveys are conducted by either a first-class architect, second-class architect, or specified building surveyor, and the survey results are entered in the inspection report distributed by each municipality and submitted to the specified administrative agency.
- A new periodic reporting system for special buildings was enacted on June 1, 2008, in response to a fire accident in a building that was not managed in a lawful manner.
Periodic Building Equipment Inspections
"Periodic Inspection of Building Facilities" is an investigation of building facilities based on the periodic reporting obligation set forth in Article 12, Paragraphs 1 and 3 of the Building Standard Law.
